What is the difference between using square brackets and parentheses to access array values in PHP?

In PHP, square brackets [] are used to access array values by index, while parentheses () are used to call functions. If you try to access array values using parentheses, PHP will interpret it as a function call instead of an array access, leading to a syntax error. To correctly access array values, make sure to use square brackets. 

// Incorrect way to access array value
$array = [1, 2, 3];
$value = $array(0); // Syntax error

// Correct way to access array value
$array = [1, 2, 3];
$value = $array[0]; // Accessing the first element of the array
