下面给出一段php函数,功能是检测一个网页是否被百度收录,直接给出代码

使用:传入一个网址,如 http://jb51.net/article/1.html ,返回1,代表已经收录;返回0,代表百度没有收录。

<?php
header("Content-type: text/html; charset=utf-8");

function checkBaidu($url) { $url = 'http://www.baidu.com/s?wd=' . $url;

$curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $rs = curl_exec($curl); curl_close($curl);

$arr = parse_url($url);

if (strpos($arr['query'], 'http://')) { $arr['query'] = str_replace('http://', '', str_replace('wd=', '', $arr['query'])); } else { $arr['query'] = str_replace('wd=', '', $arr['query']); }

if (strpos($arr['query'], '?')) { $str = strstr($arr['query'], '?'); $arr['query'] = str_replace($str, '', $arr['query']); }

if (strpos($arr['query'], '/')) { $narr = explode('/', $arr['query']); $arr['query'] = $narr[0]; }

if (strpos($rs, '<b>'.$arr['query'].'</b>')) { return 1; } else { return 0; } }

echo checkBaidu('http://jb51.net/article/1.html'); ?>
