Passing variable between functions on the same page

[nshack31]

I have a function (below). The part I am confused abbout is the variable $cnt (in bold). I wish to use this variable in another function that is on the same PHP page, how can I pass the $cnt variable onto another function in the same page? I keep gettin the undefind variable message! Thanks

 function getDateLink($day, $month, $year)
 {
include 'open.php';
$query="Select * From challenge Where confirmed = 'Yes' AND month = '$month' AND year = '$year'";
$result = mysql_query($query);
$teamday='';
$teammonth='';
$teamyear='';
$link = '';
$cnt = 0;
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{ 
$teamday[]=$row['day']; 
$teammonth[]=$row['month'];
$teamyear[]=$row['year']; 
[b]$cnt++;[/b]
if(in_array($day,$teamday) and in_array($month,$teammonth) and in_array($year,$teamyear))
 {
 $link = "displaymatches.php?day=$day&month=$month&year=$year";
 }
 
}
return $link;
include 'close.php';
 }

There's a thread in the forum library [webmasterworld.com] which is sort of a beginner's guide to functions and variable scope [webmasterworld.com].

I think that will help you get it sorted. See especially messages #2 and #7
