PHP Array Operator

In this chapter you will learn:

You can create and manage arrays using square brackets []. [] can both create arrays and add elements to the end of an array.

Array operator has the following syntax.

$arratName[] = "new Value";

$arratName[index] = "new Value";

$arratName["key"] = "new Value";

$arratName[index]; // get value by index

$arratName["key"]; // get value by key

The following code uses the array operator to create and indexed array.


<?PHP/* j  a  v a 2 s  . c  o  m*/
$array[] = "Foo"; 
$array[] = "Bar"; 
$array[] = "java2s.com"; 
var_dump($array); 
?>

The code above generates the following result.

For non-default indices, we can place our key inside the square brackets, like this:


<?PHP/*from   j  a v  a  2s .  c o m*/
$array["a"] = "Foo"; 
$array["b"] = "Bar"; 
$array["c"] = "Baz"; 
var_dump($array); 
?>

The code above generates the following result.
