What are some common pitfalls when searching for files in a PHP script?

Common pitfalls when searching for files in a PHP script include not specifying the correct file path, not handling errors properly, and not checking if the file exists before trying to access it. To avoid these pitfalls, always double-check the file path, use error handling techniques like try-catch blocks, and use functions like file_exists() to check if the file exists before attempting to access it.

// Example code snippet to search for a file in a PHP script

$filename = 'example.txt';

if (file_exists($filename)) {
    $file_contents = file_get_contents($filename);
    echo $file_contents;
} else {
    echo "File not found.";
}
