and enter a description

The system exclaim:
preg_match() [<a href='function.preg-match'>function.preg-match</a>]: 
Compilation failed: missing ) at offset 19 

C:\Program 
Files\Zend\Apache2\htdocs\fovis\protected\modules\rights\components\RAuthorizer.

me too.

My development environment is windows, it runs very well.
But when I deployed my application to my server(which os is centos), I met the 
same error. "preg_match() [<a 
href='function.preg-match'>function.preg-match</a>]: Compilation failed: 
missing terminating ] for character class at offset 30 "

the stack trace is shown in the attached file.

It seems that the error is caused by the data parameter. In RightModule.php, 
the enableBizRuleData attribute is set to false, so in the update form the data 
input doesn't display.  Is that the reason?

eng - when using the Zend, the function  preg_match('/'.$f.'\ *\({1}/', $code)  
  passed names like uer1qc[<lm*ujhb0
which is why the error occurs.
you must either exclude such functions from scanning, or escape special 
characters using the preg_quote.

foreach( $functions as $f ) 
    if( preg_match('/'.preg_quote($f).'\ *\({1}/', $code)>0 )
        return null; // Function call found, not safe for eval.

rus - это потому что Вы используете Zend и он 
создает функции с именами в виде 
кракозяблов. При подстановке в preg_match их 
имен возникает ошибка. Чтобы этого 
избежать, необходимо экранировать эти 
названия с помощью preg_quote($f, "/")

I was still having error, even after make the changes proposed by vasilyev.
If you have the same situation, try to add a delimiter to  preg_quote:

Before:
if( preg_match('/'.preg_quote($f).'\ *\({1}/', $code)>0 )

After:
if( preg_match('/'.preg_quote($f, '/').'\ *\({1}/', $code)>0 )

Now I have no more errors.
