(PHP 5)

com_create_guid — グローバルユニーク ID (GUID) を生成する

説明

string com_create_guid ( void )

Globally Unique Identifier (GUID) を生成し、文字列で返します。 GUID は DCE UUID と同様の方法で生成されますが、Microsoft の 規約により、GUID が中括弧で囲まれるという点が異なります。

PECL uuid 拡張モジュールの uuid_create() も参照ください。

function_exists('com_create_guid')){
        return
com_create_guid();
    }else{
       
mt_srand((double)microtime()*10000);//optional for php 4.2.0 and up.
       
$charid = strtoupper(md5(uniqid(rand(), true)));
       
$hyphen = chr(45);// "-"
       
$uuid = chr(123)// "{"
               
.substr($charid, 0, 8).$hyphen
               
.substr($charid, 8, 4).$hyphen
               
.substr($charid,12, 4).$hyphen
               
.substr($charid,16, 4).$hyphen
               
.substr($charid,20,12)
                .
