Your preg_replace usage is incorrect, but you don't need a regex for this anyway. For static replacements just use str_replace.

您的preg_replace使用不正确，但无论如何您都不需要正则表达式。对于静态替换，只需使用str_replace。

$url = 'http://localhost/../images/';
$url = str_replace('..', '', $url);

but your probably also should include the / in the search.

但你可能也应该在搜索中包含/。

Your preg_replace is inverted the pattern is the first parameter and the replacement value second. http://php.net/manual/en/function.preg-replace.php

你的preg_replace被反转，pattern是第一个参数，第二个是替换值。 http://php.net/manual/en/function.preg-replace.php

So the correct preg_replace would be:

所以正确的preg_replace将是：

$url = 'http://localhost/../images/';
$final = preg_replace('/\.\./', '/', $url);

Also this is putting a third / between the domain and directory. The /s are delimiters in the pattern, did you mean for that?

这也是域和目录之间的第三个/。 / s是模式中的分隔符，你的意思是什么？

Note the .s are special characters and need to be escaped.

请注意.s是特殊字符，需要进行转义。
