The solution that php ini_set does not work: 1, modify the configuration such as post_max_size with ".htaccess" file; 2, configure "AllowOverride All" in "httpd.conf".

Operating environment of this article: Windows7 system, PHP7.1 version, Dell G3 computer

Situations where ini_set doesn't work

Ini_set-sets the value for a configuration option

1. Not all valid options for php.ini can be set with ini_set

two。 Not available when an option can be set, but when the server has a virtual host.

Php ini_set doesn't work?

In PHP configuration, post_max_size,upload_max_filesize cannot be modified with the ini_set () method.

The correct thing to do is to use the .htaccess file:

Php_value upload_max_filesize 1024M php_value post_max_size 1024M

For the .htaccess file to take effect, you need to configure the site in httpd.conf: AllowOverride All

Reason: the modifiable scope of upload_max_filesize is PHP_INI_PERDIR, which can be modified in php.ini,httpd.conf or .htaccess files, but not with ini_set ().

Knowledge points:

Constant value meaning

PHP_INI_USER, 1, configuration options can be set in the user's PHP script or Windows registry

PHP_INI_PERDIR, 2, configuration options can be configured in php.ini, .htaccess or httpd.conf

PHP_INI_SYSTEM, 4, configuration options can be configured in php.ini or httpd.conf

PHP_INI_ALL, 7, configuration options can be set everywhere

PS:

Magic_quotes_gpc is obtained with get_magic_quotes_gpc () and cannot be modified with set_magic_quotes_gpc because there is no such function.

Magic_quotes_runtime can be set with set_magic_quotes_runtime ()
