problems with php 4.1.1 (strtok?)

Hi, I have a script to upload/insert records in a mysql db. I was running fine before the upgrade (php 4.0.4pl1) now it confuses the columns starting with the column number 9. I've attached a one line file that I used with the scripts. the problem seems to be with strok and null values. One of the columns is empty so I have value1\t\tvalue2 and it seems to confuse itself. The script that parses the line is like this $C_F=strtok($line,"\t"); $dt=strtok("\t"); $DT=strtok("\t"); Using the same script under php4.0.6 with the same upload file it shows (correct) : insert into table values values('05','01/11/01','10:01','MYCOMPANY','04.679.080/0001-04','OTHERCOMPANY','SP-SAO PAULO','47.427.653/0014-30','109726','02','091330','15','VOL','PROD','383,1000','10075/01','EQT-0001','EQT-0001','','','','','','','','','01/11/01','08:00','01/11/01','18:00','09/11/01','08:00','09/11/01','08:00','','7D,22H','') Using the same script under php4.1.1 with the same upload file it shows (incorrect 02 at column number 9) : insert into cargas values values('05','01/11/01','10:01','MYCOMPANY','04.679.080/0001-04','OTHERCOMPANY','SP-SAO PAULO','47.427.653/0014-30','02','091330','15','VOL','PROD','383,1000','10075/01','EQT-0001','EQT-0001','01/11/01','08:00','01/11/01','18:00','09/11/01','08:00','09/11/01','08:00','7D,22H','050210972604.679.080/0001-0447.427.653/0014-30091330','/ /','','','','','','','','','109726') Thanks. __________________________________________________ Do You Yahoo!?
