converting for loop to foreach-CodePudding

How can we convert this kind of for loop to foreach loop in php?

$integerPartOfAverage = 4;
for($counter = 0; $counter < $integerPartOfAverage;   $counter) {
    $stars[] = 'Yellow';
}

This does not really make sense. The only sense of that loop is to repeat the array assignment 4 times. That is what a for loop is for. A foreach loop is for something else, it is to loop over something that can be iterated over.

Instead what you could do is get rid of the loop completely and directly setup the target array:

<?php
$stars = array_fill(0, 4, 'Yellow');
print_r($stars);

The output is exactly the same as what your loop creates:

Array
(
    [0] => Yellow
    [1] => Yellow
    [2] => Yellow
    [3] => Yellow
)

Here is an example of how you could convert the for loop in your code to a foreach loop in PHP:

// Set the initial value for the array of stars
$stars = array();

// Use a foreach loop to iterate over the range of integers from 0 to $integerPartOfAverage
foreach(range(0, $integerPartOfAverage) as $counter) {
    // Add a Yellow element to the array of stars
    $stars[] = 'Yellow';
}

In this example, the foreach loop is used to iterate over a range of integers from 0 to $integerPartOfAverage. For each integer in the range, the loop will add a new element to the $stars array with the value 'Yellow'.

This code is equivalent to the original for loop, but it uses the foreach loop construct instead. The foreach loop is often preferred in PHP because it is more concise and easier to read than a traditional for loop.
