Variable Reference

[kwelling]

$tester = 2800;

$mine = 'seven';

 

$x = test;

 

$tst=array(test => $tester,mine => $mine);

 

echo $tst[$x];

 

 

 

Is it possible to make the above php code echo 2800 by changing the reference in the echo statement?  Obviously I could replace $x to test, but I am trying to get what $x references.  Is this even possible in php?

not sure i understand what you mean.

 

do you want to loop through 2800 times?

 

if so:

$i=1;
while ($i<=2800){
echo $i;
$i++;
}

 

with regard to the thing in your post... you might want to change the array to $tst=array($x=>$tester, .........

 

other than that... i don't get it.

Im pretty sure what you are after are variable variables:

 

<?php
$foo = 1;
$bar = 2;
$var = 'foo';
echo $$var; //echos 1;
$var = 'bar';
echo $$var; //echos 2;
?>

<?php

 $tester = 2800;
 $mine = 'seven';

 $x = 'test';

 $tst=array($$test => $tester,${'mine'} => $mine);

 echo $tst[$x];

?>
