An object-oriented way of doing it: keep the extra result in a member variable and
get it separately. You might not find this necessary, but it gets more useful
in more complex cases.
class MyClass {
var $num;
Function MyFunc(){
if(isset($_POST['var'])){
$sql = mysql_query("select * from table_name where field=\"$_POST[var]\"
");
$this->num = mysql_num_rows($sql);
$returnsomething ="blah blah";
}
return $returnsomething;
}
function getCount() { return $this->num; }
}

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 --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
