How Do I Access an Array Returned by a PHP Function?

Accessing a Function's Array Return Value in PHP

The task of accessing an array returned by a function in PHP can pose a challenge, especially when working with private properties or template engines that insert code conditionally.

In such scenarios, consider the following solutions:

PHP 5.4 and Later

PHP 5.4 introduced a more concise syntax for accessing array elements returned by functions:

$value = getSomeArray()[2]

This simplified syntax allows you to directly access the array index without assigning the value to a temporary variable.

PHP 5.3 and Earlier

For PHP versions prior to 5.4, you will need to use a temporary variable to access the array element:

$array = getSomeArray();
$value = $array[2];

This technique ensures that you can work with the array even when the function returns it as a private property.

Additionally, you can reference the PHP documentation (https://secure.php.net/manual/en/language.types.array.php#example-62) for further details on array indexing and functionality.
