Question

I have this array
Array (
[3] => Array (
[IDFattura] => 3
[Data_Scadenza] => 2011-06-23
[Importo] => 343.30
[IDTipo_Offerta] => A
[Email] => stefano#email.it )
[4] => Array (
[IDFattura] => 4
[Data_Scadenza] => 2011-06-23
[Importo] => 98.40
[IDTipo_Offerta] => A
[Email] => stefano#email.it )
[7] => Array (
[IDFattura] => 33
[Data_Scadenza] => 2011-06-23
[Importo] => 18.40
[IDTipo_Offerta] => A
[Email] => tom#email.it ) )
Now I need send ONE email to each Email, but stefano#email.it (in email body ) will have a table with two rows, instead of Tom that will have 1 row.
Hope you understand me!

Answer 1

try this code
$newarray = array();
foreach($array as $item) $newarray[$item["Email"]] = 1;
$sendarray = array_keys($newarray);
foreach($sendarray as $item) mail(...);
you should also consider array_unique
good luck

Answer 2

You should reformat your array like this:
$newArray = array();
foreach ($yourArray as $key => $value) {
$newArray[$value['Email']][] = $value;
}
It returns array grouped by Email. And for stefano#email.it tou will have an array with 2 items.

Answer 3

Loop through the array and group invoices by email:
$invoicesByEmail = array();
foreach($invoices as $invoice) {
if(!isset($invoicesByEmail[$invoice['Email']])) {
$invoicesByEmail[$invoice['Email']] = array();
}
$invoicesByEmail[$invoice['Email']][] = $invoice;
}
Then, it's a matter of looping through the grouped invoice and mailing them.
foreach($invoicesByEmail as $recipient => $invoices) {
$emailBody = '';
foreach($invoices as $invoice) {
// Parse your invoice
}
Mailer::send($recipient, $emailBody, $headers);
}

Answer 4

Personally, I'd structure the array slightly different. Instead of having numeric keys, i'd set the key as the email address. This way you can simply use array_unique.
If you can't change the array as you get it now, you can loop through it and extract each email address out and insert it into a new array:
$uniqueEmails = array();
foreach ($yourArray as $k => $v) {
if (isset($v['Email']) $uniqueEmails[$v['Email']] = $v['Email'];
}
return $uniqueEmails;
