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
    -j, --json-dump         Print json_encode() result
        --var-dump          var_dump() nodes (for exact structure)
    -N, --resolve-names     Resolve names using NodeVisitor\NameResolver
    -c, --with-column-info  Show column-numbers for errors (if available)
    -P, --with-positions    Show positions in node dumps
    -r, --with-recovery     Use parsing with error recovery
        --version=VERSION   Target specific PHP version (default: newest)
    -h, --help              Display this page

Example:
    php-parse -d -p -N -d file.php

    Dumps nodes, pretty prints them, then resolves names and dumps them again.
