What are the advantages and disadvantages of using the array_combine function in PHP to create key-value pairs from two strings?

When creating key-value pairs from two strings in PHP, the array_combine function can be used to easily combine them into an associative array. The advantage of using array_combine is that it is a built-in function that simplifies the process of creating key-value pairs. However, one disadvantage is that both input arrays must have the same number of elements, otherwise an error will occur. 

// Two strings to combine into key-value pairs
$keys = "name, age, city";
$values = "John, 25, New York";

// Convert strings to arrays
$keysArray = explode(", ", $keys);
$valuesArray = explode(", ", $values);

// Combine arrays into associative array
$combinedArray = array_combine($keysArray, $valuesArray);

// Output the resulting array
print_r($combinedArray);
