How can the upload_max_filesize limit in PHP be adjusted for larger file uploads?

To adjust the upload_max_filesize limit in PHP for larger file uploads, you can modify the php.ini file by increasing the value of the upload_max_filesize directive. Alternatively, you can also adjust this limit programmatically using the ini_set function within your PHP script.
