也许这个...

$new_url = str_replace($string, '/' . $string, $url);

Answer 2

You can use str_replace for this purpose. Just replace category-1 with category-1/

<?php
$url = 'http://localhost/example.com/category-1sub-category-11/products.html';
$string = 'category-1';
$new_url = str_replace($string, $string.'/', $url);

or sub-category-11 with /sub-category-11

<?php
$url = 'http://localhost/example.com/category-1sub-category-11/products.html';
$string = 'sub-category-11';
$new_url = str_replace($string, '/' . $string, $url);

Hope this helps you
