PHP supports the following resource limits directives in php.ini file. To limit resources used by a PHP script edit the file php.ini. Note that this change will affect all websites and PHP scripts on the server.

To find the location of php.ini, you can use the phpinfo() PHP function to find it. Create file with following content:

<?php
phpinfo();
?>

Sample outputs:

To edit php.ini, type the following command:

[root@lifelinux ~]# vi /etc/usr/local/etc/php.ini

Set maximum execution time of each script:

max_execution_time = 30

Set maximum amount of time each script may spend parsing request data

max_input_time = 30

Set maximum amount of memory a script may consume

memory_limit = 64M

Set maximum size of POST data that PHP will accept

post_max_size = 8M

Set maximum allowed size for uploaded files

upload_max_filesize = 8M

Disable/Enable HTTP file uploads (Disallow uploading unless necessary)

Final, restart web server, example restart apache server, type the following command

[root@lifelinux ~]# /etc/init.d/httpd restart
