$a ='1=A # 2=B # 3=C # 4=D';$alist = explode(' # ', $a);foreach($alist as $key=>$value){ $arr=explode('=',$value); $blist[$arr[0]]=$arr[1]; echo "$blist[$key]";}
echo "$blist[$key]"; 只能输出ABC 每次都缺少最后一个 怎么 才能输出 ABCD
回复讨论(解决方案)
直接 echo $arr[1]; 不就行了
一定要用$blist输出的话应该写成 echo "$blist[$key+1]"; 因为你的$blist数组索引是从1开始到4
哦,写错了,应该是 echo $blist[$key+1];
key是0-3
而$arr[0]是1-4
所以不同,改成这样就可以了。
$a ='1=A # 2=B # 3=C # 4=D';$alist = explode(' # ', $a);foreach($alist as $key=>$value){ $arr=explode('=',$value); $blist[$arr[0]-1]=$arr[1]; echo "$blist[$key]";}
$arr[1] 的确能输出 ABCD 可以解决这个问题
那么要输出C 怎么书写? $arr[1[3]] ?貌似不对
key是0-3
而$arr[0]是1-4

也就是 输出单条数据
echo $blist[3]; //C
请注意关联数组和下标数组的区别
