How can PHP developers effectively troubleshoot and debug code that is not outputting expected results?

To troubleshoot and debug PHP code that is not outputting expected results, developers can start by checking for syntax errors, using print statements to display variable values, and utilizing debugging tools like Xdebug. Additionally, reviewing error logs and stepping through the code line by line can help identify the root cause of the issue. 

<?php
// Example code snippet for troubleshooting PHP code
$variable = 10;

// Check for syntax errors
if ($variable == 10) {
    // Use print statements to display variable values
    echo "Variable is equal to 10";
} else {
    echo "Variable is not equal to 10";
}

// Utilize Xdebug or other debugging tools
// Review error logs and step through the code to identify issues
?>
