PHP - Multidimension Array + In_array

<?php


$menu =  array(                  '22' => array (

                                    'title'=>'Businesses'

                                    ,'busstype'=>array(

                                                   5=>'Printers'

                                                   ,2=>'Bookshops'

                                                   ,6=>'Publishers'

                                                   ,8=>'Uniform Distributors'

                                                     )

                                    )

                           ,21 => array (

                                    'title'=>'Academic'

                                    ,'busstype'=>array (

                                                   5=>'Academy'

                                                   ,6=>'Primary'

                                                   ,7=>'Polytechnic'

                                                   ,11=>'University'

                                                     )

                                 )

                           ,'Events' => array (

                                    'title'=>'Events'

                                    ,'busstype'=>array (

                                                   3=>'Music'

                                                   ,4=>'Road shows'

                                                   ,6=>'Sports'

                                                   ,6=>'Yoga'

                                                     )

                                 )



) ;



I have a dynamically created menu as above. How would i sort on the 'busstype' homogenously and print it while maintaing the key.

Results should be like

<a href="search.php?listing=21&busstype=5">Academy</a>

<a href="search.php?listing=22&busstype=2">Bookshops</a>

.......

<a href="search.php?listing=Events&busstype=6">Yoga</a>

?>

I'm having an issue with building a multidimensional array via a for (....)
the array should look like the example
any help would be much, much appreciated
thanks siouxx
   
array   
["username"] = "steve"
   array
      ["item"] = "12345"
      array
         "model" = "some model"
         "quantity" = "36.2"
         "details"
         array
            0 = "detail 1"
            1 = "detail 2"
            2 = "detail 3"

["username"] = "steve"
   array
      ["item"] = "000257"
      array
         "model" = "some other model"
         "quantity" = "77.8"
         "details"
         array
            0 = "detail 1"
            1 = "detail 2"

["username"] = "bob"
   array
      ["item"] = "45678"
      array
         "model" = "other model"
         "quantity" = "99.5"
         "details"
         array
            0 = "detail 1"
            1 = "detail 2"
            2 = "detail 3"
            3 = "detail 3"

the array return by sql looks like this
Array

I have whiled my way through any number of forums and help pages so far. However, since I am not quite comfortable yet with PHP, I am not sure which option I have been given would be the right one.

What I am trying to do:  Create the source for a set of drop-down menus. The dropdown menu has columns, and then a H2 and P that go in each column, in varied numbers, so you have
column1, h2 p; h2 p; h2 p
column2, h2 p; h2 p
etc....make sense? I am using an MySQL table as source so I can have a little CMS dashboard where I can change these and other values on the fly.

So I have a MySQL table where I have a field that identifies the column (page name), and then values to fill the h2 and p tags. I.E.:
page_name, content_title, content_text

The idea, therefore, is to use PHP to figure out what the column names (that are repeated) in the mysql table and then create the dropdown based on the value in the subsidiary fields. Output is as a string in a variable value that is output via return ();

My best estimation of how to do this is to use php to create a multidimensional array from the query result, where the first column is the page_name, followed by an array, the array being the remainder of the information.

Based on information scrounged from other sources, I have come up with this so far:


$query = "SELECT * FROM tbl_mainmenu WHERE mainmenu_type = '$mmtype'"; // what the query is
$result = mysql_query ($query, $dbc); // connect to database and run query, setting the the result to dummy array variable '$result'

// establish the multidimensional array

$mmcontent_array = array ();

//create the array where the values are content page and associated values in an array per each content page

while ($result = mysql_fetch_assoc ())

{

$page_name = $result['content_page'];

$mmcontent_array['content_page'] = $result;

}

foreach ($mmContent_array[] as $key=>$value)

{

foreach ()

{

$tmpelements[] = '<div class="col_2"><h2>' . $element[content_title] . "</h2>\n<p>" . $element[content_text] . "</p>\n</div>";

$elements = implode("\n",$tmpelements) . "\n"

}

$tmp[] = '<li><a href="#" class="drop">Products</a><!-- Begin Products Item -->\n<div class="dropdown_2columns"><!-- Begin 2 columns container -->' . $elements . 'whatever tags will close this')

}


Am I even in the ballpark?

I am not sure which way to nest the foreach ()'s. The example I was working from used echo ()'s, and I am not sure if using $variable = implode () makes the task different.

As a start, I am just wondering if I am creating the multidimensional array correctly?

Can someone please help me figure this out:

I have a normal text file with 3 lines in it, every line contain one date i.e 12112011 (12.11-2011). I put the content of that file in an array, and want to compair the dates in the text file against the date generated from the loop. Problem is, i can only get a match for the last date listed in the text file no matter what.. If i have 4 dates in the file, it only style the last date.

Thanks!

--- CODE SNIPPET ---

$day_num = 1;
$days_in_month = 30;
$month = 11;
$year = 2011;

//Access the file containing already taken dates and load them in an array:
$date_array = file("test.txt");

//count up the days, untill we've done all of them in the month and check them against the dates in the text file:
while ($day_num <= $days_in_month) {

   // Set the variable $date to be checked against the content of the array:
   $date = $day_num . $month . $year;
   
   if (in_array($date, $date_array)) {
               echo "<td class='color_green'>$day_num</td>";
      //print_r($date_array);
   }
   else {
      echo "<td>$day_num</td><br />";
   }
   
   $day_num++;
}

Hi all.

I've got this bit of code:

   $needles=array(`.`,`..`,`css`,`php`,`input_forms`);

   $t1=scandir($_SERVER['DOCUMENT_ROOT']);
   foreach($t1 as $t1_value){
      if(!is_dir($t1_value)){
         unset($t1[array_search($t1_value,$t1)]);
      }else{
         unset($t1[array_search($needles,$t1)]);
      }
   }


As you can see, I'm trying (in the else statement) to array search $t1 for everything in $needles, then unset the matches from $t1.  But its not working and I'm not sure why.  I also tried...

unset($t1[array_search(in_array($needles,$t1),$t1)]);


But that doesn't work either.  It only removes the "." directory from the array.  Any ideas on what's going wrong?
