Variable Variables in PHPi-1
Every so often when you are writing a php file, we all run into a situation where we would like for the name of the
string that is inside of your php variable to be converted into the actual name of another variable.
After a fair amount of hunting around the internet and getting sent off into PHP code hunting limbo for a few hours, I suddenly remembered that this was something that I had found a solution to some time ago. Now, had I been prudent about my little discovery, I would have put it up here on mrarrowhead.com. Instead I forgot about it until I accidentally ran across variable variables agains in the php manual. Variable variables was exactly what I was looking for to get a string from one variable and change it to the name of another variable in my php scipt.
So here goes:
$var = varIwannaMake;
$$var = Im in varIwannaMake;
echo $$var. //<--- this will output the above sentence;
echo $varIwannaMake; // this will output the same thing
The scirpt above will output the following:
Im in varIwannaMake
Im in varIwannaMake
Short and sweet - simple to use -- hope you like.
