DeTypo in PHP

Published by shopzz on July 21, 2007 under SEO, PHP

Sometimes we need to detect mistypes :)
We can use google-search to make sure if given word is a mistype, here my solution:

  1. if($_GET['key']!=''){
  2.   $key=$_GET['key'];
  3.   $s=GetData('http://www.google.com/search?q='.urlencode($key));
  4.   if(strstr($s, '&spell=1 class=p><b><i>')){
  5.     $s=substr($s, strpos($s, '&spell=1 class=p><b><i>')+strlen('&spell=1 class=p><b><i>'));
  6.     $s=substr($s, 0, strpos($s, '</a>'));
  7.     $key=strip_tags($s);
  8.   }
  9.  
  10.   echo $key;
  11. }
  12.  
  13. function GetData($url){
  14.  $ch=curl_init();
  15.  curl_setopt($ch, CURLOPT_URL, $url);
  16.  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  17.  curl_setopt($ch, CURLOPT_TIMEOUT, 15);
  18.  $out=curl_exec($ch);
  19.  curl_close($ch);
  20.  
  21.  return $out;
  22. }

Deny https from search engines indexing

Published by shopzz on July 19, 2007 under SEO, Apache

Well, if you have such problem, let’s do the following:

  1. Create two files:
    1. robots.txt:
      User-agent: *
      Allow: /
    2. robots-https.txt:
      User-agent: *
      Disallow: /
  2. Now write in your .htaccess this:
    RewriteEngine on
    RewriteCond %{HTTPS} on
    RewriteRule ^robots\.txt$ robots-https.txt

That’s all :) Have a nice day.

The top of most important Unix commands…

Published by shopzz on June 25, 2007 under Unix

To learn Unix isn’t too simple idea, so let’s consider the most important unix commands:

  1. cd - Change directory, example: cd /etc/
  2. ls - List directory, example: ls /etc, use ls -l /etc to see more detail
  3. cp - Copy a file or directory, example: cp source dest if you want to copy a directory use the -R option for recursive: cp -R /source /dest
  4. mv - Move a file, example: mv source dest
  5. rm - Remove a file, example: rm somefile to remove a directory you may need the -R option, you can also use the -f option which tells it not to confirm each file: rm -rf /dir
  6. cat - Concatenate, or output a file cat /var/log/messages
  7. tar - Archiver. Usage example:
    gunzip -d archive.tar.gz - makes from archive.tar.gz => archive.tar
    tar xvf archive.tar - this will extract archive.tar to current directory.
  8. vi - Text editor, example: vi ./file.txt
    To edit a line press Esc i then to save changes and exit use Esc wq, or to quit without saving use Esc q!.
  9. man - Show manual for a command, example: man ls hit q to exit the man page.
  10. top - This command provides a good overview of things including CPU and memory utilization, and a list of the top consumers of CPU. If you want to kill some process press “K” and enter id of process.
  11. wget - Download something frm other server. Example: wget http://www.shopzz.org/robots.txt
