How can PHP developers efficiently troubleshoot and debug issues related to reading and processing text files?

When troubleshooting issues related to reading and processing text files in PHP, developers can efficiently debug by checking for common errors such as incorrect file paths, file permissions, or encoding mismatches. They can also use functions like file_exists() and is_readable() to verify the file's existence and readability before attempting to read it. Additionally, using error handling techniques like try-catch blocks or error_log() can help identify and log any errors encountered during file processing. 

$file = 'example.txt';

if (file_exists($file) && is_readable($file)) {
    $contents = file_get_contents($file);
    
    // Process the file contents here
    
    echo $contents;
} else {
    echo 'Error: Unable to read the file.';
}
