Make Zip Archive of a directory (including all files in it recursively) in PHP

ZipDirectory.php

<?php

    public function __construct(
        private string $sourcePath,

                return $this->outputPath;
            }

            throw new \RuntimeException("Failed to make zip file at ({$this->outputPath}).");

How to use?

$targetDir = '/path/to/TargetDir';
$zipPath = (new ZipDirectory($targetDir))->make();
// $zipPath should be: /path/to/TargetDir.zip

$outputPath = '/path/to/another/location/output.zip';
$zipPath = (new ZipDirectory($targetDir, $outputPath))->make();
// $zipPath should be: /path/to/another/location/output.zip

$zipPath = (new ZipDirectory($targetDir))->make(true);
// $zipPath should be: /path/to/TargetDir.zip
// And "/path/to/TargetDir" directory should be removed
