  • php - usort or array_multisort?

    - by Simpson88Keys
    Trying to sort the array below by memnum in ascending order, and I'm a bit confused which is better to use... usort or array_multisort? I was thinking usort because it's multidimensional? Does anyone have an example of this? Array ( [0] => Array ( [memnum] => 3236467423 [mid] => 1104881300 [fname] => JOHN [lname] => DOE [add1] => OMITTED [add2] => [city] => CHESTERFIELD [state] => MI [zip] => 48051 [age] => 50 ) [1] => Array ( [memnum] => 3258467922 [mid] => 1105121457 [fname] => JANE [lname] => DOE [add1] => OMITTED [add2] => [city] => CHESTERFIELD [state] => MI [zip] => 48051 [age] => 50 ) [2] => Array ( [memnum] => 3237769108 [mid] => 1104489312 [fname] => BOB [lname] => DOE [add1] => OMITTED [add2] => [city] => CHESTERFIELD [state] => MI [zip] => 48051 [age] => 50 ) )

  • MySQL LEFT JOIN, INNER JOIN etc, complicated query, PHP + MySQL for a forum

    - by Sven Eriksson
    So I've got a little forum I'm trying to get data for, there are 4 tables, forum, forum_posts, forum_threads and users. What i'm trying to do is to get the latest post for each forum and giving the user a sneak peek of that post, i want to get the number of posts and number of threads in each forum aswell. Also, i want to do this in one query. So here's what i came up with: SELECT lfx_forum_posts.*, lfx_forum.*, COUNT(lfx_forum_posts.pid) as posts_count, lfx_users.username, lfx_users.uid, lfx_forum_threads.tid, lfx_forum_threads.parent_forum as t_parent, lfx_forum_threads.text as t_text, COUNT(lfx_forum_threads.tid) as thread_count FROM lfx_forum LEFT JOIN (lfx_forum_threads INNER JOIN (lfx_forum_posts INNER JOIN lfx_users ON lfx_users.uid = lfx_forum_posts.author) ON lfx_forum_threads.tid = lfx_forum_posts.parent_thread AND lfx_forum_posts.pid = (SELECT MAX(lfx_forum_posts.pid) FROM lfx_forum_posts WHERE lfx_forum_posts.parent_forum = lfx_forum.fid GROUP BY lfx_forum_posts.parent_forum) ) ON lfx_forum.fid = lfx_forum_posts.parent_forum GROUP BY lfx_forum.fid ORDER BY lfx_forum.fid ASC This get the latest post in each forum and gives me a sneakpeek of it, the problem is that lfx_forum_posts.pid = (SELECT MAX(lfx_forum_posts.pid) FROM lfx_forum_posts WHERE lfx_forum_posts.parent_forum = lfx_forum.fid GROUP BY lfx_forum_posts.parent_forum) Makes my COUNT(lfx_forum_posts.pid) go to one (aswell as the COUNT(lfx_forum_threads.tid) which isn't how i would like it to work. My question is: is there some somewhat easy way to make it show the correct number and at the same time fetch the correct post info (the latest one that is)? If something is unclear please tell and i'll try to explain my issue further, it's my first time posting something here.

  • PHP Object conversion question

    - by karlthorwald
    I am converting from JSON to object and from object to array. It does not what I expected, can you explain to me? $json = '{"0" : "a"}'; $obj = json_decode($json); $a = (array) $obj; print_r($a); echo("a0:".$a["0"]."<br>"); $b = array("0" => "b"); print_r($b); echo("b0:".$b["0"]."<br>"); The output here is: Array ( [0] => a ) a0: Array ( [0] => b ) b0:b I would have expected a0:a at the end of the first line.

  • Retrieve part of a MySQL column with PHP

    - by Gerardo Marset
    For instance, if I have the following table: +----+---+----------+ | id | a | position | +----+---+----------+ | 0 | 0 | 0 | | 1 | 0 | 1 | | 2 | 1 | 4 | | 3 | 1 | 9 | | 4 | 1 | 6 | | 5 | 1 | 1 | +----+---+----------+ and I want to get an array that contains the first 100 values from position where a is 1 in ascending order, what would I do? Im guessing something like this: $col = mysql_fetch_array( mysql_query(' SELECT `position` FROM `table` WHERE `a`="1" ORDER BY `position` ASC LIMIT 100 ')); I'd expect to get the following array: +-------+-------+ | index | value | +-------+-------+ | 0 | 1 | | 1 | 4 | | 2 | 6 | | 3 | 9 | +-------+-------+ but it doesn't work. ¿What should I do to make it work? Thanks

  • php class extend - run something before running parent function

    - by Patrick
    Hi, say I have this class: class animal { function noise() { print 'woof'; } function move() { print 'moved'; } } class dog extends animal { } What I would like to do is when i run $dog-noise() or $dog-move(), it would run something first prior to calling animal class's noise/move. Is this doable? Like maybe logging the function call. If not with class extend, what else can I use to achieve this? Thank you!

  • PHP + GD: imagetruecolortopalette not keeping transparency

    - by AlexMax
    I am using GD to output an image that is a truecolor+alpha channel PNG file using imagepng just fine. However, I would like to have the ability to also output an ie6-compatible 256-color PNG as well. According to the official documentation for imagetruecolortopalette: The code has been modified to preserve as much alpha channel information as possible in the resulting palette, in addition to preserving colors as well as possible. However, I am finding that the results of this function do not properly preserve any transparency at all. I used this firefox image with text superimposed on top of it as a test, and all the function did was give me a white background and a weird dark blue border. I know that I can't hope to preserve the full alpha channel, but surely this function would at least pick up on the transparent background. Is there something I'm missing? Are there any alternative approaches that I can take?

  • Math - Adding with PHP

    - by Wayne
    Basically I can't get it right. I need something like this: if($p == 1) { $start = 0; $limit = 16; } The numbers must add on depending on the value of the $p, e.g. if $p is 5 then the values of $start and $limit would be: if($p == 5) { $start = 64; $limit = 80; } The math is to add 16, depending on the value of $p. Thanks.

($config === NULL) and $config = Kohana::config('email'); Is that the equivalent of if ($config === NULL) { $config = Kohana::config('email'); } Is this commonplace? Would I expect other developers looking at my code if I used that first way to instantly know what it was doing?
