从名称生成适当的链接

Question

I am attempting to generate proper links from proper names...

For example: T & J Automotive is currently generated as /t-j-automotive

But, because I need to do a look up based on the name, I am unable to do said lookup when attempting to convert back to the name.

So... I've take care of ' by converting them to _, which works great for names like Mike's Shop (converts to mike_s-shop), but now I am faced with the &

Here is my current function:

// Fix the name for a SEO friendly URL
function FixNameForLink($str){
    // Swap out Non "Letters" with a -
    $text = preg_replace('/[^\\pL\d\']+/u', '-', $str);
    // Trim out extra -'s
    $text = trim($text, '-');
    // Convert letters that we have left to the closest ASCII representation
    $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    // Make text lowercase
    $text = strtolower($text);
    // ' has been valid until now... swap it for an _
    $text = str_replace('\'', '_', $text);
    // & has been valid until now... swap it for an .
    $text = str_replace('&', '.', $text);
    // Strip out anything we haven't been able to convert
    $text = preg_replace('/[^-_\w]+/', '', $text);
    return $text;
}

Note, the & replacement is not happenning. How can I make sure that any string passed to this function will have ' replace with _, and & replaced with .?

Fixed:

// Fix the name for a SEO friendly URL
function FixNameForLink($str){
    // Swap out Non "Letters" with a -
    $text = preg_replace('/[^\\pL\d\'&]+/u', '-', $str); // needed to allow the &
    // Trim out extra -'s
    $text = trim($text, '-');
    // Convert letters that we have left to the closest ASCII representation
    $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    // Make text lowercase
    $text = strtolower($text);
    // ' has been valid until now... swap it for an _
    $text = str_replace('\'', '_', $text);
    // & has been valid until now... swap it for an .
    $text = str_replace('&', '.', $text);
    // Strip out anything we haven't been able to convert
    $text = preg_replace('/[^-_\.\w]+/', '', $text); // needed to make sure the replace . stays put 
    return $text;
