Parse function for PHP. Makes use of the tokenizer from tokenizephp.js.
Based on parsejavascript.js by Marijn Haverbeke.
Features:
+ special "deprecated" style for PHP4 keywords like 'var'
+ support for PHP 5.3 keywords: 'namespace', 'use'
+ 911 predefined constants, 1301 predefined functions, 105 predeclared classes
from a typical PHP installation in a LAMP environment
+ new feature: syntax error flagging, thus enabling strict parsing of:
+ function definitions with explicitly or implicitly typed arguments and default values
+ modifiers (public, static etc.) applied to method and member definitions
+ foreach(array_expression as $key [=> $value]) loops
+ differentiation between single-quoted strings and double-quoted interpolating strings

/**
* Storage and control for undo information within a CodeMirror
* editor. 'Why on earth is such a complicated mess required for
* that?', I hear you ask. The goal, in implementing this, was to make
* the complexity of storing and reverting undo information depend
* only on the size of the edited or restored content, not on the size
* of the whole document. This makes it necessary to use a kind of
* 'diff' system, which, when applied to a DOM tree, causes some
* complexity and hackery.
*
* In short, the editor 'touches' BR elements as it parses them, and
* the UndoHistory stores these. When nothing is touched in commitDelay
* milliseconds, the changes are committed: It goes over all touched
* nodes, throws out the ones that did not change since last commit or
* are no longer in the document, and assembles the rest into zero or
* more 'chains' -- arrays of adjacent lines. Links back to these
* chains are added to the BR nodes, while the chain that previously
* spanned these nodes is added to the undo history. Undoing a change
* means taking such a chain off the undo history, restoring its
* content (text is saved per line) and linking it back into the
* document.
