How can you modify fscanf parameters to capture specific types of characters or content in PHP?

To capture specific types of characters or content using fscanf in PHP, you can modify the format parameter to specify the type of content you want to capture. For example, if you want to capture only numbers, you can use '%d' in the format parameter. If you want to capture strings, you can use '%s'. By specifying the correct format parameter, you can ensure that fscanf captures the desired content accurately. 

$handle = fopen("input.txt", "r");
fscanf($handle, "%d %s", $number, $string);
fclose($handle);

echo "Number: $number, String: $string";
