PHP upload size limit modification

Uploading is a very common and important point in PHP development, and the size of PHP upload is limited. In order to better improve the upload speed of PHP, we need to modify the upload size limit, okay! Let’s take a look at how to modify PHP upload restrictions!

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 The longest page execution time is 30 seconds. That is to say, if it exceeds 30 seconds, the script will stop executing.
   This will lead to the situation that the web page cannot be opened.

At this time we can Modify max_execution_time
Look for

max_execution_time

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

max_execution_time = 0

0 to indicate no limit

2. Modify post_max_size to set 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.
