i'm building web application , i'm concern security. is way make "php injection", in same way possible make "sql injection" ? means client can send php code executed on server. until don't use "eval" function, "no" because when value $_get , $_post, data treated simple string... maybe don't see obvious attack. in general, not unless evaluate might parse , execute php. mentioned eval, there other functions have eval-like properties (e.g. preg_replace , if attacker manages inject /e modifier) or can otherwise allow unwanted levels of access (e.g. system() ). also, if attacker can upload file , interpreted php, can run php code. nginx can easily misconfigured in way allows attackers execute php code in image files. same goes getting web site include() code - possibly overwriting files uploads, or changing include() arguments point remote site (if not disabled in php.ini).

is there python 2.7 package contains gauss-siedel solver systems more 3 linear algebraic equations containing more 3 unknowns? simple example of sort of problem solve given below. if there no templates or packages available, possible solve in python? if please advise on best way of going it. thanks. an example of 3 linear algebraic equations 3 unknowns (x,y,z): x - 3y + z = 10 2x + 5y + z = 4 -x + y - 2z = -13 after bit of searching around found solution use numpy.linalg.solve command. command uses lapack gesv routine solve problem; not sure iterative technique uses. here code solve problem if interested: a = np.array([[1,-3,1],[2,5,1],[-1,1,-2]]) b = np.array([10,4,-13]) x = np.linalg.solve(a, b) print x print np.allclose(np.dot(a, x), b) # check solution found
