Suppose I have a variable $i =3D 0 or 1 or 2
and I have variables $item0, $item1 and $item2
how do I print the variable $item0 using a combination of variable $item an=
d
variable $i?
or with this code it gives me an error:
$i =3D 0;
$item0 =3D "test";
echo $item$i; #how do I properly use this variable $item with $i?

Thanks in advance, Yours, Grega

$var = "item$i";
echo $$var;

Note the two dollar-signs in the second line.

I wonder if a basic array would make for easier-to-read code, though:

$items = array( "test" );
$i = 0;
echo $items[$i];

Re: variable

Hi Grega

I think you might want to have a look at the array's section of the php
manual.
