Adding Elements to an Array

Using [ ] Syntax:

You can add elements to an array by assigning values to new or existing keys using square brackets [ ].

$array = []; // Initialize an empty array
$array[] = "element1"; // Add "element1" to the end of the array
$array[] = "element2"; // Add "element2" to the end of the array

Using array_push( ) Function:

PHP array_push() appends one or more elements to the end of an array.

$array = [ ]; // Initialize an empty array
array_push($array, "element1", "element2"); 

// Add "element1" and "element2" to the end of the array

Adding and removing elements from arrays in PHP can be achieved using various built-in functions and array manipulation techniques.
