What potential issues can arise when using fgets() to read a file in PHP?

One potential issue when using fgets() to read a file in PHP is that it reads the file line by line, which can be inefficient for large files. To solve this, you can use fread() to read the file in larger chunks instead of line by line. 

$handle = fopen("file.txt", "r");
if ($handle) {
    while (!feof($handle)) {
        $chunk = fread($handle, 8192); // Read 8KB at a time
        // Process the chunk
    }
    fclose($handle);
}
