Create a GUID in PHP

PHP

Its easy to make GUIDs in PHP. Below is clean code using windows COM to get GUIDs. When the PHP creates GUIDs or UUIDs they are V4 guids.

$guid = com_create_guid();
echo $guid;

If you are not a on windows based platform you can roll this code for making GUIDs in PHP

function getGUID(){
    if (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)
            .chr(125);// "}"
        return $uuid;
    }
}

To use the above functon:

$GUID = getGUID();
echo $GUID;
