Create array with offset?

[SaranacLake]

First off, what are the names for the types of arrays?

What do you call an array that uses integers for the key?

I think when the key is text it is called an associative array?

Anyways...

 

Is there a way to create an array where they keys are integers, but you are defining the first entry?

I would like my array to either start with a "1" or maybe "1001".

How do I do that?

In PHP, it's basically either associative or not.

An array. Sometimes "list".

Not just string. Associative is when the keys have some sort of particular meaning. You could have an associative array for weekday names. You could also have a non-associative ("list") array for weekday names. And they could even be the same thing. What matters is how the array is used.

Yes: by creating an array where you define the first entry.

But I'm not sure of how to do that,

I create my array in a llop...

	while(($file = readdir($handle)) != FALSE){
	     $photoFiles[] = $file;
	}
	

 

If I was doing this out of a loop I guess my first entry could be...

$photoFiles[1001] = something;

 

But how do I do that in the loop and not have everything be $photoFiles[1001] ?

You can use a variable there: $photoFiles[$i] = $file; That variable $i can be initialised and incremented.
