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.

David, You need to EVALUATE the string coming from the database: Assuming that $sDataField contains the string 'Hello $foo':

        $foo = "cat";
        $sText = eval($sDataField);

RESULT: $sText = "Hello cat" http://php.net/eval Paul
