Subject: [PHP] Parsing variables within string variables
I've been bashing my head against the wall on this, and would be glad of
help to stop.
I have a variable containing a string that contains the names of
variables, and want to output the variable with the variables it
contains evaluated. E.g.
$foo contains 'cat'
$bar contains 'Hello $foo'
and I want to output $bar as
Hello cat
The problem is that if I use
echo $bar
I just get
Hello $foo
Note that $bar is loaded from a database query, so I can't control its
contents: I just have to parse it.
Any help appreciated.
David.
