(I think this is supposed to be fixed 'in CVS' whatever that means, but just in case...)

similar_text() requires a parameter by reference but generates a warning for doing so!  My log file is thus packed with warnings as follows, and I must switch off the php.ini setting which warns about such things.

[Mon Apr 28 23:37:25 2003] [error] PHP Warning:  Call-time pass-by-reference has been deprecated - argument passed by value;  If you would like to pass it by reference, modify the declaration of similar_text(). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file.  However, future versions may not support this any longer.  

I am told to "modify the declaration of similar_text()", a PHP function!

I would suggest that if PHP is deprecating pass-by-reference:
- this function be changed ASAP
- this function (and any others) that are part of PHP and use reference variables do not issue a warning
- at the very least, a note in the documentation for similar_text() about this.

It is my aim (and the general aim of good programming I suppose) to log and fix ALL errors, but this one makes this aim impossible unless I switch this error off completely!

Thanks!
