How can PHP beginners effectively troubleshoot issues with variable output in PHP scripts?

When troubleshooting variable output issues in PHP scripts, beginners can start by checking for syntax errors, ensuring proper variable initialization, and using print_r() or var_dump() functions to inspect variable values. Additionally, using echo statements to display intermediate results can help identify where the issue lies. 

// Example PHP code snippet to troubleshoot variable output
$variable = "Hello, World!";

// Check for syntax errors
if (isset($variable)) {
    // Ensure proper variable initialization
    echo $variable;
} else {
    echo "Variable is not set.";
}

// Use print_r() or var_dump() functions to inspect variable values
print_r($variable);
var_dump($variable);
