Is it a common issue for the $from parameter to be ignored when merging associative arrays in PHP?

When merging associative arrays in PHP using the `array_merge()` function, the `$from` parameter is ignored because it is not a valid parameter for this function. To merge associative arrays while specifying the order of merging, you can use the `+` operator, which combines the arrays while preserving the keys from the first array. 

// Define two associative arrays
$array1 = ['a' => 1, 'b' => 2];
$array2 = ['b' => 3, 'c' => 4];

// Merge arrays while preserving keys from the first array
$result = $array1 + $array2;

// Output the merged array
print_r($result);
