I'm writing a simple telnet client library. I open sockets using fsockopen() and read and write to the socket using fgetc() and fwrite(). I use fgetc() instead of fread() to handle Telnet special commands and options like (IAC, ...). the problem is that most of times I'm reading from the socket, it takes too long to return. as I have pr...

I really don't get that: Some platforms have some kind of "persistent" login sessions. Like Stackoverflow and many other boards and platforms. I've logged in here a month ago. And even if I quit my browser totally and have another internet connection with different IP, I come back here with no login. I can't belief that's just done with...
Being as stubborn as it gets, I'm building my own PHP-based CMS and framework (named RAmen/FSM just for the kicks) that has been deployed multiple times for my customers. Now, I'm going to develop a support ticket application for it that I will deploy on a 'central' server for convenience of maintenance. Now, I've looked into SOAP servi...
That question may appear strange. But every time I made PHP projects in the past, I encountered this sort of bad experience: Scripts cancel running after 10 seconds. This results in very bad database inconsistencies (bad example for an deleting loop: User is about to delete an photo album. Album object gets deleted from database, and t...
example: making a payment transfer from user A to user B. Account of user A: -10 USD Account of user B: +10 USD if there is an transaction, and something goes wrong, everything gets undone. So with transactions it will not happen that account of user A gets decreased by 10, while account of user B does not get increased by 10. I know t...
Within a php/mysql system we have a number of configuration values (approx 200) - these are mostly booleans or ints and store things such as the number of results per page and whether pages are 2 or 3 columns. This is all stored in a single mysql table and we use a single function to return these values as they are requested, on certain ...
2 of my urls, for example www.abc.com and www.def.com point to the same .php file. I have some text on that target page that needs to be dynamically changed depending on whether it came from www.abc.com or www.def.com. Can this be done? How? ...
I accept file uploads from users. Each file has a pointer in the db which has info on the file location in the filesystem. Currently, I'm storing the files in the filesystem non categorically, and each file is currently just named a unique value. All categorisation and naming etc is done in the app using the db. A factor that I'm concer...
There is basic persistence of Javascript vars/etc. You call a function/method, and the next time you call that same function/method, it is holding the data from the last time. You can delete the vars when you are done with them, but that removes the advantage of using the code again for that instance. So what is the proper way to write...
$i=0; while ($row=mysql_fetch_assoc()) { if ($i==0) echo "First" $i++; } Access directly to mysqli pointer? a php class like's Iterator? Thanks. ...
I am trying to load an XML file from a different domain name as a string. All I want is an array of the text within the < title >< /title > tags of the xml file, so I am thinking since I am using php4 the easiest way would be to do a regex on it to get them. Can someone explain how to load the XML as a string? Thanks! ...
I have two functions, makeKey() and keyExists(). makeKey() simply generates a 5 digit random alphanumeric key, keyExists() accepts this key as its only argument, and looks up in a table, returning true/false depending on whether it exists. I need to do something very simple but I cannot figure out the quickest way of doing it. I just...
I was under the impression that FastCGI allowed you to kinda load in your web app once, and then you just "provide" FastCGI with some function, like myHandleHTTPRequest($url), that would then be called whenever a request came. This way you'd get much better performance as your app is ready in memory all the time, right? But I'm starting...
I'm trying to create a directory and I have two tables, entry and location. Each entry will be able to have multiple locations so I'm assuming the best idea (correct if wrong) is to create a third table where I specify 'links'. Example: Marly:France Karla:Argentina Smith:USA Katie:France Smith:United Kingdom Katie:USA When I want to l...
How do you build your own FastCGI interface in PHP? I'd like to do something similar to what they're doing in Perl, but in PHP. Is it even possible? Would it be faster? (That is, I'd like to be able to load a web app framework once into memory, and then just have FastCGI call a method I provide for every request. So not the more generi...
I am not totally new to PHP or XML but I am 100% new to paring XML with PHP. I have an XML string that has several nodes but the only ones I am insterested in are the < keyword > nodes which there are an uncertain number of each containing a phrase like so: < keyword >blue diamond jewelry< /keyword > for example say the string looked lik...
Hi, I've been wondering why would I use Exceptions in my PHP. Let's take a look at a simple example: class Worker { public function goToWork() { return $isInThatMood ? // Okay, I'll do it. true : // In your dreams... false; } } $worker = new Worker; if (!$worker->goToWork()) { if (date('l',time()) == 'Sunday') echo "F...
I am new to web programming, and I am developing a simple appointment app with PHP + MySQL. Is there a simple way to add a background process on a timer (to send out daily appointment reminders, for example)? This could be done easily in another language, but I want it to run on shared hosting with only PHP. ...
