How can a PHP beginner effectively debug and troubleshoot issues with variable values in their code?

To effectively debug and troubleshoot issues with variable values in PHP, beginners can use functions like var_dump() or print_r() to output the values of variables at different points in the code. This can help identify where the values are changing unexpectedly. Additionally, using die() or exit() statements can help stop the code execution at a specific point to inspect variable values. 

// Example code snippet demonstrating the use of var_dump() to debug variable values
$number = 10;
var_dump($number); // Output: int(10)

// Example code snippet demonstrating the use of print_r() to troubleshoot variable values
$array = [1, 2, 3];
print_r($array); // Output: Array ( [0] => 1 [1] => 2 [2] => 3 )
