php form POST- variable can't increment -



php form POST- variable can't increment -

i'd increment variable on clicking submit button name="ticker".

$speed = 0; if ( isset($_post['ticker'])){ echo $speed++; }

what want able repeatedly click button , see 1 added total each time clicked. seems work 1 time , stays @ "1". why?

session_start(); if(!isset($_session['speed'])) $_session['speed'] = 0; if(isset($_post['ticker'])){ /* if there value set */ $_session['speed']++; /* increment 1 */ }
