php 4.0.2 and args in a function

All - I noticed some 'new behavior' with the release of php 4.0.2 and I'm not sure if it's intended behavior or if it's just my coding style. Here's a small sample script I wrote to demo the problem: 00 <? 01 function smoosh($var1, $var2) { 02 return $var1 . $var2; 03 } 04 ?> 05 <HTML> 06 <BODY> 07 <? 09 $onevar = smoosh("string1a","string2a"); 10 print("<P>".$onevar); 11 $twovar = smoosh("string1b"); 12 print("<P>".$twovar); 13 ?> 14 </BODY> 15 </HTML> And the output: 00 string1astring2a 01 Warning: Missing argument 2 for smoosh() in /home/httpd/html/testpage.html on line 2 03 04 string1b If I pass my sample function only one of the two vars it expects I generate the error shown on line 01 of my output. Under version 4.0.0 and prior I did not see this behavior. The 4.0.2 version of php I used came from the Red Hat 7.0 beta. I used the src.rpm file to rebuild the packages on my Red Hat 6.2 box and installed them with rpm. The install was smooth and aside from having to tweak the rpm spec file a bit to account for the differences between 7.0 and 6.2 no major errors occurred. Is there a specific php option I should check for that would generate these type of warnings? Thanks for the help. -- Scott
