for example
$array1 = array(item1=>5,item2=>7);
$array2 = array(item1=>5,item3=>7);
Actually i want to first check the array, if same key exist means value should be (arithmetically) added otherwise if not exists then it directly pushed to the array.
my output will be like
$nov-2014 =array(item1=>10,item2=>7,item3=>7)
You can just plainly use a simple for and a foreach for that purpose. Of course create the final container. Initialize values, then just continually add thru keys:
$array1 = array('item1'=>5,'item2'=>7);
$array2 = array('item1'=>5,'item3'=>7);
$result = array();
for($x = 1; $x <= 2; $x++) {
foreach(${"array$x"} as $key => $values) {
if(!isset($result[$key])) $result[$key] = 0; // initialize
$result[$key] += $values; // add
}
}
print_r($result);
${"array$x"}
$array1 and $array2, oh i wish those arrays weren't separate, it could have been much easier, but anyway, i'l just have to work on what the OP got above thereTry this:
$array1 = array(
'item1' => 5,
'item2' => 7
);
$array2 = array(
'item1' => 5,
'item3' => 7
);
$array_new = $array2;
foreach ($array1 as $key => $value) {
if (!in_array($key, $array2)) {
$array_new[$key] = $value + $array2[$key];
}
}
I think there is no built PHP function, use foreach.
$array1 = array('item1' => 5, 'item2' => 7);
$array2 = array('item1' => 5, 'item3' => 7);
$result = $array1;
foreach ($array2 as $key => $val) {
if (isset($result[$key])) {
$result[$key] += $val;
} else {
$result[$key] = $val;
}
}
/*
Output:
Array
(
[item1] => 10
[item2] => 7
[item3] => 7
)
*/
