%09并且+意味著您的字符串中同時包含taband space，因此您需要使用urldecode(),str_replace()來解決這個問題：
<?php
$url = 'https%3A%2F%2F%09%09%09+%09%09%09localhost%2Fwordpress%2Fwp-content%2Fuploads%2FWP-manga%2Fdata%2Fmanga_5e62092804a6d%2Ff6954e41130c0015b5b89a3021d55595%2F12.jpg';
$url_decode = urldecode($url);
$url_decode = str_replace(" ", "", $url_decode);
$url_decode = str_replace("\t", "", $url_decode);
echo $url_decode;
輸出：
https://localhost/wordpress/wp-content/uploads/WP-manga/data/manga_5e62092804a6d/f6954e41130c0015b5b89a3021d55595/12.jpg
