How can arrays in PHP be combined without errors when one array is missing a value?

When combining arrays in PHP, if one array is missing a value that the other array contains, it can lead to errors such as notices or warnings. To avoid these errors, you can use the array_merge function to merge the arrays. This function will combine the arrays without any issues, even if one array is missing a value that the other array has. 

$array1 = ['a' => 1, 'b' => 2];
$array2 = ['a' => 3, 'c' => 4];

$combinedArray = array_merge($array1, $array2);

print_r($combinedArray);
