What is the difference between using regular expressions and tabulators for text file parsing in PHP?

Regular expressions are more powerful and flexible for matching patterns in text, but can be more complex to write and understand. Tabulators, on the other hand, are simpler and easier to use for parsing text files that have a consistent tabular format. The choice between regular expressions and tabulators depends on the specific requirements of the text file being parsed. 

// Using regular expressions for text file parsing
$pattern = '/(\d+)\s+(\w+)\s+(\d+)/';
$file = file_get_contents('data.txt');
preg_match_all($pattern, $file, $matches, PREG_SET_ORDER);
foreach ($matches as $match) {
    echo "ID: " . $match[1] . ", Name: " . $match[2] . ", Age: " . $match[3] . "\n";
}
```

```php
// Using tabulators for text file parsing
$file = fopen('data.txt', 'r');
while (($line = fgets($file)) !== false) {
    $data = explode("\t", $line);
    echo "ID: " . $data[0] . ", Name: " . $data[1] . ", Age: " . $data[2] . "\n";
}
fclose($file);
