How do I...check a session to see if it contains a word & if present echo a statement

[Benny007]

Hi,

I would like to know how to check a session - to see if it contains 2 letters at the begining of a certain word. - and if it does echo "statement";

i.e

$_SESSION['cart']

I have items with ID's that start with 2 letters and then 3 numbers i.e

FF345, FF561, OF456 (Nice and simple)

Now how would I check a session to see if it contains an item with the ID "OF"
at the start?

And if any item that starts with "OF" is present then simply echo "Something Here";
?

I'm sure this is easy for most of you, but i'm finding it a challenge.

Hope you can help.

Cheers

Same way you'd check any other variable.
Look up regular expressions. In fact, if all you need to do is see if there is an "OF" in there, [man]strpos[/man] would be enough.
And consider storing those IDs in an array instead of a string.
