代码
$two[0][0]=100;
$two[1][0]=110;
$two[2][0]=120;
var_dump($two);
echo "<br> two[0][0]=$two[0][0]";
echo "<br> two[1][0]=$two[1].0";
echo "<br> two[2][0]=$two[2]";
输出
array (size=3)
0 =>
array (size=1)
0 => int 100
1 =>
array (size=1)
0 => int 110
2 =>
array (size=1)
0 => int 120
( ! ) Notice: Array to string conversion
two[0][0]=Array[0]
two[1][0]=Array.0
two[2][0]=Array
如何从这个二维数组中获取值?我可以使用echo $single[1]
答案 0 :(得分:1)
使用echo "<br> two[0][0]=$two[0][0]";
它读为$two[0]. "[0]"
,返回输出为Array[0]
尝试
echo "<br> two[0][0]=" . $two[0][0];
或
echo "<br> two[0][0]={$two[0][0]}";
将您的代码更改为
$two[0][0]=100;
$two[1][0]=110;
$two[2][0]=120;
var_dump($two);
echo "<br> two[0][0]={$two[0][0]}";
echo "<br> two[1][0]={$two[1][0]}";
echo "<br> two[2][0]={$two[2][0]}";

尝试改变这种方式,
$two[0][0]=100;
$two[1][0]=110;
$two[2][0]=120;
echo "<pre>";
print_r($two);
echo "</pre>";
echo "\n";
//concatenate your 2d array with string here
echo "two[0][0]=".$two[0][0]."\n";
echo "two[1][0]=".$two[1][0]."\n";
echo "two[2][0]=".$two[2][0]."\n";
