       is generated.

	      o $seconds
		- The seconds part of the timeout to be set.

EXAMPLES
       Example #1

	      stream_set_timeout(3) example

	      <?php
	      $fp = fsockopen("www.example.com", 80);
	      if (!$fp) {
		  echo "Unable to open
";
	      } else {

		  fwrite($fp, "GET / HTTP/1.0

");
		  stream_set_timeout($fp, 2);
		  $res = fread($fp, 2000);

		  $info = stream_get_meta_data($fp);
		  fclose($fp);

		  if ($info['timed_out']) {
		      echo 'Connection timed out!';
		  } else {
		      echo $res;
		  }

	      }
	      ?>

NOTES
       Note

	       This function doesn't work with advanced operations like stream_socket_recvfrom(3), use	stream_select(3)  with	timeout  parameter
	      instead.

	This function was previously called as set_socket_timeout(3) and later socket_set_timeout(3) but this usage is deprecated.
