Question

Background: I\'ve got some code that checks to see if a user has a valid session before processing the php page that I would like to set as the auto_prepend_file. However,

Answer 1

There is a great tutorial called: Automatically Include Files with PHP & Apache that explain how to do that with the apache directive and PHP code to append at the end. First, define a file to catch the page before it's outputted and append whatever you want:

<?php
{
  $script = <<<GA
<script type="text/javascript">
  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-xxxxxxxxx-y']);
  _gaq.push(['_trackPageview']);

  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
  })();
</script>
GA;
  $replace = array('</body>','</BODY>');
  $page = str_replace($replace, "{$script}\r</body>", $page);
//   $replace2 = array('</title>','</TITLE>');
//   $page = str_replace($replace2, " - My Awesome Site</title>", $page);
  return $page;
}
ob_start("appendToFile");
?>

Then add the Apache directive to your virtual host. You need to prepend the PHP file in order to use the ob_start() method :

<Directory "/path/to/folder">
    AddType application/x-httpd-php .html .htm
    php_value auto_prepend_file /absolute/path/to/apache-prepend.php
</Directory>

Answer 2

Use .user.ini files.

Answer 3

You mention you can't use .htaccess files but can you make modifications to httpd.conf and do something like this:

<Directory "c:/wamp/www/dev/">
    Php_value auto_prepend_file c:/wamp/www/dev/prepend.php
</Directory>

EDIT - just realised this doesnt work when running as CGI. I think though that one thing that will work is if you create a copy of your php.ini file, place it in the directory, and put your prepend directive in there like:

auto_prepend_file = c:/wamp/www/dev/prepend.php
