另一个 php ereg 修复

我需要从 ereg 到 preg_match 进行一小段编码。这是代码。

function be_file_list($d, $x) {
    foreach (array_diff(scandir($d), array('.', '..')) as $f) {
        if (is_file($d . '/' . $f) && (($x) ? ereg($x.'$',$f) : 1)) {
            $l[] = $f;
        }
    }

    return $l;
}

这段代码可以按预期工作，即使它看起来不太漂亮（来源：http://www.php.net/manual/en/function .scandir.php），

但由于 ereg 已被弃用，我真的很想让它成为 preg_match 或类似的东西。

我整个下午都在搞乱这个，电脑快要被淘汰了。我本以为这

preg_match("/"$x.'$',$f"/")

会起作用，但没有骰子。

任何帮助都会很棒。

干杯本

I have a small chunk of coding I need to take from ereg to preg_match. Here is the code.

This code works as expected even if it doesn't look too pretty

(source: http://www.php.net/manual/en/function.scandir.php)
but as ereg is deprecated, I would really like to make it preg_match, or something like that.
I have been messing with this all afternoon and the PC is about to go out the window. I would have thought that
preg_match("/"$x.'
would have worked but no dice.
Any help would be great.
Cheers

你完全错了......尝试

preg_match('/'.preg_quote($x, '/').'$/', $f)

你写道：

preg_match("/"$x.'
你需要在字符串和变量之间使用 . ，并且你的尾部斜杠位于错误的位置。它需要在模式之后，而不是在主题之后。
,$f"/")

You've got it all wrong... try

preg_match('/'.preg_quote($x, '/').'$/', $f)

You wrote:

preg_match("/"$x.'
You need .s between the strings and vars, and you've got your trailing slash in the wrong place. It needs to be after the pattern, not after the subject. 
,$f"/")
