What does the error "Illegal string offset" mean in PHP and how can it be resolved?

The error "Illegal string offset" in PHP occurs when trying to access an index of a string as if it were an array. To resolve this issue, make sure that you are working with an actual array and not a string. Check the data type being used and ensure that you are accessing array elements correctly. 

// Incorrect way of accessing a string as an array
$string = "Hello";
echo $string[0]; // This will throw an "Illegal string offset" error

// Correct way of accessing an array element
$array = ["H", "e", "l", "l", "o"];
echo $array[0]; // This will correctly output "H"
