Hi List,

I have a function that makes a call to mysql based on certain vars.

---example----

Function MyFunc(){
 if(isset($_POST[var])){
 $sql = mysql_query("select * from table_name where field=\"$_POST[var]\"
");
 $returnsomething ="blah blah";
 }
 return $returnsomething;
}

And that all works fine no probs here but.....

I want to use a result somewhere in my script that is not returned by
return. Let me show you...

---example----

Function MyFunc(){
 if(isset($_POST[var])){
 $sql = mysql_query("select * from table_name where field=\"$_POST[var]\"
");

 $num = mysql_num_rows($sql); // I want to use this result outside this
function.

$returnsomething ="blah blah";
 }
 return $returnsomething;
}

So $num contains a number that I want to use outside the function which is
not covered by return.

I know return stops a script and returns what I want it to return but how do
I send out of the function the var I want.

I have tried $GLOBAL[var]=$num; but that don’t work, but I thought I
would'nt anyway just tried it and yes I know I have to declare it inside my
new function using global $var; to use it.

So I ask is this achiveable or how can I do this.

Thank you in advance

Dave C
