result

 not equal 

php script

 public function birth() {      echo "ok"; } 

am using codeigniter 2.0.1, if helps.

thanx in advance.. cheers

lets absolutely clear this. if following appending "not equal":

    string x = "ok";     if (result.equals(x)) {        this.append("equal strings");      } else{        this.append("not equal");      } 

it because result not equal "ok". there can no doubt this.

i suspect 1 of following:

• there leading or trailing whitespace on result string; i.e. space, tab or cr or nl character can't see when output string console.

• possibly, first character 0 ('0') character instead of capital oh ('o').

• possibly, case different.

one way bottom of take 2 strings apart , compare them character character; e.g.

string s = "ok"; if (result.equals(x)) {     this.append("equal strings");  } else if (x.length() != result.length()) {     this.append("lengths different"); } else if (x.charat(0) != result.charat(0)) {     this.append("character 0 different"); } else if (x.charat(1) != result.charat(1)) {     this.append("character 1 different"); } else {     this.append("the universe being swallowed giant squid"); }
