What is the best approach for incrementing values in a series of strings in PHP?

When incrementing values in a series of strings in PHP, the best approach is to use a combination of regular expressions and the preg_replace_callback function. This allows you to match the numbers in the strings and increment them accordingly. By using a callback function, you can perform the increment operation on each matched number. This approach ensures that only the numbers are modified while leaving the rest of the string intact. 

$strings = ['item1', 'item2', 'item3'];

$incrementedStrings = array_map(function($string) {
    return preg_replace_callback('/\d+/', function($match) {
        return $match[0] + 1;
    }, $string);
}, $strings);

print_r($incrementedStrings);
