What are some best practices for implementing a text ticker in PHP that reads from an external file?

To implement a text ticker in PHP that reads from an external file, you can start by creating a PHP script that reads the content of the external file line by line and displays it in a scrolling manner. You can use PHP's file handling functions to read the content of the file and then output it in a loop to create the scrolling effect. 

<?php
// Open the external file for reading
$file = fopen('external_file.txt', 'r');

// Read the content of the file line by line
while (!feof($file)) {
    $line = fgets($file);
    
    // Output the line with scrolling effect
    echo '<marquee>' . $line . '</marquee>';
    
    // Adjust the speed of the scrolling effect by adding a delay
    usleep(500000); // 0.5 seconds delay
}

// Close the file
fclose($file);
?>
