有人能帮忙吗
演示
捕获组1中的“3”
,替换中的/$1/
作为“/3/”
捕获()之间的值,并通过$1将其投影回:
$string = "list page.php?cpage=1, list page.php?cpage=2, list page.php?page=3 thats all";
$string = preg_replace("/\?c?page=([0-9]{1,})/", "/$1/", $string);
echo $string;
([0-9]{1,})
表示一个或多个数字。
希望这有帮助。您有什么问题吗?
preg_replace("/\?c?page=([0-9]+)/", "/$1/", "page.php?cpage=3");
$string = "list page.php?cpage=1, list page.php?cpage=2, list page.php?page=3 thats all";
$string = preg_replace("/\?c?page=([0-9]{1,})/", "/$1/", $string);
echo $string;
