A Slice identifier maps to an identical PHP identifier. For example, the Slice identifier
Clock becomes the PHP identifier
Clock. There is one exception to this rule: if a Slice identifier is the same as a PHP keyword or is an identifier reserved by the Ice run time (such as
checkedCast), the corresponding PHP identifier is prefixed with an underscore. For example, the Slice identifier
while is mapped as
You should try to avoid such identifiers as much as possible.
A single Slice identifier often results in several PHP identifiers. For example, for a Slice interface named
Foo, the generated PHP code uses the identifiers
FooPrx (among others). If the interface has the name
while, the generated identifiers are
_whilePrx), that is, the underscore prefix is applied only to those generated identifiers that actually require it.
