php获取网页标题和内容函数(不包含html标签)

有时候我们需要获取网页的标题与内容，就是个采集函数，这里简单分享下，方便需要的朋友

复制代码 代码如下:

function getPageContent($url) {  

        //$url='http://www.ttphp.com;  

        $pageinfo = array();  
        $pageinfo[content_type] = '';  
        $pageinfo[charset] = '';  
        $pageinfo[title] = '';  
        $pageinfo[description] = '';  
        $pageinfo[keywords] = '';  
        $pageinfo[body] = '';  
        $pageinfo['httpcode'] = 200;  
        $pageinfo['all'] = '';   

        $ch = curl_init();  
        curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");  
        curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);  
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);  
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,0);  
        curl_setopt($ch, CURLOPT_TIMEOUT, 8);  
        curl_setopt($ch, CURLOPT_FILETIME, 1);  
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  
        //curl_setopt($ch, CURLOPT_HEADER, 1);        
        curl_setopt($ch, CURLOPT_URL,$url);  

        $curl_start = microtime(true);  
        $store = curl_exec ($ch);  

        $curl_time = microtime(true) - $curl_start;  
        if( curl_error($ch) ) {  
            $pageinfo['httpcode'] = 505;  //gate way error  
            echo 'Curl error: ' . curl_error($ch) ."/n";  
            return $pageinfo;  
        }  

        //print_r(curl_getinfo($ch));  
        $pageinfo['httpcode'] = curl_getinfo($ch,CURLINFO_HTTP_CODE);  
        //echo curl_getinfo($ch,CURLINFO_CONTENT_TYPE)."/n";  
        $pageinfo[content_type] = curl_getinfo($ch,CURLINFO_CONTENT_TYPE);  
        if(intval($pageinfo['httpcode']) 200 or !preg_match('@text/html@',curl_getinfo($ch,CURLINFO_CONTENT_TYPE) )   ) {  
                //print_r(curl_getinfo($ch) );  
                //exit;  
                return $pageinfo;  
        }  
        preg_match('/charset=([^/s/n/r]+)/i',curl_getinfo($ch,CURLINFO_CONTENT_TYPE),$matches); //从header 里取charset  
        if( trim($matches[1]) ) {  
            $pageinfo[charset] = trim($matches[1]);  
        }  
        //echo $pageinfo[charset];  
        //exit;  
        curl_close ($ch);  
        //echo $store;  

 
        //remove javascript  
        $store = preg_replace("/  
        $store = preg_replace("//smUi",'',$store);  
        //remove

使用例子

复制代码 代码如下:

$a = getPageContent();  
print_r($a);
