What is the difference between constructing an array as a string versus as an actual array in PHP, and how does this affect the interpretation by the PHP parser?

Constructing an array as a string in PHP is simply creating a string that looks like an array, but it is not actually an array. This can lead to issues when trying to access or manipulate the data as if it were an array. To correctly construct an array in PHP, you should use square brackets [] to define the array elements. 

// Incorrect way: constructing an array as a string
$arrayAsString = "[1, 2, 3]";

// Correct way: constructing an actual array
$array = [1, 2, 3];
