How can the echo command be used to address specific issues in PHP code?

If you need to debug or troubleshoot specific issues in your PHP code, you can use the `echo` command to print out variables, messages, or any other information to the screen. This can help you identify where the problem lies and track the flow of your code. Example PHP code snippet: 

// Issue: Need to check the value of a variable
$number = 10;
echo $number; // Output: 10

// Issue: Debugging a specific section of code
echo "Debugging point A";

// Issue: Checking if a condition is met
if ($number > 5) {
    echo "Number is greater than 5";
} else {
    echo "Number is less than or equal to 5";
}
