array walk in an easy way for displaying view? [Solved] - El Forum - 11-16-2010

In my view i want to display multidimesional array data decently , i want total control over it so that i can show data in a table the way i want.
i have these 39 arrays in $mydata in the view. I'll give you an idea with var_dump($mydata)

Code:
array(39) 

{ [0]=> array(3) { [0]=> string(18) "Unit Name 1" [1]=> string(9) "Category Name 1" [2]=> string(20) "Course Name 1" }

 [1]=> array(3) { [0]=> string(54) "Unit Name 2" [1]=> string(15) "Category Name 2" [2]=> string(20) "Course Name 2" }

  [2]=> array(3) { [0]=> string(29) "Unit Name 3" [1]=> string(15) "Category Name 3" [2]=> string(20) "Course Name 3" }

.....

i tried

Code:
foreach($mydata as $row)

            {

            $row->unit_name;

            $row->category_name;

            $row->course_name;

            }

i got this error

Quote:Message: Trying to get property of non-object

then i tried this which worked

Code:
foreach($mydata as $row)

            {

                echo $row[0];

                echo "</br>";

                echo $row[1];

                echo "</br>";

                echo $row[2];

                echo "</br>";

            }

Is there any way to access my inner array items like this , because that makes more sense to me , or is there any easy way to display array elements ?

Quote:$row->unit_name;
$row->category_name;
$row->course_name;

You have an array, not an object. Also, they keys are numerical (0,1,2,etc) which is why $row[0] works and $row['unit_name'] wouldn't. One option would be to dynamically assign the row key's as variables like this.

Code:
foreach($mydata as $row => $value)

{

    $$row = $value;

}

"Variable Variables"

i am sorry i could'nt understand this concept.
does that mean this ?

Code:
foreach($mydata as $row => $value)

{

$$row = $unit_name;

$$row = $category_name;

$$row = $course_name;

echo $unit_name;

echo $category_name;

echo $course_name;

}

Something like this could work:

Code:
foreach($mydata as $row => $value) {

   $unit_name = $value[0];

   $category_name = $value[2];

   $course_name = $value[3];

   echo $unit_name;

   echo $category_name;

   echo $course_name;

}

Also, the variable being defined is always on the left, and the value to set is always on the right.

Or make the original array associative.

$temp = array(
[0] => array('name' => 'value'))

Then you can access is with $temp[0]['name'] etc.

I prefer this way of doing arrays as its easier for me / other developers to identify the information being accessed in the array.
