Using PHP array_push to Add Elements to an Array

In PHP, arrays are a powerful data structure for storing multiple values of the same type, and the built-in array_push function provides a convenient way to add new elements to the end of an array.

The array_push function accepts the target array as its first argument and one or more elements to be appended as subsequent arguments, returning the new length of the array after insertion.

Example of adding a single element:

$fruits = array("apple", "banana", "orange");
$length = array_push($fruits, "pear");
echo "New array length: " . $length . "\n";
print_r($fruits);

Running this code outputs a length of 4 and shows the array now contains "apple", "banana", "orange", and "pear".

Example of adding multiple elements at once:

$colors = array("red", "blue");
$length = array_push($colors, "yellow", "green");
echo "New array length: " . $length . "\n";
print_r($colors);

This second example also results in a length of 4, with the array now holding "red", "blue", "yellow", and "green".

In summary, the PHP array_push function offers a simple and efficient method for appending one or several elements to an array, helping developers manage array data more flexibly and improve code readability.
