Question

如果我想在 PHP 中具有相同索引的数组中添加多个值，那么是否可以创建这种类型的数组？例如，

fruits[a]="apple";
fruits[a]="banana";
fruits[a]="cherry";
fruits[b]="pineapple";
fruits[b]="grappes";

我希望数组如下所示： -

fruits = {[a]=>"apple",[a]=>"banana",[a]=>"cherry",[b]=>"pineapple",[b]=>"grappes"};

Answer 1

您无法在相同的键或索引下定义多个值。在你的情况下 -

fruits[a]="apple";
fruits[a]="banana";

此处apple将替换为banana。

相反，您可以将数组定义为 -

fruits[a][] = "apple";
fruits[a][] = "banana";

Answer 2

编辑：我用PHP代码更新了我的答案，但我通常不编码php，这可能不是最优的解决方案，我在php沙箱中尝试了这段代码

$subarray1[0] = "apple";
$subarray1[1] = "banana";
$subarray1[2] = "cherry";

$subarray2[0] = "pineapple";
$subarray2[1] = "grappes";

$fruits[0] = $subarray1;
$fruits[1] = $subarray2;

foreach( $fruits as $key => $value ){
    foreach( $value as $key2 => $value2 ){
        echo $key2."\t=>\t".$value2."\n";
    }
}

Answer 3

使用内爆并爆炸。

subarray1[0] = "apple"
subarray1[1] = "banana"
subarray1[2] = "cherry"

subarray2[0] = "pineapple"
subarray2[1] = "grappes"

商店数据是，（逗号）

$ar="";
for($i=0;$i<=count(subarray1);$i++)
{
$ar[]=subarray1[$i];
}
$rt=implode(',',$ar);
 echo $rt;

删除，（逗号）表格数组

$ex=explode(",",$ar);
print_r($ex);

使用相同索引在同一数组中存储多个值
