How to upload large files above 500MB in PHP?
Large files can be uploaded using PHP in two ways. Both of them are discussed below −
- By changing the upload_max_filesize limit in the php.ini file.
- By implementing file chunk upload, that splits the upload into smaller pieces an assembling these pieces when the upload is completed.
The php.ini file can be updated as shown below −
upload_max_filesize = 50M post_max_size = 50M max_input_time = 300 max_execution_time = 300
This should be avoided since it would change the settings of the server and other projects too.
Updating the htacess file
php_value upload_max_filesize 50M php_value post_max_size 50M php_value max_input_time 300 php_value max_execution_time 300
Changing the inline setting −
<?php
// changing the upload limits
ini_set('upload_max_filesize', '50M');
ini_set('post_max_size', '50M');
ini_set('max_input_time', 300);
ini_set('max_execution_time', 300);
// destination folder is set
$source = $_FILES["file-upload"]["tmp_name"];
$destination = $_FILES["file-upload"]["name"];
// uploaded folder is moved to the destination
move_uploaded_file($source, $destination);
?>Chunking
In this process, a large file is split into smaller parts and then uploaded. The ‘Plupload’ library can be downloaded and used.
<?php
// the response function
function verbose($ok=1,$info=""){
// failure to upload throws 400 error
if ($ok==0) { http_response_code(400); }
die(json_encode(["ok"=>$ok, "info"=>$info]));
}
// invalid upload
if (empty($_FILES) || $_FILES['file']['error']) {
verbose(0, "Failed to move uploaded file.");
}
// upload destination
$filePath = __DIR__ . DIRECTORY_SEPARATOR . "uploads";
if (!file_exists($filePath)) {
if (!mkdir($filePath, 0777, true)) {
verbose(0, "Failed to create $filePath");
}
}
$fileName = isset($_REQUEST["name"]) ? $_REQUEST["name"] : $_FILES["file"]["name"];
$filePath = $filePath . DIRECTORY_SEPARATOR . $fileName;
// dealing with the chunks
$chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0;
$chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 0;
$out = @fopen("{$filePath}.part", $chunk == 0 ? "wb" : "ab");
if ($out) {
$in = @fopen($_FILES['file']['tmp_name'], "rb");
if ($in) {
while ($buff = fread($in, 4096)) { fwrite($out, $buff); }
} else {
verbose(0, "Failed to open input stream");
}
@fclose($in);
@fclose($out);
@unlink($_FILES['file']['tmp_name']);
} else {
verbose(0, "Failed to open output stream");
}
// check if file was uploaded
if (!$chunks || $chunk == $chunks - 1) {
rename("{$filePath}.part", $filePath);
}
verbose(1, "Upload OK");
?>When a file whose size is greater than 500 MB is tried to be uploaded, it successfully gets uploaded.
