PHP 获取百度和搜狗收录量代码

<?php 
function baiduSl($url){ 
 $baidu="http://www.baidu.com/s?wd=site:".$url; 
 $site=file_get_contents($baidu); 
 ereg("该网站共有(.*)个网页被百度收录", $site,$count); 
 $count=str_replace("该网站共有","",$count); 
 $count=str_replace("个网页被百度收录","",$count); 
 $count=str_replace(",","",$count); 
 $count=str_replace(" ","",$count); 
 return strip_tags($count[0]); 
} 
function sogouSl($url){ 
 $sogou="http://www.sogou.com/web?query=site:".$url; 
 $site=file_get_contents($sogou); 
 ereg("找到约 (.*) 条结果", $site,$count); 
 $count=str_replace("找到约","",$count); 
 $count=str_replace("条结果","",$count); 
 $count=str_replace(",","",$count); 
 $count=str_replace(" ","",$count); 
 return strip_tags($count[0]); 
}
?>

调用代码<?php echo baiduSl('www.hulingweb.cn');?> <?php echo sogouSl('www.hulingweb.cn');?>
