剥离 php 变量,用破折号替换空格

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

我需要使它全部小写,删除所有特殊字符,并用破折号替换空格。

这个函数将创建一个 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:)

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

例如:

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;
}

是的,如果您想处理任何特殊字符,您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)));
