fopen() question

[tito]

Using fopen() to retrieve data sometimes prevents the page from loading when the other site is not responding.

How can I tell the below to exit after a few seconds of attempting without success and to echo "unable to connect"?

thank you.

<?
$fd= fread(fopen("http://site.com/index.html", "r"), 100000);

if ($fd)

{
$start= strpos($fd, "start point");

$finish= strpos($fd, "endpoint);
$length= $finish-$start;

$code_real=Substr($fd, $start, $length);

}
echo "$code_real";

?>

<?php

 // first set time limit of execution for stcript  (2s)
 set_time_limit(2);

 $unable_connect  = true;

  function time_out() {

global $unable_connect;

 if ($unable_connect) {
    echo 'Unable connect';
 }
  }

  register_shutdown_function("time_out");

// your code goes here

?>

If script is unable connect to server in 2 seconds, than script ends, and before the script ends, will be called function "time_out".

I never been tested this script.

what this code does: if I connects it displays info, and it also display the 'unable connect' previous echo statement.

If it does not connect, it's perfect.

But I am getting close....

If you connect correctly, set up the variable $unable_connect to false.
That's it.

thank you. That solve the mentioned problem but does not echo unable connect if I do not connect.

What if you are trying to fopen a file like "http://mysite.com?a=b&c=d"

Is it able to do that?
