How can PHP beginners improve their code quality by utilizing functions like count() and foreach()?

PHP beginners can improve their code quality by utilizing functions like count() and foreach() to efficiently iterate over arrays. By using count() to get the length of an array, beginners can avoid hardcoding array sizes and potential errors. Using foreach() allows beginners to easily loop through array elements without worrying about array indexes.

// Example code snippet using count() and foreach() to iterate over an array
$numbers = [1, 2, 3, 4, 5];

// Using count() to get the length of the array
$length = count($numbers);

// Using foreach() to loop through the array elements
foreach ($numbers as $number) {
    echo $number . " ";
}
