A few examples of Cache_Lite using :

------------------------------------

>>> Basic one :

<?php

// Include the package

require_once('Cache/Lite.php');

// Set a id for this cache

$id = '123';

// Set a few options

$options = array(

    'cacheDir' => '/tmp/',

    'lifeTime' => 3600

);

// Create a Cache_Lite object

$Cache_Lite = new Cache_Lite($options);

// Test if thereis a valide cache for this id

if ($data = $Cache_Lite->get($id)) {

    // Cache hit !

    // Content is in $data

    // (...)

} else { // No valid cache found (you have to make the page)

    // Cache miss !

    // Put in $data datas to put in cache

    // (...)

    $Cache_Lite->save($data);

}

?>

>>> Usage with blocks

(You can use Cache_Lite for caching blocks and not the whole page)

<?php

require_once('Cache/Lite.php');

$options = array(

    'cacheDir' => '/tmp/',

    'lifeTime' => 3600

);

// Create a Cache_Lite object

$Cache_Lite = new Cache_Lite($options);

if ($data = $Cache_Lite->get('block1')) {

    echo($data);

} else {

    $data = 'Data of the block 1';

    $Cache_Lite->save($data);

}

echo('<br><br>Non cached line !<br><br>');

if ($data = $Cache_Lite->get('block2')) {

    echo($data);

} else {

    $data = 'Data of the block 2';

    $Cache_Lite->save($data);

}

?>

A few examples of Cache_Lite_Output using :

-------------------------------------------

>>> Basic one :

<?php

require_once('Cache/Lite/Output.php');

$options = array(

    'cacheDir' => '/tmp/',

    'lifeTime' => 10

);

$cache = new Cache_Lite_Output($options);

if (!($cache->start('123'))) {

    // Cache missed...

    for($i=0;$i<1000;$i++) { // Making of the page...

        echo('0123456789');

    }

    $cache->end();

}

?>

>>> Usage with blocks :

(You can use Cache_Lite_Output for caching blocks and not the whole page)

<?php

require_once('Cache/Lite/Output.php');

$options = array(

    'cacheDir' => '/tmp/',

    'lifeTime' => 10

);

$cache = new Cache_Lite_Output($options);

if (!($cache->start('block1'))) {

    // Cache missed...

    echo('Data of the block 1 !<br>');

    $cache->end();

}

echo('<br><br>Non cached line !<br><br>');

if (!($cache->start('block2'))) {

    // Cache missed...

    echo('Data of the block 2 !<br>');

    $cache->end();

}

A few examples of Cache_Lite_Function using :

---------------------------------------------

>>> With function :

<?php

require_once('Cache/Lite/Function.php');

$options = array(

    'cacheDir' => '/tmp/',

    'lifeTime' => 10

);

$cache = new Cache_Lite_Function($options);

$cache->call('function_to_bench', 12, 45);

function function_to_bench($arg1, $arg2)

{

    echo "This is the output of the function function_to_bench($arg1, $arg2) !<br>";

    return "This is the result of the function function_to_bench($arg1, $arg2) !<br>";

}

?>

>>> With method :

<?php

require_once('Cache/Lite/Function.php');

$options = array(

    'cacheDir' => '/tmp/',

    'lifeTime' => 10

);

$cache = new Cache_Lite_Function($options);

$obj = new bench();

$obj->test = 666;

$cache->call('obj->method_to_bench', 12, 45);

class bench

{

    var $test;

    function method_to_bench($arg1, $arg2)

    {

        echo "\$obj->test = $this->test and this is the output of the method \$obj->method_to_bench($arg1, $arg2) !<br>";

        return "\$obj->test = $this->test and this is the result of the method \$obj->method_to_bench($arg1, $arg2) !<br>";

    }

}

?>

>>> With static method :

<?php

require_once('Cache/Lite/Function.php');

$options = array(

    'cacheDir' => '/tmp/',

    'lifeTime' => 10

);

$cache = new Cache_Lite_Function($options);

$cache->call('bench::static_method_to_bench', 12, 45);

class bench

{

    var $test;

    function static_method_to_bench($arg1, $arg2) {

        echo "This is the output of the function static_method_to_bench($arg1, $arg2) !<br>";

        return "This is the result of the function static_method_to_bench($arg1, $arg2) !<br>";

    }

}

?>

>>> IMPORTANT :

If you try to use Cache_Lite_Function with $this object ($cache->call('this->method',...)

for example), have a look first at :

A few examples of Cache_Lite_File using :

-----------------------------------------

<?php

$options = array(

    'cacheDir' => '/tmp/',

    'masterFile' => '/home/web/config.xml'

);

$cache = new Cache_Lite_File($options);

// Set a id for this cache

$id = '123';

if ($data = $cache->get($id)) {

    // Cache hit !

    // Content is in $data

    // (...)

} else { // No valid cache found (you have to make the page)

    // Cache miss !

    // Put in $data datas to put in cache

    // (...)

    $cache->save($data);

}

?>
