How can you ensure the correct syntax when accessing array elements in PHP?

When accessing array elements in PHP, it is important to ensure the correct syntax to avoid errors. To access array elements, you need to use square brackets `[]` with the index of the element you want to access inside them. It is crucial to make sure that the index you provide is within the bounds of the array to prevent "Undefined offset" errors.

// Example of accessing array elements with correct syntax
$colors = array("red", "green", "blue");
echo $colors[1]; // This will output "green"
