How Can I Access an Array Returned by a PHP Function, Especially in Older PHP Versions?

Accessing Array Returned by a Function in PHP

When utilizing a template engine that injects code dynamically, maintaining access to private data within functions can pose a challenge. Consider the following code snippet:

myfunction() { return '($this->data["a"]["b"] ? true : false)'; }

Here, the $this->data property is private and cannot be accessed directly from the public function. Assigning the property's value to a temporary variable doesn't solve the issue if the value is intended for immediate use in an if block.

Solution:

In PHP versions 5.4 and later, you can directly access the returned array by using square brackets:

getSomeArray()[2]

This approach eliminates the need for temporary variables and allows you to access array elements seamlessly.

However, if you're using PHP 5.3 or earlier, you still need to assign the returned array to a variable first:

$arr = getSomeArray();
echo $arr[2];
