comparing array value to textbox input

Couldn't find any solution on this yet, so I'm posting it here.

I have the following code: 

<?php
//array: key=> value
$begrippen = array(
    "agrarisch" => "jagers en boeren",
    "cultuur" => "jagers en boeren",
    "jagers-verzamelaars" => "jagers en boeren",
    "landbouwsamenleving" => "jagers en boeren",
    "burgerschap" => "grieken en romeinen",
    "christendom" => "grieken en romeinen",
);
$message1 = 'Goedzo!';
$message2 = 'Fout!';

$random_key = array_rand($begrippen);
$value = $begrippen[$random_key];
echo "Begrip: $random_key <br />";
?>

<form method="POST">
<input type="text" autocomplete="off" name="input1" autofocus>
</form>

<?php
if($_POST['input1'] == $value){
    echo "<SCRIPT> alert('$message1'); </SCRIPT>";
}else{
    echo "<SCRIPT> alert('$message2'); </SCRIPT>";
};
?>

It takes a random key from my array, takes the value and puts that in $value. When I enter input in my textbox, I want it to compare with $value and let it show a message (good or wrong). Yet something goes wrong and I don't know what because sometimes it says it's good, and sometimes it's wrong (while the answer was correct).

Try this,

You can add hidden field in your form and assign the value to be refer. 

<form method="POST">
    <input type="text" autocomplete="off" name="input1" autofocus>
    <input type="hidden" name="inputref" value="<?php echo $value;?>">
    <input type="submit" name="submit" value="Submit">
</form>

in PHP: your condition will be 

if(isset($_POST['submit'])){

   if($_POST['input1'] == $_POST['inputref']){
   ... Your code
   }
}

I don't know without form submitting how this will work? So add a button as submit inside your form.

You need to do change your logic When POST request called.

<?php
if($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['check'])){
    //array: key=> value
    $begrippen = array(
       "agrarisch" => "jagers en boeren",
       "cultuur" => "jagers en boeren",
       "jagers-verzamelaars" => "jagers en boeren",
       "landbouwsamenleving" => "jagers en boeren",
       "burgerschap" => "grieken en romeinen",
       "christendom" => "grieken en romeinen",
   );
   $message1 = 'Goedzo!';
   $message2 = 'Fout!';

   $random_key = array_rand($begrippen);
   $value = $begrippen[$random_key];
   echo "Begrip: $random_key <br />";
   if($_POST['input1'] == $value){
      echo "<SCRIPT> alert('$message1'); </SCRIPT>";
   }else{
      echo "<SCRIPT> alert('$message2'); </SCRIPT>";
   }
}
?>
<form method="POST">
   <input type="text" autocomplete="off" name="input1" autofocus />
   <input type="submit" value="Check" name="check" />
</form>
