本文实例讲述了PHP简单实现短网址还原的方法。分享给大家供大家参考，具体如下：
这里以编程之家//www.jb51.cc的短网址http://t.cn/heEHwk为例运行效果截图如下：
具体代码如下：
PHP;">
PHP
$info1 = '亲！暂不能解析此类短网址。';
$info2 = '亲！网址解析失败，请重试。';
$info3 = '
>'; $info5 = '亲！不是短网址或无效。'; function unshort($url) { global $info1,$info2,$info3,$info4; $curl = curl_init(); curl_setopt($curl,CURLOPT_URL,$url); curl_setopt($curl,CURLOPT_RETURNTRANSFER,1); curl_setopt ($curl,CURLOPT_USERAGENT,'Mozilla/8.0 (compatible; MSIE 8.0; Windows 7'); curl_setopt($curl,CURLOPT_HEADER,1); curl_setopt($curl,CURLOPT_NOBODY,0); curl_setopt($curl,CURLOPT_TIMEOUT,15); curl_setopt($curl,CURLOPT_ENCODING,'gzip'); $data = curl_exec($curl); if(!empty($data)){ $message = curl_getinfo($curl); curl_close($curl); $status = $message['http_code']; if ($status == '301' || $status == '302' ){ $UrlHeader = (get_headers($url,1)); $unurl = $UrlHeader[Location]; if(is_array($unurl)) { $unurl = $unurl[0]; $unurl .=$info3.$unurl.$info4; return $unurl; } else { $unurl .=$info3.$unurl.$info4; return $unurl; } } return $info1; } return $info2; } function adfunshort($url) { global $info3,$info4,$info5; $c = file_get_contents($url); $p = "/url = '(.*)';/isU"; preg_match($p,$c,$content); $unurl = $content[1]; if($unurl == '') { return $info5; } else { $unurl .=$info3.$unurl.$info4; return $unurl; } } ?>
>'; $info5 = '亲！不是短网址或无效。'; function unshort($url) { global $info1,$info2,$info3,$info4; $curl = curl_init(); curl_setopt($curl,CURLOPT_URL,$url); curl_setopt($curl,CURLOPT_RETURNTRANSFER,1); curl_setopt ($curl,CURLOPT_USERAGENT,'Mozilla/8.0 (compatible; MSIE 8.0; Windows 7'); curl_setopt($curl,CURLOPT_HEADER,1); curl_setopt($curl,CURLOPT_NOBODY,0); curl_setopt($curl,CURLOPT_TIMEOUT,15); curl_setopt($curl,CURLOPT_ENCODING,'gzip'); $data = curl_exec($curl); if(!empty($data)){ $message = curl_getinfo($curl); curl_close($curl); $status = $message['http_code']; if ($status == '301' || $status == '302' ){ $UrlHeader = (get_headers($url,1)); $unurl = $UrlHeader[Location]; if(is_array($unurl)) { $unurl = $unurl[0]; $unurl .=$info3.$unurl.$info4; return $unurl; } else { $unurl .=$info3.$unurl.$info4; return $unurl; } } return $info1; } return $info2; } function adfunshort($url) { global $info3,$info4,$info5; $c = file_get_contents($url); $p = "/url = '(.*)';/isU"; preg_match($p,$c,$content); $unurl = $content[1]; if($unurl == '') { return $info5; } else { $unurl .=$info3.$unurl.$info4; return $unurl; } } ?>
PHP
$turl = $_POST['turl']?$_POST['turl']:"";
$url_done= $_POST['url_done']?$_POST['url_done']:"";
if ($url_done == 'done'){
$http = substr($turl,7);
if ($http != 'http://' && $http != 'https:/'){
$turl = 'http://'.$turl;
}
$tturl = substr($turl,11);
if ($tturl == 'http://adf.'){
$longurl = adfunshort($turl);
}else {
$longurl = unshort($turl);
}echo "短网址 ".$turl." 的真实网址为：
$longurl "; } ?>
$longurl "; } ?>
