为了构建这个列表，我使用了两个来源。红字和老鼠的研究。我也加入了一些我自己的想法，在这条线上的人也提供了帮助。
编辑:在发布了这个列表之后，我联系了RIPS的创始人，到目前为止，这个工具会搜索PHP代码来使用这个列表中的每个函数。
这些函数调用大多被分类为sink。当一个受污染的变量(如$_REQUEST)被传递给接收器函数时，就有一个漏洞。RATS和RIPS等程序使用类似grep的功能来识别应用程序中的所有接收器。这意味着程序员在使用这些函数时应该格外小心，但如果它们都被禁止了，那么你就不能完成很多工作。

命令执行
exec - Returns last line of commands output
passthru - Passes commands output directly to the browser
system - Passes commands output directly to the browser and returns last line
shell_exec - Returns commands output
`` (backticks) - Same as shell_exec()
popen - Opens read or write pipe to process of a command
proc_open - Similar to popen() but greater degree of control
pcntl_exec - Executes a program
PHP代码执行
除了eval，还有其他方法来执行PHP代码:include/require可以以本地文件包含和远程文件包含漏洞的形式用于远程代码执行。
eval()
assert() - identical to eval()
preg_replace('/.*/e',...) - /e does an eval() on the match
create_function()
include()
include_once()
require()
require_once()
$_GET['func_name']($_GET['argument']);
$func = new ReflectionFunction($_GET['func_name']); $func->invoke(); or $func->invokeArgs(array());
接受回调的函数列表
这些函数接受一个字符串参数，可以用来调用攻击者选择的函数。根据函数的不同，攻击者可能有也可能没有传递参数的能力。在这种情况下，可以使用像phpinfo()这样的信息披露函数。
Function => Position of callback arguments
'ob_start' => 0,
'array_diff_uassoc' => -1,
'array_diff_ukey' => -1,

'set_error_handler' => 0,

'session_set_save_handler' => array(0, 1, 2, 3, 4, 5),
'sqlite_create_aggregate' => array(2, 3),
'sqlite_create_function' => 2,
信息披露
这些函数调用大多数都不是接收器。但是，如果攻击者可以看到返回的任何数据，那么它可能是一个漏洞。如果攻击者可以看到phpinfo()，这肯定是一个漏洞。

其他
extract - Opens the door for register_globals attacks (see study in scarlet).
parse_str - works like extract if only one argument is given.
putenv
ini_set
mail - has CRLF injection in the 3rd parameter, opens the door for spam.
header - on old systems CRLF injection could be used for xss or other purposes, now it is still a problem if they do a header("location: ..."); and they do not die();. The script keeps executing after a call to header(), and will still print output normally. This is nasty if you are trying to protect an administrative area.

文件系统函数
According to RATS all filesystem functions in php are nasty. Some of these don't seem very useful to the attacker. Others are more useful than you might think. For instance if allow_url_fopen=On then a url can be used as a file path, so a call to copy($_GET['s'], $_GET['d']); can be used to upload a PHP script anywhere on the system.
Also if a site is vulnerable to a request send via GET everyone of those file system functions can be abused to channel and attack to another host through your server.
