Is this a bugger of fwrite()?

[Anon]

I have a file: email_from.txt, the content is [e-mail]
other file is : change_email_from.php .the code is :
if($emailFile = fopen("mail_from.txt", "r+"))
{
fwrite($emailFile, $email,strlen($hiddenEmail));
fclose($emailFile);
}

the $email is a Text Box of a Form,the Form's action is "change_email_from.php".After change_email_from.php execute. the content of email_from.txt became [e-mail].
I have try some times,the reult is the same.
Is this a bugger of fwrite()? or my useing is wrong?

Thanks for your help.

Try changing the filename in the script to the filename on the file. 🙂
