php socket function

Hi all, need some help about socket functions. I try tu use socket function. This is my script: if (($sock = socket(AF_INET, SOCK_STREAM, 0)) < 0) { echo "socket() a echoué - raison : " . strerror($sock) . "\n"; } And this is the error I always get : Fatal error: Call to undefined function: socket() in d:\myscript.php on line 175 I'm using PHP with WIN NT. The error is the same with PHP Version 4.0.5-dev , or PHP Version 4.0.4. I've installed PHP from binary code, not with re-compiling source. First question : is socket function installed on php version for windows ? Second : if yes, where is the problem..... Thank you for your help, François Tissandié.
