How do i display the chart_data in php

      $arr=json_decode($row[0],TRUE);

         var_dump($arr);

         foreach($arr as $row)
{
       foreach($row['chart_data'] as $k)
       {
             echo $k['Rank'];
             echo $k['Branch'];
       }
}

EDIT:

for ($x=0; $x<=count
($arr['chart_data']); $x++) {

foreach($arr['chart_data'][$x] as $key=>$val)
{


  echo $val;
}
}

format the array please.

That's not readable it doesn't even indent.

You are having 2 foreach calls.

The first one passes all keys of the outer array, amongst which chart_data.

The second one looks at the children of the outer array, and looks for chart_data in each child. But is obviously not finding any.

Change your code to this:

$arr=json_decode($row[0],TRUE);
foreach($arr['chart_data'] as $k){
    echo $k['Rank'];
    echo $k['Branch'];
}

edit:

I see. (Thanks for indenting your array) Your problem is off course that $arr['rank']and $arr['branch'] don't exist. They are mere strings inside $k[0] and $k[1] and themselves don't contain any other data.

What would you have like to see outputted?

Maybe this is solution.

$arr = json_decode($row[0],TRUE);

foreach($row['chart_data'] as $chart_data)
{
    foreach($chart_data[0] as $k)
    {
        echo $k['Rank'];
        echo $k['Branch'];
    }
}

Update :

Rank, Branch is values. Your array is bad format.

$arr = json_decode($row[0],TRUE);

foreach($row['chart_data'] as $chart_data)
{
    foreach($chart_data[0] as $k)
    {
        echo $k[0];
        echo $k[1];
    }
}
