What is the significance of the "eval" function in the PHP code snippet?

The "eval" function in PHP allows for the execution of a string as PHP code. However, using "eval" can introduce security vulnerabilities as it can execute arbitrary code. It is generally not recommended to use "eval" unless absolutely necessary, as there are usually safer alternatives available. 

// Original code snippet using eval
$code = 'echo "Hello, World!";';
eval($code);
```

```php
// Code snippet without using eval
$code = 'echo "Hello, World!";';
echo $code;
