Are there any potential pitfalls in using fpassthru() to output file content in PHP scripts?

One potential pitfall of using fpassthru() to output file content in PHP scripts is that it may not handle large files efficiently, as it reads the entire file into memory before outputting it. To avoid this issue, you can use a loop to read and output the file content in smaller chunks. 

$file = fopen('example.txt', 'r');

while (!feof($file)) {
    echo fread($file, 8192);
}

fclose($file);
