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);

}
