return multiple array through json in codeigniter - php

Question

I want to return multiple array using json in codeigniter like this :
{
"countData"
[
{"flag":1,"count":3}
{"flag":0,"count":0}
{"flag":1,"count":2}
]
}
I already tried :
$faqdata=array(
'count' => $faqdata['countdata']['resultdata']['count'],
)
$listfaqcount['count_Data'][]=$faqdata;
$listfaqcount['flag'] =1;
$j_r=json_encode($listfaqcount);
echo $j_r;
Like this way for two more array .flag would be zero in else condition which I didn't mention here.
How can I do this? Please help.
Thanks in advance

Answer 1

You can do something like this
$listfaqcount['countData'][0] = array(
'flag' => 'flagValue',
'count' => 'countValue'
);
While you looping you change the index with your key like that
$listfaqcount['countData'][1] = array(
'flag' => 'flagValue',
'count' => 'countValue'
);
and so on and while you encoding you can do like this
echo json_encode($listfaqcount);

You need something like array_push
$array['countdata'] = [];
create our sample array sets
$somearray1 = ['flag'=>9,"count"=>5];
$somearray2 = ['flag'=>6,"count"=>6];
$somearray3 = ['flag'=>5,"count"=>7];
$somearray4 = ['flag'=>4,"count"=>8];
Basically what happens here is everytime you loop you push the array inside $array['countdata']
array_push($array['countdata'], $somearray1); //loop 1 format and push
array_push($array['countdata'], $somearray2); //loop 2 format and push
array_push($array['countdata'], $somearray3); //loop 3 format and push
array_push($array['countdata'], $somearray4); //loop 4 format and push
Print the result beautifully or prettily
print_r(json_encode($array,JSON_PRETTY_PRINT));
result would be
{
"countdata": [
{
"flag": 9,
"count": 5
},
{
"flag": 6,
"count": 6
},
{
"flag": 5,
"count": 7
},
{
"flag": 4,
"count": 8
}
]
}
this is just an example you could push your own formatted array.
