How can PHP developers efficiently troubleshoot and debug issues with string manipulation functions?

To efficiently troubleshoot and debug issues with string manipulation functions in PHP, developers can use functions like `var_dump()` or `print_r()` to inspect the output of the variables at various stages of the code execution. Additionally, using `echo` or `die()` statements strategically can help pinpoint where the issue may lie in the code. Lastly, utilizing PHP's built-in error reporting functions like `error_reporting()` and `ini_set('display_errors', 1)` can provide more detailed information about any errors that occur during string manipulation. 

<?php
// Example code snippet for troubleshooting string manipulation issues
$string = "Hello, World!";
$new_string = str_replace("Hello", "Hi", $string);

// Debugging output
var_dump($new_string);
print_r($new_string);
echo $new_string;
die();
?>
