Looping array using each() and foreach() loop

 Looping array using each() and foreach() loop

In PHP, you can loop through an array using `foreach()` and `each()` loops. Here's how you can use both:

### Using `foreach()` Loop:

The `foreach()` loop is a convenient way to iterate over arrays. Here's an example:

```php

<?php

// Sample array

$colors = array("Red", "Green", "Blue", "Yellow");

// Loop through the array using foreach

foreach ($colors as $color) {

    echo $color . "<br>";

}

?>

```

In this example, `foreach($colors as $color)` iterates through each element in the `$colors` array and assigns the current element's value to the variable `$color`. It then echoes each color followed by a line break.

### Using `each()` Function:

The `each()` function returns the current key-value pair from an array and advances the array cursor. Here's an example of using `each()`:

```php

<?php

// Sample array

$colors = array("Red", "Green", "Blue", "Yellow");

// Reset the array pointer

reset($colors);

// Loop through the array using each() function

while ($element = each($colors)) {

    echo "Key: " . $element['key'] . ", Value: " . $element['value'] . "<br>";

}

?>

```

In this example, the `each()` function is used within a `while` loop. It returns an array with 'key' and 'value' indices for the current element. The `reset($colors)` function is used to ensure that the array pointer is at the beginning of the array before using `each()`.

Both methods achieve similar results, but `foreach()` is more commonly used for iterating through arrays in PHP due to its simplicity and readability.
