Hi all, I am having trouble generating a sequence of numbers from the following start value: AX0001 what I have done so far is loop through each character and check if its a alphabet and separating the characters and digits. But when I increment the digits, its strips of the leading zeros. How can I get a sequence of values like: AX0001 AX0002 AX0003 AX0004 ..... AX0099 AX0100 and so on ? jeffery -- Internet Vision Technologies Level 1, 520 Dorset Road Croydon Victoria - 3136 Australia web: http://www.ivt.com.au phone: +61 3 9723 9399 fax: +61 3 9723 4899 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
