Recently I needed to speed up the project that makes a lot of sevices call, like rss import, twitter, recapatcha  etc. and some database calls.  To solve this caching is the answer.  Fortunately there is Zend_Cache that provides fast and easy function to do so.

First, you need a create directory which the cached files will be saved, i.e (tmp) and make rewritable (777), then the following of code lines will be place at the top of your bootstrap.php

// application/bootstrap.php

protected function _initCache()
{
    $frontendOptions = array(
        'lifetime' => 86400, // timestamp equivalent of 1 day
        'debug_header' => false, // for debugging
  	'default_options' => array(
	    'cache_with_cookie_variables' => true,
	    'make_id_with_cookie_variables' => false
            ),
        'regexps' => array(
      	    // cache all controllers
            '^/$' => array('cache' => true),
	    // cache the whole IndexController
            '^/index/' => array('cache' => true),
	    )
	);

    $backendOptions = array(
        'cache_dir' => 'tmp'
        );

    // getting a Zend_Cache_Frontend_Page object
    $cache = Zend_Cache::factory('Page',
                                 'File',
	                          $frontendOptions,
	                          $backendOptions);
     $cache->start();
     // if the cache is hit, the result is sent to the browser and the
     // script stop here
     // [...] the end of the bootstrap file
     // these lines won't be executed if the cache is hit
}

This is only the basic caching that I can provide right now, will update sooner.

To test whether two variables are different, use any one of PHP’s many comparison operators.

<php

// define some variables
$mean   = 29;
$median = 40;
$mode   = 29;

// less-than operator
// return true if  left side is less than right
// return true here
$result = ($mean < $median);

// greater -than operator
// returns true if left side is greater than right
// return false here
$result = ($mean > $median);

// less than or equal to operator
// return true if left side is less than or equal to right
// return false here
$result =($median <= $mode);

// greater than or equal to operator
// return true if left side is greater than or equal to right
// return true here
$result = ($median >= $mode);

// equality operator
// return true if left side is equal to right
// return true here
$result = ($mean==$mode);

// not equal to operator
// return true if left side is not equal to right
// return true here
$result = ($mean != $mode);

// inequality operator
// return true if left side is not equal to right
// return true here
$result = ($mean <> $mode);

?>

To find out what type a particular variable is,PHP offers the gettype() function, which accepts  a variable or value as argument.The following example illustrates this:

<?php

// define variables
$auth  = true;
$age   = 27;
$name  = 'Bobby';
$temp  = 98.6;

// returns String
echo gettype($name);

// return bolean
echo gettype($auth);

//return integer
echo gettype($age);

//return double
echo gettype($temp);

?>

PHP also supports a number of specialized functions to check if a variable or value belongs to a specific type.

Are you little confused configuring the table prefix in zf? Still I don’t why, why there is no default configuration on zend framework to set up the table prefix, if you have an idea please share with us. Ok, well let’s start to configure it manually.

First add an addition line

//application/configs/application.ini

; Database connection
resources.db.adapter = PDO_MYSQL
resources.db.params.host = localhost
resources.db.params.username = root
resources.db.params.password = password
resources.db.params.dbname = database
resources.db.params.prefix = my_
resources.db.isDefaultTableAdapter = true

You can replace the default WordPress smilies with this gifs pack and I would like to share it with you.

To change the core smilies from wordpress, click the button below to download the zip file.

Then  overwrite – under the directory

wp-includes/images/smilies


It will be look like these    

Thats all, hope it will help.

Every language has different types of variables- and PHP has no shortage of choices.The language supports a wide variety of data types,including simple numeric characteristic,string and Boolean types,and more complex arrays and objects.

Here is my commonly used commands using unix “vi” in general, it’s very useful especial when you’re creating and maintaining cron script on unix server.

Zend Server Community Edition(ZSCE) is one of the common useful tool uses by any zend developer.

The following are the list features of ZSCE

• Native installation – Windows MSI, Debian deb, Red Hat yum installation
• Certified PHP
• Zend Framework – ZF installation and updates as part of the native installation package
• Apache or IIS integration
• Java connector – Integrates existing Java functionality as PHP code
• Web-based administrator console
• Debugger interface
• Bytecode acceleration – Keeps compiled code in shared memory, increasing performance by reducing disk access and CPU processing time
• Data Caching API

So why don’t give ZSCE a try ?
