Paamayim Nekudotayim
From Wikipedia, the free encyclopedia
The Scope Resolution Operator (::) in PHP is officially called Paamayim Nekudotayim (IPA: [paʔamajim nəkudotajim]). It means 'twice colon' or 'double colon' in Hebrew.
[edit]
Etymology
Nekudotayim (נקודתיים) means 'colon'; it comes from nekuda (IPA: [nəkuda]), 'point' or 'dot', and the dual suffix ayim (יים-), hence 'two points'. Similarly, the word paamayim (פעמיים) is derived by attaching the dual suffix to paam (IPA: [paʔam]) ('one time' or 'once'), thus yielding 'twice'.
The name was introduced in the Zend Engine 0.5 used in PHP 3. Although it has been confusing to many developers, it is still being used in PHP 5, as in this sample error message:
Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM in...
