Question

我有两个阵列。

$data1 = array()
$data1 = array(  10 , 22 , 30 )

其他阵列

$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

各位可以作简单的发言:

$data1 = array( 10 , 22 , 30 )
$data2 = array( 2 , 11 , 3 );
$data3 = array();

foreach($data1 as $key => $value) {
    $data3[$key] = $value / $data2[$key];
}

也可以使用array_map:

function divide($a, $b) {
    return $a / $b;
}

$data3 = array_map("divide", $data1, $data2);

而到PHP5.3为止,你甚至可以使用斜杆功能压缩到一行:

$data3 = array_map(function($a, $b) { return $a / $b; }, $data1, $data2);
