Check for duplicates in array

[samtwilliams]

Hi All,

 

 

I have the following array with Partnumber & Qty, I can't seem to find a clean way to check if the partnumber already exists. Because if it does i want to return a message to the user.

 

I load my array like this;

 

	$item_array = array($_POST['medsel'], $_POST['qty']);
array_push($_SESSION['ItemTotalArray'],$item_array);

 

Example Data; (as you can see i have duplicates which i want to prevent)

 

Array ( [0] => Array ( [0] => CD0003 [1] => 1 ) [1] => Array ( [0] => NA [1] => 1 ) [2] => Array ( [0] => CD0002 [1] => ) [3] => Array ( [0] => CD0001 [1] => 3 ) [4] => Array ( [0] => CD0005 [1] => 1 ) [5] => Array ( [0] => NA [1] => ) [6] => Array ( [0] => NA [1] => ) [7] => Array ( [0] => NA [1] => 2 ) ) 

 

Thanks

Sam

You can use the in_array function to check before inserting.
