static variable declaration

hello everybody, I am having one doubt in static variable declaration,whether static variable works only with in the function if that function is called more than one times.this is my code facind problem. STATIC $m=0; if($m==0): $m=$m+1; print "<a href=\"tradesummary_pg2.php?m=$m\">next</a>"; elseif($m<($k-1)): print "<a href=\"tradesummary_pg2.php?m=$m-1\">previous</a><a href=\"tradesummary_pg2.php?m=$m+1\">next</a>"; else: print "<a href=\"tradesummary_pg2.php?ID=$ID&m=$m-1\">previous</span></td><td></td></tr>"; endif; u have seen yahoo mail inbox with Next ,previous links in bottom. i want to implement same functionality locally.i did my coding and i am facing a problem, that when i click the next link $m value incremented to 1 for first time and when i click next for second time ,$m value is not incrementing,i declared $m as STATIC .i am looking forward suggestions from ur any one.
