Calling components in the page code

Calling components on a site page is implemented with use of the function IncludeFile(). The following parameters are used as the function attributes:

path to the file with required component source code;
properties assigned (by user) for placed on a page component.

<?
// this component displays an information block element detailed information
$APPLICATION->IncludeFile("iblock/catalog/element.php", Array(
    "IBLOCK_TYPE"       => "catalog",                          // Information block type
    "IBLOCK_ID"         => "21",                               // Information block
    "ELEMENT_ID"        => $_REQUEST["ID"],                    // Element ID 
    "SECTION_URL"       => "/catalog/phone/section.php?",      // URL to the information block section page
    "LINK_IBLOCK_TYPE"  => "catalog",                          // Type of information block elements of wich are linked with current element
    "LINK_IBLOCK_ID"    => "22",                               // ID of information block elements of wich are linked with current element
    "LINK_PROPERTY_SID" => "PHONE_ID",                         // Property containing the link between information blocks elements 
    "LINK_ELEMENTS_URL" => "/catalog/accessory/byphone.php?",  // URL to the page with list of linked elements
    "arrFIELD_CODE" => Array(                                  // Fields
         "DETAIL_TEXT",
         "DETAIL_PICTURE"),
    "arrPROPERTY_CODE" => Array(                               // Properties
         "YEAR",
         "STANDBY_TIME",
         "TALKTIME",
         "WEIGHT",
         "STANDART",
         "SIZE",
         "BATTERY",
         "SCREEN",
         "WAP",
         "VIBRO",
         "VOICE",
         "PC",
         "MORE_PHOTO",
         "MANUAL"),
    "CACHE_TIME"        => "3600",                              // Cache time
    ));
?>

Files pertaining to a component can be stored in the following directories:

in the folder of a module to which this component relates (i.e. in the product kernel). For example, the information blocks components are stored in the following folders:
/bitrix/modules/iblock/install/templates/iblock/news/ or /bitrix/modules/iblock/install/templates/iblock/catalog/;
in the folder of site template for which these components were customized. For example:
/bitrix/templates/<template_ID>/iblock/news/ or /bitrix/templates/<template_ID>/iblock/catalog/;
в in the default templates folder. For example:

/bitrix/templates/.default/iblock/news/ or /bitrix/templates/.default/iblock/catalog/.
