Hy,
i had a problem which was associated with the array_count_values function, but did not solve my
problem realy well so i made a function by my self and maybe it can help also someone else.
The problem was that i had a table like this:
CL PRODNUM QN DATE
1 4221110030 2 10.12.2010
2 4221110031 1 10.12.2010
3 5241110002 1 10.12.2010
3 5241110003 1 11.12.2010
3 5241110001 2 11.12.2010
3 6241110001 1 11.12.2010
1 2231110999 1 10.12.2010
1 2231110999 1 11.12.2010
(it go's on and on ... )
And i wanted to calculate for every unique date how much the quantity of the specific CL is.
For example the result should be like this:
10.12.2010: [1] -> 3
10.12.2010: [2] -> 1
10.12.2010: [3] -> 1
11.12.2010: [1] -> 1
11.12.2010: [2] -> 0
11.12.2010: [3] -> 4
So, i had to make a function which should look for unique values of a date and then for that date
get the quantity of uniqe CL's.
For note: i put all the values of the table into an array:
<?php
$a = array();
$a['cl'] = 1;
$a['prodnum'] = '4221110030';
$a['qn'] = '2';
$a['date'] = '10.12.2010';
?>
The function looks like this:
<?php
function csav( $array, $distinctV, $searchInV, $sumValue ){
#result array
$result = array();
#finding the unique dates
$array1 = array_unique($array[$searchInV]);
$array2 = array();
$unique1 = array_merge($array2, $array1);
#finding the unique CL's
$array3 = array_unique($array[$distinctV]);
$array4 = array();
$unique2 = array_merge($array4, $array3);
#for statements through the unique dates
for($k = 0; $k < count($unique1); $k++){
for($i = 0; $i < count($unique2); $i++){
$sum = 0;
for($j = 0; $j < count($array[$distinctV]); $j++){
if($array[$distinctV][$j] == $unique2[$i] and $array[$searchInV][$j] == $unique1[$k])
$sum += $array[$sumValue][$j];
}
$result[$unique1[$k]][$unique2[$i]] = $sum;
}
}
return $result;
}
?>
The use of function has to be like this:
<?php
$result = csav($a, 'cl', 'date', 'qn');
print_r($result);
?>
And the result looks like this:
Array ( [2010-12-10] => Array ( [1] => 14 [2] => 17 [3] => 4 ) [2010-12-13] => Array
( [1] => 13 [2] => 17 [3] => 4 ) [2010-12-14] => Array ( [1] => 13 [2] => 17 [3]
=> 4 ) [2010-12-15] => Array ( [1] => 14 [2] => 17 [3] => 4 ) [2010-12-16] =>
Array ( [1] => 14 [2] => 17 [3] => 2 ) )
This is it.
Hope it helps someone.
