challenge have faced is, couldn't keep $guesscount stable always. keeps resetting on me. have tried session couldn't resolve it.please resolving it. in advance.
i don't know why gut feeling tells me reason why session not working on other pages because not initiate ??
so have is:
index.php
<?php session_start(); $_session['myvariable'] = 'myvariable'; ?> page1.php
<?php session_start(); $mysessionvar = $_session['myvariable']; var_dump($mysessionvar); // <- should print myvariable ?> you may error saying $_session null or not set , prevent can enclose $_session inside , isset method
if(isset($_session['myvariable']) && $_session['myvariable'] != null) { $mysessionvar = $_session['myvariable'[; }
