string(1) "2"
}
["buy_number"]=>

这种数组 我怎么循环能得到 【0】对应的一组数据，【1】对应的一组数据

Answer 1

 <?php
$arr_person=array(
"goods_id"=>
array( 
0=> "1",
1=> "2"
),
"buy_number"=>
array(
0=> "22",
1=>"22"
),
"buy_price"=>
array(
0=> "20.00",
1=> "20.00"
)
);

foreach($arr_person as $key=>$val) {
     foreach($val as $key1=>$val1) {
         print "<br>".$key1."=>".$val1;
     }
}
?>
