Delete all images from folder except a original image in php

Question

I want delete all images from 'Logo' folder except an original image.

eg.

demo.jpg - original image

demo_50.jpg, demo_100.jpg, demo_150.jpg - other images.

Now i want to delete all images except demo.jpg using php

Answer 1

You can maintain a list of file which you do not want to delete in a directory.

$dir = 'direcotry';
$keepFiles = array('demo.jpg');

foreach( glob("$dir/*") as $file ) {
    if( !in_array(basename($file), $keepFiles) )
        unlink($file);
}

Another solution to this is,

1.Move that original file from current directory say X to some other directory say Y

2.Remove the complete directory X

3.Now move back that original file from Y to X

Answer 2

use unlink :

 if( !in_array($file, $original) )//$file is total file in the directory
        unlink($file);
