去掉 php 变量，用破折号替换空格

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;
}

应该没问题:)

> 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，否则它们可能会被冲掉。你可以这样做：

strtolower(preg_replace('/-+/', '-', preg_replace('/[^'wáéíóú]/', '-', $string)));

替换特定字符：http://se.php.net/manual/en/function.str-replace.php

例：

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;
}
