Answer 1

Create a zip folder in PHP.

Zip create method

   public function zip_creation($source, $destination){
    $dir = opendir($source);
    $result = ($dir === false ? false : true);

    if ($result !== false) {

        
        $rootPath = realpath($source);
         
        // Initialize archive object
        $zip = new ZipArchive();
        $zipfilename = $destination.".zip";
        $zip->open($zipfilename, ZipArchive::CREATE | ZipArchive::OVERWRITE );
         
        // Create recursive directory iterator
        /** @var SplFileInfo[] $files */
        $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($rootPath), RecursiveIteratorIterator::LEAVES_ONLY);
         
        foreach ($files as $name => $file)
        {
            // Skip directories (they would be added automatically)
            if (!$file->isDir())
            {
                // Get real and relative path for current file
                $filePath = $file->getRealPath();
                $relativePath = substr($filePath, strlen($rootPath) + 1);
         
                // Add current file to archive
                $zip->addFile($filePath, $relativePath);
            }
        }
         
        // Zip archive will be created only after closing object
        $zip->close();
        
        return TRUE;
    } else {
        return FALSE;
    }


}

Call the zip method

$source = $source_directory;
$destination = $destination_directory;
$zipcreation = $this->zip_creation($source, $destination);

I did some small improvement in the script.

  <?php
    $directory = "./";
    //create zip object
    $zip = new ZipArchive();
    $zip_name = time().".zip";
    $zip->open($zip_name,  ZipArchive::CREATE);
    $files = new RecursiveIteratorIterator(
        new RecursiveDirectoryIterator($directory),
        RecursiveIteratorIterator::LEAVES_ONLY
    );
    foreach ($files as $file) {
        $path = $file->getRealPath();
        //check file permission
        if(fileperms($path)!="16895"){
            $zip->addFromString(basename($path),  file_get_contents($path)) ;
            echo "<span style='color:green;'>{$path} is added to zip file.<br /></span> " ;
        }
        else{
            echo"<span style='color:red;'>{$path} location could not be added to zip<br /></span>";
        }
    }
    $zip->close();
    ?>

Try this:

$zip = new ZipArchive;
$zip->open('myzip.zip', ZipArchive::CREATE);
foreach (glob("target_folder/*") as $file) {
    $zip->addFile($file);
    if ($file != 'target_folder/important.txt') unlink($file);
}
$zip->close();

This will not zip recursively though.
