Just a quick post today, i needed to redirect a URL with and without a trailing slash to the same destination, but didn’t want to create two separate rules, so I did some searching and found that is is very simple.
RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^video(/)?$ http://video.somedomain.com [R=301,L]
The (/)? is the key to matching a url with or without a trailing slash.
After searching for a good email link obfuscation script that allows the address to be seen as normal text i came upon a webpage that had a good solution, so i did a little reverse engineering and created this PHP script to output the same code, enjoy!
<?php /** * @author Josh Hartman * @copyright 2010 */ function strToHex($string, $prepend=null) { $hex=''; for ($i=0; $i < strlen($string); $i++) { $hex .= $prepend.dechex(ord($string[$i])); } return $hex; } function createRandomPassword() { $chars = "abcdefghijkmnopqrstuvwxyz023456789"; srand((double)microtime()*1000000); $i = 0; $pass = '' ; while ($i <= 7) { $num = rand() % 33; $tmp = substr($chars, $num, 1); $pass = $pass . $tmp; $i++; } return $pass; } function mailto_link($email){ if(preg_match('/^[A-Z0-9._%-]+@(?:[A-Z0-9-]+\\.)+[A-Z]{2,4}$/i',$email)){ $var1 = createRandomPassword(); $var2 = createRandomPassword(); $email = explode('@',$email); $user = strToHex($email[0],'%'); $domain_array = array_reverse(explode('.',$email[1])); $domain = "'"; foreach ($domain_array as $k=>$v){ $domain_array[$k] = strToHex($v,'%'); } $domain = "'".implode("','",$domain_array); $domain .= "'"; $output = $var1."=['".$user."',[".$domain."].reverse().join('.')].join('@');".$var2."=unescape(".$var1.");document.write(".$var2.".link('mai'+'lto:'+".$var1."));"; $output = "<script type=\"text/javascript\">eval(unescape(\"".strToHex($output,'%')."\"));</script>"; echo $output; }else{ return false; //email address is not valid } } mailto_link('username@domain.com'); //use this function wherever you want an email link ?>
In my search for a simple PHP web counter it was difficult to find one that wasn’t somehow connected to an external host and didn’t write IP addresses to a file and then use resources to search the file later. With all the NAT firewalls out there counting visitors based on IP address just doesn’t seem like a modern thing to do. I took a script by Eric Sizemore and modified it to create my own version. What it does is add to the visitor count (stored in a txt file on the server) if they don’t have a cookie showing that they have visited before, then i set that cookie to expire after 60 days, after that if the visitor comes again they will be counted again. It’s not the most accurate, but gives a good idea of how many people are visiting and i wanted to reduce server file operations.
<?php include('counter/counter.php'); ?>
<?php show_counter(); ?>
