echo the variable of a value of a variable.

[dammyg]

Hi, probably very simple but just wondering how to echo out something like below:

eg: $variable="echothisvariable";

//i want to echo $echothisvariable

 

Thank You

$variable="echothisvariable";
echo $variable;

Hi, I am trying to echo like this:

 

echo $(echo $variable;);

 

Thank You

it's terrible practice and you should use arrays, but you CAN technically do

 

echo $$variable;

 

but I wouldn't advise it.

[ratcateme]

what about

$variable="echothisvariable";
$echothisvariable = "this is to be echoed";
echo $$variable;

then it would echo

"this is to be echoed"

 

nothing special

Are you trying to do this:

 

<?php
$variable="echothisvariable";
${$variable} = "this is to be echoed";
echo ${$variable};
?>

 

That would set and echo the variable $echothisvariable.

Or do you want it like this?

 

$echo = '$variable="echothisvariable"';
echo $echo;

 

???

I feel like we're playing charades!

 

Um... two words, first word ECHO!
