What is the PHP upload limit on Linux hosting accounts?
By default, PHP limits scripts uploading files to 32 MB. To change the limitation, edit or add the following values in your PHP initialization file (more info):
post_max_size = 50M
upload_max_filesize = 50M
The above settings change your PHP upload limit, allowing you to upload files up to 50MB in size.
The maximum upload value that you can specify for upload_max_size and post_max_size is 64MB for Classic Hosting and 128MB for Web Hosting. For more information, see What type of hosting account do I have?
Depending on the size of the file and upload speed, the PHP script used for uploading could time out prior to completion.
Changes to your PHP initialization file doesn't take effect immediately. However, you can get the updated file to take effect by following the instructions in Why isn't my PHP initialization file taking effect?
