array
(
x=> array(0,01,02,...0x),
y=> array(0,11,12,...1x),
...
n=> array(0,n1,n2,...nx),
)
已知该数组中每个值的长度都是相同的,如:array[x]和array[y]两个数组的长度相等
我想再添加2个键array[a]和array[b],变成
array
(
x=> array(0,01,02,...0x),
y=> array(0,11,12,...1x),
...
n=> array(0,n1,n2,...nx),
a=> array(a,a,a,...b),
b=> array(b,b,b,...b),
)
有什么好的方法吗
(我现在只想到 先获取到所有的keys,然后再获取第1个key的值长度。然后再填充array[a]和array[b])
回复讨论(解决方案)
其实就是想 在array里增加1个键,使这个键的值长度 和其他键的值长度相同
长度相同,那值呢。
值不相同的,只是有相同的键数
array(0,01,02,...0x),
array(0,11,12,...1x),
比如:count 出来都是 10
长度相同,那值呢。
不过新添加进来的这2个数组值是相同的
a=> array(a,a,a,...a),
b=> array(b,b,b,...b),
$ar=你的数组;$c=count($ar['x']);$ar['a']=array_fill(0,$c,"a");print_r($ar);
