Captcha loop

I'm making a script that I would like to wait for me to fill in a Captcha and continue executing. This is probably really simple, but I'm very new to PHP progging. A while() loop perhaps?

while(notfuggindone)
{
wait;
}

I figured out a way to do what I want. I'm just going to put the script in an iframe and decorate the outside with links that I can press when I'm done with the Captcha.
