How can PHP developers ensure proper syntax and structure when using control structures like foreach and while loops with arrays?

To ensure proper syntax and structure when using control structures like foreach and while loops with arrays in PHP, developers should pay close attention to the opening and closing braces, as well as the correct usage of semicolons and parentheses. It is essential to properly initialize variables before using them in loops and to use descriptive variable names to enhance readability. 

// Example of using foreach loop with an array
$fruits = array("apple", "banana", "orange");
foreach ($fruits as $fruit) {
    echo $fruit . "<br>";
}

// Example of using while loop with an array
$numbers = array(1, 2, 3, 4, 5);
$i = 0;
while ($i < count($numbers)) {
    echo $numbers[$i] . "<br>";
    $i++;
}
