2.1 Requirements for phpMyFAQ
phpMyFAQ addresses a database system via PHP. In order to install it locally you will need a web server that meets the following requirements:
- version 8.1 or later
- memory_limit = 128M (the more the better)
- cURL support
- GD support
- XMLWriter support
- JSON support
- Filter support
- SPL support
- FileInfo support
- Web server (Apache 2.x or nginx 1.0+)
- Database server
- MySQL (via MySQLi extension)
- Microsoft SQL Server 2012 and later
- MariaDB (via MySQLi extension)
- Percona Server (via MySQLi extension)
- Search engines (optional)
- Elasticsearch 6.x or later
- correctly set: access permissions, owner, group
- Docker (optional)
You can only run phpMyFAQ successfully with constraints affect the directives open_basedir and disable_functions, which can be set in the central php.ini or the httpd.conf respectively.
In case PHP runs as module of the Apache, you will have to be able to do a chown on the files before installation. The files and directories must be owned by the web server's user.
You can determine which versions your web server is running by creating a file called info.php with the following
<?php phpinfo(); ?>
Upload this file to your webspace and open it using your browser. The installation-script checks which version of PHP is installed on your server. Should you not meet the requirements, you cannot start the installation process.
In case you're running PHP before 8.1 you cannot use phpMyFAQ.
phpMyFAQ uses a modern HTML5/CSS3 powered markup. The supported browsers are the latest Mozilla Firefox (Windows/macOS/Linux), the latest Safari (macOS/iOS), the latest Chrome (Windows/macOS/Linux), the latest Opera (Windows/macOS/Linux) and Microsoft Edge (Windows/macOS/Linux).
We recommend to use always the latest version of Firefox, Chrome, Safari, Opera or Microsoft Edge.
2.2.1 Classic Shared Web Hosting
You can install phpMyFAQ via one of the provided packages as .zip or .tar.gz or using Git. If you choose our package, download it and unzip the archive on your hard disk.
If you want to use Git, please run the following commands on your shell:
$ git clone firstname.lastname@example.org:thorsten/phpMyFAQ.git 3.2
$ cd phpMyFAQ
$ curl -s https://getcomposer.org/installer | php
$ php composer.phar install
$ curl -o- -L https://yarnpkg.com/install.sh | bash
$ yarn install
$ yarn build
You can modify the layout of phpMyFAQ using templates. A description of how this is done can be found here. Copy all unzipped files to your web server in a directory using FTP. A good choice would be the directory faq/.
Important: Writing permission for your script is needed in this directory to be able to write the file config/database.php during installation. The installation script will stop when your web server isn't configured as needed.
It might help to set chmod 775 to the whole phpMyFAQ directory to avoid problems during the installation. If you're running a very restrictive mod_php installation you should keep the chmod 775 for the following files and directories even after the successful installation:
- the directory attachments/
- the directory config/
- the directory data/
- the directory images/
All other directories shouldn't be world-writable for your own security.
Note: If you're running SELinux, you may need further configuration or you should disable it at all.
The database user needs the permissions for CREATE, DROP, ALTER, INDEX, INSERT, UPDATE, DELETE and SELECT on all tables in the database.
2.2.2 Cloud Hosting via Docker
You first need a database, let's try with a MariaDB container:
$ docker run -ti -n phpmyfaq-db mariadb
Then start the phpMyFAQ web application:
$ docker run -ti --link phpmyfaq-db:db -p 8080:80 phpmyfaq/phpmyfaq
Open your browser and type in the following URL:
Step 1: Database server
Substitute www.example.com with your actual domain name. When the site is loaded, first select the database you want to use for phpMyFAQ. The loaded database extensions from PHP are listed in a select box. Then enter the address of your database server (e.g. db.provider.com), the database port, your database username and password as well as the database name. The database have to be created with UTF-8 character set before running the installation script. You can leave the prefix-field empty. If you are planning on using multiple FAQs in one database you will have to use a table prefix, though (i.e. sport for a sports FAQ, weather for a weather FAQ, etc.). Please note that only letters and an underline: "_" can be used as the prefix. If you want to use SQLite, you only have to select a path to the database file of SQLite.
Step 2: LDAP or Microsoft Active Directory support
If PHP was compiled with the LDAP extension you can add your LDAP or Microsoft Active Directory information, too. Then you can to insert your LDAP or Microsoft Active Directory information as well.
Step 3: Elasticsearch support
If you want to use Elasticsearch, you can activate this in the third step. You just have to add at least one Elasticsearch node and the index name.
Step 4: Admin user setup
In addition, you can enter your language, default here is English. Furthermore, you should register your name, your email address and - very importantly - your password. You must enter the password twice, and it has to be at least eight characters long. Then click the button "install" to initialize the tables in your database.
2.4 First Steps
You can enter the public area of your FAQ by entering
into your browser's address field. Your FAQ will be empty and presented in the the standard layout.
To configure phpMyFAQ point your browser to
Please use your chosen username and your password for your first login into the admin section.
Some variables that does not change regularly, they can be edited in the file config/constants.php. You can change the
- the time zone of your server (default: "Europe/Berlin")
- the timeout in the admin section (default: 300 minutes)
- the timeout warning pop-up in the admin section (default: 5 minutes)
- the solution id start value (default: 1000)
- the incremental value of the solution id (default: 1)
- the number of records in the Top10 (default: 10)
- the number of the latest records (default: 5)
- flag with which Google site map will be forced to use the current phpMyFAQ SEO URL schema (default: true)
- the number with which the Tags Cloud list is limited to (default: 50)
- the number with which the autocomplete list is limited to (default: 20)
- the default encryption type for passwords
2.5 Notes regarding the search functionality
- The boolean full-text search will only work with MySQL and if there are some entries in the database (5 or more). The term you are looking for should also not be in more than 50% of all your entries, or it will automatically be excluded from search. This is not a bug, but rather a feature of MySQL.
- The search on other databases is using the LIKE operator currently.
- To improve the search functionality you should consider using Elasticsearch.
2.6 Automatic user language detection
To set the default language in your browser you have to set a variable that gets passed to the web server. How this is done depends on the browser you are using.
- Mozilla Firefox: Tools -> Options -> Content -> Languages
- Google Chrome / Microsoft Edge / Opera: Settings -> Details -> Language settings
- Safari uses the macOS system preferences to determine your preferred language: System preferences -> International -> Language
2.7 PHP settings
- We recommend using a PHP accelerator or OpCode cache
- Allocate at least 128 MB of memory to each PHP process
- Required extensions: GD, JSON, Session, MBString, Filter, XMLWriter, SPL, FileInfo
- Recommended configuration:
memory_limit = 128M file_upload = on
2.8 Enabling support for SEO-friendly URLs
Apache Web server
If you want to enable the search engine optimization you have to activate the mod_rewrite support in the admin backend
in the configuration page. You also have to edit the path information for the "RewriteBase". If you installed phpMyFAQ
on root directory "/" you should set in
RewriteBase / Please check, if
AllowOverride All is set correctly in your
httpd.conf file so that the .htaccess rules work.
nginx Web server
If you want to enable the search engine optimization you have to copy the rewrite rules in the file nginx.conf to your nginx.conf. Then you have to activate the URL rewrite support in the admin backend in the configuration page.
2.9 Enabling LDAP or Microsoft Active Directory support
If you're entered the correct LDAP or Microsoft Active Directory information during the installation you have to enable the LDAP or Microsoft Active Directory support in the configuration in the admin backend. Now your user can authenticate themselves in phpMyFAQ against your LDAP server or a Microsoft Active Directory server.
If you need special options for your LDAP or ADS configuration you can change the LDAP configuration in the admin configuration panel.
If you want to add LDAP support later, you can use the file config/ldap.php.original as template and if you rename it to config/ldap.php you can use the LDAP features as well after you enabled it in the administration backend.
2.10 Using Microsoft Entra ID
You can use our experimental Microsoft Entra ID support for user authentication as well. App Registrations in Azure are used to integrate applications with Microsoft Azure services, allowing them to authenticate and access resources securely. Follow these steps to create an App Registration in Microsoft Azure:
- Azure account with appropriate permissions.
Step 1: Sign in to Azure Portal
- Open your web browser and navigate to the Azure Portal.
- Sign in with your Azure account credentials.
Step 2: Create a New App Registration
- In the Azure Portal, click on "Entra ID" in the left-hand navigation pane.
- Under "Entra ID," click on "App registrations."
Step 3: Register a New App
- Click the "+ New registration" button.
Step 4: Configure the App Registration
- In the "Name" field, provide a name for your App Registration, e.g. "phpMyFAQ".
- Choose the supported account types that your application will authenticate: "Accounts in this organizational directory only"
- In the "Redirect URI" section, specify the redirect URI where Entra ID will send authentication responses:
- Click the "Register" button to create the App Registration.
Step 5: Configure Authentication
- After the registration is created, go to the "Authentication" tab in the App Registration settings.
- Under "Platform configurations," select the appropriate redirect URI type: Web
- Configure the Redirect URIs as needed for your application.
- Save the changes.
Step 6: Note Application Details
- Make note of the "Application (client) ID." This is your application's unique identifier.
- If your application requires client secrets, go to the "Certificates & secrets" tab to create and manage client secrets.
Step 7: Create Azure config file
- Copy the file
./config/azure.php.originaland name it
- Add the Tenant ID, the client ID and the secret from Step 7 and save the file
- Then, activate Microsoft Entra ID support in the administration under "Security"
2.11 PDF export

- supports automatic page numbering and page groups;
- supports automatic line break and text justification;
- supports JPEG and PNG images natively, all images supported by GD (GD, GD2, GD2PART, GIF, JPEG, PNG, BMP, XBM, XPM)
2.12 Static solution ID
phpMyFAQ features a static solution ID which never changes. This ID is visible next to the question on a FAQ record page. You may think why do you need such an ID? If you have a record ID 1042 it is now possible to enter only the ID 1042 in the input field of the full-text search box, and you'll be automatically redirected to the FAQ record with the ID 1042. By default, the numbers start at ID 1000, but you can change this value in the file inc/constants.php. You can also change the value of the incrementation of the static IDs.
2.13 Spam protection
phpMyFAQ performs these three checks on public forms:
- Check against IPv4 and IPv6 Network address
- Check against banned words
- Check against the captcha code (builtin or Google ReCaptcha)
The IPv4 and IPv6 Network addresses can be added or removed in the configuration panel in the administration backend. If you want to add banned words to phpMyFAQ, then you have to edit the file src/blockedwords.txt. Please add only one word per line.
By default, phpMyFAQ uses the builtin captcha functionality. If you want to use Google ReCaptcha v2, you can enable the support for Google Recaptcha by adding your site and secret key. You can get the keys from Google.
phpMyFAQ supports encrypted attachments. The encryption uses the AES algorithm implemented in mcrypt extension (if available) or with native PHP Rijndael implementation. The key size vary depending on the implementation used and can be max 256 bits long. Use of mcrypt extension is strongly recommended because of performance reasons, its availability is checked automatically at the run time.
Please be aware:
- Disabling encryption will cause all files be saved unencrypted. In this case you'll benefit sparing disk space, because identical files will be saved only once.
- Do not change the default attachment encryption key once files was uploaded. Doing so will cause all the previously uploaded files to be wrong decrypted. If you need to change the default key, you will have to re-upload all files.
- Always memorize your encryption keys. There is no way to decrypt files without a correct key.
- Files are always saved with names based on a virtual hash generated from several tokens (just like key and issue id etc), so there is no way to asses a file directly using the name it was uploaded under.
- Download continuation isn't supported.
2.15 X (Twitter) support
phpMyFAQ supports X (Twitter) via OAuth. If you enable X (Twitter) support in the social network configuration and add phpMyFAQ as a X (Twitter) application on X (Twitter), all new FAQ additions in the administration backend will also post the question of the FAQ, the URL of the FAQ and all tags as hashtags to X (Twitter), e.g. the tag "phpMyFAQ" will be converted to "#phpmyfaq".
This feature is deprecated and will be removed in phpMyFAQ 4.0.
2.16 Server side recommendations
MySQL / Percona Server / MariaDB
interactive_timeout = 120
wait_timeout = 120
max_allowed_packet = 64M
2.17 Syntax Highlighting
The bundled highlight.js syntax highlighting component will find and highlight code inside of <pre><code> tags; it tries to detect the language automatically. If automatic detection doesn't work for you, you can specify the language in the class attribute:
The list of supported language classes is available in the class reference. Classes can also be prefixed with either language- or lang-.
To disable highlighting altogether use the "nohighlight" class:
2.18 Elasticsearch Support
To improve the search performance and quality of search results it's possible to use Elasticsearch. You need a running Elasticsearch instance accessible by phpMyFAQ via HTTP/REST. You can add the IP(s)/Domain(s) and port(s) of your Elasticsearch cluster during installation or later by renaming the Elasticsearch file located in the folder config/. If you choose to add this during installation, the file will be automatically written and the index will be built. If you enabled Elasticsearch support in the admin configuration panel, you can create, re-import and delete your index with a user-friendly interface.
