PHP implementation of the bulk test site can be opened to the normal method _php skills

This article describes the PHP implementation of the bulk test site can be opened in a normal way. Share to everyone for your reference, specific as follows:

curl_setopt function is an important function in PHP, it can imitate user's some behavior, such as imitate user login, register and so on some user can manipulate behavior.

<?php
//Set maximum execution time is 120 seconds
ini_set (' max_execution_time ',);
function Httpcode ($url) {
  $ch = Curl_init ();
  $timeout = 3;
  curl_setopt ($ch, curlopt_followlocation,1);
  curl_setopt ($ch, curlopt_returntransfer,1);
  curl_setopt ($ch, Curlopt_header, 1);
  curl_setopt ($ch, Curlopt_connecttimeout, $timeout);
  curl_setopt ($ch, Curlopt_url, $url);
  Curl_exec ($ch);
  return $httpcode = Curl_getinfo ($ch, curlinfo_http_code);
  Curl_close ($ch);
$check _web = Array (
' http://www.jb51.net/', '
http://sc.jb51.net/', '
http://tools.jb51.net/',
' http://baike.jb51.net/',
' http://demo.jb51.net/', '
http://demo2.jb51.net/',
);
For ($i =0 $i <count ($check _web), $i + +) {
  echo $check _web[$i]. '-> '. Httpcode ($check _web[$i]). ' <br> ';
}
