[PHP] Condition for array with string as keys
- by Kel
My PL/SQL procedure returns a cursor. It always returns data. I fetch (oci_fetch_assoc) it and save it in an array. If results were found the keys of the array will be strings. If the cursor didn't find data, it will return value 0, thus the key of the array will be numeric.
while($data = oci_fetch_assoc($cursor)){
if(!isset($data[0])){
...
}
...
...
}
What's the best way to check that the array is not just 0, but contains data?
Thanks
