searching in multidimensional array for a date

Hello to everybody, I am using the following function in order to search in multi-dimensional array, as per note added on http://it.php.net/array_search, [code] function array_search_recursive($data0, $FinRecSet, $a=0, $nodes_temp=array()){ global $nodes_found; $a++; foreach ($FinRecSet as $key1=>$value1) { $nodes_temp[$a] = $key1; if (is_array($value1)){ array_search_recursive($data0, $value1, $a, $nodes_temp); } else if ($value1 === $data0){ $nodes_found = $nodes_temp[1]; } } return $nodes_found; } [/code] where $data0 is a date (ex:'1-1-2008') and $FinRecSet is an array containing financial entries like this Array ( => Array ( [Id] => 281 [Date] => 01-01-2008 [FCode] => A01 [Descr] => Prova [Debit] => 100.00 [RunDeb] => 2065300.64 [Credit] => 0..00 [RunCre] => 3020765.67 [RunBal] => -955465.03 [Rec] => 0 ) [1] => Array ( [Id] => 282 [Date] => 01-01-2008 [FCode] => A02 [Descr] => Prova [Debit] => 120.00 [RunDeb] => 2065420.64 [Credit] => 0..00 [RunCre] => 3020765.67 [RunBal] => -955345.03 [Rec] => 0 ) ect..... when I run function I get exactely the last entry with date = '1-1-2008', problem is when I don't have entries on such date, for that I should modify function in order to get entry on older date available before $data0. For example if $date0 = '1-1-2008' and first entry is available only on '30-12-2007', how should I modify function? Thank you for your attention. Amos
