can't echo in real time under a foreach loop

[dodgerfan]

I wrote a short script that takes a list of keywords and does a Google search to find how often they are used in the title of a page.  However, I cannot get it to echo the results in real time.  On one server I use it works fine.  On the other it runs the entire list and then outputs everything in the end.  The problem is sometimes this takes several minutes and therefore it times out after not receiving a response.

 

Any suggestions?

 

Thanks in advance.

 

<?php 

$file = file('words.txt'); 

$results = ''; 
foreach ($file as $line) { 
    $data     = file_get_contents("http://www.google.com/search?hl=en&q=allintitle%3A%22" . urlencode($line) . "%22&btnG=Google+Search"); 
    preg_match('/of about <b>([0-9,]*)?<\/b>/si', $data, $number); 
    $results .= $line . ";" . $number[1]; 
    echo $results . "</br>"; 
    $results = "";
    sleep(2);
} 

?>

have you tried running it through a

WHILE (!feof($file))

instead?

No I haven't.  My PHP knowledge is extremely basic.  Can you tell me what it should be and I'll give it a shot.

 

Thanks.

Thanks for the suggestion.  I read elsewhere to try using the flush() command after each echo to force the info to the browser.  Seems to work.
