We need style! CSS
Cascading Style Sheets1996
Separation of content from presentation!
We need power! Presenting static data is
limited, we want interactivity and dynamic
data
Client Side JavaScript
1996
Server Side PHPLAMP1995
<?php$con = mysql_connect("localhost","peter","abc123");if (!$con) { die('Could not connect: ' . mysql_error()); }
mysql_select_db("my_db", $con);
$result = mysql_query("SELECT * FROM Persons");
echo "<table border='1'><tr><th>Firstname</th><th>Lastname</th></tr>";
while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['FirstName'] . "</td>"; echo "<td>" . $row['LastName'] . "</td>"; echo "</tr>"; }echo "</table>";
mysql_close($con);?>
Other web frameworks Java
C# .NETPerl
PythonRuby
