Methods to modify the size limit of uploaded files in PHP

1. General file upload, unless the file is very small. Like a 5M file, it may take more than a minute to upload.

But in php, the default maximum execution time of the page is 30 seconds. That is to say, if it exceeds 30 seconds, the script will stop executing.

This leads to the situation that the webpage cannot be opened. At this time we You can modify max_execution_time

Look for

max_execution_time

in php.ini. The default is 30 seconds. Change it to

max_execution_time = 0

0 to indicate no limit

2. Modify post_max_size Sets the maximum size allowed for POST data. This setting also affects file uploads.

The default post_max_size of php is 2M. If the POST data size is larger than post_max_size, $_POST and $_FILES superglobals will be empty.

Find post_max_size. Change to

post_max_size = 150M

3. Many people will change the second step. But when uploading files, the maximum size is still 8M.

Why? We also need to change a parameter upload_max_filesize to indicate the maximum size of the uploaded file.

Look for upload_max_filesize, the default is 8M and change it to

upload_max_filesize = 100M

In addition, it should be noted that post_max_size is better than upload_max_filesize.

When phpcmsv9 uses swfupload to upload a large attachment in an iis7 environment, it prompts a server i/0 error

I initially thought that I only changed the value of the php.ini file to control the size of the uploaded file. It works, but after passing it on, an error message appears!

After that, I searched all kinds of ways to find the answer, and today I finally solved it. . . .

The solution is as follows:

1). Open the IIS manager and find the site of your website. Stop first. Then double-click "Request Filtering" in IIS to open it.

2). Click "Edit Function Settings" on the right to open the "Edit Request Filtering Settings" dialog box. The maximum allowed capacity length is "30000000" by default, 30M. Just modify it to the size you need. Then start IIS.
