In what ways can PHP developers efficiently troubleshoot and resolve issues related to string manipulation errors, like removing the second period in a string in the provided context?

To efficiently troubleshoot and resolve issues related to string manipulation errors, such as removing the second period in a string, PHP developers can use string manipulation functions like strpos() to find the position of the first period and then substr_replace() to replace the second period with an empty string. 

$string = "This is a string with.. multiple periods.";
$first_period_position = strpos($string, '.');
$second_period_position = strpos($string, '.', $first_period_position + 1);

if ($second_period_position !== false) {
    $string = substr_replace($string, '', $second_period_position, 1);
}

echo $string;
