How can i unlink file for removal in symfony2

I a using this code for image removal when i delete the entity

  /**
     * @ORM\PostRemove()
     */
    public function removeUpload()
    {
        if ($this->filenameForRemove)
        {
            unlink ( $this->filenameForRemove );
        }
    }

But the problem is if i don't have the image there then it throws exception like this

Warning: unlink(/home/site/../../../../uploads/50343885699c5.jpeg) [<a href='function.unlink'>function.unlink</a>]: No such file or directory i

Is there any way that if file is not there or directory is not there it should skip this step and still deletes the entity

Symfony has introduced the The Filesystem Component. You can check the docs here. It says: The Filesystem component provides basic utilities for the filesystem.

For example you can check if the file path/directory exists before deleting your file like this:

use Symfony\Component\Filesystem\Filesystem;


$filesystem = new Filesystem();
$oldFilePath = '/path/to/directory/activity.log'

if($filesystem->exists($oldFilePath)){
    $filesystem->remove($oldFilePath); //same as unlink($oldFilePath) in php
}

You can use file_exists to make sure the file actually exists and is_writable to make sure you have permission to remove it.

if ($this->filenameForRemove)
{
    if (file_exists($this->filenameForRemove) &&
        is_writable($this->filenameForRemove))
    {
        unlink ( $this->filenameForRemove );
    }
}
