**phutil_symbols.php** [__options__] __path.php__
|

Identify the symbols (clases, functions and interfaces) in a PHP
|
||||
source file. Symbols are divided into "have" symbols (symbols the file
|
||||
declares) and "need" symbols (symbols the file depends on). For example,
|
||||
class declarations are "have" symbols, while object instantiations
|
||||
with "new X()" are "need" symbols.
|
||||
|
||||
Dependencies on builtins and symbols marked '@phutil-external-symbol'
|
||||
in docblocks are omitted without __--all__.
|
||||
|
||||
Symbols are reported in JSON on stdout.
|
||||
|
||||
This script is used internally by libphutil/arcanist to build maps of
|
||||
library symbols.
|
||||
|
||||
It would be nice to eventually implement this as a C++ xhpast binary,
|
||||
as it's relatively stable and performance is currently awful

||||
(500ms+ for moderately large files).
