<0> EDarkness, Start from http://php.net/tutorial
<1> rapha: Very Likely
<2> EDarkness: Although, if your *DATABASE* is saying it's not an int, that's probably because you quoted the value when p***ing it into the query.
<3> What I did was use a single = so all values got changed into "" since I was checking for a blank value.
<3> Changed it to == and everything is working.
<2> EDarkness: Instead of using '== ""', try using isset() or 'strlen() > 0'
<3> Okay.
<3> Everything is working. Thanks a bunch for the help. It's 3am and I'm goin' to bed. You guys have a good one. :)
<4> Im back with another question, I was wondering if and how you could add an x ammount of currency to a number every 24 hours?
<4> or x ammount of time?
<5> what do you need it for guitar
<5> you could use cronjobs, but most of the time this is not needed
<4> I am just working on money calculations for a future web rpg project. http://hashphp.org/pastebin?pid=6235 for an example.
<4> I want to make it so every x ammount of time the total increases by x ammount
<5> ask yourself if it's really needed to have the amount updated over an x-period of time
<5> what about updating the amount of money when the user next logs in?
<5> if you keep track of users actions, you can store when a user left your page the last visit
<4> How would you go about doing that?
<5> when he logs in again, you'll know the current time
<5> calculate how many periods have p***ed, translate this in a certain amount of money and update the account
<5> easy as that
<4> how would you determine when the user left?
<5> this is far more efficient then updating for EVERY user EVERY 24 hours
<5> when a user clicks a link you simply update a datetime field in the database
<5> the last click is right before he left your website
<2> I'm not convinced that Ruud's model is correct for your use case, guitarsauce. Do you want all users to have their value incremented at the same time?
<5> i am :)
<4> yes, that would be helpful, but i would also like to be able to change individual accounts
<2> guitarsauce: If you want to update ALL accounts, a cronjob is the best way.
<4> cronjob?
<5> it's like windows task schedular
<5> but for *nix
<4> ok, gotcha.
<6> :O
<4> but i dont run on a *nix system
<4> so could i just use the task schedular?
<2> guitarsauce: Then use your platform's equivalent
<5> then you can use the windows task scheduler
<5> i still think you're going the wrong way here tho, but it's up to you ^^
<2> guitarsauce: Also, note that: "if ($_POST['foo'] == '') { $foo = 0; } else { $foo = $_POST['foo'] }" can be more easily spelled: "$foo = max(0, $_POST['foo']);"
<5> hey, thats a nice one TML, thanks for that :)
<2> Just make sure you put the 0 first. It coerces the type for the remainder of the comparison.
<5> and do a isset first, but that should be clear :)
<4> Is there any good PHP/Mysql books that any of you would recomend?
<2> Ruud: You only need an isset() if you want your code E_ALL safe. max(0, NULL) does the right thing.
<2> guitarsauce: php.net/manual
<5> still, it's good practice
<5> $foo = isset($_POST['foo']) ? intval($_POST['foo']) : 0;
<4> ok, thanks everyone.
<5> good luck
<2> guitarsauce: Nearly every PHP book out there is a reprint of that content, with some author going on ad nauseum in between chunks of useful info.
<2> Ruud: I'm of the opinion that my example delivers far more in readability than it may lose in...whatever it is that you're concerned about.
<4> So no point to buy a book that just covers the core functions of PHP?
<2> guitarsauce: No
<5> we have php.net for that :)
<5> well, the manual there
<7> And dont buy a book that teaches you PHP4
<8> dont buy a book
<8> its all on the internet for free
<7> Advanced PHP Programming was a great book
<7> I use it as a reference all the time
<8> http://uk2.php.net/manual/en/ is also great
<9> http://www.php.net/manual/en/ not everyone's in the UK :P
<7> Yeah, but old George has some nice tricks up his sleeve ... I'd recommend it

<8> if you include() a file somewhere in a script, is it posible to un-include it?
<10> whats a super dooper php gallery library? very simple.. so a photographer can upload a dir and have a customer using p***word access it?
<11> gallery?
<12> Bizzeh, how does that make sense?
<10> mmm
<8> Scorpmoon: give me a week and KATH is going to be ready
<10> a week is due my deadline
<10> not considering the bugs you want me to remove :)
<5> lol
<8> mybadluck: well, i wanna while(readdir()) { include(); do stuff with it; uninclude(); }
<8> since the files ill be including have the same named functions
<7> Bizzeh : Then thats just bad design
<7> Bizzeh : You need cl***es then
<7> No files with functions
<13> will: if ($foo != NULL) take more cpu resource than if (!$foo); ?
<14> morning all :)
<15> i got an arrMod[install][25]==1 and now intval(array_keys($arrMod)) returns 1 instead of 25. did i think something wrong?
<7> krisp : I dont know about resources ... but !$foo is faster
<14> kon: array_keys() returns an array of keys, you then trying to convert and array to an integer
<15> oh
<15> so if i just wanted the first key what would be the best way to do so
<16> krisp: !== null is fastest
<16> krisp: but they both do different things
<17> hi.. can someone help me with a bit of smarty scripting ?
<16> are you trying to see if the variable is set? use isset()
<16> oghran; hell no, #smarty
<17> :) just checking
<17> thank you
<14> kon: array_shift()? But have a look in the array section of the php manual, there might be a better way depending on your exact needs.
<15> Lomat: thanks alot, yep i just saw this, in combination with reset() this is perfect for my need, thank you!
<18> hi all can any body help me in file habdling for php?
<16> lamers_inn: I don't know, ask the question and we'll find out :)
<18> hi all can any body help me in file habdling for php?
<19> Hmmm..
<16> lamers_inn: ...
<5> that's his question
<16> hehe
<5> the answer is yes
<19> Probably.
<20> TML: Angel-SL|: is there some documentation on how you can change an app to work under PHP5, what needs to be changed and so?
<16> rapha: have you spent more than half a second looking?
<20> aidan: I haven't been able to find any documents specifically for this, and yes, I have spent more than half a second. Excuse me please if I offended you in any way, sir.
<16> rapha: http://www.php.net/manual/en/migration5.php
<20> Thanks
<16> rapha: it's on the front page of the manual
<20> aidan: Sometimes you're just blind ... isn't that why there's so many people in the world so that we can help each other with our blindness?
<20> isn't that why there are, even
<16> rapha: and please don't address your questions to specific people in the channel unless you're actually engaged in a conversation, you're more likely to get help and it's less annoying for those people (who are not even here)
<16> rapha: yes, sometimes we're just blind, aslong as you've looked we don't mind :)
<16> I found the link googling for "php4 to php5 migration"
<18> i want to make a file on sever and want to make some checks according to that .txt file
<18> here is an example
<20> aidan: these specific persons had answered me before, although that was quite some minutes ago. I think after more than 10 years or so I should know the basic IRC rules.
<18> the .txt file should save the number of times a web page is accessed
<20> aidan: You have to know the word migration in order to be able to enter that search query. I'm not a native speaker.
<21> hello... how do I discover the mime type of a file? i want to set the content-type header correctly before I send the data. I don't know if this is an apache question though..
<18> and at 100th time it should siplay some message
<16> rapha: well you speak very well :)
<18> can u help me
<16> cb921: php.net/fileinfo
<21> ah thanks
<20> aidan: thanks :-) ... doesn't give me an endless vocabulary tho.
<16> lamers_inn: file_get_contents, file_put_contents or fopen/fwrite/fclose with flock.
<21> searching mime didn't give me any results
<22> lamers_inn: file_get_contents() fputs() fopen() and $var++
<20> aidan: but thanks for the addition (to my vocabulary, that is) :-)
<16> cb921: yeh it's a tricky one, the mime_content_type function has been deprecated and the new extension is quite tricky to use
<16> rapha :)
<22> fileinfo() didn't seem that hard to run ...
<16> I couldn't get the damn extension to work for me
<21> php.net/mime_magic ?
<21> nm
<22> I cheat.
<22> urpmi php-fileinfo
<16> oops
<22> or was it urpmi php-pear-fileinfo
<16> http://php.net/finfo
<18> <16>: u there?
<23> All: How can I disable that php always overwrite my meta-tag "Content-Type"
<16> oops, that's wrong too
<16> Kako: php.ini and httpd.conf both have options
<22> In all honesty if you know the extension is the right type, just use a case on the extension.
<22> It's probably not the 'right' way to do it.
<23> aidan: default_mimetype = "text/html"
<23> default_charset = "UTF-8"
<23> but allways set it again to iso-8859-1
