The traditional point movement commands for
Emacs<a rel="footnote" href="#fn-1" name="fnd-1"><sup>1</sup></a> and Emacs's C mode<a rel="footnote" href="#fn-2" name="fnd-2"><sup>2</sup></a> are supported in PHP mode. The following are
noteworthy commands for working on PHP code or are
extensions expressly provided by PHP mode.
<dl>
<!-- The forward-sexp command isn't optimally named nor -->
<!-- behaved for a language like PHP, but it comes for free -->
<!-- (gratis) from Emacs, and may prove useful. It would be -->
<!-- better to have a php-forward-syntax command that follows -->
<!-- the parsing rules of PHP and not a lisp language. For -->
<!-- instance, if at the beginning or end of a statement, move -->
<!-- to the next statement. The syntaxes that would be useful -->
<!-- to move across would need to be researched. -->

If point is in a string literal, move to the end of the
string. If point is at the beginning of a parenthetical
expression, move to the end of it. If at the beginning of
statement block that is surrounded by braces, move to the
end of the block. If point is at an identifier, skip to the
end of it.

argument</dfn> command. Type <kbd>C-u </kbd><var>n</var>, where <var>n</var> is
the number of times to repeat a command. If no number
<var>n</var> is provided, Emacs will repeat the command 4 times
by default. See <a href="http://emacswiki.org/cgi-bin/info-ref?find=Arguments.html#Arguments">Numeric Arguments</a>.
