如何将 PHP 变量从“My company & My Name”转换为“my-company-my-name”?

我需要全部小写,删除所有特殊字符并用破折号替换空格。

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;
}

应该没事 :)

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,否则它们可能会被清除。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;
}
