How to append data into each sub-Array of an array - php

Question

I have an php array format:
[0] => Array
(
[post_id] => 37
[post_title] => الأَبْجَدِيَّة العَرَبِيَّة
[post_image] =>
[post_status] => 1
)
[1] => Array
(
[post_id] => 36
[post_title] => TEST open for text
[post_image] => post_1463052793.jpeg
[post_status] => 1
)
[2] => Array
(
[post_id] => 35
[post_title] => Hey Sushovan
[post_image] => post_1463038438.jpg
[post_status] => 1
)
Now, I want to append an extra index with value. For this, I am using this code:
$all_data = $this->master_model->fetch_all_data_order_by($entity, $selectString, $entity.'_publish_date', 'DESC', $limit, $offset = $page);
$data['all_data']=$all_data;
foreach($all_data as $ad => $row)
{
$fetch = '*';
$table = 'chat';
$cond = $table."_to = 'A' AND post_id = '".$row['post_id']."' AND chat_view_status = 0";
$count = $this->master_model->count_data_by_condition($fetch,$table,$cond);
$pushArr = array('chat_count' => $count);
array_push($row,$pushArr);
}
However, the I can't push the data into the original $all_data.
How can I achieve this?
[0] => Array
(
[post_id] => 37
[post_title] => الأَبْجَدِيَّة العَرَبِيَّة
[post_image] =>
[post_status] => 1
[chant_count] => 2
)
The chat count is retrieved by calling count_data_by_condition() method.

You just need to push the chat_count to correct array. I think your "$all_data" variable is now a part of $data array with key 'data'.
Sample code:
$all_data = $this->master_model->fetch_all_data_order_by($entity, $selectString, $entity.'_publish_date', 'DESC', $limit, $offset = $page);
$data['all_data']=$all_data;
foreach($data['all_data'] as $ad => $row)
{
$fetch = '*';
$table = 'chat';
$cond = $table."_to = 'A' AND post_id = '".$row['post_id']."' AND chat_view_status = 0";
$count = $this->master_model->count_data_by_condition($fetch,$table,$cond);
$data['all_data'][$ad]['chat_count'] = $count;
}
Hope it helps !

Try below code:
$array = array(array("title" => "test", "desc" => "test2"), array("title" => "aaa", "desc" => "bbb"));
echo "before==>";
print_r($array);
foreach ($array as $key => $value) {
$array[$key]["chat_count"] = "123456";
}
echo "<br/>after==>";
print_r($array);

Answer 3

Your array
$arr = array(
0=> array('post_id'=> 7,'post_title'=> 'Title 7'),
1=> array('post_id'=> 8,'post_title'=> 'Title 8'),
);
echo '<pre>';
print_r($arr);
Code snippet
$i=0;
foreach($arr as $eacharr):
$eacharr['chant_count'] = 'Your chat count';
$arr[$i] = $eacharr;
$i++;
endforeach;
echo '<pre>';
print_r($arr);
Output before loop
Array
(
[0] => Array
(
[post_id] => 7
[post_title] => Title 7
)
[1] => Array
(
[post_id] => 8
[post_title] => Title 8
)
)
Output after loop
Array
(
[0] => Array
(
[post_id] => 7
[post_title] => Title 7
[chant_count] => Your chat count
)
[1] => Array
(
[post_id] => 8
[post_title] => Title 8
[chant_count] => Your chat count
)
)

try this example
<?php
$ss = array("0" => Array
(
"post_id" => '37',
"post_title" =>'ss',
"post_image" =>'dsd' ,
"post_status" => '1'
),
"1" => Array
(
"post_id" => '36',
"post_title" => 'TEST open for text',
"post_image" => 'post_1463052793.jpeg',
"post_status" => '1'
),
"2" => Array
(
"post_id" => '35',
"post_title" => 'Hey Sushovan',
"post_image" => 'post_1463038438.jpg',
"post_status" => '1'
)
);
print_r($ss);
$i=1;
foreach($ss as $key=>$row)
{
$ss[$key]['mm']=$i;
$i++;
}
echo "<pre>";
print_r($ss);
?>
OUTPUT
Array
(
[0] => Array
(
[post_id] => 37
[post_title] => ss
[post_image] => dsd
[post_status] => 1
[mm] => 1
)
[1] => Array

[2] => Array
(
[post_id] => 35
[post_title] => Hey Sushovan
[post_image] => post_1463038438.jpg
[post_status] => 1
