How can I output an entire array in PHP without just getting the word "Array"?

When you try to output an entire array in PHP using echo or print, you will often just see the word "Array" displayed on the screen. To properly display the contents of an array, you can use the print_r() or var_dump() functions. These functions will show the structure and values of the array in a readable format. 

$array = [1, 2, 3, 4, 5];
print_r($array); // Output the array using print_r()
echo "<br>";
var_dump($array); // Output the array using var_dump()
