PHP enabled web server
Apache (recommended) – the Bitrix software was developed for Apache 2.0 and higher.
Bitrix Site Manager and Bitrix24 require PHP version 5.3.x or higher. It is recommended that you use the latest stable release of PHP to prevent PHP failures and to provide the maximum security at the server side.
The following PHP extensions are required:
. UTF-8 is available for Oracle and MySQL. To ensure the correct support of UTF encryption, check if the mbstring module is installed in PHP. In this context, the php.ini file in the PHP settings must include:
Database server support
MySQL version 5.0 and higher is recommended.
To support MySQL, the system requires the MySQL support for PHP to be installed.
Web server configuration
For proper functioning, Bitrix Site Manager requires the following parameters to be set.
The following PHP parameters are essential.
- memory_limit = 64M;
Maximum amount of PHP memory required by the system core.
: this parameter can be changed:
- by editing the file php.ini directly;
- from within a script by calling ini_set("memory_limit", "64M");
This call is added to /bitrix/php_interface/dbconn.php at the installation time using the user-supplied value;
- in the file .htaccess using the directive: php_value memory_limit 64M
- in the file httpd.conf using the directive: php_admin_value memory_limit 64M
: parameters can be altered from within the .htaccess file if the following conditions are met:
- Apache (or compatible) web server is used;
- .htaccess files are processed by a web server, which means that the web server configuration file (httpd.conf) contains the directive AllowOverride set to All or any value other than None;
- PHP is installed as an Apache module (if PHP runs as CGI all the required parameters must be set when compiling PHP)
- file_uploads = On;
The parameter defines whether files can be uploaded to a server or not.
Additionally, the following variables are also to be set:
- upload_tmp_dir = <folder name>
- upload_max_filesize = <required file size limit>
Important! It is essential that the specified directory exists, and a current user (under which the web server runs) is granted the write permissions for this folder.
- Proper PHP session handling is the indispensable condition. You are recommended to check that the folder where the session files are saved exists.
Note: if the parameter session.save_path is missing from php.ini, the default value of /tmp is used.
If the server URL's happen to contain the PHPSESSID=...
parameter, you hide it as follows:
- Add the line session.use_trans_sid = 0 to php.ini;
- In .htaccess, add the following directive: php_flag session.use_trans_sid off
The demo site has this line included in .htaccess, you can uncomment it if required.
