What potential issues may arise when calculating the number of script lines using PHP?

One potential issue that may arise when calculating the number of script lines using PHP is that empty lines and comments may also be counted, leading to inaccuracies in the count. To solve this issue, you can use the PHP function `file()` to read the file line by line and exclude empty lines and comments before counting the total number of script lines. 

$file = 'your_script.php';
$lines = file($file);
$scriptLines = 0;

foreach ($lines as $line) {
    $trimmedLine = trim($line);
    if (!empty($trimmedLine) && strpos($trimmedLine, '//') !== 0) {
        $scriptLines++;
    }
}

echo "Total number of script lines: " . $scriptLines;
