Loading a Multidimensional Array

Client Joined: Oct 07, 2003 Posts: 735 Location: Ohio

I have this graph that I am STILL working on.

I made an array and am loading data into it. I want to then extract the data and use this data to graph.

The count of descriminator values is on the Y axis and the ranges are the X axis.

Here is what the array looks like.

Code:

$data = array("nP4_nP31" => array(


   


      "range" => "-.4 to -.31",   


      "descri" => 0),     


      


                  "nP3_nP21" => array(   


      "range" => "-.3 to -.21",   


      "descri" => 0), 


  


                  "nP2_nP11" => array(  


      "range" => "-.2 to -.11",   


      "descri" => 0), 


  


                  "nP1_nP01" => array(  


      "range" => "-.1 to -.01",   


      "descri" => 0), 


     


                 "P0_P10" => array(  


      "range" => ".0 to .10",   


      "descri" => 0), 


     


                 "P11_P20" => array(  


      "range" => ".11 to .20",   


      "descri" => 0), 


     


                 "P21_P30" => array(  


      "range" => ".21 to .30",   


      "descri" => 0),


     


                 "P31_P40" => array(  


      "range" => ".31 to .40",   


      "descri" => 0), 


     


                 "P41_P50" => array(  


      "range" => ".41 to .50",   


      "descri" => 0), 


     


                 "P51_P60" => array(  


      "range" => ".51 to .60",   


      "descri" => 0),


     


                 "P61_P70" => array(  


      "range" => ".61 to .70",   


      "descri" => 0), 


     


                 "P71_P80" => array(  


      "range" => ".71 to .80",   


      "descri" => 0), 


     


                 "P81_P90" => array(  


      "range" => ".81 to .90",   


      "descri" => 0),      


  


      );

I know how to populate the discri_data but how do I load the range_data with these values

.81 to .90

Code:

$chart = $db->sql_query("SELECT `discri` FROM question_stats WHERE quiz_id = '$qid' ORDER BY `discri`");    


while( $row = $db->sql_fetchrow($chart)) {    


    $discri = $row['discri'];      


   


if ($discri >= -.40 AND $discri <= -.31){


$discri_data['nP4_nP31']['descri'] += 1;


$range_data['nP4_nP31']['range'] = ;


}

If this...

Code:

$range_data = (array_keys($discri_data));





echo"<pre>";


print_r ($range_data);


echo"</pre>";


die();

gives me

Quote:

Array
(
[0] => nP2_nP11
[1] => nP1_nP01
[2] => P0_P10
[3] => P11_P20
[4] => P21_P30
[5] => P31_P40
[6] => P41_P50
[7] => P51_P60
)

Then I don't understand why I can't get these values.

Code:

foreach ($range_data as $key => $range){


    $ranges[] = $range;    


}

I need to do this $x->set_labels($ranges);

So that $ranges is displayed as my X axis.

*bump*
have you resolved this? I'm having some issues with two-dimensional array.
here is the example of what i'm talking about

Code:

$SKILL_ID = array (


'a touch of guile'=>2357,


'accumulated pain'=>1052,


'aegis (pve)'=>257,


'aegis (pvp)'=>2857,


'aftershock'=>174,


'aggressive refrain'=>1774,


'agonizing chop'=>1403,


'agony (pve)'=>2205,...}

Code:

$SKILL_ARRAY = array (


2993=>


array (


'name'=>'Predatory Bond (PvP)',


'chapter'=>2,


'profession'=>'Ranger',


'prof'=>'R',


'attribute'=>'Beast Mastery',


'attr'=>'bea',


'type'=>'Shout',


'ty'=>'sh',


'energy'=>10,


'adrenaline'=>0,


'eregen'=>0,


'sacrifice'=>0,


'casting'=>0,


'recharge'=>30,


'pve_only'=>0,


'elite'=>0,


'desc'=>'For 5..20 seconds, attacks by your animal companion heal you for 1..31 Health.',


'name_id'=>'predatory bond (pvp)',


),...

for example , I would like to be able to search for specific attribute in the array. eg. , create a search box in which I can search for 10 'energy' and it gives me a list of the skills with 10 'energy'.
I already know how to search for 'name'
would be this

Code:




/*search form above which returns a value for $skill , e.g. $skill = $SKILL_ID['a touch of guile'];// $skill=2357; /*


foreach($SKILL_ARRAY[$skill] as $cle=>$valeur) 


    { 


    echo $cle.' : '.$valeur.'<br>'; 


    }

which returns

Quote:

name : A Touch of Guile
chapter : 4
profession : No Profession
prof : ?
attribute : Norn rank
attr : nor
type : Hex Spell
ty : he
energy : 5
adrenaline : 0
eregen : 0
sacrifice : 0
casting : 0.75
recharge : 15
pve_only : 1
elite : 0
desc : Target touched foe takes 44..80 damage. If target foe was knocked down, that foe cannot attack for 5..8 seconds.
name_id : a touch of guile
