I have these arrays:
Array ([265] => 9.00)
Array ([265] => 9.00)
Array ([265] => 9.00)
Array ([265] => 9.00)
Array ([326] => 20.00)
I want to count the amount of reptitions and their corresponding sum:
265 repeated 4 times and the sum of it's value is 36
326 repeated 1 time and the sum of it's value is 20
I would appreciate your help.
Thanks
$total = array();
foreach($arrays as $array) {
foreach($array as $key => $value) {
if (!isset($total[$key])) {
$total[$key]['hits'] = 0;
$total[$key]['count'] = 0;
}
$total[$key]['hits']++;
$total[$key]['count']+= $value;
}
}
Check out my code, Function: http://phpfiddle.org/main/code/7ia-40m
$a = array ( array( 265 => '9.00'), array(265 => '9.00'), array(326 => '20.00') );
echo '<pre>'; print_r(getDetails($a)); echo '</pre>';
function getDetails($array) {
$a = $array;
$b = array();
foreach($a as $ar) {
$n=0;
foreach($ar as $k => $v) {
$n++;
if(isset($b[$k])) {
$b[$k]['val'] = ($b[$k]['val'] + $v);
$b[$k]['total']++;
} else {
$b[$k]['val'] = (0 + $v);
$b[$k]['total'] = (1);
}
}
}
$string = '';
foreach($b as $k => $arr) {
$val = $arr['val']; $key = $k; $tot = $arr['total'];
$string .= $key.' repeated '.$tot.' times. Sum : '.$val.' <br />';
}
return $string;
}
Result:
265 repeated 2 times. Sum : 18
326 repeated 1 times. Sum : 20
Check This
<?php
$arr=array(
array('265'=>'5'),
array('265'=>'5'),
array('265'=>'1'),
array('280'=>'3')
);
$sets = array();
foreach($arr as $array)
{
foreach($array as $arrayset=>$cent)
{
$sets[$arrayset][] = $cent;
if(isset($abc[$arrayset])) // prevent index warning
{
$abc[$arrayset] += $cent;
}
else
{
$abc[$arrayset] = $cent;
}
}
}
echo "<pre>";
print_r($abc);
?>
Output
Array
(
[265] => 11
[280] => 3
)
array_merge_recursive&array_sum, what code can you come up with?
