Re: [PHP] extract() question

[Jason G.]

I needed this once, but I could not figure out how to just create the vars 
in current scope.

If my_extract() is called from within a function, then the variables will 
not be available unless you declare them global (which kinda makes the 
function pointless).

Any ideas?

You may want to do something like this instead:

[PHP] extract() question

[David Bernier]

There is this array which I would like to convert into a series variables using the 
extract function: 

 "courage", 
 "dorothy" => "kansas", 
 "scarecrow" => "brain"
 "tin man" => "heart"); 

extract($oz);
?>

now, I would like to access my new variables. it is obviously easy for $lion, 
$dorothy, and $scarecrow but it isn't for "tin man".

from this, I have 3 or 4 questions:
1) has $oz["tin man"] been passed into a variable?
2) if yes, how do I access the variable that came out of $oz["tin man"]?
3) let's pretend that I have no control over the names of the keys for $oz, how should 
I have called extract() to tell it to replace the space between "tin" and "man" by a 
underscore character?
4)  finally, is there a way to access and retrieve that values of the symbol table 
without knowing their names?
