What are the potential pitfalls of using implode and explode functions in PHP when reading data from a text file?

One potential pitfall of using implode and explode functions in PHP when reading data from a text file is that they may not handle large amounts of data efficiently, leading to memory consumption issues. To solve this problem, it is recommended to read the file line by line and process each line individually. 

$file = fopen('data.txt', 'r');
if ($file) {
    while (($line = fgets($file)) !== false) {
        $data = explode(',', $line);
        // Process data here
    }
    fclose($file);
} else {
    echo "Error opening file.";
}
