PHP_______________________________________________________________________________________________________________

PHP is an open source server-side scripting language designed for Web development to produce dynamic Web pages.
It is one of the first developed server-side scripting languages to be embedded into an HTML source document rather
than calling an external file to process data. The code is interpreted by a Web server with a PHP processor module
which generates the resulting Web page. It also has evolved to include a command-line interface capability and can
be used in standalone graphical applications. PHP can be deployed on most Web servers and also as a standalone
shell on almost every operating system and platform, free of charge. PHP was a competitor to Microsoft's Active
Server Pages (ASP) server-side script engine and similar languages, but gradually received better acceptance than
ASP and by now PHP is installed on more than 20 million Web sites and 1 million Web servers. Notable software that
uses PHP includes Drupal, Joomla, MediaWiki, and WordPress.

PHP was originally created by Rasmus Lerdorf in 1995. The main implementation of PHP is now produced by The PHP
Group and serves as the formal reference to the PHP language. PHP is free software released under the PHP License,
which is incompatible with the GNU General Public License (GPL) due to restrictions on the usage of the term PHP.

While PHP originally stood for Personal Home Page, it is now said to stand for PHP: Hypertext Preprocessor,
a recursive acronym.

<?php
     // try-catch blok u kome se otvara konekcija na bazu i vrsi upit
     try {
         $konekcioni_string = "sqlite:c:/wamp/Sqlite/preduzece.db";
         // $dbh objekat pamti konekciju prema bazi
         $dbh = new PDO($konekcioni_string);
         // konstrukcija SQL izraza
         $sql = "SELECT * FROM radnik";
         // $dbh->query() vraca PDOStatement objekat
         $pdo_izraz = $dbh->query($sql);
         // Svi podaci se vracaju u obliku niza asocijativnih nizova
         $niz = $pdo_izraz->fetchALL(PDO::FETCH_ASSOC);
         // Iterisanje po vracenim rezultatima
         echo "<table cellpadding='5' border='1'>";
         echo "<tr><th>Ime</th><th>Adresa</th><th>Plata</th></tr>";
         foreach($niz as $radnik) {
             echo "<tr><td><b>".$radnik['ime']."</b></td>";

             echo "<td>".$radnik['plata']."</td></tr>";
         }
         echo "</table>";
        }
        catch(PDOException $e) {
          echo "GRESKA: ";
          echo $e->getMessage();
     }
     $dbh = null;
