in_array wouldnt work? strstr did why?

[redarrow]

This was to match two letters together, 1 was from a post / form,another from a array.

 

it working this way but in_array wouldnt work ...

 

Please can you give an example of in_array, matching a posted letter and a array letter cheers.

 

 

 

<?php

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

$quostionb=array("a");

$quostiona=$_POST['quostiona'];


    if(strstr($quostiona,implode($quostionb," "))){
        
      echo"<p> ansaw is: ".implode($quostionb," ")." ";
    }else die();
     }
?>


<form method="POST" action=" ">

<select name="quostiona">

<option value="a">a</option>
<option value="b">b</option>
</select>

<input type="submit" name="submit" value="send">

</form>

When issues like that pop up, it's usually due to whitespace present in one of the values, and not the other.
