How does PHP handle array size dynamically?

PHP handles array size dynamically by allowing arrays to grow or shrink as needed without specifying a fixed size. This means that you can add or remove elements from an array without worrying about resizing it manually. PHP automatically manages the memory allocation for arrays based on the number of elements they contain. 

// Dynamically resizing an array in PHP
$dynamicArray = [];
$dynamicArray[] = "Element 1";
$dynamicArray[] = "Element 2";
$dynamicArray[] = "Element 3";

print_r($dynamicArray);
