How can PHP developers efficiently troubleshoot and debug string manipulation issues in their code?

To efficiently troubleshoot and debug string manipulation issues in PHP code, developers can use built-in functions like var_dump(), print_r(), and echo to inspect the contents of variables at different stages of the code execution. They can also use string manipulation functions like strpos(), substr(), and str_replace() to isolate and manipulate specific parts of the string. Additionally, using error_reporting(E_ALL) and ini_set('display_errors', 1) can help identify any syntax errors or warnings that may be affecting the string manipulation process. 

<?php

// Example code snippet to troubleshoot and debug string manipulation issues
$string = "Hello, World!";
var_dump($string);

$new_string = str_replace("Hello", "Hi", $string);
echo $new_string;

?>
