I have two arrays
$data1 = array()
$data1 = array( '10','22','30')
and also another array carries
$data2 = array()
$data2 = array( '2','11','3');
I need to divide these two arrays(ie,$data1/$data2) and store value to $data3[]. I need to get it as follows
$data3[] = array('5','2','10')
If someone knows of an easy way to do this would be of great help. Thanks
You can do that with a simple foreach statement:
$data1 = array('10','22','30')
$data2 = array('2','11','3');
$data3 = array();
foreach($data1 as $key => $value) {
$data3[$key] = $value / $data2[$key];
}
Alternatively you can use array_map:
function divide($a, $b) {
return $a / $b;
}
$data3 = array_map("divide", $data1, $data2);
And as of PHP 5.3 you can even use a lambda function to compress that to one row:
$data3 = array_map(function($a, $b) { return $a / $b; }, $data1, $data2);
