What is the significance of the "as" keyword in the context of a foreach loop in PHP, as discussed in the thread?

The "as" keyword in a foreach loop in PHP is used to assign the current value of the array element to a variable for easier access within the loop. It allows you to iterate over each element of an array and perform operations on them without directly accessing the array itself. This keyword provides a cleaner and more readable way to work with arrays in PHP. 

// Example of using the "as" keyword in a foreach loop
$numbers = [1, 2, 3, 4, 5];

foreach ($numbers as $number) {
    echo $number . "<br>";
}
