PHP 4.x Easter Egg - Author's Picture

For those who have no idea what PHP is, you can see the image here: http://www.zend.com/zend/products.php?=PHPE9568F36-D428-11d2-A769-00AA001ACF42 It is totally funny!!!

This works with PHP4 for Windows as well. You would think someone would find this whole routine in the source.

I'm no C wizard, but I believe this image is shown in stead of the php logo on top of the phpinfo() page on march 1st. Look in ext/standard/info.c line 166

Interested in seeing the source of this egg? It's contained within three files, have a look here : http://lxr.php.net/ident?i=PHP_EGG_LOGO_GUID Was added on around April 2000.

This picture appears on April 1st when a file containing the following directive is run:

If the PHP directive expose_php is off (in php.ini), this "egg" will not show.

There are a total of 3 different pictures hidden in PHP V4+ You can use this on any site that has PHP. http://www.flight1721.co.uk/index.php?=PHPE9568F34-D428-11d2-A769-00AA001ACF42 http://www.flight1721.co.uk/index.php?=PHPE9568F35-D428-11d2-A769-00AA001ACF42 http://www.flight1721.co.uk/index.php?=PHPE9568F36-D428-11d2-A769-00AA001ACF42 In fact if you see a URL ending in .php add ?=PHPE9568F34-D428-11d2-A769-00AA001ACF42 or ?=PHPE9568F35-D428-11d2-A769-00AA001ACF42 or ?=PHPE9568F35-D428-11d2-A769-00AA001ACF42 to the end of the URL and see for yourself. Works on all platforms as they have the same actual source code!

Also ... http://www.flight1721.co.uk/index.php?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000 shows the list of credits for PHP.

The only truly hidden image is the "?=PHPE9568F36-D428-11d2-A769-00AA001ACF42" one - the rest are called from the page produced by the phpinfo() function, which actually works on any day of the year.

the id for the image changes every version - but to make it easier, you could write yourself a tiny php module containing a funktion like this: function_entry easter_functions[] = { PHP_FE(easter_egg, NULL) {NULL, NULL, NULL} /* Must be the last line in easter_ffunctions[] */ }; PHP_FUNCTION(easter_egg) { // zend_alter_ini_entry("expose_php", sizeof("expose_php"), "On", 2, PHP_INI_SYSTEM, PHP_INI_STAGE_ACTIVATE); php_info_logos(PHP_EGG_LOGO_GUID); } (the rest can be used instantly from ext_skel) or just put it in your usual dev-helper module.

Make a file, in the file contain this: Run this file in webserver Look at first line PHP Version x.y.z ................ PHP Logo That image point to ?=PHPE9568F34-D428-11d2-A769-00AA001ACF42 Look at the first grey box This program makes use of the Zend Scripting Language Engine: Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies ............... Powered by Zend logo That image point to ?=PHPE9568F35-D428-11d2-A769-00AA001ACF42 Under that link, have a link saying PHP Credit, That link point to ?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000 That's why these are here, some of them shall not egg. They're here just to work with phpinfo(); Take a look at php-source/ext/standard/info.h #define PHP_LOGO_GUID "PHPE9568F34-D428-11d2-A769-00AA001ACF42" #define PHP_EGG_LOGO_GUID "PHPE9568F36-D428-11d2-A769-00AA001ACF42" #define ZEND_LOGO_GUID "PHPE9568F35-D428-11d2-A769-00AA001ACF42" #define PHP_CREDITS_GUID "PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000"

Nice egg!!! This is awesome, but the URLS posted are outdated. This is probably because there are new and better php versions, so the sites probably moved. There still are some sites which run on 4.0 though. To view the funny image go here: http://www.phpfreaks.com/error.php?=PHPE9568F36-D428-11d2-A769-00AA001ACF42 To view the logos, go here: http://www.phpfreaks.com/error.php?=PHPE9568F34-D428-11d2-A769-00AA001ACF42 http://www.phpfreaks.com/error.php?=PHPE9568F35-D428-11d2-A769-00AA001ACF42 And finally, to view the credits (boring and not quite an eegg - its in the documentation) go here: http://www.phpfreaks.com/error.php?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000 Of course, you can view the egg on any php website you like, you just have to add the ?=PHPB8... part to it. Have fun searching for other cool eggs!
