從數據剝離所有$ _POST和$ _GET

Question

我正在尋找preg_replace方法從字符串中剝離所有$_GET['whatever']和所有$_POST['values']。

例如，如果字符串是：

$str = "this is some text with $_POST['foo'] within it - and some $_GET['bar'] as well"; 

我想擁有它返回：

$str = "this is some text with within it - and some as well"; 

感謝。

Answer 1

你寫的assingnment將不會運行，因爲字符串內的引號會導致語法錯誤。你需要逃避它們，例如

$str = 'this is some text with $_POST[\'foo\'] within it - and some $_GET[\'bar\'] as well'; 

假如你這樣做，你可以刪除這些字符串有：

$str = preg_replace('/\$_(GET|POST)\[[^]]+\]/', '', $str); 

這將工作，只要你沒有嵌套在括號內的任何數組引用。
