StringHelper: new proposed methods

[tonydspaniard]

• toAscii http://cubiq.org/the-perfect-php-clean-url-generator (not sure whether it should be in Inflector)
• uuid https://gist.github.com/dahnielson/508447

[qiangxue]

toAscii should be moved to Inflector. The slug method may reuse it.

What's the use for uuids? Never used it in PHP apps.

[tonydspaniard]

@samdark The main function of an UUID is being unique.

[samdark]

Why not using microtime or uniqid, for example? Is it really that useful in typical projects?

[tonydspaniard]

In my case, I normally use a custom class:

class HUniqueId
{

    /**
     * Using uniqid() function
     * @param string $prefix
     * @param bool $entropy
     * @param bool $hash
     * @return string
     */
    public static function generateBasic($prefix = '', $entropy = true, $hash = false)
    {
        $id = uniqid($prefix, $entropy);
        return $hash ? md5($id) : $id;
    }

    /**
     * Generate unique using current time + IP
     * @return mixed
     */
    public static function generateByTimeAndIp()
    {
        $timeStamp = date('Ymdhis');
        $ip = $_SERVER['REMOTE_ADDR'];
        $id = "{$timeStamp}-{$ip}";
        return str_replace('.', '', $id);
    }

    /**
     * Generate custom length unique id
     * @param int $length
     * @return string
     */
    public static function generateByLength($length = 10)
    {
        $id = crypt(uniqid(rand(), 1));
        $id = strip_tags(stripslashes($id));
        $id = str_replace('.', '', $id);
        $id = strrev(str_replace('/', '', $id));
        return substr($id, 0, $length);
    }

    /**
     * Generate XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX style unique id,
     * (8 letters)-(4 letters)-(4 letters)-(4 letters)-(12 letters)
     */
    public static function generateGuid()
    {
        $s = strtoupper(md5(uniqid(rand(), true)));
        return
            substr($s, 0, 8) . '-' .
                substr($s, 8, 4) . '-' .
                substr($s, 12, 4) . '-' .
                substr($s, 16, 4) . '-' .
                substr($s, 20);
    }
}

But some people like uuid for its strengh

[tonydspaniard]

ok, we'll leave uuid and move toAscii on Inflector helper
