Is it possible to do something like this?

[doogles]

It was hard to explain with just the title, so I figured I'll explain what I mean here:

 

Say I have various variables with the same name and different endings, like $test1, $test2, $test3, $test4, etc...

 

Would it be possible to create a loop that will do something to each of those variables instead of me typing it for each and every one?

 

Something like:

 

for($x=1; $x <=4; $x++) {echo $test$x;} so it would print each test variable, 1-4? Obviously combining the two variables is impossible. Do I need to encase the $x in something like $test".$x." ?

 

Thanks !

Not sure but if you can get away with using an array that might be your best option then set up a loop like this:

foreach ($myarray as $var) {
  echo $var;
}

so,

 

$test_array=array("$test1","$test2","$test3","$test4");

foreach($test_array as $var) {echo $var;}

In array() don't enclose the variables in quotes.

alright, thanks

Try this:

<?php
$test1 = 'one';
$test2 = 'two';
$test3 = 'three';
$test4 = 'four';

for ($i = 1; $i < 5; $i++) {
  echo $test{$i} . '<br />';
}
?>

I've just learnt something new...

A few different ways obviously.

 

<?php

  for ($x=1; $x <=4; $x++) {
    $var = 'test'.$x;
    echo $$var;
  }

?>

Actually, I don't think Obsidians way will work. Though I haven't tested, I think you would need something more like....

 

<?php

  $test1 = 'one';
  $test2 = 'two';
  $test3 = 'three';
  $test4 = 'four';

  for ($x=1; $x <=4; $x++) {
    echo ${'test'.$x};
  }  

?>

Thorpe, you're exactly right. My bad. That's what I was intending... it's just way to late tonight.

 

Sorry, guys. Thanks, Thorpe.
