Is This Possible? $filename fopen Question

[wxflint]

What I an wanting to do here is have the script email me when the user count reaches X number of listeners on my RR Scanner Feed.
Is This Possible?

<?php
    $filename = '<script language="JavaScript" src="http://api.radioreference.com/audio/listeners.php?feedId=10734"></script>'; 
    $fp = fopen( $filename,"r"); 
    if ($filename >= X) {
  //// ($email Me @ My Email Address Or Any Address I Add Here) ////
  exit();
}                       
    fclose( $fp ); 
    print "Online=$filename";   
?>

You'd have to store the file open count somewhere (file/database), but you would need a decrement too when sombody stops using it.

Thanks I see what you are saying I have found this code here but for the life of me I cant figure out how to get it to read the above mentioned

$filename = '<script language="JavaScript" src="http://api.radioreference.com/audio/listeners.php?feedId=10734"></script>';

and get it to write to a txt file.

<?php
    $filename = "PHPCounter.txt"; 
    $fp = fopen( $filename,"r");             
    $Old = fread($fp, 100);
    fclose( $fp );
    $Old = split ("=", $Old, 5);        
    $NewCount = $Old[1] + '1';        
    $New = "Online=$NewCount";        
    $fp = fopen( $filename,"w+");         
    if (flock($fp, 2)) { 
      fwrite($fp, $New, 100);
    }         
    fclose( $fp );

    print "Online=$NewCount";     
?>

What do you want with that script tag ?

What do you want with that script tag ?

What I am wanting is have the script email me when the user count reaches X number of listeners on my RR Scanner Feed.
So it would read the file

$filename = '<script language="JavaScript" src="http://api.radioreference.com/audio/listeners.php?feedId=10734"></script>';

and write it to a txt file and then email me when the listener count reaches X number if listeners.

That script is hosted by another party, and you want to read the number it returns in the document.write ? And based on that number send an email ?

pritaeas, Yes sir that is correct.

I think this should do it (can't test right now):

$filename = "http://api.radioreference.com/audio/listeners.php?feedId=10734";
$data = file_get_contents($filename);
preg_match('/document\.write\(\'(.*?)\'\);/i', $data, $result)
$listeners = $result[1];
echo $listeners;
