array_unshift --
Prepend one or more elements to the beginning of an array
Description
int array_unshift ( array &array, mixed var [, mixed ...] )
array_unshift() prepends passed elements to
the front of the array. Note that the list
of elements is prepended as a whole, so that the prepended
elements stay in the same order. All numerical array keys will be
modified to start counting from zero while literal keys won't be touched.
