PHP Check Remote File

In this tutorial we we will check whether a file exist or not remotely using PHP

$filepath = "http://img.metblogs.com/lahore/files/2008/12/jinnah.jpg";
$isFileExists = file_get_contents($filepath,null,null,-1,1) ? true : false ;

if($isFileExists){
     echo "File Exists!";
}else{
     echo "File Does Not Exists";
}

what we do here is we use simple file_get_contents function just limiting its offset to -1 and maxlen or the amount of data to be read to 1 and check if the read is successful or not.
