PHP擺脫鏈接

Question

元素我有下面的代碼： -

$link = 'http://www.domain.com/go.php?id=545&url=http://www.example.com/about 

我想URL元素就是 - http://www.example.com/about

Answer 1

$link = 'http://www.domain.com/go.php?id=545&url=http://www.example.com/about'; 

$url = explode("&url=", $link)[1]; 
echo $url; //http://www.example.com/about 

Answer 2

試試這個：

$link = 'http://www.domain.com/go.php?id=545&url=http://www.example.com/about'; 
$uri=explode("url=",$link); 
$uri=$uri[count($uri)-1]; 

echo $uri; 

Answer 3

你可以使用PHP內置的parse_url和parse_str函數納秒。

$link = 'http://www.domain.com/go.php?id=545&url=http://www.example.com/about'; 
parse_str(parse_url($link,PHP_URL_QUERY),$url); 
echo $url['url']; 

Answer 4

function getSomething($url) { 
    if (!(strpos($url, 'url=') !== false)) return false; 
    $parse = explode('url=', $url); 
    $code = $parse[1]; 
    return $code; 
} 

echo getSomething("http://www.domain.com/go.php?id=545&url=http://www.example.com/about"); 

Answer 5

即使網址放在別的地方作爲參數

$link = 'http://www.domain.com/go.php?id=545&url=http://www.example.com/about'; 
$url = ""; 
$params = explode("&", $link); 
for($params as $param){ 
    if(substr($param, 0, 4) === 'url='){ 
     $url = explode("=", $param)[1]; 
     break; 
    } 
} 
echo $url; //http://www.example.com/about
