PHP实现百度收录量API查询实例代码

今天给大家分享一个php的百度收录查询api源码，大家可自行封装为接口。

<?php

$domain = (isset($_GET['domain']))?$_GET['domain']:$_POST['domain'];
if(empty($domain))  echo '查询域名不能为空';

$count = baiduSL ($domain);

if(!isset($count))  showjson(array('code'=>200502,'msg'=>'查询失败，请重试！'));
if(!$count)  $count = 0;
$result=array(
	'code'=>1,
	'domain'=>$domain,
	'data'=>$count
);
print_r(json_encode($result));

unset($value,$url_arr,$domain,$row,$hostrow,$site,$resulturl,$result,$ch);
function baiduSL ($domain) {
	 $baidu='https://www.baidu.com/s?ie=utf-8&tn=baidu&wd=site%3A'.$domain; 
	 $bdsite=BD_curl($baidu); 

	 $bdsite = str_replace(array("\r\n", "\r", "\n", '    '), '', $bdsite); 
	 preg_match('/该网站共有(.*?)个网页被百度收录/i',$bdsite,$count);
	 if (!$count) preg_match('/找到相关结果数约(.*?)个/i',$bdsite,$count);
	 //ereg('该网站共有(.*)个网页被百度收录', $bdsite,$count); 
	 //print_r($count);
	 //$count=str_replace('该网站共有','',$count); 
	 //$count=str_replace('个网页被百度收录','',$count); 
	 $count = str_replace(array("\r\n", "\r", "\n", ',', ' '), '', $count); 
	 $baiduSL=strip_tags($count[1]); 
	 unset($count);
	 return $baiduSL;
