Multidimensional array function from seperate arrays

[Rmazin]

Hello,

I've tried to get help on this but a bit prematurely so I am trying again.

I have 2 arrays but I need to make them into a multidimensional array but the factors need to change using IF statements and I need this all done in a function for callback in Jpgraph.

Here is my code:

//the following 2 arrays are pulled from my DB and work
//determine size

$cirsz[0] = 'small';
$cirsz[1] = 'medium';
$cirsz[2] = 'large';

//determine color from these values
$circlr[0] =  23;
$circlr[1] = 20;
$circlr[2] = 18;

//breaksdown somewhere in the function

function SettingSet($cirsz, $circlr) {

global $cirsz; 
global $circlr; 
    // This callback will adjust the fill color and size of
    // the datapoint according to the data value
    $i = 0;
//get sizes
foreach($cirsz as $s){
if($s == 'small'){
$sz = 15;
}elseif($s == 'medium'){
$sz = 30;
}else{
$sz = 50;
}

if($circlr <= 25 && ($circlr >= 18.75)){
$col = "red";
}elseif($circlr < 18.75 && ($circlr >= 12.5)){
$col ="orange";
}elseif($circlr < 12.5 && ($circlr >= 6.25)){
$col = "yellow";
}else{
$col = "green";
}
$i++;
}
  return array($sz,"",$col); 
} 

I need the array which the function returns to look similar to this:

array(
$a[0] = 15 => "" => red;
$a[1] = 30 => "" => red;
$a[2] = 50 => "" => orange;
}

Thank You in advance for taking the time to help me.

      $col = "yellow";

      $col = "green";
    }

    $result[] = array($sz, "", $col);
  }

  return $result; 

}

      $col ="orange";
    }  elseif ($circlr < 12.5 && ($circlr >= 6.25)) {
      $col = "yellow";
    } else {
      $col = "green";
    }

    $result[] = array($sz, "", $col);
  }

  return $result; 

} 

Thank You. This is now returning these messages:

Warning: Missing argument 2 for SettingSet()

Warning: Invalid argument supplied for foreach()

$result is also returning as NULL

I think I figured out the problem but I'm not sure how to fix it.

This:

$result[] = array($sz, "", $col); 

is returning as this ArrayArrayArray.

Any ideas?

You should use var_dump() or print_r() if you want to view the contents of a variable, or the return value of a function. echo/print isn't suited to displaying arrays.

This is probably a good time for you to read a tutorial on php functions.

I have used all of the above. They all return as either NULL or nothing at all. If i echo $sz or $col within the function they return correctly for each increment of the respective arrays. I am also getting this error when i print_r($result) or callback the function: Fatal error: Unsupported operand types

post some code which demonstrates your problem.

I've made a few adjustments and now I have the array printing correctly when it's called back inside the function. When it is called from without using

print_r($result); It returns nothing just whitespace.
Using:
print SettingSet(); it calls back the word Array.

Code is below:

 function SettingSet() {   
 // This callback will adjust the fill color and size of   
 // the datapoint according to the data value     
  global $cirsz; 
  global $circlr;
  
 //$result = array();    
  //get sizes   
  $i=0;
  foreach ($cirsz as $s) { 
  
  if($s == 'small') {       
  $sz = 15;    
   } elseif ($s == 'medium') {      
    $sz = 30;     
    } else {      
     $sz = 50;     
     }     
//$sizefin = array($sz);
 if ($circlr[$i] <= 25 && ($circlr[$i] >= 18.75)) {     
     $col = "red";     
     } elseif ($circlr[$i] < 18.75 && ($circlr[$i] >= 12.5)) {    
      $col ="orange";    
       }  elseif ($circlr[$i] < 12.5 && ($circlr[$i] >= 6.25)) {      
        $col = "yellow";    
         } else {      
          $col = "green";     
          } 
         // $colfin = array($col);
          //$b = "";
         // $bl = array($b);
           $i++;  
           $result[] = array($sz, "", $col);
                      }  
            //print_r($result);  //uncommenting this line prints the array correctly.
            return $result; 
             } 

Thanks

print and echo are not suitable for displaying an array. You should use print_r() or var_dump() to display an array.

Your function returns an array.

print_r(SettingSet());

Odd, i tried that one, maybe i typo'd. Any idea what this means?

Fatal error: Unsupported operand types

That is what i am getting when inserting the value into the graphs using:

$sp1->mark->SetCallback("SettingSet");

The error message probably tells you where the error is(file and line)

it doesn't there aren't even close to 306 lines of code. Which is where it says the error is. I think it's something to do with the way the array is called back but I'm really stumped at this point.

It was originally built from this function they give as an example in jpgraph.

function FCallback($aVal) {
    // This callback will adjust the fill color and size of
    // the datapoint according to the data value according to
    if( $aVal < 30 ) $c = "blue";
    elseif( $aVal < 70 ) $c = "green";
    else $c="red";
    return array(floor($aVal/3),"",$c);
} 

The problem with using this function is that is scales to the Y axis values of the graph, I need it to scale to a piece of data that isn't represented in my graph.
