What potential pitfalls should be considered when using array_push in PHP to modify arrays?

One potential pitfall when using array_push in PHP to modify arrays is that it can only add elements to the end of the array, which may not always be the desired behavior. To address this, you can use the array_unshift function to add elements to the beginning of an array instead.

// Using array_unshift to add elements to the beginning of an array
$myArray = [1, 2, 3];
array_unshift($myArray, 0); // Adds 0 to the beginning of the array
print_r($myArray); // Output: [0, 1, 2, 3]
