数组2

foreach($db as $v){
$v['qian'];

}

循环除以怎么写?>
$v['money']/ $v['qian']
array1 =array([id]=>11 [id]=> 22[id]=> 33[id]=> 44[id]=> 88 [id]=> 99[id]=> 88[id]=> 11[id]=> 22);
array2= array([id]=>11 [id]=> 22[id]=> 33[id]=> 44[id]=> 88 [id]=> 99[id]=> 88[id]=> 11[id]=> 22);

foreach( ??? as $v){
echo $jieguo= (array1=$v['id'] / array2=$v['id'] );
}

Answer 1

<?php
$arr1 = array( 2, 4, 6, 8, 10);
$arr2 = array( 2, 4, 6, 8, 10);

$num = count($arr1);//个数
$arr_new = array(); //空数组，存放相除后的结果
for($i=0; $i<$num; $i++){
$arr_new[] = $arr1[$i]/$arr2[$i];
}

print_r($arr_new);
?>
