Re: [PHP] Making varibles (more than one) with a function.

David:

 makevars() {
 list($md5,$pusername,$pproject,$pfile) = explode(:,$authok);
 $user = $pusername;
 $project = $pproject;
 $file = $pfile;
 }

Uh, why are you wasting memory and time by reassigning the variables?  
Why not call the variables what you want them to be in the first place?

   makevars() {
  list($md5, $user, $project, $file) = explode(':', $authok);
   }


 How could I have a function create variables that can be used in other
 functions?

A few options.

1)  Assign them to some other array and then declare that array global in the 
creatingn and receiving functions.

   makevars() {
  global $Vars;
  list($Vars['md5'], $Vars['user'], $Vars['project'], $Vars['file'])
  = explode(':', $authok);
   }

   function other() {
  global  $Vars;
  echo $Vars['md5'];
   }

2)  Assign the stuff to the $GLOBALS[] array.

   function makevars() {
  list($GLOBALS['md5'], $GLOBALS['user'], $GLOBALS['project'],
  $GLOBALS['file']) = explode(:,$authok);
   }

   function other() {
  echo $GLOBALS['md5'];
   }
   
3)  Declare each variable global in the creatingn and receiving functions.

   makevars() {
  global $md5, $user, $project, $file;
  list($md5, $user, $project, $file) = explode(':', $authok);
   }

   makevars() {
  global $md5, $user, $project, $file;
  echo $md5;
   }


Enjoy,

  I am aware that return can return strings but is their a set global or a
  function similar to return?

 hi there!,
 There sure is, it's called global.
 Usage:
 global $variable_a;
 global $variable_b;
 global $variable_c;
 ...

 HTH,

2002-05-23 Thread Steve Edberg 

Because global is specific to the SCOPE not to the variable - 
variables themselves aren't tagged as global. If you add

global $text;

in your echoo() function it will work. Alternatively, you could replace

echo $text;
with
echo $GLOBALS['text'];

in your echoo() function.

See
http://www.php.net/manual/en/language.variables.php

for more info.
