copied!<p>There are a few parts to UUIDs in phpcassa. First, how to generate one. The following functions are useful for this:</p> <pre><code>$my_uuid_string = phpcassa\UUID::uuid1(); $my_uuid_string = phpcassa\UUID::uuid4(); </code></pre> <p>uuid1() generates a v1 UUID, which has a timestamp component, and is called TimeUUIDType in Cassandra. uuid4() generates a totally random UUID, and is called LexicalUUIDType in Cassandra. (The other uuidX() functions aren't generally that useful.) What this function gives you back is a byte array representation of the UUID -- basically a 16 byte string. This is what your <code>"ämªðÏBà=0£Ï‰"</code> string is. When you are trying to insert a UUID into Cassandra, this is what you want to use.</p> <p>It's possible to make a UUID object which has useful methods and attributes from this byte array:</p> <pre><code>$my_uuid = phpcassa\UUID::import($my_uuid_string); </code></pre> <p>With $my_uuid, you can get a pretty string representation like 'd881bf7c-cf8f-11e0-85e5-00234d21610a' by getting <code>$my_uuid->string</code>. You can get back the byte representation by doing <code>$my_uuid->bytes</code>. Any uuid data that you get back from Cassandra will by in the byte array format, so you need to use <code>UUID::import()</code> on it if you want a UUID object.</p> <p>Also, <code>UUID::import()</code> also works on the pretty string representation as well (the one that looks like ''d881bf7c-cf8f-11e0-85e5-00234d21610a').</p> <p>Last, don't forget about the documentation for the <a href="http://thobbs.github.io/phpcassa/api/class-phpcassa.UUID.html" rel="nofollow">UUID class</a>.</p> <p><strong>EDIT</strong>: updated links and class names to match the latest phpcassa API</p>
