At first i would rather use the LIMIT from MySQL than a for loop.

$query = SELECT * FROM foo WHERE bar = 'foobar' LIMIT 5;
$result = mysql_query($query);
// Now you can use a while loop to print it out
while ($row = mysql_fetch_assoc($result))
// mysql_fetch_assoc is the same as mysql_fetch_array with ASSOC
  {
echo $row[somefield];
// to have it availible out of the code use this
$outer_array[] = $row;
  }
print_r($outer_array);

// now the array has the fields of the Query in it.
// as you can see using print_r();

// now you can access it like:
$outer_array[0];
$outer_array[1];
...
$outer_array[n];


Your FOR loop replaces the variable $result everytime.
That's why it is empty.

 When registered globals is set to off this does not effect the $PHP_SELF
 variable right?  In other words I should be able to call $PHP_SELF with
 out having to do this $_SERVER['PHP_SELF'], right?

 Thanks,
 Jason Giangrande

I would assume that if you turned register_globals off $PHP_SELF will no
longer be available.  Course you can always extract($_SERVER); if you want
the effect of register_globals inside your script without turning the
feature on globally.

Maybe you could use sessions like:
session_start();
session_register('verified');
$verified=0

 I have developed a simple login script.  Right now it will check a
submitted
 username and password and verify it against a database.  This part works
 fairly well, however I want to know how to assign a variable that will
pass
 through to the next page(s) to do something like:

 if verified == 1 then {display the page} else {display error message}

 My apoligies on the syntax of the above, but hopefully you will get the
 idea.

 Hi folks,
 
 small problem with globals:
 
 I would like to set a variable global called Language
 
 This seems to be not a really problem, but it is
 
 Indexphp:
 
 ?php {
   session_start();
   if (!session_is_registered('Language')) {
 session_register('Language');
 $Language = 1031;
   }
  
 ?
 
 But all other pages do not have really access to this variable without
 calling start_session() from within the other pages()

You must start session implicitly or explicitly I suggest to start
session explicitly Do not use auto start

 
 If I call, it works
 
 Now the real problem
 
 I would like to set $Language by an Hyperlink with image hyperlinks, but it
 doesnt change anything
 Within the hyperlink I call setlanguagephp?lang=1033
 
 ?php {
   session_start();
   if ( ($lang  1031) and ($lang  1033) ) {
 $lang= 1031; }
   $Language = $lang;
   if (session_is_registered('Language')) {
 session_unregister('Language');
   }
   session_register('Language');
 } ?
 
 But it doesnt change ANYTHING 

What is not changed?

 hi.

 I want to use glabal variable.

 ?
 global $a;

 ?
 but it doesnot work??

... why do you think you need to use global here?

global is used *in a function* to let it see
external variables.  You are not in a function,
so I don't see why you think you need it.

Read References explained section in PHP Manual.
You'll see why it does not work as you expected.

 I have a class that contains a form, when the form is submitted it
 posts back to the class.  The class is included inside of another file,
 so all of the form variables need to be declared as global in order to
 access their values.

 On the form are several check boxes (number undetermined until the
 script is run) and the only way I know to access these values is using
 the variable variables feature of PHP, as follows:

 $A = chkContact.$I;
 $B = $$A;

 This would work just fine if $chkContact## was not a global variable
 (ie..not wrapped inside of a class).  How can I use variable variables
 on a global variable?
