$Smarty->display("footer.tpl");
function GetMicrotime()
{
$microtime = microtime();

$microtime = explode(" ", $microtime);

$microtime = doubleval($microtime[1]) + doubleval($microtime[0]);

return $microtime;
}

function TimePassed($stardebug, $length = 3)
{
$endtime = GetMicrotime();

$time_passed = ($endtime - $stardebug) * 1000;

$time_passed = number_format($time_passed, $length, ".", "");

return $time_passed;

You must assign variables to the template before calling it. Try this:

$stardebug = GetMicrotime();
$Smarty->assign('stardebug', $stardebug);
$Smarty->display("footer.tpl");

If you are interested specifically in timing, this might be useful as well:

Thank You Very Much . Thanks For You Help .

I test your code .

Smarty error: [in main.tpl line 9]: syntax error: unrecognized tag 's_math' (Smarty_Compiler.class.php, line 551)

I don't know why . I am new for Smarty .

I view some topics of yours , Say PEAR::DB is slow ? Yes ! Do nothing but pass 50 or more ms .... only for include mysql.php file . I don't know how is Smarty .

Hi ShenKong,

s_math is another plugin which you can find in the plugin forum. It is not required to use the timeblock plugin--I included it in my example mainly because I wrote the timeblock plugin to compare the speed of the s_math plugin to the built-in math functionality of the older 2.5.0 version of Smarty. Smile

I have been using DBX as my db abstraction layer -- it is thin, fast and as a module, has no significant start-up time. Unfortunately, it may not be available on all hosts since it is not enabled by default.

As for Smarty's performance, it is considered good as far as PHP template engines go. A nice thing about Smarty is that it only loads its plugins (and even parts of its core engine) when those parts are required, helping reduce overall load times. The caching feature can also help reduce overall load.

cheers!

Thanks ..

I consider SQLite will be popular . Yestoday I viewed someting about it . It seems very good . Compare with ASP/Access , future the application must be easy to install . but now install a PHP application with MySQL (or other DBMS) is hard for some people .........en , so I must choose a db abstraction layer if future I change DBMS mybe easy and modify code few . . . May PHP5 enable DBX by default ? They should make DBX perfect , Its funtions are few . But I saw a topic written by Zeev , he said DBX will be use by default db abstraction layer ,is that true ? I can't found that topic now , it is on zend.com / ask a question for php5/ .

My English is poor .. Very Happy

hope you can understand .

There are few informations about PHP with Chinese ... Cool

Thanks .

Another question :

I have some DB queries , I use cache like this:

[php:1:c7df4009d5]
<?php
$Smarty->caching = 1;
$Smarty->cache_lifetime = 300;
//................................
// ........DB queries ........
//................................

$Smarty->display("main" . TPL);
?>
[/php:1:c7df4009d5]
but , It doesn't do what I want . The DB query also run after the cache files exist..... Do I need to add the DB query in the tpl files ? Or any other ways? Thanks for your work on Smarty .

hi again.

hmm, is_cached() works perfectly. Did you set-up you cache directory?

ShenKong · Smarty Rookie Joined: 20 Jan 2004 Posts: 27

yes , all cache files exist .
in cache dir . file name is : chi-^chi-^%%192^%%1926952680^main.tpl , a html page .
in templates_c dir , file name is : chi-^%%192^%%1926952680^main.tpl.php
but is_cached() can't detect the cache file I think .

by the way , I use a language class extends Smarty .:

Watch codes is very tired ... Now everything seems OK .

Add these codes in smartyML class :
[php:1:e2644ac148] function is_cached($_smarty_tpl_file, $_smarty_cache_id = null, $_smarty_compile_id = null) {
// We need to set the cache id and the compile id so a new script will be
// compiled for each language. This makes things really fast Wink

$_smarty_compile_id = $this->language->getCurrentLanguage().'-'.$_smarty_compile_id;
$_smarty_cache_id = $_smarty_compile_id;

// Now call parent method
return parent::is_cached( $_smarty_tpl_file, $_smarty_cache_id, $_smarty_compile_id);
}[/php:1:e2644ac148]

mmh~~ One suggestion For smarty.class.php

Line 1728
[php:1:ab8ff207e9] if (!($fd = @fopen($filename, 'r'))) {
return false;
}[/php:1:ab8ff207e9]

Change as
[php:1:ab8ff207e9] if (file_exists($filename)) {
$fd = @fopen($filename, 'r');
} else {
return false;
}[/php:1:ab8ff207e9]
