What are some common debugging techniques for PHP code that is not displaying expected values on a webpage?

One common debugging technique for PHP code that is not displaying expected values on a webpage is to use the `var_dump()` function to inspect the variables and their values at various points in the code. This can help identify any unexpected values or errors in the logic. Additionally, checking for syntax errors, ensuring proper variable scope, and verifying that the correct data is being passed to functions can also help troubleshoot the issue. 

<?php
// Example code snippet demonstrating the use of var_dump() for debugging
$variable = 10;

// Check the value of the variable using var_dump()
var_dump($variable);

// Other debugging techniques can be used here to identify and fix the issue
?>
