$ArrayKeys=array_keys($data);
$cntKeys=count($ArrayKeys);
for ($i=0;$i<$cntKeys;$i++)
{
$data[$ArrayKeys[$i]]["image"]="ciro";
}
print_r ($data);
Let's suppose that your array is called "data".
In this way you get can the keys of your array (0,1,2....) and on each of them you iterate to access to the img value...
Then you can access to the value using $data[key_your_array]["image"] = "something". I use
$data[$ArrayKeys[$i]]
because, as the name suggest, $ArrayKeys is an array and I want to access to the i-th element
