How Can I Access Array Elements Returned by a Function in PHP?

Accessing Function-Returned Arrays in PHP

Consider the scenario where you have a template engine that injects code based on your specified locations. To test for a particular condition, you've created a function:

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

However, the private nature of $this->data presents a challenge, making it inaccessible from certain contexts.

To resolve this, getData() is typically employed, but it doesn't work in this case. The following approach also fails:

$this->getData()['a']['b']

Additionally, assigning the value to a variable doesn't provide a viable solution.

Solution

PHP 5.4 and above offer a direct approach:

getSomeArray()[2]

For PHP 5.3 or earlier, a temporary variable can be used:

$temp = getSomeArray();
$temp[2]

This method allows you to access the array elements returned by the function without encountering the limitations imposed by the private nature of the array.
