Is there anyway to do this?

[l0ve2hat3]

<?
$josh1="it worked";
$i=0;
while($i < 3){
    $i++;
    echo $josh$i;

}
?>

i want to echo $josh1 via loop

You can use variable variables. I'll let you look up in the manual how, because they are not the best way of using sets of related data.

 

Any time you have a set (two or more) of related data, use an array instead of sequentially named variables. Using variable variables are 3 times slower than an array and the code necessary to set create, keep track of how many of them there are, and access them is more complicated than if you just use an array.

You can't create a variable or use it's value in the manner in which you have tried to do. I recommend using an array:

 

<?php
$josh1[] = "it worked";
for($i=0;$i<=3;$i++){
     if(isset($jost1["$i"])){
          echo $josh1["$i"];
     }
}
?>

i know how to use arrays, im modding existing code. not fun. unfortuantly it would mean major rewrites to use arrays. so i cant even use variable variables?

 

[sKunKbad]

nope... variable variables don't exist in php

Probably reading this will help - http://www.php.net/manual/en/language.variables.variable.php

 

Variable variables do exist. Please don't post information unless you have first hand knowledge of what you are posting.

[l0ve2hat3]

yeah i read that but it doesnt seem to work in my case

[PFMaBiSmAd]

You would need to post your code to get help with what it is doing.

[l0ve2hat3]

well i have. but i will agian

<?
$josh1="it worked";
$i=0;
while($i < 3){
    $i++;
    echo $josh$i;

}
?>

[l0ve2hat3]

what the manual explians doesnt seem like it works for what i want it to do.  can you please give me a simple example that would work in my case?

[PFMaBiSmAd]

Tested -

 

<?php
$josh1="it worked 1";
$josh2="it worked 2";
$i = 1;
while($i < 3){
echo ${"josh$i"};
echo "<br />";
    $i++;
}
?>

My first hand experience with variable variables was that I was in here a while back trying to use them and it was said that it couldn't be done...

thank you. works perfect

Variable variables :

 

<?php
$josh1 = "it worked 1" ;
$josh2 = "it worked 2" ;
$i = 1;
while($i < 3){
           $this = "josh" . $i ;
           echo $$this ;
           echo "<br />" ;
           $i++;
}
?>

Your code is functionally equivalent to the code previously posted, except it adds an unnecessary intermediate variable and an unnecessary line of code to set that unnecessary variable, making it even slower.
