        ) 
    ) 
)

This is my current array. I want to filter only Answer status by phone_num.
Outpout Will Like this:

Phone Num   No of answer  
01755677011 0,23  
01755677012 1  

Can anyone helo me please ??

Answer 1

I do not understand how you get 0,23 for 01755677011. If you are displaying phone_num and the number of times it has "Answer" status, you can do it this way:

$result = array();
foreach ($num as $key => $row) {
    $result[$key] = array();
    $count = 0;
    foreach($row as $key_value => $row_value) {
        if ($row_value['status'] == 'Answer') {
            // $key is the key 01755677011 and 01755677012
            $result[$key]['id'][$count] = $row_value['id'];
            $count++;
        }
    }
}

if (!empty($result)) {
    echo "Phone Num | No of answer<br />";
    foreach ($result as $key => $row) {
        echo $key . " " . count($row['id']) . "<br />";        
    }
}

Second version:

1) Based on "Answer" in either [status] or [2].

2) Display array index of the corresponding phone_num.

$result = array();
foreach ($num as $key => $row) {
    $result[$key] = array();
    $count = 0;
    foreach($row as $key_value => $row_value) {
        if ($row_value['2'] == 'Answer' || $row_value['status'] == 'Answer') {
            // $key is the key 01755677011 and 01755677012
            $result[$key][$count]['index'] = $key_value;
            $count++;
        }
    }
}

print_r($result);

if (!empty($result)) {
    echo "Phone Num | No of answer<br />";
    foreach ($result as $key => $row) {
        echo $key . " | ";
        if (!empty($row)) {
            foreach ($row as $data_key => $data) {
                echo $data['index'];
            }
        } else {
            echo "No record";
        }
        echo "<br />"; 
    }
}
