[SOLVED] global array in function

[-Zeus-]

I know that i can use the command global $var inside a function when the var is already defined, but i have a slight problem.  Here is what i am doing.

 

function dbget($db,$idname,$id,$val) {

$result = mysql_fetch_array(mysql_query("SELECT $val FROM $db WHERE $idname='" . $id . "'"));

              echo $result[$val];

}

This works fine.  However, when I try this:

function dbget($db,$idname,$id) {

                global $result;

$result = mysql_fetch_array(mysql_query("SELECT * FROM $db WHERE $idname='" . $id . "'"));

}

the variable $result is never set.  I tried initing it before calling the var, but that was no good.  Am i doing something wrong?

The point of writing a function is that it returns the result that the code in the function produces - http://us3.php.net/return

it should work !! i tried to do the same thing with sample code and it works..may be there is some problem in function calling or surrounding code.

 

<?php 

$str = "";

function setString($val){
   global $str;
   $str = $val;
}
setString("Test");
echo $str;
?>

 

but yes ! i agree with PFMaBiSmAd

Thanks, I feel stupid.  By putting return(mysql_fetch_array(mysql_query()));, I can now say $result=dbget();

 

Thanks
