How does using a comma affect the output when accessing array elements in PHP, as demonstrated in the code example?

Using a comma when accessing array elements in PHP will result in a syntax error because the correct way to access array elements is by using square brackets. To fix this issue, simply replace the comma with square brackets to access the desired element in the array. 

// Incorrect way using a comma
$array = [1, 2, 3];
echo $array(1); // This will cause a syntax error

// Correct way using square brackets
$array = [1, 2, 3];
echo $array[1]; // This will output 2
