刪除特殊字符

Question

我保護鏈路具有以下功能

function encode_html5($str){ 
     return '#'.preg_replace("/0{1}([0-9a-f]{3})/i", "$1", implode("", unpack("H*", iconv("UTF-8", "UTF-16BE", $str)))); 
} 

的問題產生一些特殊的字符，我打開文件，vim :set list，在開始處有$然後很多@終於#這是我的鏈接應該開始的地方。

我已經嘗試了很多不同的東西，但似乎沒有任何工作。我已經試過：

$container = encode_html5($container); 
$container = preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '', $container); 
$container = str_replace('$', '', $container); 
$container = str_replace('#', '', $container); 
$container = htmlentities($container); 
$container = preg_replace("/[^0-9]/",'', $container);

Answer 1

這一點很難以具體瞭解你正在嘗試做的，但我想最近我有類似的問題。

嘗試http://php.net/manual/en/function.htmlspecialchars.php並且它在數據傳輸之前就與解碼功能相關聯。

您也可以在使用json_encode之後嘗試html_entity_decode。

我提供的最後一件事是在回聲之前對您的字符串進行json_encode。
