How can PHP developers ensure that their code is optimized when working with arrays in loops?

To optimize code when working with arrays in loops, PHP developers can use functions like `count()` to get the array length outside the loop rather than calling it on each iteration. Additionally, they can store the array length in a variable to avoid repeated calculations. This can improve performance by reducing unnecessary computations within the loop. 

// Example of optimizing code when working with arrays in loops
$myArray = [1, 2, 3, 4, 5];
$arrayLength = count($myArray);

for ($i = 0; $i < $arrayLength; $i++) {
    echo $myArray[$i] . "\n";
}
