effigy Posted September 8, 2006 Share Posted September 8, 2006 Are the letters [i]always[/i] the first 3 characters? If so, use substr, if not, regex. Link to comment https://forums.phpfreaks.com/topic/20139-splitting-text-and-numbers/#findComment-88538 Share on other sites More sharing options...
robos99 Posted September 8, 2006 Share Posted September 8, 2006 "everytime i want to add a member i want 1 to be added so that it goes: mem0001, mem0002 etc"I know you said you know how to do this, but you do realize that the numbered portion is still going to be a string right? So you can't just say $numbers++ because you can't perform math on a string. I'm sure there's a way to convert data types....but I'm not sure off the top of my head.

Woodburn2006 Posted September 9, 2006 Author Share Posted September 9, 2006 cool thanks, i now have the number, but as you said the numbers are in a string and when i try adding 1 to it, all i get is the value being 1, is there any way i can convert this to a number so that i can do maths with it?

extrovertive Posted September 9, 2006 Share Posted September 9, 2006 How about in your database table, how two fields? ID and memberid? ID will be the auto increment number and memberid will be a string of "member" + ID as a string? Each time you add a member, you take the ID of what was last inserted and then append it to the "member" string then insert it to the memberid field.

kenrbnsn Posted September 9, 2006 Share Posted September 9, 2006 Did you actually try adding 1 to the number part? Adding a number to a number is a string should work correctly. Copy and run this example:[code]<?php$str = "mem0001";$mem = substr($str,0,3);$num = substr($str,3);echo $str . ' => ' . $mem . ',' . $num . '<br>';$num++;echo '$num + 1 = ' . $num;echo '<br>New member number = ' . $mem . sprintf("%04d",$num);?>[/code]Ken Link to comment https://forums.phpfreaks.com/topic/20139-splitting-text-and-numbers/#findComment-89129 Share on other sites More sharing options...
