How can PHP be used to separate words and numbers in a string?

To separate words and numbers in a string using PHP, you can use a combination of regular expressions and built-in functions like preg_match_all. By defining separate patterns for words and numbers, you can extract them from the input string and store them in separate arrays or variables for further processing. 

$inputString = "Hello123World456";
preg_match_all('/[a-zA-Z]+|\d+/', $inputString, $matches);
$words = $matches[0];
$numbers = array_filter($matches[0], 'is_numeric');

print_r($words); // Output: Array ( [0] => Hello [1] => World )
print_r($numbers); // Output: Array ( [0] => 123 [1] => 456 )
