PHP SimpleXML Functions

    PHP supports some SimpleXML extension functions that allow you to use the toolset that converts the XML to an object. Then these objects deal with property selectors and array iterators. These extensions are enabled by default, and you can use the default command line to disable them at the compile time. There is no requirement for the configuration directives to be defined in the php.ini file.
