Check Array For Blanks

[qwertyjjj]

I have data as below.

 

I can't do this check in the SQL because my server is still on v 4 so I have to do it in PHP code.

 

If there is a blank line linked to an order ID but that orderID also has a PayPal entry then it's ok, I want to delete it from the array.

 

However, if it hast an OrderID and everything is blank, then I want to echo it.

 

In the example below:

 

9500 is incorrect

 

9503 only has 1 row but is ok

 

the rest may have 2 or more rows but as long as 1 row has PayPal in it, then it is ok.

 

How can I loop through an array but then delete everything from the array with that ID, and then carry on looping through the array again?

 

 

9511 3 PayPal IPN Verified [Completed (Verified; £24.99)]

9511 3

9508 3 PayPal IPN Verified [Completed (Unverified; £3.99)]

9508 3

9507 3 PayPal IPN Verified [Completed (Unverified; £1.99)]

9507 3

9506 3 PayPal IPN Verified [Completed (Verified; £9.49)]

9505 3 PayPal IPN Verified [Completed (Verified; £9.49)]

9501 3 PayPal IPN Verified [Completed (Unverified; £7.99)]

Use a couple of foreach() loops and unset().  If you want a better answer provide more details such as how that data is structured in your code and/or where it comes from (db tables/structure).
