[Resolved] variable variables

[helz]

everytime i need to use them i always get myself confused 🙂
heres what i want to do:
create a variable with the name:
caption_$i where $i is part of a loop
so the variables created will be:
$caption_1
$caption_2
$caption_3

The easiest way is to create a variable with the name in it ( can't get confused )

$ii = "caption_$i";
$$ii = "caption text";

[helz]

ah wicked
so i got this now:

$cap = "caption_$counter";
$$cap = $caption;//new variable made, called: $caption_1 etc

now later on in the script ive got another loop where i want to output the different variables values.
would this work:

for($i=1;$i==3;$i++) {
   $newcap = "cap_$i";
   echo $$newcap;
}

[HalfaBee]

Yep.
for( $i=1;$i<=3;$i++ )

[helz]

turned out that i needed to do:
echo "blah blah ${$newcap} blah de blah";

[HalfaBee]

This is a complex variable.
You need to use the braces for variable variables and arrays ect. in strings.
You could always do this

echo 'blah ' . $$blah . ' more blah';

aye.
thanks for that
