[PHP] WDDX and binary data
Despite the fact that PHP's WDDX functions don't support a binary type,
most binary data comes through just fine, and in fact, the WDDX serialize
function can encode certain types of binary data, such as a null
character: char code='00'/
But the deserialize process dos not retain these characters. Is this a
bug in PHP's implementation of WDDX, or is there perhaps a workaround
available?
Here's some example code that shows a WDDX packet of encoded binary data.
The packet itself contains all of the binary data, including null
characters, etc. The deserialized() string, however, does not.
?php
$fp = fopen(http://www.php.net/gifs/php_logo.gif,r;);
while (!feof($fp)) {
$str .= fread($fp, 4096);
}
$packet = wddx_serialize_value($str, php_logo.gif);
Header(Content-Type: image/gif);
$str = wddx_deserialize($packet);
echo $str;
?

Re: [PHP] Storing serialized classes in database
When you serialize() an object in PHP, it only stores the properties, not the methods. This way you can change any of the methods in your class definitions, or add new properties, and when the data is unserialize()d, it will fit into the new class definition. The latest (development) version of Pecos (http://pecos.screwdriver.net/) (which should, incidentally, be released later today or tomorrow) has moved from using entirely serialized() data to having a seperate table for storing properties. Basically, we loop through the object using get_object_vars() and store each property (serialized() only if it was an array or another object) seperately in a seperate field. This approach allows you to search by property rather than having to do a full-text search of the serialize()d data (or even worse, loading up each object and searching through it manually). -- /chris/ On Monday, July 9, 2001, at 10:58 AM, Michael Champagne wrote: We are writing a series of applications which will store a user 'profile' between sessions as a serialized object in our Oracle database. We're storing data like the output format a user prefers file downloads in and things like that. If have to add certain things to this class, I'm assuming the serialized objects in the database become unusable. Does anyone have a good solution for this? I suppose we could go through the database and somehow convert these serialized 'profiles' to meet the new class spec. How much of a hassle is that?

[PHP] Zeev via Babelfish
I quite enjoyed the interview at http://www.dynamicwebpages.de/90.interview-zeev-suraski-linuxtag2001.php translated via babelfish. A tasty morsel: Also the attempt to make PHP the egg-laying woolly milch sow is not my opinion after the actual target for PHP. -- Zeev Suraski (translated from German to English via babelfish) I'm sure that I agree wholeheartedly. Maybe. -- /chris/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] Printable Report Generator
If the browser supports CSS, you can define pagebreaks when it is printed. There is an excellent article at: http://www.stars.com/Authoring/Languages/XML/BeginningXHTML/printing.html It won't work in all browsers, but it gets the job done often enough.

rest of code
if (!file_exists(userfile)) {

is a bit cleaner. I'd use unlink(userfile1) rather than system(rm
userfile1) just to be pretty.

While that works great, it seems to over-write the hard returns. This has hurt the format and readability of my information. ie. text file: This is a test output: This is a test is there someway to get readfile to recognize returns in the file? Thanks in Advance.. Ray Sounds like you are displaying the text as HTML. You can either surround the data with pre tags, or use the nl2br() function to convert each new line to a br tag. -- /chris/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

If you want to get the current uptime in Linux without a system() call, you should be able to fopen() the /proc/uptime file. The first number is the number of seconds the machine has been up, the second is the number of seconds the machine's processes have been idle. -- /chris/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
