12,328 PointsDeclaring Array
At around 1.11 of the video it was mention that it is good practice to declare an empty array first than assign values to it, so instead of making an array like this:
$something = array(
"value",
"value",
"value"
);
you do it like this:
$something = array();
$something[] = "value";
$something[] = "value";
$something[] = "value";
But why is that? isn´t its easier to understand the first way?

Im guessing they are showing another way to do it & showing how it works in a "push" function so that you can see that you can add a value to the end of the array without keeping track of where it goes in the list. For example, if you already have 3 items in the array, you can add 3 more items doing the 2nd way without using indexes. Another reason for doing it the 2nd way is you may not know all your values up front. If an array is used for storing errors, you want to push those values on as you receive them & not have to worry about the index of where to add the value.
