PHP Variable name add 1

Question

I use a loop and 8 variables with almost the same name.

$date1,$date2,$date3,etc..

Now I want to do in the loop echo $date$i Any idea how to achieve this ?

The PHP loop :

$i = 1;
while ($i < 8 ) {
echo $date$i;
$i++;
}

If you need to number your variables, then you'd be better using an array — Mark Baker, May 04 '15 at 11:35
If yoy really need to use this structure, then use [Variable variables](http://www.php.net/manual/en/language.variables.variable.php) — Mark Baker, May 04 '15 at 11:35
or use the [eval function](http://php.net/manual/en/function.eval.php) — Peter Schneider, May 04 '15 at 11:36

Usually you'll use an array for that:

$data = array('x', 'y', 'z', 'a', 'b', 'c', '1' , '2');
for($i = 0; $i < 8; $i++) {
    echo $data[$i];
}

However if you for whatever reason need 8 variables (I can't see a reason), you need to do it like this:

for($i = 0; $i < 8; $i++) {
    echo ${"data$i"};
}

As mentioned by others before, a better way to go about this this would be to use arrays. Anyways correct syntax for what you want to do would be

$i = 1;
while ($i < 8 ) {
echo ${"date$i"};
$i++;
}
