How to change PHP's upload file-size limit

For this example, we'll configure php.ini to allow uploads under 512M. Find and change the following settings: file_uploads = On ;enable file uploads upload_max_filesize = 512M ;upload size limit. To upload larger files, these two changes alone are not enough. You also need to raise the server's buffer limit and give scripts more time to run. post_max_size = 512M ;POST size limit max_execution_time = 1800 ; Maximum execution time of each script, in seconds max_input_time = 1800 ; Maximum amount of time each script may spend parsing request data memory_limit = 128M ; Maximum amount of memory a script may consume (128MB)
