如何在php中定义数组，如array1 [] array2 []使用for循环[复制]

How to define array in php like array1[] array2[] using for loop like instead of a1 or a2 I can write ai and its in for loop is it possible?

Like

for($i=0;$i<10;$i++)
{
     $ai[$i]="hello'";
}

so I would like to say as like

a1[1]=Hello

</div>

You can access variables dynamically using this:

${"a$i"}[$i] = 'hello';

You could use a dynamic var

 $ai.$i[$i] = 'Hello';

or

 $ai.$i[$your_index] = 'Hello';

but be careful when doing this .. in this case it is difficult to keep in control of the variables .. is easy to make a mistake
