PHP - Parse And Explode A Url

$hash = file_get_contents("url");
the source code has this

'<input type="hidden" name="hash" value="Mr607qtwQQuX">'

how could I get preg_match or explode to parse out just the hash Mr607qtwQQuX?

thanks

If I explode a string well using a substring when I implode that substring is now missing.

for example.
Code: [Select]
$exploded = explode("[MAC]",$data);

$data = implode($exploded);
Now [MAC] would be missing in the $data string. any way to get around this?

Hello I have one problem with fwrite() I have one script to get width and height from javascript and echo it with PHP.
echo "Screen width is: ". $_GET['width'] ."<br />\n";
echo "Screen height is: ". $_GET['height'] ."<br />\n";
It works but i want to store the result in a file
fwrite($info,"Height: $_GET['height'] <br />");
But then I get error Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING
////////////////////////
it would be even better if I don't have to print the values but directly store them in $iinfo
sorry if something similar was soved but those examples were different or i was unable to transform it to solve my problem
