What debugging techniques can be employed to troubleshoot path problems in PHP?

Path problems in PHP can often be resolved by using debugging techniques such as checking file permissions, verifying file paths, and using error logging to identify any issues. Additionally, using functions like realpath() can help resolve any inconsistencies in file paths. 

// Example code snippet to troubleshoot path problems in PHP
$path = 'path/to/file.txt';

// Check if file exists
if (file_exists($path)) {
    // Get the absolute path
    $absolute_path = realpath($path);
    
    // Output the absolute path
    echo "Absolute path: " . $absolute_path;
} else {
    // Log an error if the file does not exist
    error_log("File does not exist: " . $path);
}
