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;
}
}

Answer 1

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?

Answer 2

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];
}
}
