Removing directory and its contents in php

[thara]

I am trying to remove folders and its files and sub folders using php.

This is how I tried it.

    $dir      = "../../images/$category_id/$delId";
    $it      = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
    $files = new RecursiveIteratorIterator($it, RecursiveIteratorIterator::CHILD_FIRST);
    foreach($files as $file) {
        if ($file->isDir()){
            rmdir($file->getRealPath());
        } else {
            unlink($file->getRealPath());
        }
    }
    rmdir($dir);

This is working on php 5.5+, but is doesn't work in php 5.2.17.

 

This is the error can I get when it running on php 5.2.17

 

<br /> <b>Fatal error</b>: Undefined class constant 'SKIP_DOTS' in <b>/home2/public_html/admin /includes/process_edit.php</b> on line <b>124</b><br />

 

Can anybody tell me how I get it to work on 5.2 also.
Thank you.

Nobody should be using php 5.2, at a minimum some hosts using 5.4, really should be 5.5+ and php7 is here.

FYI: Php 5.2 is over one hundred versions behind.
