If you are trying to find if the value is in the array and echo it, then I would suggest trying this.

<?php
if(isset($_POST["submit"]))
{
  $text = $_POST['text'];
  $book= array("PHP"=>"PHP Hypertext Preprocessor",
  "ASP"=> "Active Server Page",
  "JSP"=>"Java Server Page",
  "CSS"=>"Cascading Style Sheets");

  $st = false;

  foreach ($book as $index => $value)
  {
    if ($text == $index || $value)
    {
      echo "Result - " . $index . " : " .$value . "<br />";
      $st = true;
    }
  }


  if($st == false)
  {
    echo "No result found<br />";
  }

}
?>

Also ("PHP" => "PHP Hypertext Processor")


If this is not what you were after, please elaborate on what you are querying and I would be more than happy to assist you. But from what you have given, this is what I assumed and have given information for.

sounds a lot of unncesary code to me. this will easily do the same.

<?php

if(isset($_POST["submit"]))

{

  $book= array("PHP"=>"PHP Hypertext Preprocessor",

  "ASP"=> "Active Server Page",

  "JSP"=>"Java Server Page",

  "CSS"=>"Cascading Style Sheets");


    if (array_key_exists($_POST['text'], $book) {

        echo "Result - " . $_POST['text'] . " : " .$book[$_POST['text']] . "<br />";

    } else {

        echo "No result found<br />";

    }

}

Thank you !

[Drew]

Well, yes, there was unneccisary code, because ti seemed like it would be used elsewhere as well.

Thanks for tidying it up, looks better to me as well.

Also, mine looks longer because it has more logical formatting, well, as I was taught to do. Not saying yours is wrong or nothing, just saying about the way I was taught to format my code so it's easy to follow.

Mainly bracket wise.

[Orjan]

about on how to write brackets, it's many different schools on how to do it. best if you choose one and stick to that one, but learn some of the others ways too, so you can make changes in others code and write as they done in that program so your change look different. It wasn't supposed to change that... I just wanted to show that it was possible to do the same in a simple manner, that actually can be easier to follow, and with less variables used to follow, but you are right, in a larger context, it might not be the ideal solution, as every design decision depends on the context.

[Drew]

I agree completely with you there wise Orjan.
You did what you did, and it's another way to do it. And there are many ways. "To each their own."
You put that a very good way.
