//following is content , it pull from db($getThread)

[align=left][attach]53[/attach][/align]
content bla bla bla                      content bla bla bla
[align=left][attach]52[/attach][/align]
content bla bla bla


content bla bla bla
//main content end

//following is attachment file
[0] => Array ( [aid] => 53 [tid] => 32 [pid] => 32 [uid] => 1 [filesize] => 152633 [attachment] => 201305/22/142619h42az34077hhra0p.jpg [width] => 1080 ) 
[1] => Array ( [aid] => 52 [tid] => 32 [pid] => 32 [uid] => 1 [filesize] => 89015 [attachment] => 201305/22/142618wx3njhgf3n883zxr.jpg [width] => 1080 )

我如何使用 preg_replace 将 [attach]53[/attach] 更改为

src 从数组中获取aid=53，因为它也是 [attach]53[/attach] 和宽度

我尝试了以下方法，但出现错误，我知道这样做是错误的，因为 $attachmentContainer[$1]['attachment'] 以 0 开头，而 53 不存在，卡住了，不知道该怎么做。

$threadContainer = preg_replace('/\[attach\](.*?)\[\/attach\]/i', '<img src="' . $attachmentContainer[$1]['attachment'] . '" width="' . $attachment[$1]['width'] . '" />', $getThread['message']);

我的问题：用 javascript 或 php 做得更好？我如何在 db 中使用正确的 src 和宽度存储 preg_replace 所有 [attach][/attach] ？并检查内容，我如何处理这些“空格”来
换行？

我正在尝试拉 discuz！x3.0 线程内容直接来自 db。

感谢您的教导！

我不太明白你想要什么，但是从你的最后一段代码中我会说你需要preg_replace_callback，因为在调用$attachmentContainer[$1]['attachment']之前不应该评估。preg_replace

因此，您的最后一段代码应如下所示：

$threadContainer = preg_replace_callback(
    '/\[attach\](.*?)\[\/attach\]/i',
    function ($matches) {
        return '<img src="' . $attachmentContainer[$matches[1]]['attachment'] . '" width="' . $attachment[$matches[1]]['width'] . '" />';
    },
    $getThread['message']
);
