Re: [Proposal] Stream_Var

Hi Stephan, I'm having a bit of difficulty imagining a reason I would use this instead of just accessing an array, can you provide a practical example, maybe the one that inspired you to write this, if there was anything? Greg Stephan Schmidt wrote:

Hi PEAR-Devs, I'd like to propose a new package called Stream_Var. This package allows stream based access to variables using the stream wrappers that have been introduced in PHP4.3.2 That means you can do things like: $fp = fopen('var://GLOBALS/anyGlobalVar', 'r'); and then use fread, fwrite, fseek, etc. on this filepointer to read from and modify the variable. It supports GLOBALS, GET, POST, etc. If 'anyGlobalVar' is an array, it behaves like a directory, that means you could do the following: $fp = fopen('var://GLOBALS/anyGlobalVar/anyKey', 'r'); of course with an unlimited depth :-) As arrays are directories, also the following is possible: $dir = opendir('var://GET'); while($entry = readdir($dir)) { echo "$entry<br />"; } I still need to implement some minor things like different file modes (r,r+,w,w+,a,...) and options so it's possible to trigger errors, that give more detail, but the basic functionality is included. @Greg: Yes, I know that I still have to include some inline documentation, on which problem it does solve :-) I'll do that before the first version is released. You can take a look at the sourcecode at: http://www.php-tools.de/PEAR/Stream_Var/Var.phps Download it, with examples from: http://www.php-tools.de/PEAR/Stream_Var/Stream_var.zip You can also take a look at the sourcecode of the examples at: http://www.php-tools.de/PEAR/Stream_Var/examples/example.phps http://www.php-tools.de/PEAR/Stream_Var/examples/example2.phps The will not work on this server, as PHP4.3.2 is not installed :-( (I already informed the hoster), but you can download the zip and test it on your local machine. So please send your feedback and comments, so I can include this in PEAR as soon as possible :-) Best regards, Stephan
