    accessing variable value

    i need help with accessing the value of a variable from a different page.

    i have an index.php file which has 2 files included to display header and footer and the center portion changes based on the link clicked on the footer.

    header.php

    <?php
    echo "<h2> Text from header.php file </h2>";
    ?>

    footer.php

    <?php
    $title="Title of Footer Page";
    ?>
    <a href="index.php ?page=web">Web Development</a> | <a href="index.php ?page=software" >Software </a>

    index.php

    <?php
    $pagename=$_GET["page"];
    $title="Index page of Company name";
    ?>
    <html>
    <head>
    <title><?php echo $title; ?> </title>
    <meta name="keywords" content="<?php echo $keyword; ?>">
    <meta name="descripti on" content="<?php echo $pagedescriptio n; ?>">
    </head>
    <body>
    <?php include("header .php"); ?> <p> </p>
    <center>This is the text in the center</center> <p> </p>
    <?php
    if($pagename==" web")
    {
    include("web.ph p");
    }
    if($pagename==" software")
    {
    include("softwa re.php");
    }
    ?>
    <?php include("footer .php"); ?>
    </body>
    </html>

    whenever i click the links for Web Development or Software which appears from the footer a query string is passed to index.php I am able to display the content of web.php and software.php using the if() condition and include()
    what i need to display is a different title for web.php and software.php when a user clicks Web Development along with the content i want the title of the page to change for SEO purpose. i have defined $title differently in web.php and software.php however presently the title being displayed for index.php when a user clicks web.php and software.php the title is the same
    "Index page of Company name" as this is defined in index.php and my title tag is written as
    <title><?php echo $title; ?> </title> however the title tag remains the same whether i click web development or software link. how change i change the code to display different titles.

    i am doing this for SEO purpose so that different pages have different titles and meta tags.

    actually there can be individual files with links to individual pages however the people i am dealing with who developed the website want the header and footer to remain so that a flash file does not have to load each time an individual link is clicked.

    please advice.

    thanks

    Your logic is barmy. I think you need to read at least one php web deveplopment book.
    You cannot expect a variable to be in scope from a file that is included later.
    And you certainly can't change the header information already sent to the browser

    Instead of the link calling itself why not link to the required scripts - web.php or software.php where each can have its own header information.

    You should try to write scripts that keep the php logic and the html display in seperate files.
    This makes for easier maintenance
