How does one create an array?

[leuce]

G'day everyone

Sorry for the silly question, but how does one create an array in which the [0] item shows the number of items in the array?

I know that when I use StringSplit, the [0] item is the number of items in the array, but when I create an array using e.g. "Local $foo[10]", then the [0] item is not the number of items in the array, but is in fact the first item in the array.

Alternatively, how can I find out what the number of items are in an array that was created using e.g. "Local $foo[10]" to which I had added more items in the array? Is this simple or complex?

Thanks

Hello leuce,

When creating your own arrays, and you want the number of items to show in $array[0] you will need to set it manually. If it contains the first item in your array, then you will need to change how you add the items so it starts at [1] rather than [0] or you will be overwriting the first element of your array when setting the array count number.

Ubound($array) will return the size of $array. this will count [0] as an item too. So if you want just the items from [1] to [10] you would manually create your count with this example below:

$array[0] = Ubound($array)-1

Personally I like my arrays to just contain the useful data, and when I find a need to check the array size, I call it with Ubound(), and assign it to a variable if need be.

Hope this Helps.

Thanks, that was a useful answer.

My Pleasure!

I noticed your using StringSplit and if you find it to be more useful to just have the data in your arrays, StringSplit has an option to start at [0] rather than [1] with an element count in [0].

StringSplit($myString, '|',2)

adding a 2 in your third parameter of StringSplit will return your array without the element count, starting the first element at [0] of your array.
