What is the best method to append elements to an array in PHP during each iteration of a loop?

When appending elements to an array in PHP during each iteration of a loop, the most efficient method is to use the [] shorthand syntax to directly append the element to the array. This method avoids unnecessary function calls like array_push() and is more concise. 

<?php

// Initialize an empty array
$array = [];

// Loop through elements and append them to the array
for ($i = 0; $i < 5; $i++) {
    $array[] = $i;
}

// Print the resulting array
print_r($array);

?>
