0 => array(
'key1' = value
'key2' = value
}
1 => array(
'key1' = value
'key2' = value
}
Is there a fast way of getting the sum of id=>key1 and id2=key1 so that I don't have to loop through?
I'd like it to see the array as
array(
0 = value (key1)
1 = value (key1)
)
But if it isn't built in somehow, it probably would be another step.
Using PHP 5.5's array_column() function
$result = array_sum(
array_column(
$myArray,
'key1'
)
);
for PHP < 5.5
$result = array_sum(
array_map(
$myArray,
function ($value) { return $value['key1']; }
)
);
