Array Empty Function

[funch27]

Is there a function you can use that will return if an array is empty or not?

[neuromancer]

if(count($target_array)==0) {
 #Empty
} else {
 #Elements
}

Well, here's a couple that are useful:

sizeof(array); // Returns number of elements in specified array. Also use count(array);

in_array(value, array); // Returns if you specified value is in the array.

I couldn't find one that specifically finds if it is empty or not, but you could do something like:

$arraycount = sizeof($myarray);

if ($arraycount != 0) {
// do somestuff }
else {
// do some other stuff }

...if that's what you are looking for.

Looking for a similar function in Visual Basic I concocted the following function

Function ArrayDimensioned(Test As Variant) As Boolean
On Error GoTo ArrayDimensionedError
Tmp = UBound(Test)
If IsNumeric(Tmp) Then
ArrayDimensioned = True
' MsgBox "Dimensioned " & Tmp
End If
ArrayDimensionedError:
On Error GoTo 0
End Function

and tested it with :

Dim MyArray() as string

Sub Test()
Dimp Tmp as Boolean
Tmp = ArrayDimensioned(MyArray)
ReDim Preserve MyArray(0)
Tmp = ArrayDimensioned(MyArray)

End Sub

I trust this helps ...
