What is the file size limit for uploading multiple files simultaneously in PHP?

When uploading multiple files simultaneously in PHP, there is a file size limit set by the server configuration. This limit is typically controlled by the "upload_max_filesize" and "post_max_size" directives in the php.ini file. To increase the file size limit for uploading multiple files, you will need to adjust these directives to accommodate the desired file size.

// Adjust the file size limit for uploading multiple files in PHP
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '25M');
