String as part of a variable name

[matt72]

This has been bugging me for a while now! I'm trying to figure out a way to make a string part of a variable name. I know you can do this:

$var = 'string';
$$var = 'something';
echo $string;

however, I'd like to concatenate the term 'string' with something else, such as:

$var = 'string';
$$var._test = 'something';
echo $string_test;

That syntax isn't correct, but I'm wondering if there is some way to do it?

Cheers

You can append literals using {} around the literal.

Thanks for your reply! I tried using {}'s in pretty much every position possible, but it didn't help. Could you please give me an example?

A few examples, last one confused me a bit 🙂

$foo = 'foo';
$$foo = 'foobar';
echo $foo; // foobar

$foo = 'foo';
${$foo.'bar'} = 'foobar';
echo $foobar; // foobar

$foo = 'foo';
echo $$foo{'bar'} = 'bar';
echo $f; // barbar - wierd :)

This page explains many things.

Cheers Shrike, that's exactly what I needed! 🙂
