As a PHP developer, we often need to implement functionality to download files. But sometimes it needs to implement large files download in MB, GBs and that create many issues. So here I have created a simple PHP script to download large files .
Also, read:

- Convert XML into Associative Array in PHP
- Converting an Array to JSON in PHP
- Converting JSON to Array or Object in PHP
This script helps you download files in PHP, capable of downloading files in MB and GBs with any issue.
<?php function downloadFiles($filePath) { if(!empty($filePath)) { $fileInfo = pathinfo($filePath); $fileName = $fileInfo['basename']; $fileExtnesion = $fileInfo['extension']; $default_contentType = "application/octet-stream"; $content_types_list = mimeTypes(); if (array_key_exists($fileExtnesion, $content_types_list)) { $contentType = $content_types_list[$fileExtnesion]; } else { $contentType = $default_contentType; } if(file_exists($filePath)) { $size = filesize($filePath); $offset = 0; $length = $size; if(isset($_SERVER['HTTP_RANGE'])) { preg_match('/bytes=(\d+)-(\d+)?/', $_SERVER['HTTP_RANGE'], $matches); $offset = intval($matches[1]); $length = intval($matches[2]) - $offset; $fhandle = fopen($filePath, 'r'); fseek($fhandle, $offset); $data = fread($fhandle, $length); fclose($fhandle); header('HTTP/1.1 206 Partial Content'); header('Content-Range: bytes ' . $offset . '-' . ($offset + $length) . '/' . $size); } //Heasers for download header("Content-Disposition: attachment;filename=".$fileName); header('Content-Type: '.$contentType); header("Accept-Ranges: bytes"); header("Pragma: public"); header("Expires: -1"); header("Cache-Control: no-cache"); header("Cache-Control: public, must-revalidate, post-check=0, pre-check=0"); header("Content-Length: ".filesize($filePath)); $chunksize = 8 * (1024 * 1024); //8MB (highest possible fread length) if ($size > $chunksize) { $handle = fopen($_FILES["file"]["tmp_name"], 'rb'); $buffer = ''; while (!feof($handle) && (connection_status() === CONNECTION_NORMAL)) { $buffer = fread($handle, $chunksize); print $buffer; ob_flush(); flush(); } if(connection_status() !== CONNECTION_NORMAL) { echo "Connection aborted"; } fclose($handle); } else { ob_clean(); flush(); readfile($filePath); } } else { echo 'File does not exist!'; } } else { echo 'There is no file to download!'; } } ?>
Here I have created a function mimeTypes() to get correct MIME type for download:
<?php function mimeTypes() { /* Just add any required MIME type if you are going to download something not listed here.*/ $mime_types = array("323" => "text/h323", "acx" =>

Now we will call downloadFiles() function and pass download file path to download files:
<?php /* You may need these ini settings too */ set_time_limit(0); ini_set('memory_limit', '512M'); /*set your download file path here. */ $filePath = "E:/MyFiles/Software/XYZ.rar"; /* calls download function */ downloadFiles($filePath); ?>
