Hello,

Does anyone know what are the official names for the "->" and "=>"
operators? They don't seem to be included in the PHP documentation,
although I would have expected them to reside in the Operators section of
the manual.

Also, the "\" operator used for declaring sub-namespaces is never mentioned
as a proper operator in the PHP manual, let alone have a specific name.

Thank you,
Adrian

You should take a look at <http://php.net/tokens>.

Best regards.

The tokens are `T_OBJECT_OPERATOR` and `T_DOUBLE_ARROW` respectively, if
that helps: http://www.php.net/manual/en/tokens.php

The namespace operator is T_NS_SEPARATOR.

Hope that helps,

=> is not exactly operator, it's part of the array operator syntax (e.g. 
array($foo => $bar) produces array from two vars, => by itself is not 
used). -> is usually called an arrow operator.

\ is not an operator either, it's a namespace separator.
