I could not find any so I made my own.

But you should always use it when the output of the function do not change so much in caching time. And the output is just a text.

You can not use it if the function returns an array or object. But if it returns an array you can make another wrapper function to convert it from and to JSON instead of an array.

  2.    public function ccache($arrCallable ,$strFilename , $intTTL = ’10 min ago’  , $arrParameter = ”){

  5.         $strCCpath = ‘/tmp/mem/’;

  7.        
  8.         if(file_exists($strFile) and filemtime($strFile) >= strtotime($intTTL) ){
  9.             $strReturn = file_get_contents($strFile);
  10.         }
  11.         else{
  12.             if(is_callable($arrCallable )){
  13.                 if($arrParameter == ”){

  16.                     $strReturn = call_user_func_array($arrCallable , $arrParameter );
  17.                 }
  18.                 file_put_contents($strFile, $strReturn);
  19.                 sf_tools::ccache_Clean(); // this should be from cron

  22.             }
  23.         }
  24.         return $strReturn;
  25.     }
  26.    
  27.     public function ccache_Clean(){
  28.         // mkdir mem
  29.         // mount -t ramfs -o size=250M ramfs /tmp/mem
  30.         // chown www-data mem

How it works

- First you have to put those 2 functions in a class. I have a utility class that I put all those small handy functions in.

- Now log in to your server and make a directory under /tmp called /tmp/mem/

- if you have lots of memory on your server you should mount ramfs to improve the speed. just use mount -t ramfs -o size=250M ramfs /tmp/mem . I assign 250Mb to that. but watch out to not to store bigger files there so it do not exceeds the limit.

- in my UBUNTU server, apache runs as www-data so I changing the owner to www-data. chown www-data /tmp/mem

Now we have set it up,so lets use it.



I have put those functions in my sf_tools class. So when I need to call up the caching system I use sf_tools::ccache(array($this , ‘functionName’) , $strUniqueCachName , ’10 min ago’ );



array($this , ‘functionName’) is the class function I want to cache. So normally I would call it like this $this->functionName()



The second parameter is the unique name for that function so we do not end up overwriting or using the wrong function cache output.



The third is the parameter that feeds the strtotime(). It tells it how long to store the cache. You can use sentences like “10 min ago” or “-1 hour” … check the function sepcs on php.net site. I don’t use more than 10 min by default.



The fourth parameter is the array of parameters to pass to that function that are being cached.



So if you normally call it like this: $this->myCoolFunction($intID,$strText);
, then the caching would be like this:

  1. sf_tools::ccache(array($this , ‘myCoolFunction’) , ‘myCoolFunction’ . $intID . $strText , ’10 min ago’ , array($intID,$strText) );




I use this when I have to do lots of number crunching or when I getting data from other servers by API.

It is much faster and server can save those CPU and Disk resources for other things ;)

Deflating files helps keeping transferring size small. Apache automatically pack the files and your browser unpacks it but the you can save lots of MB a year on transfer size. And it helps the site to load faster on slow connections. This is almost like gziping but deflating method is less CPU aggressive on apache server compared to gzip.

Class name and and file name should have the same name.

Let us say you have a class called “myFirstClass” then your file should be myFirstClass.class.php

Remember to have some kind of comment on top of the file to describe important information about the class like author, version nr or created date.

  1.  
  2. class myFirstClass{
  3.    private $intNumber = 3;
  4.    private $strName = ”;
  5.  
  6.   public function getNumber(){
  7.      return $this->intNumber ;
  8.   }
  9. }
  10.  

Never access the internal variables directly. Use a public function to get or set the value.

  1.  
  2. class someClass{
  3.    private $intValue1 = 0;
  4.    private $intValue2 = 0;
  5.  
  6.    public function getValue1(){
  7.       return $this->intValue1;
  8.    }
  9.  
  10.    public function getValue2(){
  11.       return $this->intValue2;
  12.    }
  13.  
  14. }
  15.  

Use default values instead of passing the same value every time.

  1.  
  2. class someClass{
  3.    private $intValue1 = 0;
  4.    private $intValue2 = 0;
  5.  
  6.    public function getDate($strFormat = ‘Y-m-d’ ){
  7.       return date($strFormat);
  8.   }
  9.  
  10. }
  11.  

Never echo out within a function. It is better to return a value.
This way you can choose what to do with returned value.

  1.  
  2.  
  3. $objSome = new someClass();
  4. $strReturn = ‘Date: <b>’ . $objSome->getDate() . ‘</b><br/>’;
  5. $strReturn .= ‘Week: <b>’ . $objSome->getDate(‘W’) . ‘</b>’;
  6.  
  7. echo $strReturn;
  8.  
  9. class someClass{
  10.    public function getDate($strFormat = ‘Y-m-d’ ){
  11.       return date($strFormat);
  12.   }
  13. }

Let us start with variables.

I use prefix for variables with camel notation. This makes it easy to see and check the right variable for its type.

  1. $strName = ‘ali’ ;
  2. $intCounter = 1;
  3. $arrData = array(‘a’=>‘ali’ , ‘i’=>‘is’ , ‘p’=>‘perfect’);
  4. $blnTrigger = true;
  5. $objMailSender = new mailSenderClass();

I use single quote for my data.

  1. $strMyNameIs = ‘Alireza’;

And I use double quotes for SQL or strings that I need to have a single quote inside.

  1. $strSQL = "SELECT * FROM person WHERE name LIKE ‘ali’ ";

I never use variable inside a double quote string. I break up the quote.

  1. $strCode = "some $bad code ";// WRONG AND UGLY
  2. $strNiceCode = ‘Very ‘ . $strData . ‘ is pasted here’ ;// NICE CODE

Never ever use short variables like $a or $temp or other lazy short names.
Use variable names that are understandable and describe what it contains.
And using a camelNotation makes it easy to read.
Never start with underscore or other kind of separator for names.

  1. $strReturn = ‘Nice code’;

Only use underscore for constants where you can not use tha camel notation.

  1. define(‘FOO_BAR’,‘It works!’);

And do not start with underscore. There are some other system variables and functions that starts with underscore like _get() or $_SESSION

A fat way of making a galery and showing your pictures.

This script finds all the pictures in a directory under ./test_pic/ and makes menus based on directories.

All you have to do is putt your pictures in ./test_pic/ directory. Or edit $strPathToFiles = ‘./test_pic’; in sgl4.class.php file.

You can organize your pictures by category, by putting it under sub-directories.

The thumbs/ directory must be writable (CHMOD 755) to generate thumbnails automatically first time you visit the site. It will help loading your images faster.

HOW TO INSTALL

All you have to do is unzip the file.
Unpack the sgl4.php and configure the paths.

Putt your pictures under ./test_pic/ directory.
And don’t forget to chmod 755 thumbs directory.

SYSTEM REQUIRED.

Server with PHP5.

I use ssh on my server. Rsync is fast way of syncing my files.

Here is the commend line

  1. rsync -vrutzp –exclude=.DS_Store -e "ssh -p 22" /Users/swape/Sites me@myserver.com:/home/mysite

I use:

  • (–exclude=.DS_Store) to exclude the mac files
  • (-e “ssh -p 22″) to use SSH port 22
  • (/Users/swape/Sites) my local directory
  • (me@myserver.com:/home/mysite) my server
  • (-v) verbose mode to see the output
  • (-r) recursive into directories
  • (-u) using update mode
  • (-t) preserve modification times
  • (-z) compress file data during the transfer
  • (-p) preserve permissions

After writing this to my console I enter the password for my server and its done!

This is the fastest way of updating my site from my local disk.
The good thing about this that I use -u so it does not upload the files that have not been changed on my local disk. You can also drop the -v and make an Automator app but then you have to make the public key for your ssh connection so you don’t have to enter the password each time you running the app.

First you have to make a list with UL and LI tags.

  1.  
  2. <ul class="menu">
  3.     <li><a href="http://swape.net">My homepage</a></li>
  4.     <li><a href="http://linux.org">Linux.org</a></li>
  5.     <li><a href="http://google.com">Link to google</a></li>
  6. </ul>
  7.  

Ok here is a list. Now we must make the list items to be horizontal and not vertical. So we must use CSS to set the float to be left and make the list-style: none;

  1. .menu li{ float: left; list-style: none; }

Then we must make them look like a buttons. So we add some borders and padding and margins. Then the whole CSS code look like this:

  1. .menu li{
  2. float: left;
  3. list-style: none;
  4. font: 10px Verdana, Arial, Helvetica, sans-serif;
  5. }
  6. .menu li a {
  7. display:block;
  8. padding:3px;
  9. margin:1px;
  10. border:1px solid #ccc;
  11. text-decoration:none;
  12. color:#332;
  13. background-color: #EEE;
  14. }
  15. .menu li a:hover{
  16. color:#EEE;

FileDate Mover is a program that moves files from one directory to directory tree based on file date. If you have a file that have a date 2006.12.24 then it makes directory called 2006/12/filename.ext.
This program runs through a directory and moves all the files to date-based-directory-tree.
You can edit the i18n.ini file to change the settings.

rprog = datemove.exe -d

If you remove -d, then it moves the files from this month too. But if you use -d, it will ignore files that where made this month.

In the zip file you find these files:

  • i18n.ini settings file.
  • datemove.exe CMD based version of this program. Run datemove in cmd for usage options.
  • datemoveX.exe Gui-based version of this program.
  • src\ Directory containing the sourcefile in php.
