How can you ensure that when replacing field names in PHP arrays, you are also replacing the field names themselves?

When replacing field names in PHP arrays, it's important to ensure that you are also updating the field names themselves, not just the values associated with those fields. One way to achieve this is by using the array_combine() function to create a new array with the updated field names and values. 

// Original array with field names to be replaced
$originalArray = array(
    'old_field1' => 'value1',
    'old_field2' => 'value2',
);

// Array mapping old field names to new field names
$fieldMapping = array(
    'old_field1' => 'new_field1',
    'old_field2' => 'new_field2',
);

// Create a new array with updated field names
$newArray = array_combine(array_values($fieldMapping), array_values($originalArray));

print_r($newArray);
