If/else with an area for echo's - php

Question

So Im having a bit of a conundrum. Not too sure how I should go about doing the if/else statements with an Echo at the top with the answers, with bullets.
<?php
echo
?>
</p>
<p>
A Chicken
<input type="radio" name="radio" id="radio3" value="no">
<label for="radio3">Choose this answer</label>
</p>
<p dir="ltr">A Ear of Corn.
<input type="radio" name="radio" id="radio2" value="no">
<label for="radio2">Choose this answer</label>
</p>
<p dir="ltr"> A Heart.
<input type="radio" name="radio" id="radio" value="yes"> Choose this answer
</p>
<p dir="ltr">
<input type="button" name="button28" id="button28" value="Yes! That is the answer I chose!">

Answer 1

If your question is basically about how to output certain HTML code based on an if/else clause, then with such a lengthy amount of HTML code as you have posted you would do much better using HEREDOCS checkout the PHP manual here: http://php.net/manual/en/language.types.string.php.
Goodluck!

Answer 2

You can do this on many ways. Here is a small example to get you started working with forms.
<?php
$answer = '';
if(isset($_POST['send']) //check if the form has been sent
&& isset($_POST['answer'])){ //check if an answer is filled in
//You could also use a switch -> http://php.net/manual/en/control-structures.switch.php
if($_POST['answer'] == 'chicken'){ //check if post variable answer value = chicken
$answer = 'your answer is "a chicken"';
}elseif($_POST['answer'] == 'corn'){ //check if post variable answer value= corn
$answer = 'your answer is "A Ear of Corn."';
}elseif($_POST['answer'] == 'heart'){ //check if post variable answer value = heart
$answer = 'your answer is "A Heart"';
}
//echo the variable.
echo $answer;
}
?>
<form method="POST" action="">
<p> A Chicken
<input type="radio" name="answer" id="radio3" value="chicken">
<label for="radio3">Choose this answer</label>
</p>
<p dir="ltr">A Ear of Corn.
<input type="radio" name="answer" id="radio2" value="corn">
<label for="radio2">Choose this answer</label>
</p>
<p dir="ltr">A Heart.
<input type="radio" name="answer" id="radio" value="heart">Choose this answer
</p>
<input type="submit" name="send" id="button28" value="Yes! That is the answer I chose!">
</form>
