Build Status

This is a PHP extension for the appserver.io project.

The extension replaces some PHP system functions like get_headers() with appserver_get_headers() because they lead to serious problems when running a daemon like appserver.io that provides functionality like a web server.

###Ini Settings

The extension also allows you to remove functions and constants before the runtime has started up. So it's possible to write you own core functions (strlen, headers_sent) or modify some consts set by a sapi (PHP_SAPI) all in php userland.

#####appserver.php_sapi This setting reset's the default PHP_SAPI to given value

appserver.php_sapi = appserver

#####appserver.phpinfo_as_text This setting defines the output format for phpinfo() to be either text or html.

appserver.phpinfo_as_text = 1

#####appserver.remove_functions This setting hold's a comma separated list of all function to remove on runtime startup. If you want to define your own custom core php function for strlen and headers_sent in userland just use:

appserver.remove_functions = strlen,headers_sent

#####appserver.remove_constants This setting hold's a comma separated list of all constants to remove on runtime startup. If you want to define your own custom core constant for PHP_SAPI and PHP_VERSION in userland just use:

appserver.remove_constants = PHP_SAPI,PHP_VERSION

###Functions

#####appserver_get_headers(boolean $reset = false) This function will return an array of headers set by php core header function and will reset the global headers hash table after returning it if $reset param is true. $reset param is optional.

#####appserver_register_file_upload(string $filepath) Registeres an uploaded file top super global hash table rfc1867_uploaded_files at runtime like sapi apache would do it when a file upload occurs, so the function move_uploaded_file can still be used as usual.

#####appserver_set_headers_sent(boolean $sent) If you want to reset the flag that headers already sent while runtime you can easly do it with this function by calling appserver_set_headers_sent(false);

#####appserver_set_raw_post_data(string $postData) To have the raw post data available in php://input you can simple use this function. I'll be available in $HTTP_RAW_POST_DATA too.

#####appserver_get_http_response_code() Gets the http response code if is set in sapi_headers hash table.

#####appserver_session_init() Resets the whole session environment while in process runtime. It's needed when you what to use internal session_start() functionality in a multithreaded daemon process.

#####appserver_stream_import_file_descriptor(resource $streamResource) It will return the file descriptor as userland int of a php stream resource. So you have the possibility to reopen any open stream socket fd with fopen('php://fd/XX'); in any context.

Debug on Mac OS X

Additionally it provides various functionality for usage within the appserver.io runtime.

We're working with the Eclipse IDE for C/C++, which you can download from. As we provide some ANT targets that helps you to prepare your PHP, you additionally have to activate the ANT View, optionally you can also use ANT from the command line, if available.

As appserver.io on Mac OS X is delivered with some precompiled libraries, it is also necessary that you have the latest version of appserver.io installed in the default directory /opt/appserver before start to prepare PHP for debugging mode.

To debug the application server you have to do the following steps:

Prequesites

Open the /etc/launchd.conf and add the following lines if not already available:

limit maxfiles 100000 100000
setenv PATH /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
setenv LANG de_DE.UTF-8

Step 1 - Clone sources:

$ git clone https://github.com/techdivision/php-ext-appserver.git

Step 2 - Build PHP with --enable-debug

Compile PHP configured with --enabled-debug and all other configuration switches appserver.io has been compiled with.

$ ant init-build

Step 3 - Start the debugger

To make debugging easy for you, we've added launch configuration files to the Eclipse project. You can find them in the root folder of the extension, they are named:

  • appserver.launch
  • php-ext-appserver.launch

As soon as you have added the project's GIT repository to Eclipse and created a new C/C++ project you should find the debug configurations available in the debug configurations menu.

To start debugging you simply have to select appserver from the debug menu and appserver.io should start in debug mode.
