What are some potential pitfalls when using PHP to output text from a text file in a news ticker format?

One potential pitfall when using PHP to output text from a text file in a news ticker format is not properly handling the file reading and formatting. To solve this, you should ensure that the file is read line by line and each line is formatted appropriately for the news ticker display. 

<?php
// Open the text file for reading
$filename = 'news.txt';
$handle = fopen($filename, 'r');

// Check if the file opened successfully
if ($handle) {
    // Display each line of the text file as news ticker
    while (($line = fgets($handle)) !== false) {
        echo '<marquee>' . $line . '</marquee>';
    }
    
    // Close the file handle
    fclose($handle);
} else {
    echo 'Error opening the file.';
}
?>
