How can syntax errors like unexpected '[' be avoided when trying to access array elements in PHP?

To avoid syntax errors like unexpected '[' when trying to access array elements in PHP, make sure to use the correct syntax for accessing array elements. In PHP, array elements are accessed using square brackets [], not curly braces {}. Double-check your code to ensure that you are using the correct syntax to access array elements.

// Incorrect way to access array element
$array = [1, 2, 3];
echo $array{0}; // Incorrect syntax using curly braces

// Correct way to access array element
$array = [1, 2, 3];
echo $array[0]; // Correct syntax using square brackets
