<<<OUTPUT
Usage: php-parse [operations] file1.php [file2.php ...]
or: php-parse [operations] "<?php code"
Turn PHP source code into an abstract syntax tree.
Operations is a list of the following options (--dump by default):
-d, --dump Dump nodes using NodeDumper
-p, --pretty-print Pretty print file using PrettyPrinter\Standard
--serialize-xml Serialize nodes using Serializer\XML
--var-dump var_dump() nodes (for exact structure)
-N, --resolve-names Resolve names using NodeVisitor\NameResolver
Example:
php-parse -d -p -N -d file.php
Dumps nodes, pretty prints them, then resolves names and dumps them again.
