Display semi-pseudo code in LaTeX

How do I type this within LaTeX using lstlisting, or perhaps some other formatting package?

E_{T}= \phi ;
sort the edges by their weight, $w(e_1) \le w(e_2) \le \dots \le w(e_m))$;
for (i = 1; i \le m; i = i＋1) {
  if ($T+e_i$ contains no cycles) {
    E_T =E_T+ e_i;
  }

Since it looks like pseudo-code, I recommend the algorithmicx package.
