PHP8.1 released: supports inline editing of php.ini files

PHP is a widely used server-side scripting language for developing web applications. Its latest version, PHP8.1, brings many new features and improvements, one of the eye-catching features is support for inline editing of php.ini files. This new feature allows developers to dynamically modify the configuration items of the php.ini file at runtime without restarting the web server, greatly improving development efficiency.

In the past, to modify an option in the php.ini configuration file, we usually needed to find and open the corresponding php.ini file, then manually modify the values in it, and finally restart the web server to make the configuration take effect. . This process is cumbersome and time-consuming, and will also interrupt running web services and bring inconvenience to the development process. In PHP8.1, we can use the new API directly in the code to modify the php.ini file, which will take effect immediately without restarting the server.

To use the php.ini inline editing function, we need to first ensure that the correct configuration is made in the php.ini file. Find the following line of code:

; Enable php.ini inline editing ; (注意:这里是英文分号，意味着该行为注释) ;zend_config_inline_edit=On

Uncomment and set the value ofzend_config_inline_edittoOn, save and exit the php.ini file. Then we can use theini_set()function in the code to modify the options in the php.ini file.

The following is an example:

The above code will print out the value of the currently setdisplay_errorsoption without restarting the web server. This allows developers to modify options in the php.ini file at any time while debugging code without interrupting the web service.

In addition, the php.ini inline editing function also supports dynamic modification of other configuration items, such aserror_reporting,memory_limit, etc. Developers can use theini_set()function in the code to make configuration modifications according to actual needs.

However, it should be noted that the php.ini inline editing function is limited to modifying the option values of the php.ini file at runtime, and does not modify the php.ini file itself. This means that after restarting the web server, the changes will be invalidated and reverted to the default values in the php.ini file.

To sum up, the php.ini inline editing function of PHP8.1 provides developers with a more convenient and flexible way to modify php.ini configuration items. By using theini_set()function in the code, we can adjust the value of the configuration item at any time without restarting the web server, which greatly improves development efficiency. The introduction of this feature will further promote the development and application of PHP language in the field of Web development.
