If you just need a grammar, then I would not suggest to use the one
from phpcompiler.org. They use a YACC grammar that is directly based
on the YACC grammar of the PHP distribution, so you can just as well
use the PHP grammar then. One advantage of the PHP compiler front-end
is that they also support XML output, which might be convenient for
connecting the parser to your tools.

There is also a JavaCC grammar for PHP, which might be easier to start
with if you want to develop a grammar for ANTLR (considering that
JavaCC is LL and YACC is LALR). The JavaCC grammar is however not
complete.

See: http://cobase-www.cs.ucla.edu/pub/javacc/

The reason why I am interested in PHP grammars is that we are
developing a PHP grammar for SDF, which is implemented using a
Generalized-LR parser. The grammar is reasonably feature complete (and
has very cool features for parsing string literals), but is not
completely compatible concerning the precedence of operators (it's a
bit more restrictive than standard PHP). The tools based on this can
output XML as well, but I don't want to push it too much on this ANTLR
list ;)
