PHP-переключатели, многомерный массив

Question

Хорошо, я не знаю, что я делаю. Думаю, я настроил свой многомерный массив. Проблема, с которой я сталкиваюсь, - это когда вы выбираете радиокнопку, результаты должны выходить. Я полный нуб в этом PHP вещи ....

Вот мой радиокнопки HTML:

<h2>List animals by </h2> 
<ul> 
<li>Habitat: (This selection doesn't work in the demonstration) 
<form action="" method="post"> 
<input type="radio" name="Habitat" value="Forest"> Forest 
<input type="radio" name="Habitat" value="Farm"> Farm 
<input type="radio" name="Habitat" value="Desert"> Desert 
<input type="submit" name="submit" value="List Animals"> 
</form> 
<li> 
Food: 
<form action="" method="post"> 
<input type="radio" name="Food" value="Meat" ?prefix=Meat> Meat 
<input type="radio" name="Food" value="Grass" ?prefix=Grass> Grass 
<input type="radio" name="Food" value="Mixed" ?prefix=Mixed> Mixed 
<input type="submit" name="submit" value="List Animals"> 
</form> 
</ul> 
<hr> 

А вот мой PHP ..... Я полный нуб в этом. Это мое первое «задание». У меня слишком много проблем. Некоторые указатели, которые наведут меня на правильный путь, были бы замечательными.

<?php 

if (isset($_post['submit'])){ 
if (isset($_post['radio'])) 



$animalList = array(); 
    $animalList[0] = array(); 
     $animalList[0] ['Animal'] = "Bear"; 
     $animalList[0] ['Habitat'] = "Forest"; 
     $animalList[0] ['Food'] = "Meat"; 
    $animalList[1] = array(); 
     $animalList[1] ['Animal'] = "Deer"; 
     $animalList[1] ['Habitat'] = "Forest"; 
     $animalList[1] ['Food'] = "Grass"; 
    $animalList[2] = array(); 
     $animalList[2] ['Animal'] = "Pig"; 
     $animalList[2] ['Habitat'] = "Farm"; 
     $animalList[2] ['Food'] = "Mixed"; 
    $animalList[3] = array(); 
     $animalList[3] ['Animal'] = "Cow"; 
     $animalList[3] ['Habitat'] = "Farm"; 
     $animalList[3] ['Food'] = "Grass"; 
    $animalList[4] = array(); 
     $animalList[4] ['Animal'] = "Sheep"; 
     $animalList[4] ['Habitat'] = "Farm"; 
     $animalList[4] ['Food'] = "Grass"; 
    $animalList[5] = array(); 
     $animalList[5] ['Animal'] = "Camal"; 
     $animalList[5] ['Habitat'] = "Desert"; 
     $animalList[5] ['Food'] = "Grass"; 
    $animalList[6] = array(); 
     $animalList[6] ['Animal'] = "Scorpion"; 
     $animalList[6] ['Habitat'] = "Desert"; 
     $animalList[6] ['Food'] = "Meat"; 



function showAnimals($prefix_requested){ 

    global $animalList; 

    $tbl = "<table border=1>"; 
    $tbl = $tbl."<tr><th>Animal</th><th>Habitat</th><th>Food</th></tr>"; 

    foreach ($animalList as $animal){ 

     if ($animal['Animal'] == $prefix_requested){ 

    $tbl .= "<tr><td>{$animal['Animal']} 
      {$animal['Habitat']}</td><td>   
      {$animal['Food']}</td></tr>"; 
     } 
    } 

    $tbl .="</table>"; 
    echo $tbl; 
    } 


    echo "".$_post['radio']; 
} 


?> 

Немного длинный, я знаю ... если бы кто-то мог меня правильно направить, я был бы так благодарен !!!!!
