What are the best practices for manipulating arrays in PHP to avoid overwriting values?

When manipulating arrays in PHP, it is important to avoid overwriting values by being mindful of array keys and ensuring unique keys are used. One way to prevent overwriting values is to use the array_push() function to add elements to the end of an array without specifying keys. Additionally, using functions like array_merge() or array_merge_recursive() can help combine arrays without overwriting existing values. 

// Example of using array_push to add elements to an array without overwriting values
$myArray = ['a' => 1, 'b' => 2];
array_push($myArray, 3);
print_r($myArray);
