You can get the value of a constant by simply specifying its name.
Unlike with variables, you should <emphasis>not</emphasis> prepend
a constant with a <literal>$</literal>.
You can also use the <function>constant</function>-function, for
example if the name of the constant is variable.
You can also use the function <function>constant</function>, to
read a constant's value, if you are to obtain the constant's name
dynamically.
Use <function>get_defined_constants</function> to get a list of
all defined constants.
