I'm working on a web service which requires a new GUID() passed as a reference to a method within the service.
I am not familiar with C# or the GUID() object, but require something similar for PHP (so create a new object which from my understanding returns an empty/blank GUID).
Any ideas?

Open Visual Studio->Tools->Create GUID->Registry Format->New GUID. It will create a new GUID every time you click New GUID.
A GUID (globally unique identifier) is a 128-bit text string that represents an identification (ID). Organizations generate GUIDs when a unique reference number is needed to identify information on a computer or network. A GUID can be used to ID hardware, software, accounts, documents and other items.
-- If you want to generate a new Guid (uniqueidentifier) in SQL server the you can simply use the NEWID() function. -- This will return a new random uniqueidentifier e.g. You can directly use this with INSERT statement to insert new row in table.
You can try the following:
function GUID() { if (function_exists('com_create_guid') === true) { return trim(com_create_guid(), '{}'); } return sprintf('%04X%04X-%04X-%04X-%04X-%04X%04X%04X', mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(16384, 20479), mt_rand(32768, 49151), mt_rand(0, 65535), mt_rand(0, 65535), mt_rand(0, 65535)); } Source - com_create_guid

As an alternative to the above options:
$guid = bin2hex(openssl_random_pseudo_bytes(16)); It gives a string like 412ab7489d8b332b17a2ae127058f4eb
