如何使用 preg_replace(_callback) 依次替换主题标签文本

发布于 2024-12-14 11:22:24 字数 921 浏览 1 评论 0原文

目标文本类似于：

Lorem ipsum dolor #sit# amet, consectetur #adipisicing# elit, sed do #eiusmod# tempor incididunt ut Labore et dolore magna aliqua。 Ut enim ad minim veniam, quis nostrud exeritation ullamco Laboris nisi ut aliquip.

标签 #sit#、#adipisicing#、#eiusmod# 的核心对应数据将类似于数组：

array(
  '42' => 'sit somewhere',
  '43' => 'adipisicing...',
  '63' => 'eiusmod...'
)

我想使用 preg_replace 或 preg_replace_callback 来按顺序替换数组值标记的标签。得到的结果是：

Lorem ipsum dolor <a href="/link/to/42" title="sit somewhere">#sit#</a> amet, consectetur <a href="link/to/43" title="adipisicing...">#adipisicing#</a> elit, sed do <a href="/link/to/63" title="eiusmod...">#eiusmod#</a> tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip.

如何实现？

原文

the target text is something like:

Lorem ipsum dolor #sit# amet, consectetur #adipisicing# elit, sed do #eiusmod# tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip.

the coresponding data to hashtagged #sit#, #adipisicing#, #eiusmod# would be array like:

array(
  '42' => 'sit somewhere',
  '43' => 'adipisicing...',
  '63' => 'eiusmod...'
)

i want to use preg_replace or preg_replace_callback to replace the hashtagged by the array value in sequence. to get result as:

Lorem ipsum dolor <a href="/link/to/42" title="sit somewhere">#sit#</a> amet, consectetur <a href="link/to/43" title="adipisicing...">#adipisicing#</a> elit, sed do <a href="/link/to/63" title="eiusmod...">#eiusmod#</a> tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip.

how could that be achieved?

$search = array(
    '#sit#',
    '#adipisicing#',
    '#eiusmod#'
    );
$replacement = array(
    '42' => 'sit somewhere',
    '43' => 'adipisicing...',
    '63' => 'eiusmod...'
    );
$str = str_replace($search, $replacement, $str);

$search = array(
    '#sit#',
    '#adipisicing#',
    '#eiusmod#'
    );
$replacement = array(
    '42' => 'sit somewhere',
    '43' => 'adipisicing...',
    '63' => 'eiusmod...'
    );
$str = str_replace($search, $replacement, $str);
