The upper case is often used to represent the following:

* The golden ratio conjugate −0.618... in mathematics.

* The magnetic flux and electric flux in physics, with subscripts distinguishing the two.

* The cumulative distribution function of the normal distribution in mathematics and statistics.

* In philosophy, Φ is often used as shorthand for a generic act.

* The number of phases in a power system in electrical engineering, for example 1Φ for single phase, 3Φ for three phase.

* A common symbol for the parametrization of a surface in vector calculus.

* In Lacanian algebra, Φ stands for the imaginary phallus and also represents phallic signification; -Φ stands in for castration.

DOM : is a cross-platform and language-independent interface that treats an XML or HTML document as a tree structure wherein each node is an object representing a part of the document.

The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects.

DOM methods allow programmatic access to the tree; with them one can change the structure, style or content of a document.

Nodes can have event handlers attached to them. Once an event is triggered, the event handlers get executed.

The principal standardization of the DOM was handled by the World Wide Web Consortium, which last developed a recommendation in 2004.

WHATWG took over the development of the standard, publishing it as a living document.

The W3C now publishes stable snapshots of the WHATWG standard.
