How to optimize if else in post method?-CodePudding

I have mainly two question first describe what I going to do. I've created some animal in the code by saying that octopus will have 8 leggs,9 brain,1 stomach,3 heart similarly for other property.And by a html form using post method I'm taking input from user as showing the animals image if the description matches.

I've also declared the corresponding animals name.I want to also show the name of the animal after matching(by printing $name). 2)Here I'm matching user input for each animal(by using if,elseif elseif) but how can I optimize so that if there is more than 100 animal I don't have to do 100 else if. Here is my code.

<?php
   class animal{
       var $name;
       var $brain;
       var $stomach;
       public $heart;
       public $leg;

       function __construct($aBrain, $aStomach, $aHeart, $aLeg)
       {
           $this->brain = $aBrain;
           $this->stomach = $aStomach;
           $this->heart = $aHeart;
           $this->setLeg($aLeg);
       }
       
       function isBipedal(){
           if ($this->leg == 2) {
               return "it is a bipedal animal";
           }else {
            return "it is not a bipedal animal";
           }
       }

       function getLeg(){
           return $this->leg;
       }

       function setLeg($leg){
           if ($leg == 8 ||$leg == 4 ||$leg == 2) {
            $this->leg= $leg; 
           }else {
            $this->leg= "non-pedal"; 
           }
       }
    }
    $octopus = new animal(9,1,3,8);  
    $cow = new animal(1,4,1,4); 
    $human = new animal(1,1,1,2);

    $octopus->setLeg(8);
    //echo  "new leg ".$octopus->leg = 0; 

    echo "<br>".$octopus->getleg();

    echo "<br>".$human->isBipedal(). "<br>"; 
    

    if(isset($_POST['submit']))  { 
        if(isset($_POST['brain']) 
        && isset($_POST['stomach'])  
        && isset($_POST['heart']) 
        && isset($_POST['leg']) ){

            $myBrain = $_POST['brain'];
            $myStomach = $_POST['stomach'];
            $myHeart = $_POST['heart'];
            $myLeg = $_POST['leg'];
            
            // echo "brain = ". $myBrain. "<br>"; 
            // echo "stomach = ". $myStomach. "<br>";
            // echo "heart = ". $myHeart. "<br>";
            // echo "leg = ". $myLeg. "<br>";

            if($myBrain==$octopus->brain
            && $myStomach==$octopus->stomach
            && $myHeart==$octopus->heart

u should either store them in a DB and make a query, or store them in array and search by some linq equivalent in php

Could You try with a Switch case?

<?php
if ($i == 0) {
    echo "i equals 0";
} elseif ($i == 1) {
    echo "i equals 1";
} elseif ($i == 2) {
    echo "i equals 2";
}

switch ($i) {
    case 0:
        echo "i equals 0";
        break;
    case 1:
        echo "i equals 1";
        break;
    case 2:
        echo "i equals 2";
        break;
}
?>
