The solution to the ineffectiveness of ini_set in PHP

This article will explain in detail the solution to the ineffectiveness of ini_set in PHP. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The solution that PHP ini_set does not work: 1, modify the htaccess file; 2, configure "AllowOverride All" in httpd.conf.

This article operating environment: Windows7 system, PHP7.1 version, Dell G3 computer.

The reason why PHP ini_set () is invalid:

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:

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 ()
