Reproduce code: --------------- <!-- Example 2 from http://us2.php.net/sscanf --> <html><body> <?php // get author info and generate DocBook entry $auth = "24\tLewis Carroll"; $n = sscanf($auth, "%d\t%s %s", &$id, &$first, &$last); echo "<author id='$id'> <firstname>$first</firstname> <surname>$last</surname> </author>\n"; ?> </body></html> Expected result: ---------------- I expected the example from the documentation to work. Actual result: -------------- 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 sscanf(). 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. in c:\inetpub\www\xxx\testsscanf.php on line 5 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 sscanf().
