How can PHP developers optimize their code by utilizing built-in array functions like array_push() and trim() effectively?

PHP developers can optimize their code by utilizing built-in array functions like array_push() to efficiently add elements to an array without having to manually manage array indexes. They can also use functions like trim() to remove whitespace from the beginning and end of strings, which can help improve data consistency and reduce unnecessary characters in the code. 

// Example of using array_push() to add elements to an array
$fruits = ['apple', 'banana', 'orange'];
array_push($fruits, 'kiwi', 'mango');

// Example of using trim() to remove whitespace from a string
$name = '   John Doe   ';
$trimmedName = trim($name);
