? & Lt;? Php

namepace adminController;

Use ThinkController;

Use ThinkVerify;

Class Logincontroller Extends Controller ogin () {(if (! Empty ($ _ post)) {

$ $ vry = new Verfiy (); Public function verfiyImage(){

                                                                                                            'imageH' => 45, //Verification code image height

                                                                                                                     100, //Verification code image width

'fontttf' => '2.ttf', //Verification code font

} }

//Instantiate the verify class

                               //Output verification code

$ Very -& gt; entry (); // Output verification code}

The above introduces the use of verification code verification in tp, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
