[php] sumowanie tablic Opcje

[AndyPSV]

Otrzymuje cos takiego, chce to "zsumowac" (pole "cnt"), aby liczylo sie prawidlowo, czyli dodawalo;

jest to wynik dzialania kodu
$pm = array_merge($pm1,$pm2);

array (
0 =>
array (
'id' => '3',
'id_' => '21',
'_from' => '42',
'_from_t' => '',
'_to' => '1',
't' => 'Fabulous',
'date' => '2011-02-27 22:47:54',
'msg' => 'nnnn',
'read' => '1',
'cnt' => '1',
),
1 =>
array (
'id' => '1',
'id_' => '20',
'_from' => '42',
'_from_t' => '',
'_to' => '1',
't' => 'Convenience',
'date' => '2011-02-27 22:46:04',
'msg' => 'dd',
'read' => '1',
'cnt' => '2',
),
2 =>
array (
'id' => '4',
'id_' => '21',
'_from' => '42',
'_from_t' => '',
'_to' => '1',
't' => 'Fabulous',
'date' => '2011-02-27 22:48:24',
'msg' => 'no czesc co tam',
'read' => '1',
'cnt' => '2',
'_temp' => '42',
),
)
