How to correctly use PHP ini_set function_PHP tutorial

In the PHP configuration function, there is a function that sets the values ​​of certain variables in php.ini. It is the PHP ini_set function we are going to introduce to you today.

• The ini_set function is to set the value in the option. It takes effect after the function is executed. When the script ends, this setting also becomes invalid. Not all options can be set by the function. The specific values ​​that can be set can be viewed in the manual for a list.

  means that you can set the option value in php.ini. For example, if the display_error option is turned off, but you want to display the error message in the program to facilitate your debugging of the program, then you can use the PHP ini_set function:

  <ol class="dp-xml"><li class="alt"><span><span>ini_set(”display_errors<br>”, “On”); </span></span></li></ol>

  Then the program on your page will display error information, and you can also use error_reporting to set the level of error information displayed.
  If you need to increase the script execution time, you can set:

  <ol class="dp-xml"><li class="alt"><span><span>ini_set(”max_execution<br>_time”, “180″); </span></span></li></ol>

  Then the script execution time will be changed from the default 30 seconds to 180 seconds. Of course, you can also Use set_time_limit() to set.

  In fact, it is very good if you combine the PHP ini_set function with ini_get. For example, if you want to add your own include file path to the configuration file, but do you have permission to change php.ini, then you can combine two functions:

  <ol class="dp-xml"><li class="alt"><span><span>ini_set(’include_path’<br>,ini_get(’include_path’).<br>’:/your_include_dir:’);  </span></span></li></ol>
