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:

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 ;)

If you know the choices, do not use it directly. Use an array instead.

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.

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

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

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

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.

I use single quote for my data.

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

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

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.

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

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

Here is the commend line

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.

Here is a link to manual on how to make public key http://sial.org/howto/openssh/publickey-auth/

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

• My homepage
• Linux.org
• Link to google

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;

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:

You can download the example file here: Horizontal CSS menu

You put an hidden input before checkbox input with the same name.
Since the last checkbox overwrite the value when it is checked, the hidden input do not return “0″ but when the checkbox is not checked, the hidden input with the same name returns a “0″.

So when the checkbox is checked it returns “on” and when it is not checked it returns “0″

And to make it easier to click on the ckeckbox use “label” tag around the name.

Before:

After:

This way you can click on the checkbox label and make it checked.
The correct way to write an checkbox checked from the start is like this:

And here is the CSS code:

Since IE can not show semi-transparent png images, we have to use the filter style that only works in ie. But if we use this code we have to make sure that other browsers can show the png file as well. So we use the styles with attributes. And since IE can not read this part, we can put everything that IE dose not need to read there.
