Run PHP on the Google App Engine

anyway for the php to access any kind of database. – I know that Memcached is provided by GAE so we can use that by simply adding a key value pair.

@Unreality
Google App Engine’s datastore has a SQL-like syntax called “GQL”. Select statements in GQL can be performed on one table only. GQL intentionally does not support the Join statement, because it is seen to be inefficient when queries span more than one machine. Instead, one-to-many and many-to-many relationships can be accomplished using ReferenceProperty().This shared-nothing approach allows disks to fail without the system failing.
The where clause of select statements can perform >, >=, <, <= operations on one column only. Therefore, only simple where clauses can be constructed. Switching from a relational database to the Datastore requires a paradigm shift for developers when modeling their data.
App Engine limits the maximum rows returned from an entity get to 1000 rows per Datastore call. Most web database applications use paging and caching, and hence do not require this much data at once, so this is a non-issue in most scenarios.[citation needed] If an application needs more than 1,000 records per operation, it can use its own client-side software or an Ajax page to perform an operation on an unlimited number of rows.
Unlike a relational database such as Oracle, Microsoft SQL Server, MySQL, or PostgreSQL, the Datastore API is not relational in the SQL sense.

I run your example. It works fine, thanks. But what about apache url rewriting. Is there any way to implement this?

Thanks!

I was wondering if this is possible… It seems it is

@Unreality, Still, you are getting PHP on App Engine! It’s better then nothing… For those developers that don’t want to learn the whole new language this will do for now…

PS. They can get another free hosting you might argue

Java-compiled PHP performance seems to faster than standard PHP (at least PHP without any accelerators). One must understand that querqus is NOT interpreting PHP but compiling PHP to Java classes that will be run at servlet speeds. Moreover, one gets the benefit of using more advanced PHP techniques that further speed up things.

Good job….

Good! Will try it later.

There was a misconfiguration in the first posted apps, you must edit appegine-web.xml in /war/WEB-INF/ so something like this:

heypasteit.com/clip/58J

I’m not good at regular expressions, so I’ve cheated a little bit. You’ll see when looking the XML.

How about mod_rewrite?

Dear All,

Can anyone tell me: how is about data layer on GAE? As far as I know Google uses persistence objects ( DataNucleus Access Platform) So how do you use the platorm in PHP code?

Please advise me

[...] Run PHP on the Google App Engine [...]

Actually i wanted to make a google app engine application in php using Quercus but how can i do in jsp that i don’t know, the example you have given is not dealing with database connection, so could you please explain how can we make GAE app in php+java with Quercus support which also deal with database (JDO).

Thanks,

Has anyone else run into the problem of number of files >1000 exceeding the quota? With PHP, you can easily have more files because you might include some libraries. I found that I can’t port an existing application to GAE because of the 1000 file limit. Any suggestion?

How to install WordPress on Google App Engine: digg.com/d1sZjZ

@Herbert Groot Jebbink, thanks man, but why isn’t this described at the very start of this post?

good job

JIQL, the JDBC Wrapper for Google DataStore, integrates with Quercus.
So you can run PHP applications with your same SQL queries.

If I have a legacy php5 application developed, how much modifications required to make it work inside google app engine.

is app engine for developing new apps or existing projects also ?

Thanks

Sorted, Thanks.

Thanks

nice job, many thanks.

I just added my new google app. thanks for the details.

Great work. Thanks for sharing.

Hey Prakash,
it seems like you got it, can you please help me install my app on GAE? anyhelp will be great, it#s an opensource rss php reader. Thanks in advance

Thanks a lot !

Nice post, I share my experience with Ubuntu Linux.
I changed: appcfg.cmd update C:\projects\phpwithjava\war
for : appcfg.sh update my_path/phpwithjava/war
Thank you very much.

It seems a lot of php functions result in 500 server error. Anyone have ideas on opening the library a bit more?

Thank you, supper cool post.
Ruby is also available through JRuby on Google App Engine
(http://code.google.com/p/appengine-jruby)

Yeah, please do tell how to use curl with Quercus/PHP Thanks!

OK, that seems to be a joke I have read all the Google info and found nothing…

I want run wordpress on GAE

it is good and works for me.

Has anyone got CURL working on GAE?

Thanks for sharing this information…

Is there a way to use a custom php.ini with this?

Cheers.

Nice post. Thanks.

Oops Sorry! It was Google IO 2009

@Tommy

To get around the 1,000 file limit, you might try writing a script to put all the classes in your apis into a few very large files.

Why would you want to go through so many hoops to run *PHP*, it’s a horrible programming language! Not to mention that you have to run it in Java (another horrible programming language)

– However, This is great for people who really want to run PHP with free hosting

This blog guided me when testing and creating a package for easy PHP application building on Google. Similar approach with newer libraries you can find from: php-apps.appspot.com/

I think PHP and Java is a good combination. Java for background logics and PHP for frontend UI generation.

When I started to use PHP on AppEngine, one of my biggest problem was the non-relational database access layer. I’ve developed a simple ORM framework, which supports GAE through the low level datastore API. If you interested, try it, the page of the project is code.google.com/p/lworm/

OMG THIS IS THE BEST THING SINCE THE INVENTION OF COMPUTERS!!!! Where can I give you a donation? You just saved my project weeks of work!!!

Nice Post. Thanks

This is fantastic… thanks a lot…

Anyway refreshing page is not a solution for java.lang.ClassNotFoundException: `org.mortbay.jetty.handler.ContextHandler’ issue.

1. Download jetty from jetty.codehaus.org
2. Extract the archive.
3. Copy 2 files jetty-6.1.26.jar / jetty-util-6.1.26.jar from jetty lib folder to your application’s lib folder (in WEB-INF).

Instead of curl, I used this code:

import java.net.URL;
define(‘URLFetchServiceFactory’, new Java(‘com.google.appengine.api.urlfetch.URLFetchServiceFactory’));
$data = URLFetchServiceFactory->getURLFetchService()->fetch(new URL([YOUR URL HERE]))->getContent();

So far so good!

Hi,
Thanks a lot for this article my php application is hosted on GAE. The only problem i have is with the CAPTCHA feature. I am using an open source solution called “Securimage” (phpcaptcha.org)
i use another php to instantiate the class and show a CAPTCHA image. It was working on my local Apache server but it’s not working on GAE it just display the following message:
Error: Server Error
The server encountered an error and could not complete your request.

If the problem persists, please report your problem and mention this error message and the query that caused it.

Can someone help?? Thank you

Thanks, i have use this for long time. My appengine-web.xml:

<!– For PHP-Support –>
<static-files>
<exclude path=”/**.php” />
<exclude path=”/**.inc” />
</static-files>
<resource-files>
<include path=”/**” />
</resource-files>

</appengine-web-app>

I think that is among the such a lot important information for me. And i’m satisfied reading your article. However wanna commentary on few common things, The website taste is great, the articles is truly excellent : D. Just right activity, cheers
