What could be causing the "Out of Memory" error in the PHP script that reads and outputs a .txt file?

The "Out of Memory" error in a PHP script that reads and outputs a .txt file could be caused by trying to load a large file into memory all at once. To solve this issue, you can read the file line by line instead of loading the entire file into memory at once. This way, you can process the file in smaller, more manageable chunks. 

<?php
$file = 'example.txt';
$handle = fopen($file, 'r');

if ($handle) {
    while (($line = fgets($handle)) !== false) {
        echo $line;
    }
    
    fclose($handle);
} else {
    echo "Error opening the file.";
}
?>
