How can PHP developers efficiently troubleshoot and debug issues related to string manipulation using regular expressions?

When troubleshooting and debugging issues related to string manipulation using regular expressions in PHP, developers can use functions like preg_match() and preg_replace() to test and manipulate the strings. By using these functions along with proper error handling and debugging techniques, developers can efficiently identify and fix issues with regular expressions in their code. 

// Example code snippet to troubleshoot and debug string manipulation using regular expressions in PHP

if (preg_match('/Hello/', $string)) {
    echo "String contains 'Hello'";
} else {
    echo "String does not contain 'Hello'";
}

// Using preg_replace to replace a specific pattern in the string
$newString = preg_replace('/World/', 'Universe', $string);
