去掉php变量，用破折号替换空格

Question

如何将一个PHP变量从“My company & My Name”转换为“my-company-my-name”？

我需要将它全部小写，删除所有特殊字符并用破折号替换空格。

Answer 1

此功能将创建一个搜索引擎友好的字符串

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; 
} 

应该罚款:)

更换特定的字符： 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; 
}

烨，和如果你想处理任何特殊的字符你需要在模式中声明它们，否则它们可能会被刷新。你可以这样做的：

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