Question

我建立

define('SITE_URL', siteURL()); //returns http://example.com/dir/
define('CKEDITOR', SITE_URL.'plugins/ckeditor/ckeditor.js');

在SITE_URL和full URL又名http://example.com/dir/plugins/ckeditor/ckeditor.js之间查找'差异'的字符串操作是什么，以便我只返回{{1部分？

Answer 1

str_replace($site_url, '', $fullurl);

Answer 2

这是你的答案

function siteURL()
{
    return "http://example.com/dir/";
}

define('SITE_URL', siteURL()); //returns http://example.com/dir/
define('CKEDITOR', SITE_URL.'plugins/ckeditor/ckeditor.js');

// ignore the previous code is just to emulate your constants and functions
// the answer is the following line:

echo str_replace(SITE_URL,'',CKEDITOR);
