str_replace通过在单词php之后添加斜杠

Question

基本上我有这个网址http://xxxxxxx.xxx/example.com/category-1sub-category-11/products.html，我有这个字符串sub-category-11，我想在字符串之前添加一个斜杠：http://xxxxx.xxx/example.com/category-1/sub-category-11/products.html。

$url = 'http://localhost/example.com/category-1sub-category-11/products.html';
$string = 'sub-category-11';
$new_url = preg_replace('/\b'.$string.'\b/', '/'.$string, $url);

对此有何帮助？很感激。

Answer 1

也许这......

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

Answer 2

您可以将str_replace用于此目的。只需将category-1替换为category-1 /

即可

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

或子类别-11与/ 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);

希望这有助于你
