<?php // IMPORTANT *************************************************

/* 

  INFORMATION:

  This script should not be used in its complete form. Instead, only 

  the needed script blocks should be employed. For example, let's say

  you made a site that renders great in all browsers, yet, for some 

  odd reason it doesn't look right in Opera 9. In such a case you have

  a couple of options: You can just go into your CSS, locate, and fix

  the problem, assuming that is you can do so without messing up the

  styles in other browsers. Another option, one using this script, is

  to create a handful of specific CSS rules/properties to address the

  discrepancy and return a link to a special style sheet with said 

  information on it or simply return those styles directly to the head

 (below the main CSS link so it effectively overrides the default 

  styles). I made this script because, unlike Internet Explorer 

  browsers, a conditional comment cannot be used to call or link a 

  special CSS on most browsers. Moreover, some of the other methods 

  for linking special styles/style sheets is complicated at best. 

  This method is really designed for Opera browsers and some Mac 

  browsers like IE 5.2 for Mac, but you can use it for any browser, 

  even IE should you choose to employ this method instead of using a

  conditional comment.



  EXPERIMENT PAGE DISCLAIMER

  The script used on the experiment page is far more complicated than

  it needs to be, but since I wanted to actually return your browser 

  info to you when you visit (plus to help me determine what's working

  and what's not), I had to add a lot of scripting. And it's not complete.

  It works is nearly everything I tested on, but more versions, builds, 

  and revisions yet to be will render it obsolete in the future. Script

  blocks will have to be added to keep it current. However, browsers are 

  getting better so it is backwards compatibility that is of the most 

  importance. If you find something I'm missing, please let me know and 

  be to send me what you're using and the HTTP User Agent data (first box).



  USAGE INSTRUCTIONS

  I will use the Mac IE 5.2 browser for example. Let's say it needs 

  special styles that need to be linked to or returned to the page on

  which they're needed. Here's how it's meant to be used:



  1) To link a style sheet:



     <?php 

     // First grab the HTTP User Agent info and it becomes the $ua_ok variable

        $ua_ok= $_SERVER['HTTP_USER_AGENT'];

     // Now create a condition which only outputs the link if there is a browser match

        if( eregi( "Mac_PowerPC", $ua_ok ) && 

            eregi( "msie", $ua_ok ) && 

            eregi( "[5]\.[2][0-9]", $ua_ok ) ) {

        echo ( '<link rel="stylesheet" type="text/css" href="styles/MacIE52.css" media="screen" />' );

        }

     ?>



  2) To return CSS to the head:



     <?php

     // First grab the HTTP User Agent info and it becomes the $ua_ok variable

        $ua_ok= $_SERVER['HTTP_USER_AGENT'];

     // Now the create a condition which only outputs the CSS info if there is a browser match

        if( eregi( "Mac_PowerPC", $ua_ok ) && 

            eregi( "msie", $ua_ok ) && 

            eregi( "[5]\.[2][0-9]", $ua_ok ) ) {

        echo ( '<style type="text/css" media="screen" >

                  body {

                    /* some_unique_style_info_for_body_in_this_example */

                  }

                </style>' );

        }

     ?>



  That's it. Be sure the script is placed in the <head></head> and that it

  comes AFTER the normal CSS link so it overrides it.



  Below are the other script blocks I've created thus far (Dec 19th, 2007)



  NOTE: This script will not be supported in PHP6 because of ereg()/eregi() isn't

        supported. With PHP6 you'll have to use preg_match('(MATHCHES HERE)i'); 

        The lowercase i, like the ereg() function, makes it case-insensitive.
