ini_set to update settings of php.ini file

We can't change all the configured settings of php.ini file. PHP will permit to change some data by using ini_set function. We will verify after changing the configured data by using ini_get function. Here is the code. Please note the outputs shown here will change based on your server settings when you try.

echo ini_get('mysql.connect_timeout');  // OUTPUT 60
ini_set('mysql.connect_timeout',100);
echo "<br>";
echo ini_get('mysql.connect_timeout');  // output 100

We can change some of the configuration options by using ini_set() during the script execution. We can’t change permanently the setting by using ini_set(). Values will return to original value once the script execution is over.
