json数据格式拼凑，数组合并，求助！
有三个数组
$arr = array('张三','李四','王五');
$arr2 = array(100,200,300);
$arr3 = array(50,60,70);
如何平凑成另外一个数组$array，最后echo json_encode($array)输出如下格式
{total:3,
result:[
{date:1,name:张三,value:100,other:50},
{date:1,name:李四,value:200,other:60},
{date:1,name:王五,value:300,other:70}
]
}
兄弟们，help…
------解决方案--------------------
$date,name=>$arr[$i],value=>$arr2[$i],other=>$arr3[$i]);
}
echo json_encode($result);
/*
{total:3,
result:[
{date:1,name:张三,value:100,other:50},
{date:1,name:李四,value:200,other:60},
{date:1,name:王五,value:300,other:70}
]
}
