php check file name exist, rename the file

Question

How do I check if file name exists, rename the file?

for example, I upload a image 1086_002.jpg if the file exists, rename the file as 1086_0021.

I hope this helps

$fullPath = "images/1086_002.jpg" ;
$fileInfo = pathinfo($fullPath);
list($prifix, $surfix) = explode("_",$fileInfo['filename']);
$x = intval($surfix);
$newFile = $fileInfo['dirname'] . DIRECTORY_SEPARATOR . $prifix. "_" . str_pad($x, 2,"0",STR_PAD_LEFT)  . $fileInfo['extension'];
while(file_exists($newFile)) {
    $x++;
    $newFile = $fileInfo['dirname'] . DIRECTORY_SEPARATOR . $prifix. "_" . str_pad($x, 2,"0",STR_PAD_LEFT)  . $fileInfo['extension'];
}

file_put_contents($newFile, file_get_contents($_POST['upload']));

I hope this Helps
