upload_max_filesize = 2M
memory_limit = 8M
max_input_time = 60

Change to:
post_max_size = 750M
max_execution_time = 5000

memory_limit = 1000M
max_input_time = 5000

<IfModule mod_php5.c>
php_value post_max_size 200M
php_value max_execution_time 259200
php_value upload_max_filesize 200M
php_value memory_limit 300M
php_value max_input_time 259200
</IfModule>

If you don't have access of your php.ini or dont use htaccess file, you can use ini_set in your php file:
For example - ini_set('max_execution_time', 5000);

What is .htaccess file?
".htaccess is a configuration file for use on web servers running the Apache Web Server software.

When a .htaccess file is placed in a directory which is in turn 'loaded via the Apache Web Server', then the .htaccess file is detected and executed by the Apache Web Server software.

These .htaccess files can be used to alter the configuration of the Apache Web Server software to enable/disable additional functionality and features that the Apache Web Server software has to offer."

SetEnvIf Origin "http(s)?://(www\.)?(yourdomainname.com)$" AccessControlAllowOrigin=$0
Header set Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin

Header set Access-Control-Allow-Credentials true
