Store value in multi-dimentional array on unique key - php

Question

How do I display the following using the array shown below?
Pastors
key=>0, member_id, member_name
Deacons
key=>1, member_id, member_name
key=>2, member_id, member_name
Here is the array.
array (size=3)
0 =>
array (size=4)
'category_name' => string 'Pastors' (length=7)
'member_id' => string '3' (length=1)
'member_name' => string 'Tiny Marshall' (length=13)
'member_email' => string 'jconley#nowhere.com' (length=19)
1 =>
array (size=4)
'category_name' => string 'Deacons' (length=7)
'member_id' => string '1' (length=1)
'member_name' => string 'Jeremiah Conley' (length=15)
'member_email' => string 'jconley#nowhere.com' (length=19)
2 =>
array (size=4)
'category_name' => string 'Deacons' (length=7)
'member_id' => string '2' (length=1)
'member_name' => string 'Marcy Conley' (length=12)
'member_email' => string 'jconley#nowhere.com' (length=19)
Here is the code that I used to build the array:
while( $row = mysql_fetch_assoc( $result ) )
{
$staff[$i] = array
(
'category_name' => $row['category_name'],
'member_id' => $row['member_id'],
'member_name' => $row['member_name'],
'member_email' => $row['member_email'],
);
$i++;
}
This is the final solution:
$category_name = array();
foreach ($staff as $member) {
if (!in_array( $member['category_name'], $category_name ))
{
echo '<h1>' . $member['category_name'] . '</h1>';
$category_name[] = $member['category_name'];
}
echo $member['member_id'] . ', ' . $member['member_name'] . '<br />';
}

Use foreach to loop over your $staff array.
$pastors = array();
$deacons = array();
foreach ($staff as $member) {
if ($member['category_name'] == 'Pastors') {
$pastors[] = $member['member_id'] . ', ' . $member['member_name'];
} else if ($member['category_name'] == 'Deacons') {
$deacons[] = $member['member_id'] . ', ' . $member['member_name'];
}
}
