Foreach loop with array to match only certain values

[sohost]

Hello. Sorry if this has been addressed before, but I did search and try figure this out. My last resort is always opening a new thread....

I have the following multidimensional array :

Array
(
    [0] => Array
        (
            [id] => 1
            [fullname] => Test Contact 1
            [email] => [e-mail]
            [type] => Technical Contact
        )

[1] => Array
    (
        [id] => 24
        [fullname] => Test Contact 2
        [email] => [e-mail]
        [type] => Technical Contact
    )

[2] => Array
    (
        [id] => 25
        [fullname] => Test Contact 3
        [email] => [e-mail]
        [type] => Billing Contact
    )

[3] => Array
    (
        [id] => 29
        [fullname] => Test Contact 4
        [email] => [e-mail]
        [type] => Billing Contact
    )

[4] => Array
    (
        [id] => 37
        [fullname] => Test Contact 5
        [email] => [e-mail]
        [type] => Billing Contact
    )

)

What I want to do is get each of the same [type] of contact into a single variable so I can echo the variable.

In other words, for each of the [type] => Billing Contact above (there are 3), and each of the [type] => Technical Contact above (there are 2) I want to concatenate all the other values into a single variable like this:

$billing_contact
$technical_contact

I then want to be able to simply echo this variable:

echo $billing_contact;

Which I then want to show some html like this

Test Contact 3<br />
[e-mail]<br /><br />
Test Contact 4<br />
[e-mail]<br /><br />
Test Contact 5<br />
[e-mail]<br /><br />

So the output to the screen looks like this:

Test Contact 3
[e-mail]

Test Contact 4
[e-mail]

Test Contact 5
[e-mail]

I've been trying all sorts of foreach loops and concatenate to try get things into the single variable format I need, but i'm stuck...

I have to get the full set of results for all the same [type] values into a single variable because I use str_replace when rendering the output.

The system is using a homegrown template type system, which means I look for {$billing_contacts} in PHP and simply replace {$billing_contacts} with $billing_contacts

I then echo $billing_contacts and want to get the list as mentioned.

I hope I have not confused anyone, but please try give me a hand since this is driving me nuts!

Thank you in advance for your time and help.

The first thing to do would be to build an array with all the records grouped indexed by [type]; then each [type] can be dealt with independently of the others.

$records_by_type = array();
foreach($records as $record)
{
    $records_by_type[$record['type']][] = $record;
}
