更新

由于这个答案引起了一些关注，我在这里添加了一些解释。

所提供的解决方案基本上将用-(连字符)替换除A-Z、A-Z、0-9和-(连字符)之外的所有内容。因此，它不能与其他unicode字符(URL段码/字符串的有效字符)正常工作。一种常见的情况是输入字符串包含非英语字符。

只有当您确信输入字符串不会包含unicode字符时才使用此解决方案，您可能希望这些字符成为output/slug的一部分。

如。“नारीशक्ति”将成为 "----------" ( 连字符)而不是“नारी——शक्ति”(有效的URL蛞蝓)。

回答

$slug = strtolower(trim(preg_replace('/[^A-Za-z0-9-]+/', '-', $string)));

这可能也是一种方法。灵感来自这些链接专家交流和alinalexander

function slugifier($txt){

   /* Get rid of accented characters */
   $search = explode(",","ç,æ,œ,á,é,í,ó,ú,à,è,ì,ò,ù,ä,ë,ï,ö,ü,ÿ,â,ê,î,ô,û,å,e,i,ø,u");
   $replace = explode(",","c,ae,oe,a,e,i,o,u,a,e,i,o,u,a,e,i,o,u,y,a,e,i,o,u,a,e,i,o,u");
   $txt = str_replace($search, $replace, $txt);

   /* Lowercase all the characters */
   $txt = strtolower($txt);

   /* Avoid whitespace at the beginning and the ending */
   $txt = trim($txt);

   /* Replace all the characters that are not in a-z or 0-9 by a hyphen */
   $txt = preg_replace("/[^a-z0-9]/", "-", $txt);
   /* Remove hyphen anywhere it's more than one */
   $txt = preg_replace("/[\-]+/", '-', $txt);
   return $txt;   
}

如果你的弹头只包含A-Za-z0-9-那么这对你来说是可以的

function sanitize_slug($text)
{
    $text = preg_replace('/[^A-Za-z0-9-]+/', '-', $text);
    $text = trim($text, '-');
    $text = preg_replace('~-+~', '-', $text);
    return $text;
}

注意:我已经从wordpress和它的工作!!

像这样使用它:

echo sanitize('testing this link');

Code

//taken from wordpress
function utf8_uri_encode( $utf8_string, $length = 0 ) {
    $unicode = '';
    $values = array();
    $num_octets = 1;
    $unicode_length = 0;

    $string_length = strlen( $utf8_string );
    for ($i = 0; $i < $string_length; $i++ ) {

        $value = ord( $utf8_string[ $i ] );

        if ( $value < 128 ) {
            if ( $length && ( $unicode_length >= $length ) )
                break;
            $unicode .= chr($value);
            $unicode_length++;
        } else {
            if ( count( $values ) == 0 ) $num_octets = ( $value < 224 ) ? 2 : 3;

            $values[] = $value;

            if ( $length && ( $unicode_length + ($num_octets * 3) ) > $length )
                break;
            if ( count( $values ) == $num_octets ) {
                if ($num_octets == 3) {
                    $unicode .= '%' . dechex($values[0]) . '%' . dechex($values[1]) . '%' . dechex($values[2]);
                    $unicode_length += 9;
                } else {
                    $unicode .= '%' . dechex($values[0]) . '%' . dechex($values[1]);
                    $unicode_length += 6;
                }

                $values = array();
                $num_octets = 1;
            }
        }
    }

    return $unicode;
}

    // Remove percent signs that are not part of an octet.
    $title = str_replace('%', '', $title);
    // Restore octets.
    $title = preg_replace('|---([a-fA-F0-9][a-fA-F0-9])---|', '%$1', $title);

    if (seems_utf8($title)) {
        if (function_exists('mb_strtolower')) {
            $title = mb_strtolower($title, 'UTF-8');
        }
        $title = utf8_uri_encode($title, 200);
    }

    $title = strtolower($title);
    $title = preg_replace('/&.+?;/', '', $title); // kill entities
    $title = str_replace('.', '-', $title);
    $title = preg_replace('/[^%a-z0-9 _-]/', '', $title);
    $title = preg_replace('/\s+/', '-', $title);
    $title = preg_replace('|-+|', '-', $title);
    $title = trim($title, '-');

    return $title;
}

如果使用Core中已经实现的东西呢?

//Clean non UTF-8 characters    
Mage::getHelper('core/string')->cleanString($str)

或者核心url/ url重写方法之一..
