ini_set How to set php error message?

PHP uses ini_set() to set the display error message and execution time

PHP's 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.

It is to be able to 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 you to debug the program, then you can use the PHP ini_set function:

ini_set("display_errors", "On");

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:

ini_set("max_execution_time",  "180");

Then the script execution time will change from the default 30 seconds to 180 seconds. Of course, you can also use set_time_limit() set up.

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 in the configuration file, but do you have permission to change php.ini, then you can combine two functions:

ini_set('include_path',  ini_get('include_path') . ':/your_include_dir:');
