如何用PHP清理标题URI?

许多CMS已经实现了类似的功能, the one of Wordpress 已在中发布 another question . 您可能对 question about this technique 一般来说,也是。

这可能是用单个连字符替换任何非字母数字字符的最短方法:

trim(preg_replace('/[^a-z0-9-]+/', '-', strtolower($str)), '-')

Here's how drupal does it .

如果现场出现故障:

<?php
function pathauto_cleanstring($string)
{
    $url = $string;
    $url = preg_replace('~[^\\pL0-9_]+~u', '-', $url); // substitutes anything but letters, numbers and '_' with separator
    $url = trim($url, "-");
    $url = iconv("utf-8", "us-ascii//TRANSLIT", $url); // TRANSLIT does the whole job
    $url = strtolower($url);
    $url = preg_replace('~[^-a-z0-9_]+~', '', $url); // keep only letters, numbers, '_' and separator
    return $url;
}

一般来说,您希望您的URL只有0-9和a-z,并确保所有内容都是小写的。用破折号(-)替换空格,去掉其余的乱码。

这件事已经解决了。
