PHP si MySQL Ok. Stii Photoshop, HTML si CSS. Faci template-uri. N-ai vrea sa-ti usurezi munca, sa poti crea site-uri dinamince folosind programarea in PHP si baze de date MySQL?

Default [Lectia-1]Introducere
Introducere:

Ce este PHP ?
PHP ("PHP: Hypertext Preprocessor") este un limbaj de scripting (server side) de uz general, cu cod-sursa deschis (open-source). Este folosit in special pentru dezvoltarea aplicatiilor web ( situri in special siturile dinamice ce folosesc baze de date [mysql, postgresql ..]) si poate fi integrat in HTML.

Inceputul scriptului in php se face prin deschiderea tagului <?php sau <? sau <script language="php"> iar inchiderea prin ?> sau in cazul script prin </script>

Codul php nu este vizibil in browser doar output-ul, deoarece se executa pe server.

Ca sa rulati php pe pc-ul personal va recomand pachetul apache2triad (http://www.apache2triad.net) sau xampp(http://www.apachefriends.org/en/xampp.html) deoarece el contine apache, php, mysql si alte programe dar pe noi ne intereseaza doar apache/php/mysql (amp).

Exemplu: (test.php)

Code:
<html>
<head>
	<title>Titlu</title>
</head>
<body>
<?php
	echo 'Hello world';
?>
</body>
</html>

echo - afiseaza textul dintre ' '
<?php - deschide scriptul php
?> - inchide scriptul php

Nici la lectia asta tema. De asemenea, daca aveti intrebari sau nelamuriri in legatura cu Lectia 1 dati un reply.

Acel ; termina linia respectiva. Daca ai sa zicem

echo 'Test';
echo 'Test2'; si nu pui ; o sa dea eroare pentru ca nu inchide linia.
