Are there any potential pitfalls in directly assigning values to arrays without initializing them first in PHP?

Assigning values to arrays without initializing them first in PHP can lead to unexpected results and errors. It is best practice to initialize an array before assigning values to it to avoid any potential pitfalls. To solve this issue, you can simply initialize the array using empty square brackets before assigning values to it. 

// Initialize an empty array before assigning values
$array = [];

// Assign values to the array
$array[] = "value1";
$array[] = "value2";
$array[] = "value3";

// Print the array to see the values
print_r($array);
