Accessing variable from a string

[phppup]

I have variables as such

$var0 = "hello";
$var1 = "good bye";
$var2 = "back soon";

I get appropriate results when I do this

echo $var0;  echo $var1;  echo $var2;

Now, I want to get the r same esults using a created string like this

for($x=0; $x <3; $x++){
  $test = "\$var".$x; echo $test."<br>";
  }

But this only provides

$var0
$var1
$var2

How can I generate the respective variable elements so that they reflect their values?

by using an array instead of a series of name-numbered variables.

Put them in an array,

$var = [ "hello", "good bye", "back soon"];
for ($x=0; $x<3; $x++) {
        echo $var[$x] . '<br>';
} 

or

$var0 = "hello";
$var1 = "good bye";
$var2 = "back soon";

test($var0, $var1, $var2);


function test(...$vars)
{
    for ($x=0; $x<3; $x++) {
        echo $vars[$x] . '<br>';
    }
}

I have

function xyz($var0, $var1, $var2)

and I want to see their values visually. I want to generate  FOR-style statement to automate this process.

Did creating a function with elements assigned inadvertently create an array?

What mac_gyver and Barand are trying to tell you is that this idea you have is the wrong way of doing... whatever you want.

As in, don't use multiple arguments named "varX" and instead use a single argument that takes an array.

xyz(1, 2, 3); // no

xyz([1, 2, 3]); // yes
