2. What's Quercus
 Quercus 100% Java implementation of PHP
 PHP run on JVM (not Zend Engine)
 Opensource GPL license

3. Why?
● Performance
– Up to 4x faster on some applications
● Security
– Avoids buffer overflow problems in C-based
implementation
● Java/PHP integration
– PHP can now access any Java library or objects
– Java can use PHP as a view technology

4. Why? (continue)
● PHP on Google App Engine
– Google cloud computing
● Long Live Process (worker)
– Php process ~ 82 live hours
- Java process ∞ live hours
● Delicate Cache vs Cache on process

5. Existing PHP applications on
Quercus
 Mediawiki  Gallery2
 Wordpress  Php-Nuke
 DokuWiki  PhpMyAdmin
 Drupal  Openads

6. PHP+JAVA

7. Working with Java classes in PHP
<?php
$a = new Java("java.util.Date", 123);
echo $a->time;
?>
OR
<?php
import java.util.Date;
$a = new Date(123);
echo $a->time;
?>

8. PHP Module
 Standard modules
Quercus implements the standard PHP libraries
(arrays, strings, date, regexp, zip ,zlib mcrypt, bcmath.

9. PHP Ext Module
 APC (object caching)
 Image support ('gd')
 PDF generation (PDFlib api)
 AJAX (JSON)
 GetText (localization)

10. Using Databases (PHP API)
 MySQL
 PostgreSQL
 Oracle

11. Java Module
All, of course !!!

12. Benefits of Quercus
 Performance - simply faster
 Development - fast, safe, and easy
 Capability - powerful Java technologies
 Security - no more pesky C memory bugs
 Scalability - Massive clusters of PHP
 Internationalization - 16-bit unicode

13. Demo
<?php
$a=time();
$arr = array();
for($i=0;$i<10000000;$i++)
{
$arr[i] = $i;
}
sort($arr);
$b=time();
echo $b-$a;
?>
