去掉php變量，用破折號替換空格

Question

如何將一個PHP變量從「My company & My Name」轉換爲「my-company-my-name」？

我需要將它全部小寫，刪除所有特殊字符並用破折號替換空格。

Answer 1

此功能將創建一個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; 
} 

應該罰款:)

更換特定的字符： 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; 
}

燁，和如果你想處理任何特殊的字符你需要在模式中聲明它們，否則它們可能會被刷新。你可以這樣做的：

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