How can debugging techniques be effectively utilized to identify and resolve issues in PHP code, as suggested in the thread?

To effectively utilize debugging techniques to identify and resolve issues in PHP code, developers can use tools like Xdebug to step through the code line by line, inspect variables, and track the flow of execution. By setting breakpoints and watching variable values, developers can pinpoint the exact location of bugs and understand the underlying issues causing them. Additionally, logging functions like error_log() can be used to output specific messages or variable values for further analysis. 

// Example PHP code snippet utilizing debugging techniques to identify and resolve issues
<?php

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Use Xdebug to step through the code and inspect variables
$x = 10;
$y = 0;

// Divide by zero error
$z = $x / $y;

// Use error_log() to log specific messages or variable values
error_log("Division result: " . $z);

?>
