How can you effectively debug PHP code to troubleshoot issues like variables not being concatenated properly?

To effectively debug PHP code for issues like variables not being concatenated properly, you can use functions like var_dump() or echo statements to check the values of the variables at different points in your code. Make sure to also check for any syntax errors or typos in your concatenation statements. Additionally, using an IDE with debugging capabilities can help you step through your code and identify where the issue is occurring. 

// Example code snippet to demonstrate proper variable concatenation in PHP
$first_name = "John";
$last_name = "Doe";

// Incorrect way of concatenating variables
$full_name = $first_name + " " + $last_name;

// Correct way of concatenating variables using dot (.)
$full_name = $first_name . " " . $last_name;

echo $full_name; // Output: John Doe
