Welche Herausforderungen können auftreten, wenn Dateieinträge mit mehreren Zeilen verarbeitet werden sollen?

When processing file entries with multiple lines, a challenge that can arise is ensuring that each line is correctly read and processed. One solution is to use a loop to read each line of the file and process it individually. 

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

if ($file) {
    while (($line = fgets($file)) !== false) {
        // Process each line here
        echo $line;
    }
    fclose($file);
} else {
    echo "Error opening file.";
}
