What are some common challenges when reading and parsing data from a text file in PHP?

One common challenge when reading and parsing data from a text file in PHP is handling different file formats and encodings. To solve this, you can use functions like `fopen`, `fread`, and `mb_convert_encoding` to read the file and convert its encoding if needed. 

$file = 'data.txt';
$handle = fopen($file, 'r');
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        // Convert encoding if needed
        $line = mb_convert_encoding($line, 'UTF-8', 'ISO-8859-1');
        
        // Parse the data from the line
        // Your parsing logic here
        
        echo $line;
    }
    fclose($handle);
} else {
    echo 'Error opening the file.';
}
