G'Day All,
I've been trying to achieve a way of creating/accessing unique id codes
using a XML document (so it can also be accessed by XSLT) & PHP:
Something like this:
id_list.xml
--------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<id_list>
<id>00001</id>
<id>00002</id>
<id>00003</id>
<id>00004</id>
<id>00005</id>
<id>00006</id>
</id_list>
--------------------------------------------------------
PHP concept
--------------------------------------------------------
1) Load file
- id_list.xml
2) Read file
- id_list.xml
3) Search file for last 20 characters
- 00006</id></id_list>
4) Select first 5 characters (of last 20 from file) & convert to integer
- 00006
5) Add 1 to integer
- 00007
6) Replace the end element with the new integer value (within element <id>)
+ new end string.
- </id_list> = <id>00007</id>
</id_list>
7) Close file
- id_list.xml
--------------------------------------------------------
I've worked out how to do some of these, but I'm having problems with steps
3 & 4.
Any suggestions?
Thanks,
