Analysis of the solution to the Thinkphp,onethink and Thinkox verification code in _php instance

The example in this article describes the workaround for the Thinkphp,onethink and Thinkox validation code not shown. Share to everyone for your reference, specific as follows:

When using the verification code, it starts normal, and then it doesn't show up.

Online said is utf-8 coding problem, what BOM removed, into a no BOM format

I tried, it didn't work.

Later I knew it was written in the place where the captcha was invoked.

Public Function Verify () {
import (' ORG. Util.image ');
Image::buildimageverify ();
}

That would be fine:

Public Function Verify () {
import (' ORG. Util.image ');
Ob_clean ()//This is the key
image::buildimageverify ();
}

Ob_clean This function is used to discard the contents of the output buffer, if your site has a lot of generated picture class files, then want to access the correct, you need to often clear the buffer.
