Ecshop of Unserialize () in initializing the member data integration class

Ecshop in the lib_common.php

/** * Initialize member Data Integration class * * @access public  * @return  object*/function &init_users () {    $set _modules = false;    static $cls = null;    if ($cls! = null)    {        return $cls;    }    Include_once (Root_path. ' Includes/modules/integrates/'. $GLOBALS [' _cfg '] [' Integrate_code ']. '. php ');    $cfg = Unserialize ($GLOBALS [' _cfg '] [' integrate_config ']);    $CLS = new $GLOBALS [' _cfg '] [' Integrate_code '] ($cfg);    return $cls;}

$cfg = Unserialize ($GLOBALS [' _cfg '] [' integrate_config ']);

Global $globals[' _cfg ' [' integrate_config '] This variable is not found, as if there is no definition [' integrate_config '] ah?
What exactly is this step, and what is the value of $cfg?

Find an entire folder search $GLOBALS find

Find an entire folder search $GLOBALS find

In lib_common.php, function load_config () assigns a value to the $globals global variable, but does not find the value $globals[' _cfg ' [' integrate_config '], so doubt,

$cfg = Unserialize ($GLOBALS [' _cfg '] [' integrate_config ']);

Think it should be shop_config. Integrate_config in this data sheet
