Why does using $_POST within a string cause an issue in PHP?

Using $_POST within a string in PHP can cause an issue because the value of $_POST is an array, not a string. To fix this issue, you need to access the specific value of $_POST using the appropriate key before concatenating it within a string. 

// Example of fixing the issue by accessing the specific value of $_POST before using it in a string
$name = $_POST['name'];
echo "Hello, $name!";
