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)));
