[PHP] Precedence question- cookie value over form value?

[Dexter]

Hi PHPers,

If I have a script that checks to see if a variaable is defined. The variaable is from 
a form and is sent to the script. There is also a cookie that may be set with a name 
as the same name as from the form. When the script checks and assuming the cookie is 
set and a value sent from the form , which value does the variable take on?

Thanks

[PHP] Globalness of variables? Functions & subs

[Dexter]

Hi PHPers,


I noticed that you have to use keyword "global" in front of globla var.- (one declared 
at the top of a  script outside any functions ) in order to access it inside a 
function. So merely designating a var. global is a little more involved than say Perl 
or other languages. You actually have to tell PHP that the function is global.

I see functions , are there subroutine calls. I guess not. A function acts as a 
sub when it returns no value . A sub that returns a value is a function.

[PHP] Does the array parameter of ereg actually return strings matched?

[Dexter]

Does the array parameter of ereg actually return strings matched? I tried to read a 
file looking for a string using

ereg and wanted to put the matched strings found in an array. Doesn't seem to

be happening with the following.



 $contents=fread($readfile,10);

 $pattern="";
$i=0;
  while(!feof($readfile))
   {

 $contents=fgets($readfile,4065);

if(eregi($pattern,$contents,$regs))
 {   echo "$regs[$i]";
  }
 $i++;
    }


Thanks

Dexter
