我有这样的正则表达式:
^page/(?P<id>\d+)-(?P<slug>[^\.]+)\.html$
和一个数组:
$args = array(
'id' => 5,
'slug' => 'my-first-article'
);
我想有功能:
my_function($regex, $args)
将返回此结果:
page/5-my-first-article.html
如何实现这一目标?

有趣的挑战,我编写了适用于此示例的内容,请注意您需要PHP 5.3+才能使此代码正常工作:
$regex = '^page/(?P<id>\d+)-(?P<slug>[\.]+)\.html$';
$args = array(
'id' => 5,
'slug' => 'my-first-article'
);
$result = preg_replace_callback('#\(\?P<(\w+)>[^\)]+\)#', function($m)use($args){
if(array_key_exists($m[1], $args)){
return $args[$m[1]];
}
}, $regex);
$result = preg_replace(array('#^\^|\$$#', '#\\\\.#'), array('', '.'), $result); // To remove ^ and $ and replace \. with .
echo $result;
输出: page/5-my-first-article.html
