how do i delete keys from an array if it has no values? eg, this:
what does the value have to do with it??? other than that you want to remove items where the value is 'empty'.
also 'no value' is vague, do you mean an empty string or do you mean NULL?

try the array_values() function, possibly in conjunction with
array_unique() depending on your requirements. look them up in the manual, while your there read the rest of it as well.

I assume you know how to:
1. create an array 2. loop an array 3. check a variable's value is/isn't something in particular 4. assign a value to a variable.
combine these skills! (if you can answer no to any of the above questions then you need to read the manual - its a good manual, people have spent countless hours writing - show respect and use it!)
