HOW to pass php variable from one page to other

[psyphil]

I have 3 pages a.php ,b.php and c.php .How can I use the variable of b.php in c.php


a.php

<script type="text/javascript">
var width;
width = screen.width;
if (width > 0) {
location.href = "b.php?width=" + width;
} else 
    exit();
</script>

<script type="text/javascript"> var width; width = screen.width;
 if (width > 0) { location.href = "b.php?width=" + width; }
 else exit(); </script>

b.php

<?php

if($_GET['width'])
{
public $screen_width;
$screen_width=$_GET['width'];
}

else
{
include("a.php");
}
?>

<?php if($_GET['width']) { public $screen_width;
 $screen_width=$_GET['width'];
 }
 else { include("a.php"); } ?>

c.php

<?php 
global $screen_width;

 if($screen_width>1024)
{
.....
}

else

{...

}

?>

<?php global $screen_width;
 if($screen_width>1024) { ..... } 
else {... } ?>

Help me guys,I can't use include() since a.php has js that keeps reloading everytime and c.php will be redirected to c.php?width=...

Hi..

you can use cookie to store value..

1. $width=$_COOKIE["width"];
2. You can use hidden field also
($width=$_GET['width']; )
ie, <input name="id1" type="hidden" value="<?php echo $width;?>"> //if you are using html in b.php

When a visitor visits c.php I want php to go to b.php and send the variable to c.php ,Is that possible using cookies

use sessions, much simpler and your not sending your data across the net multiple times
