get variable value out of a string

pipesportugal · 11-09-2008, 09:11 PM

Hello dear colleagues from the talkphp forum,

I would very much appreciate some help regarding the following subject:

PHP Code:


			
$variable1 = "Hello";

$title = '$variable'."1";

echo $title;

This routine is returning the result:
$variable1

I would like to get the value "Hello" instead.

Can someone explain to me which php function can I use to retrieve the result that I am looking for ?

Thanks in advance,
pipesportugal

No such function needed. The single quotes are printed literally, without printing the contents of a variable, they simply print what you've put. You can either put them all in double quotes, or in no quotes at all:

php Code:

$title = "$variable 1";
$title = $variable . "1";

There are numerous ways of doing this, here are three:

PHP Code:


			
$variable1 = 'Hello';

$title = 'variable1';



echo $$title;

// or

echo ${$title};

// or (assuming global scope)

echo $GLOBALS[$title];

Hello Dear friends Wildhoney and Salathe,

Wildhoney, I think that You did not really understand what I meant, most probably by my faulty description of my needs.

Salathe, the $$ thing has solved it and was what I was looking for. I also understood the GLOBALS solution. That would also do the trick.

Thank You to both of You for disposing of Your time.
