How can the PHP error logs and web server logs be utilized to troubleshoot issues with code execution?

When troubleshooting code execution issues, PHP error logs and web server logs can provide valuable information about errors or warnings that occurred during script execution. By reviewing these logs, developers can identify the root cause of the issue and make necessary adjustments to their code. 

```php
// Enable error logging in PHP
ini_set('display_errors', 0);
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Sample code snippet that may generate an error
$undefinedVariable = 'Hello, World!';
echo $definedVariable;
```

In the above code snippet, we have enabled error logging in PHP and set the path to the error log file. We then intentionally created an error by trying to echo a variable that was not defined. By reviewing the error log, we can see that the issue is caused by referencing an undefined variable, allowing us to fix the problem by either defining the variable or removing the reference to it.
