help to preg_match a variable please

Hi to all people looking in,

Im pretty new to PHP although i’ve learnt an awful lot in the last few days of playing around and researching.

So far what I have is an pipe email to php script set up (that works fine). I’ve got this from the web, which im using now:

[php]$fd = fopen(“php://stdin”, “r”);
$email = “”;
while (!feof($fd))
$email .= fread($fd,1024);

What i need to do is search the email that has been retrieved for a string using regex. I’ve tried using preg_match to do it but i believe due to the $email variable being empty i am not getting a match.

[php]preg_match(’/http/’, $email, $match);[/php]

I’ve also added to the end of my code:

[php]$fdw = fopen(“email.txt”, “w+”);
fwrite($fdw, $email);

which works fine, and saves the email to a text file. So i cant figure out why writing $email works but searching $email with preg_match doesnt.

Please if anybody could shed some light, I would be very grateful.

Thankyou very much!
