Smarty3同梱の「README」ファイルより。

Smarty3でのAPIは以下の通り。
Here is a rundown of the Smarty 3 API:

$smarty->fetch($template, $cache_id = null, $compile_id = null, $parent = null)
$smarty->display($template, $cache_id = null, $compile_id = null, $parent = null)
$smarty->isCached($template, $cache_id = null, $compile_id = null)
$smarty->createData($parent = null)
$smarty->createTemplate($template, $cache_id = null, $compile_id = null, $parent = null)
$smarty->enableSecurity()
$smarty->disableSecurity()
$smarty->setTemplateDir($template_dir)
$smarty->addTemplateDir($template_dir)
$smarty->templateExists($resource_name)
$smarty->loadPlugin($plugin_name, $check = true)
$smarty->loadFilter($type, $name)
$smarty->setExceptionHandler($handler)
$smarty->addPluginsDir($plugins_dir)
$smarty->getGlobal($varname = null)
$smarty->getRegisteredObject($name)
$smarty->getDebugTemplate()
$smarty->setDebugTemplate($tpl_name)
$smarty->assign($tpl_var, $value = null, $nocache = false, $scope = SMARTY_LOCAL_SCOPE)
$smarty->assignGlobal($varname, $value = null, $nocache = false)
$smarty->assignByRef($tpl_var, &$value, $nocache = false, $scope = SMARTY_LOCAL_SCOPE)
$smarty->append($tpl_var, $value = null, $merge = false, $nocache = false, $scope = SMARTY_LOCAL_SCOPE)
$smarty->appendByRef($tpl_var, &$value, $merge = false)
$smarty->clearAssign($tpl_var)
$smarty->clearAllAssign()
$smarty->configLoad($config_file, $sections = null)
$smarty->getVariable($variable, $_ptr = null, $search_parents = true, $error_enable = true)
$smarty->getConfigVariable($variable)
$smarty->getStreamVariable($variable)
$smarty->getConfigVars($varname = null)
$smarty->clearConfig($varname = null)
$smarty->getTemplateVars($varname = null, $_ptr = null, $search_parents = true)

アンダーバーで綴られていたものがcamelCaseになってたり、

  • is_cached() → isCached()

変数に直接代入していたのがgetter/setterを使うように変わったり

  • template_dir → setTemplateDir()

しているっぽいです。


一応後方互換と言うことで、isCached()はis_cached()でも動きますが、以下のNoticeが出ます。

PHP Notice:  function call 'is_cached' is unknown or deprecated. in /usr/lib64/php/Smarty/libs/sysplugins/smarty_internal_wrapper.php on line 57
