Are there any specific debugging techniques that can be recommended for identifying errors in PHP code, such as the one provided in the forum thread?

Issue: One common debugging technique for identifying errors in PHP code is to use the var_dump() function to display the contents of variables and arrays at specific points in your code. This can help you see the values being assigned to variables and track down any unexpected behavior. Fix:

// Debugging using var_dump()
$variable = "Hello, world!";
var_dump($variable);
