    Here’s a short explanation of the configuration


    When this is turned on, PHP will be allowed to
    operate as a D-COM (Distributed COM) client and will allow the PHP
    script to instantiate COM objects on a remote server.


    When this is turned on, PHP will attempt to
    register constants from the typelibrary of COM objects that it instantiates, if those
    objects implement the interfaces required to obtain that
    information. The case sensitivity of the constants it registers is
    controlled by the configuration directive.


    When this is turned on, any problems with loading a
    typelibrary during object instantiation will be reported using the
    PHP error mechanism. The default is off, which does not emit any
    indication if there was an error finding or loading the type


    When this is turned on (the default), constants
    found in auto-loaded type libraries when instatiating COM objects will be
    registered case sensitively. See com_load_typelib() for more details.


    It controls the default character set code-page to
    use when passing strings to and from COM objects. If set to an
    empty string, PHP will assume that you want
    CP_ACP, which is the default system
    ANSI code page.

    If the text in your scripts is encoded using a
    different encoding/character set by default, setting this directive
    will save you from having to pass the code page as a parameter to
    the COM class
    constructor. Please note that by using this directive (as with any
    PHP configuration directive), your PHP script becomes less
    portable; you should use the COM constructor parameter whenever


    When set, this should hold the path to a file that
    contains a list of typelibraries that should be loaded on startup.
    Each line of the file will be treated as the type library name and
    loaded as though you had called com_load_typelib(). The constants will be
    registered persistently, so that the library only needs to be
    loaded once. If a type library name ends with the string
    #cis or #case_insensitive, then the constants
    from that library will be registered case insensitively.
