PHP推入循环内的数组

Question

I'm generating an array of results within a loop, and I want to add to the array within the loop. Obviously array push will not work as these are key, value pairs.

foreach($res as $ap){
    $this->db->where('event_time >', $ev_time);
    $this->db->where('event_ID', $ap['event_id']);
    $query = $this->db->get('events');
    if($query->num_rows() > 0){
        $result = $query->result_array();
        $linked[] = $result[0]; // <-- want to add key, value pair within this
        $linked['new_key'] = $new_value; // <-- did not work :(
    }
}

How can I do this?

Also this array later gets merged with another array. If I add an extra key, value pair to this that isn't in the other array, will that break the merge?

foreach($res as $ap){
    $this->db->where('event_time >', $ev_time);
    $this->db->where('event_ID', $ap['event_id']);
    $query = $this->db->get('events');
    if($query->num_rows() > 0){
        $result = $query->result_array();
        $linked[] = $result[0]; // <-- want to add key, value pair within this

        $linked['new_key'][] = $new_value;
    }
}

Try this

$i = 0;
foreach($res as $ap){
    $this->db->where('event_time >', $ev_time);
    $this->db->where('event_ID', $ap['event_id']);
    $query = $this->db->get('events');
    if($query->num_rows() > 0){
        $result = $query->result_array();
        $linked[$i] = $result[0]; // <-- want to add key, value pair within this
        $linked[$i]['new_key'] = $new_value;
        $i++;
    }
}

The $i will enable you to add the new value into the same element as the $result[0] was was written to.

也许尝试类似：

$myarray[] = array($key, $value);
