Question

I was trying to convert basic Javascript function into PHP, and I saw that one of the variables was declared var Variable = new Array (13).

I know that PHP variables are declared like: $variable = array()

but what about the “13” in new Array(13)? does that translate to $variable = array(13)? I’ve tried that but it didn’t seem to work.

This in Javascript

var results = new Array (13);

becomes this in PHP, am I correct?

$results = array(13);

Actually, in this context, you’re creating an array of size 13.

You don’t really need to preallocate arrays in PHP, but you can do something like:

$result = array_fill( 0, 12, null);

This will create an array with 13 elements (indexes 0 through 12) whose values are null.
