PHP Curl Check whether the Web page is included in Baidu

<?php * * Check whether Baidu is included in the page Curl mode * @ param string $url the incoming URL * return int (1 included 0 not included) * * Function Checkbai   
       
Du ($url) {$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://www.bianceng.cn/'); ?>

The other is the most painful way to do the same as pictured

The Preg_match function can be used to detect whether there is "sorry, not found with" this text to determine whether the included

function Checkbaidu ($key) {   
        $url = "http://www.baidu.com/s?wd=". $key;   
        $html = @file_get_contents ($url);   
        $html = Iconv (' utf-8 ', ' gbk//translit ', $html);   
        if (Preg_match (sorry, not found with)/', $html)) {return   
          0;   
        } else {return   
                 1;   
        }   
}
