In the provided PHP code snippet, what issue arises from overwriting the $tags variable in the foreach loop?

Overwriting the $tags variable in the foreach loop will result in losing access to the original array of tags. This can lead to unexpected behavior and errors in the code. To solve this issue, you can use a different variable name within the foreach loop to avoid overwriting the original $tags array. 

// Original code snippet
$tags = ['PHP', 'JavaScript', 'HTML', 'CSS'];

foreach ($tags as $tag) {
    // Overwriting $tags variable
    $tags = 'Overwritten';
    echo $tag . "\n";
}
```

```php
// Fixed code snippet
$tags = ['PHP', 'JavaScript', 'HTML', 'CSS'];

foreach ($tags as $tag) {
    // Using a different variable name to avoid overwriting $tags array
    $currentTag = $tag;
    echo $currentTag . "\n";
}
