how to work on modified elements of an array in php - php

Question

This is my code,
foreach ( $tick_data as $tick_index => $tick_entries ) {
foreach ( $base_data as $baseproject ) {
if ( $baseproject['name'] == $tick_entries['project_name'] )
$projects_id_tickcamp[$baseproject['id']]['tick_id'] = $tick_entries['project_id'];
}
}
which gives multidimensional array:
Array
(
[1181543] => Array
(
[tick_id] => 445196
)
[1287834] => Array
(
[tick_id] => 437574
)
)
and in this code, after apply post message function, i am getting different array named message id created an sub array:
foreach ( $projects_id_tickcamp as $basecamp_project_id => $tick_id ) {
$post_message_id = $this->post_message( $basecamp_project_id );
$projects_id_tickcamp[$basecamp_project_id]['message_id'] = $post_message_id;
}
Output of this code:
Array
(
[1181543] => Array
(
[tick_id] => 445196
[message_id] => 5208908
)
[1287834] => Array
(
[tick_id] => 437574
[message_id] => 5208912
)
)
Problem is if i am getting more $baseproject['id'] in future then i have to post message on that $baseproject['id'] except on the whole array again. Please have a look on this question, any suggestion would be grateful to me.
