Very often, the user needs to change the PHP settings one way or another to work with scripts. There are two possible options.
Case 1. It is necessary to make changes at the PHP compilation (assembly) level (adding modules, changing PHP_INI_SYSTEM system options).
Case 2. It is enough to change the value of one or more options that have the changeability status of PHP_INI_PERDIR or PHP_INI_ALL.
Recall the meaning and interpretation of the constants PHP_INI_*:
| PHP_INI_USER | 1 | The option can be set in user scripts |
|---|---|---|
| PHP_INI_PERDIR | 2 | The option can be set to php.ini, .htaccess or httpd.conf |
| PHP_INI_SYSTEM | 4 | The option can be set to php.ini or httpd.conf |
| PHP_INI_ALL | 7 | The option can be installed anywhere |
In the first case , when we need to change the PHP configuration by adding new modules (imap, templates, curl), with which our modular PHP is not built. If so, you need to build your PHP. After the build, we recommend copying our INI file:
/usr/local/etc/php.inior
/usr/local/etc/php.inidepending on the type of SAPI interface used (cgi or cli).
In the second case, when you do not need to use any additional modules, but only need to change the value of the directives managed in php.ini - you should simply copy the already assembled executable file php-SAPI to the site and perform the necessary actions with .htaccess:
/usr/local/bin/php-cgior
/usr/local/bin/phpdepending on the type of SAPI interface used.
If the set values of the directives in our INI files match the desired ones, you do not need to copy the INI file. In particular, such actions are performed when it is necessary to increase the memory_limit value for PHP. If you plan to change the directives in php-SAPI.ini — it should be copied, similar to the method described above.
ls /usr/local/etc/php.ini | awk '{print $1}' | xargs grep memory_limit
/usr/local/etc/php.ini: memory_limit = 32M
Pay special attention to the fact that if, as a result of adding your directive, you received an error or did not get the desired result, then there is a possibility that configuring the corresponding parameter is simply not available at this level. If so, try to build your own PHP, but first, please check with our technical support whether you really need your own PHP in this situation.
