How can I modify the limit on the size of PHP file uploads?

Method 1: Modify the related parameters of php. ini: file_uploadson; enable or disable file upload over HTTP. The default value is ON, which is to open upload_tmp_dir. The file is uploaded to the place where the temporary file is stored ON the server. If it is not specified, the default Temporary Folder will be used. Upload_max_filesize2m; wangwen business, that is, allow

Method 1: Modify the related parameters of php. ini: file_uploads = on; whether to allow file upload through HTTP. The default value is ON, which is to open upload_tmp_dir.

Method 1: Modify php. ini
Description of related parameters:
File_uploads = on; whether to allow file upload over HTTP. ON is enabled by default.
Upload_tmp_dir; upload the file to the place where the temporary file is stored on the server. If it is not specified, the default Temporary Folder will be used.
Upload_max_filesize = 2 m; wangwen business, that is, the maximum file size allowed to be uploaded. The default value is 2 MB.
Post_max_size = 8 m; the maximum value that can be received by posting a form to PHP, including all values in the form. The default value is 8 Mb.
Max_execution_time = 30; maximum time (in seconds) for running each PHP page. The default value is 30 seconds.
Max_input_time = 60; maximum time required for receiving data on each PHP page. The default value is 60 seconds.
Memory_limit = 128 m; maximum memory size consumed by each PHP page. The default value is 128 M. If you think it is small, you can set it to bigger. 128 is enough.
Max_execution_time= 600
Max_input_time= 600
Upload_max_filesize = 32 m
Post_max_size = 32 m

After modifying the preceding parameters, you can upload a large volume of files as permitted by the network.

Method 2: Use the. htaccess File
This method does not require direct modification of php. ini, which is applicable to virtual hosts.
Configure Apache to support. htaccess

The Code is as follows:

// Find

Options FollowSymLinks
AllowOverride None

// Change

Options FollowSymLinks
AllowOverride All

// You can.

Create a new. htaccess file in the directory. This is not allowed in windows by default. You can create a file under Dreamweaver file management.

Write in. htaccess

The Code is as follows:

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

OK.

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

The modifiable range of post_max_size is PHP_INI_PERDIR.
PHP_INI_PERDIR is a domain command that can only be modified in the php. ini, httpd. conf, or. htaccess file, so it does not work.
Php_value name value
Set the value of the specified command. Only commands of the PHP_INI_ALL and PHP_INI_PERDIR types can be used. To clear the previous set value, set the value to none.

Note: Do not use php_value to set a Boolean value. Php_flag should be used (see below.
Php_flag name on | off
The configuration command used to set the boolean type. Only commands of the PHP_INI_ALL and PHP_INI_PERDIR types can be used.
Php_admin_value name value

Set the value of the specified command. It cannot be used in the. htaccess file. Any value set in php_admin_value cannot be overwritten by commands in. htaccess or virtualhost. To clear the previous set value, set the value to none.
Php_admin_flag name on | off
