Zipar directory with PHP

Zipar directory with PHP

I have a code that compacts file and directory. The problem is that it compresses the files and directories that are in the root, but the subdirectories they are not compressed, for example I have these directories:

Folder/, folder/file.php, folder / other / folder2, file1.php

It only compacts folder / and file1.php ...

It should compress the file.php, other/, Folder 2 /

Code:

<?php

function Show_files($local){

    $zip = new ZipArchive();

    if($zip->open('compact.zip', ZIPARCHIVE::CREATE) == TRUE){

    $open = opendir($local);

    while($folder = readdir($open)){

        if(is_dir($local.$folder) && $folder != '.' && $folder != '..'){

            echo $local.$folder.'<br>';

            $zip->addEmptyDir($folder);

            Show_files($local.$folder.'/');

        }elseif(is_file($local.$folder) && $folder != '.' && $folder != '..'){

            $zip->addFile($local.$folder, $folder);

                echo $local.$folder.'<br>';
        }
    }
}

}
    $raiz = str_replace("\\", "/", getcwd())."/";
    Show_files($raiz);

?>

What is happening is that you are rewriting the file because it is a recursive function, so the instance $zip it is created every time it goes through the recursive function call. To work out create out instance $zip and pass as function parameter.

Example with function:

<?php
    function Compact($zip, $cwd) {
        $open = opendir($cwd);
        while($folder = readdir($open))
        {
            if ($folder != '.' && $folder != '..'){
                if (is_dir($cwd.'/'.$folder))
                {
                    $dir = str_replace('./', '',($cwd.'/'.$folder));
                    $zip->addEmptyDir($dir);
                    Compactar($zip, $dir);
                }
                elseif (is_file($cwd.'/'.$folder))
                {
                    $arq = str_replace('./', '',$cwd.'/'.$folder);                  
                    $zip->addFile($arq);                                        
                }
            }
        }
    }

    $zip = new ZipArchive();
    if ($zip->open("arquivoFAfa.zip", ZIPARCHIVE::CREATE) === true){
        Compact($zip, ".");
    }
    $zip->close();

Example with class extending ZipArchive

<?php
    class Zipper extends ZipArchive 
    {
        public function Compact($cwd) {
            $open = opendir($cwd);
            while($folder = readdir($open))
            {
                if ($folder != '.' && $folder != '..')
                {
                    if (is_dir($cwd.'/'.$folder))
                    {
                        $dir = str_replace('./', '',($cwd.'/'.$folder));
                        $this->addEmptyDir($dir);
                        $this->Compact($dir);
                    } 
                    elseif (is_file($cwd.'/'.$folder))
                    {
                        $arq = str_replace('./', '',$cwd.'/'.$folder);                  
                        $this->addFile($arq);                   
                    }
                }
            }
        }
    }

    $zip = new Zipper();
    if ($zip->open("arquivoFAClassAbc.zip", ZIPARCHIVE::CREATE) === true){
        $zip->Compact(".");
    }
    $zip->close();

Tip: use the second option, because you will not have this instance problem, although the first is only to create the instance outside as reported at the beginning of the response.
