I am trying to remove all backslashes from a url-decoded string, but it is outputting \ rather than outputting the url-decoded string with \ removed.
我试图从url解码的字符串中删除所有反斜杠，但它输出\而不是输出已删除的url解码字符串。
Please can you tell me my problem.
请你告诉我我的问题。
<?php
$json = $_GET['ingredients'];
echo urldecode(str_replace($json,$json, "\\"));
?>
