PHP radio button group variables - php

Question

I've simplified it for this question. But all I need to do is show a different result if a combination of buttons is checked. At the moment if Rice and Tea are checked there are no results.
<?PHP
if (isset($_POST['Submit1'])) {
$selected_radio = $_POST['food']."|".$_POST['drink'];
if ($selected_radio == 'rice' && 'tea') {
print '<h1>Rice and tea</h1>';
}
else if ($selected_radio == 'beans' && 'coffee') {
print '<h1>Beans and coffee</h1>';
}
}
?>
<form name ="form1" method ="POST" action =" ">
<p><input type = 'Radio' Name ='food' value= 'rice'>Rice</p>
<p><input type = 'Radio' Name ='food' value= 'beans'>Beans</p>
<p><input type = 'Radio' Name ='drink' value= 'tea'>Tea</p>
<p><input type = 'Radio' Name ='drink' value= 'coffee'>Coffee</p>
<input type = "Submit" Name = "Submit1" value = "Select">
</form>
(Apologies for asking a similar question earlier)

Answer 1

Update if condition
if (isset($_POST['Submit1'])) {
$selected_radio = $_POST['food']."|".$_POST['drink'];
if ($selected_radio == 'rice|tea') {
print '<h1>Rice and tea</h1>';
}
else if ($selected_radio == 'beans|coffee') {
print '<h1>Beans and coffee</h1>';
}
}

Answer 2

Change the condition of your if:
if (strpos($selected_radio, 'rice') !== FALSE && strpos($selected_radio, 'tea') !== FALSE) {
print '<h1>Rice and tea</h1>';
}
else if (strpos($selected_radio, 'beans') !== FALSE && strpos($selected_radio, 'coffee') !== FALSE) {
print '<h1>Beans and coffee</h1>';
}
(It's just a suggestion and I don't tested it ;))

Answer 3

Use this code:
$selected_radio_list = [
'rice|tea' => 'foo',
'beans|coffee' =>'bar'
];
$post = $_POST['food']. "|" .$_POST['drink'];
if(in_array($post, $selected_radio_list )){
echo $selected_radio_list[$post];
}
