How to create compressed file using PHP with destination directory? - php

Question

I found the script below from previous posts to create a ZIP file using PHP.
This script lets you create a zip file, but it doesn't let you create it in any directory you want. This is the original code.
<?php
// Config Vars
$sourcefolder = "uploads/output" ; // Default: "./"
$zipfilename = "myarchive.zip"; // Default: "myarchive.zip"
$timeout = 5000 ; // Default: 5000
// instantate an iterator (before creating the zip archive, just
// in case the zip file is created inside the source folder)
// and traverse the directory to get the file list.
$dirlist = new RecursiveDirectoryIterator($sourcefolder);
$filelist = new RecursiveIteratorIterator($dirlist);
// set script timeout value
ini_set('max_execution_time', $timeout);
// instantate object
$zip = new ZipArchive();
// create and open the archive
if ($zip->open("$zipfilename", ZipArchive::CREATE) !== TRUE) {
die ("Could not open archive");
}
// add each file in the file list to the archive
foreach ($filelist as $key=>$value) {
$zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key");
}
// close the archive
$zip->close();
echo "<br>Archive ". $zipfilename . " created successfully - ";
// And provide download link ?>
Download <?php echo $zipfilename?>
I tried amending the code to be able to decide the desitnation of the script as I found no solution after spending a couple of hours on the internet. Some solutions suggested where to change $zipfilename = "myarchive.zip"; to $zipfilename = "uploads/output/myarchive.zip"; but in the URL to download link I want to appear as: Archive myarchive.zip created successfully - Download myarchive.zip not as Archive uploads/output/myarchive.zip created successfully - Download myarchive.zip
Therefore I tried this code, but it didn't work for me. I don't know what I did wrong.
<?php
// Config Vars
$sourcefolder = "uploads/output" ; // Default: "./"
$destfolder = "uploads/output/"; // Default: "myarchive.zip"
$zipfilename = "myarchive.zip"; // Default: "myarchive.zip"
$timeout = 5000 ; // Default: 5000
// instantate an iterator (before creating the zip archive, just
// in case the zip file is created inside the source folder)
// and traverse the directory to get the file list.
$dirlist = new RecursiveDirectoryIterator($sourcefolder);
$filelist = new RecursiveIteratorIterator($dirlist);
// set script timeout value
ini_set('max_execution_time', $timeout);
// instantate object
$zip = new ZipArchive();
// create and open the archive
if ($zip->open(''.$destfolder.''.$zipfilename.'', ZipArchive::CREATE) !== TRUE) {
die ("Could not open archive");
}
// add each file in the file list to the archive
foreach ($filelist as $key=>$value) {
$zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key");
}
// close the archive
$zip->close();
echo "<br>Archive ". $zipfilename . " created successfully - ";
// And provide download link ?>
Download <?php echo $zipfilename?>

Example static method to create zip archive:
//...
public static function zip($source, $destination)
{
if (!extension_loaded('zip') || !file_exists($source)) {
throw new \Exception('zip not loaded');
}
$zip = new \ZipArchive();
if ($zip->open($destination, \ZIPARCHIVE::CREATE) === false) {
return false;
}
if (is_dir($source) === true) {
$files = new \RecursiveIteratorIterator(
new \RecursiveDirectoryIterator($source),
\RecursiveIteratorIterator::SELF_FIRST
);
foreach ($files as $file) {
if (in_array(substr($file, strrpos($file, DIRECTORY_SEPARATOR) + 1), array('.', '..'))) {
continue;
}
$file = realpath($file);
if (is_dir($file) === true) {
$zip->addEmptyDir(str_replace($source . DIRECTORY_SEPARATOR, '', $file . DIRECTORY_SEPARATOR));
} else {
if (is_file($file) === true) {
$zip->addFromString(
str_replace($source . DIRECTORY_SEPARATOR, '', $file),
file_get_contents($file)
);
}
}
}
} else {
if (is_file($source) === true) {
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close();
}
// ...
