用（？）preg_replace字符串

Question

我有一组字符串，想要替换

/church-ceremony-venues/all/in-quezon-city/church?page=2

至

/church-ceremony-venues/all/in-quezon-city?page=2

我试图从这个问题的答案，但没有任何反应。

Answer 1

$str = "/church-ceremony-venues/all/in-quezon-city/church?page=2";
echo preg_replace("/\/church\?/", "?", $str);

Answer 2

获取最后一个/之前和之后的所有字符? ，则您的新字符串中包含捕获的组$1和$2

$input_lines = "/church-ceremony-venues/all/in-quezon-city/church?page=2";

echo preg_replace("/.([^\?]+)\/.+(\?.+)/", "/$1$2", $input_lines);
