[PHP] Need some help with array sorting
Ahem *tap* *tap* is this thing on?
Hi everyone, my name is Will and I've been addicted to php for 3 months
and 21 days... *grin*
I'm hitting a bit of a brick wall in a current project - the answer is
probably quite simple, but I'm still newish to php and coding in general
so bear with me:
I have a multidim array which looks something like :
$blocks[0] = array("param1"=>"4","param2"=>"some other param")
$blocks[1] = array("param1"=>"3","param2"=>"some other param")
$blocks[2] = array("param1"=>"6","param2"=>"some other param")
And so forth
Fairly straight forward you say, my problem is that elements can be
inserted into the blocks array in no particular order and I need to sort
at the top level using the values in param1 - so my output should be:
$sorted_blocks[0] = array("param1"=>"3","param2"=>"some other param")
$sorted_blocks[1] = array("param1"=>"4","param2"=>"some other param")
$sorted_blocks[2] = array("param1"=>"6","param2"=>"some other param")
I've had a long hard look at the manual and all those obscure array
manipulation goodies (ksort, multisort, etc) and done some hunting on
phpbuilder and the like, but turned up zip - either I'm not
understanding the array functions properly, or this can't be done, or
there's a nifty trick for doing it which I havent figured out?
Ideally I'd like to be populating blocks using an sql query so I could
do an order by or some such upfront, but this world is anything but
ideal.
Any1 got 2c for me?
Thanks in advance
Will

Heh - I know how you feel. I'm an ex network tecchie fighting my way through a career change to web developer - spent some time messing with various scripting tools and so forth, but never really had any formal coding experience until I hit php - if you want some advice on learning php mine is spend the next few weeks/months just soaking up every tutorial you can lay your hands on - the best libraries are on phpbuilder, devshed and zend imho - altho webmonkey also has a couple of really 'beginner' ones (hello world country) you might want to start out with. Also one thing no-one ever really tells you about this is that one of the most important things to learn if you plan on building sites with php is not php - its html. I know this is a bit duh!, but seriously - php is about logical structures - and slapping together a few variables - it aint that hard once you get in the groove, but if you don't know your html well enough to handcode it and to deconstruct a fat mess of tags in your head and visualize what its going to end up looking like on screen - you're going to have a hard time coding scripts to generate the stuff. 0.02 - actual mileage may vary - insert coin to generate more bs Cheers Will > -Original Message- > From: Chad Winger [mailto:[EMAIL PROTECTED]] > Sent: 12 September 2002 03:34 PM > To: [EMAIL PROTECTED] > Subject: Re: [PHP] Re: Cry for help > > > I have no idea what that means, sorry :) > > My point for wanting to do this isnt because I really want to > make a list of the home teams or whatnot.

RE: [PHP] Re: Cry for help
Heh good so you're not a complete n00b then :P Luckily I had a fairly decent grounding in html and css as well when I got going - I'm just putting the finishing touches on my first serious project atm using OO style php which made the learning curve about 10 times steeper as I had no previous experience with an OO language and the OO tuts as you will find are pretty thin on the ground and of varying quality - thinking of writing a few myself when I get a breather :-) GL and happy reading :-) Cheers Will > -Original Message- > From: Chad Winger [mailto:[EMAIL PROTECTED]] > Sent: 12 September 2002 04:00 PM > To: [EMAIL PROTECTED] > Subject: Re: [PHP] Re: Cry for help > > > Html is something i do in my sleep :P thankfully I've been > good enough with it to make a decent living with it.

RE: [PHP] Need some help with array sorting
Thanks Timo
I figured if it was do-able it would be something like uasort, or uksort
or one of those, but my geek muscles arent quite up to that sort of flex
yet - any one mind giving me some clues as to how to get started using
these functions - the manual gets pretty vague in this area?
Thanks

RE: [PHP] a href...
Use & a href="bug_detail_user.php?id=$id&reporter_id=$reporter_id" Some reading around post methods and passing data between scripts might be in order to familarize yourself with all the syntax etc. Hope this helps --Will > -Original Message- > From: Meltem Demirkus [mailto:[EMAIL PROTECTED]] > Sent: 13 September 2002 02:57 PM > To: [EMAIL PROTECTED] > Subject: [PHP] a href... > > > Hi, > Iwant to send 2 variable by using a href like that: > > a href="bug_detail_user.php?id=$id?reporter_id=$reporter_id" > > > isnt this possible because it is taking the data id as > $id?reporter_id=$reporter_id... > > can anyone tell me how I can manage this.. > thanks.. > > meltem > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] can you get the name of an object from within it's own class?
Hehe why break your brain- give the class an id property - then you can
have a getid method and do something like this
$id = $this->getid();
$this->fpLog = fopen("$id.log","w+");
get_object_vars only seems to return properties so its not gonna help
you.
I'm currently working on an object thang as well and what ive done where
I have whole bunch of similar objects is to chuck them into a name=value
array as they get created so I can find them and fiddle with them again.
I have no idea if that helps you, or if its even good coding practice
(formal training - wots that?)
hey im also a n00b so don't take my word on it - actual mileage may
vary :-P
Cheers
Will
