This function will create an SEO friendly string
此函数将创建一个 SEO 友好的字符串
function seoUrl($string) {
//Lower case everything
$string = strtolower($string);
//Make alphanumeric (removes all other characters)
$string = preg_replace("/[^a-z0-9_\s-]/", "", $string);
//Clean up multiple dashes or whitespaces
$string = preg_replace("/[\s-]+/", " ", $string);
//Convert whitespaces and underscore to dash
$string = preg_replace("/[\s_]/", "-", $string);
return $string;
}
should be fine :)
应该没事 ：）

Replacing specific characters: http://se.php.net/manual/en/function.str-replace.php
替换特定字符：http: //se.php.net/manual/en/function.str-replace.php
Example:
例子：
function replaceAll($text) {
$text = strtolower(htmlentities($text));
$text = str_replace(get_html_translation_table(), "-", $text);
$text = str_replace(" ", "-", $text);
$text = preg_replace("/[-]+/i", "-", $text);
return $text;
}

Yop, and if you want to handle any special characters you'll need to declare them in the pattern, otherwise they may get flushed out. You may do it that way:
是的，如果你想处理任何特殊字符，你需要在模式中声明它们，否则它们可能会被刷新。你可以这样做：
strtolower(preg_replace('/-+/', '-', preg_replace('/[^\wáéíóú]/', '-', $string)));
