An array stores multiple values in one single variable.
A variable is a storage area holding a number or text. The problem is, a variable will hold only
An array is a special variable, which can store multiple values in one single variable.
If you have a list of items (a list of car names, for example), storing the players in single
variables could look like this:
However, what if you want to loop through the players and find a specific one? And what if you
had not 3 players, but 300?
The best solution here is to use an array
An array can hold all your variable values under a single name. And you can access the values by
referring to the array name.
Each element in the array has its own index so that it can be easily accessed.
In PHP, there are three kind of arrays:
A numeric array stores each array element with a numeric index.
There are two methods to create a numeric array.
1. In the following example the index are automatically assigned (the index starts at 0):
2. In the following example we assign the index manually:
In the following example you access the variable values by referring to the array name and
The code above will output:
An associative array, each ID key is associated with a value.
When storing data about specific named values, a numerical array is not always the best way to do
With associative arrays we can use the values as keys and assign values to them.
In this example we use an array to assign ages to the different persons:
This example is the same as Example, but shows a different way of creating the array:
The ID keys can be used in a script:
In a multidimensional array, each element in the main array can also be an array. And each
element in the sub-array can be an array, and so on.
In this example we create a multidimensional array, with automatically assigned ID keys:
The array above would look like this if written to the output:
Lets try displaying a single value from the array above:
