Condition for array with string as keys

My开发者_开发知识库 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

Here is my solution:

if($data != array(0 => "0")){

and it works

if(!empty($data[0])) { ... }

oci_fetch_assoc returns an associated array, that is the column names are indexes in the array.

try one of these:

($data['firstColumn'] === 0)
(reset($data) === 0)

where 'firstColumn' is the actual name of the first column

You can use the '===' to see if $data[0] equals 0. Like:

if($data[0]===0) {
   // It really is the number 0
}
