What are some common mistakes to avoid when using PHP to read and parse data from a .txt file?

One common mistake to avoid when using PHP to read and parse data from a .txt file is not properly handling file paths. Make sure to use the correct file path to access the .txt file. Another mistake is not checking if the file exists before trying to read from it. Additionally, ensure that you close the file after reading from it to free up system resources. 

<?php
// Correct way to read and parse data from a .txt file
$filename = 'data.txt';

if (file_exists($filename)) {
    $file = fopen($filename, 'r');
    
    while (!feof($file)) {
        $line = fgets($file);
        // Parse the data as needed
        echo $line . "<br>";
    }
    
    fclose($file);
} else {
    echo "File does not exist.";
}
?>
