Caching the Data using APC – Alternative PHP Cache

Now a days most of the website are used to cache their data to reduce the server load, Also speed up the response. We are going to discuss about the APC – Alternative PHP Cache.

APC is a Alternative PHP Cache as I already mentioned, its used to cache the data, remove and expire in the given time.  To work with APC first we need to enable php_apc.dll in windows and in Linux operating system.

Where to use APC ?

Consider you have a website with lots of content driven from database with data for all the users, on that time you cannot query the database each and every time. To avoid this case we will cache the data and share between the users. This will allow one time query and share the same data between the users.

Let’s see about fews function in APC.

apc_add – function used to store a data in key format and expire it in given TTL.

apc_add ( array $values [, mixed $unused = NULL [, int $ttl = 0 ]] )

Assigning value into $myData variable

    $myData = 'Welcome to APC';

apc_fetch – function used to fetch data from the given key. Continue reading

Persistent and Non-Persistent Cookie

Cookie used to store user data in form of text file or memory and access the values from it, Cookie are the part of HTTP header.

What is Persistent Cookie ?

Persistent Cookie which will store the data in text file with expire date and time. If you are access the website or particular page cookie will be created based on cookie name.  Next time If you are visiting the website or page it will be accessible from the cookie file which was created in the client browser.

Also Persistent Cookie is unsafe, because it will be easy viewable in the browser.


// creating the name:cookie_name_persistent and value:my cookie value with expire 1 hour
setcookie("cookie_name_persistent","my cookie value",time()+3600);

Above PHP file will create cookie and expire within 1 hour, you can view the cookie expire time in browser cookie part. Continue reading
