php readfile modify file upload size settings

Use PHP ZipArchive to download small compressed packages. Today, I encountered a 404 error of over 150M. The first thing I thought of is that the file size exceeded the default settings of PHP. There are two ways to modify it:

：memory_limit

memory_limit sets memory limits. If you use readfile() to read the file, it will be related to this. Just modify this value and save it and restart php-fpm.

php download file size setting PHP

memory_limit = 128M

Last remember: service php-fpm restart

ini_set

The value used by PHP ini_set takes effect when the function is executed, so we can directly use it to modify the memory execution size. If some friends use virtual space, this function is a savior.

PHP Setting Value PHP

ini_set('memory_limit', '512M');

Complete example:

PHP

set_time_limit(0);
ini_set('memory_limit', '512M');
header("Cache-Control: public");
header("Content-Description: File Transfer");
header('Content-disposition: attachment; filename=' . basename($zipfile));
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($zipfile));
ob_clean();
flush();
@readfile($zipfile);
unlink($zipfile);
