php获取网页标题和内容函数（不包含html标签）

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 $store = preg_replace("/<mce:script.*><!-- (.*)<\/script>/smUi",'',$store); //remove link $store = preg_replace("/<link\s+[^>]+>/smUi",'',$store); //remove <!-- --> $store = preg_replace("/<!--.*-->/smUi",'',$store); //remove <style </<style> $store = preg_replace("/<style.*>(.*)<\/style>/smUi",'',$store); //remove 中文空格 $store = preg_replace("/　/",'',$store); //remove 标点符号 //$store = preg_replace("/[\~`!@#$%^&*()_\-+={}|\[\]\\;':"\<\>\?\,\.\/]/",'',$store); //preg_match("/<head.*>(.*)<\/head>/smUi",$store, $matches); //$head = $matches[1]; //echo $head.

使用例子

$a = getPageContent(www.ttphp.com); print_r($a);
