How to modify the upload size limit of php files

//Find

　Options FollowSymLinks
　AllowOverride None

//Change to
< ;Directory />
　Options FollowSymLinks
　AllowOverride All

//That’s it

Create a new .htaccess file in the directory. Windows does not allow this by default. If you do, you can create a new one under Dreamweaver's file management, and it won't work anymore.

Write in .htaccess

php_value post_max_size 12m
php_value upload_max_filesize 12m
php_value max_execution_time 120
php_value max_input_time 240

and it’s OK

Additional explanation: The method of using ini_set("post_max_size", "80M"); will not work.

PHP_INI_PERDIR is an intra-domain directive that can only be modified in the php.ini, httpd.conf or .htaccess file, so it will not work. php_value name value Sets the value of the specified command. Can only be used with directives of type PHP_INI_ALL and PHP_INI_PERDIR. To clear the last set value, set the value to none .

Note: Do not use php_value to set boolean values. php_flag (see below) should be used instead. php_flag name on|off Configuration directive used to set the type of boolean value. Can only be used with directives of type PHP_INI_ALL and PHP_INI_PERDIR. php_admin_value name value

Set the value of the specified command. Cannot be used in .htaccess files. Any value set in php_admin_value cannot be overridden by directives in .htaccess or virtualhost. To clear the last set value, set the value to none . php_admin_flag name on|off
