PHP: query all variables defined inside function scope -

-

this out of curiosity, wondering if there way query variables defined inside scope of function (exclusively within scope, , within function) , put them in associative array. extended get_defined_vars function.

the reason nice able save 'state' of execution @ point in program, instance debug, log, handle exceptions, or pass entire scope of function one. if i'm not mistaken, think get_object_vars allows doing objects.

from comments of php.net

// top of php script $vars = get_defined_vars();  // stuff $foo = 'foo'; $bar = 'bar';  // variables defined in current scope $vars = array_diff(get_defined_vars(),$vars);  echo '<pre>'; print_r($vars); echo '</pre>';

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
