What is the difference between using a for loop and a foreach loop in PHP when iterating through arrays?

When iterating through arrays in PHP, the main difference between using a for loop and a foreach loop is in the syntax and ease of use. A foreach loop is specifically designed for iterating through arrays and provides a more concise and readable way to access array elements without needing to manually manage the iteration index. On the other hand, a for loop gives you more control over the iteration process, allowing you to define custom iteration logic and conditions. 

// Using a foreach loop to iterate through an array
$colors = array("red", "green", "blue");
foreach ($colors as $color) {
    echo $color . "<br>";
}

// Using a for loop to iterate through an array
$colors = array("red", "green", "blue");
$length = count($colors);
for ($i = 0; $i < $length; $i++) {
    echo $colors[$i] . "<br>";
}
