upload_max_filesize

upload_max_filesize is the maximum size of an uploaded file.

For example, upload_max_filesize = 3M : it means you can upload the maximum size of a file up to 3MB.

You can change this value by adding the code to php.ini file (usually, it’s located in the root directory):

upload_max_filesize = 3M

Just change 3 with your value.
