Integrating eAccelerator Into PHP5 And Lighttpd (OpenSUSE 11.2)
This guide explains how to integrate eAccelerator
into PHP5 and lighttpd on an OpenSUSE 11.2 system. From the eAccelerator
project page: "eAccelerator is a free open-source PHP accelerator,
optimizer, and dynamic content cache. It increases the performance of
PHP scripts by caching them in their compiled state, so that the
overhead of compiling is almost completely eliminated. It also optimizes
scripts to speed up their execution. eAccelerator typically reduces
server load and increases the speed of your PHP code by 1-10 times."

// The following example will demonstrate how a web page can fetch information from a database with AJAX:
Example Explained - The HTML Page
When a user selects a user in the dropdown list above, a function called "showUser()" is executed. The function is triggered by the "onchange" event:
Person info will be listed here.
The showUser() function does the following:
* Check if a person is selected
* Create an XMLHttpRequest object
* Create the function to be executed when the server response is ready
* Send the request off to a file on the server
* Notice that a parameter (q) is added to the URL (with the content of the dropdown list)
The PHP File
The page on the server called by the JavaScript above is a PHP file called "getuser.php".
The source code in "getuser.php" runs a query against a MySQL database, and returns the result in an HTML table:
$q=$_GET["q"];
$con = mysql_connect('localhost', 'peter', 'abc123');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("ajax_demo", $con);
$sql="SELECT * FROM user WHERE id = '".$q."'";
$result = mysql_query($sql);
echo "
Firstname
Lastname
Age
Hometown
Job
";
while($row = mysql_fetch_array($result))
{
echo "
";
echo "
" . $row['FirstName'] . "
";
echo "
" . $row['LastName'] . "
";
echo "
" . $row['Age'] . "
";
echo "
" . $row['Hometown'] . "
";
echo "
" . $row['Job'] . "
";
echo "
";
}
echo "
";
mysql_close($con);
?>
Explanation: When the query is sent from the JavaScript to the PHP file, the following happens:
1. PHP opens a connection to a MySQL server
2. The correct person is found
3. An HTML table is created, filled with data, and sent back to the "txtHint" placeholder
