comapring two variables of strings

[shror]

hi,

i am building a small mail form system that i want to make it safe as
much as i can, so i added a ramdomly generated 4 characters that my
user have to enter in the corresponding text box so that if he entered
these characters correct the mail is sent if not the error message
appear.

what i have:
1- i used a randomly generated 4 characters
2- text bex for the user to enter the randomly generated variables
3- if else statement:

my if...else code

if ($UserEnteredText == $RandomText){
echo "correct";
}
else{
echo "wrong";
}
my problem:
always the code echos wrong message, which means that i have a problem
that i dont know what is it.

so please help me
I really need your help ASAP

Thanks in advance

What's in $UserEnteredText and $RandomText when you make the test? Echo
them to the window to find out.

At a guess, the receiving script regenerates a new value for $RandomText,
rendering the text that the user entered, based on the previous random
text, incorrect.

If you feel you really *must* do this, then take a look at the
Text_CAPTCHA module in PEAR instead of re-inventing the wheel.

But be aware that CAPTCHA techniques are usually inaccessible to at least
one portion of society, often blind people. This can make their use in
some countries illegal under disability discrimination legislation.

my idea is that when the mail form is loaded the randomly generated
characters are also loaded and echoed and the user will only have to
enter the echoed characters so that my system knows if its a human or
not who is using the form

someting for spam protection of my self and my users

It would take maybe 10 minutes to write a robot that could defeat that.
Use Text_CAPTCHA.

my problem is that i dont know how to write robot and i dont know how
robot works to write it, so i decided to do something like what yahoo,
google, hotmail and all website do now which is telling you to enter
the characters in the image correctly, i think that this is some sort
of security, isn't it

so all what i want to do is check two variables carrying string of
characters if they are identical or not and i dont know how to check
them, i tried but i got wrong outputs, so i need your help please.

Thanks

Shror,

You don't need to know how to write a robot - the key here is SOMEONE
ELSE does. And it can be done very quickly, as Toby pointed out.

Did you try my suggestion of echoing both values to the screen instead
of doing a compare? See what they say?

Also - do you have all errors enabled?

Did you follow Toby's suggestion to search on CAPTCHA? There are a lot
of ready-made packages out there.

Instead of arguing with everyone, why not try some of the suggestions?
