The IntlChar::enumCharNames() function is an inbuilt function in PHP which is used to give a catalog of all the assigned Unicode characters that are available within a range. The list will have the Unicode characters that are available between the start code points (start inclusive) and the limit code points (limit exclusive). A function is going to be called for each and the code point value will be passed on along with the character name. Those who are different from the new & modern names, only those will get cataloged, for Unicode 1.0 names.
