Why not make your inventory identifier field a unique index:
ie:
alter table inventory add unique itemid (itemid);
Now, whenever someone tries to create a duplicate item identifier,
MySQL will issue an error, which your script can capture. I don't use PHP, but do use
VB through MyODBC, and this is how I catch unwanted duplicates.
