อันนี้เป็น code ไฟล์ amazonv4.php บางส่วนครับ ที่ include aws_signed_request.php
Code (PHP)

<?php
//amazonv4.php
//stand-alone PHP example script to use the Amazon Web Services interface
//20020816/JvG, released under the GNU GPL
//20030203/JvG, adapted for the heavy version
//20030630/JvG, adapted further
//20030717/JvG, expanded further, this will be released as amazonh3.php
//20030912/JvG, fixed the 'register global' issue that a lot of people had trouble with
//20030912/JvG, found an excessive ' that caused trouble remembering the product category
//20030912/JvG, turned $pagefr0 back into $page (so base 1 instead of base 0, makes script clearer)
//20030912/JvG, tried to explain the associate ID issue better
//20030912/JvG, in case of the UK locale I show the USA product categories, which looks slightly better
//20030912/JvG, in data.php I have disabled Japan, because the script can't really support it
//20030912/JvG, in language.php I fixed a spelling mistake in 'buecher USA'
//20031125/JvG, commented out the hidden language and locale fields in the form
//20040129/Ted Knudson remarked that looking for things like 'kitchen design' didn't work properly and so I added urlencode() at three places in the script
//20040202/Tatiana Vygurska found some errors:
//20040202/JvG, turned $pagefr0 back to $page in the link to the previous page
//20040202/JvG, declared $locale global in function printProduct()!
//20040408/JvG, removed the v=2.1 parameter
//20040715/JvG, added some suggestions by Wim Roffel
//20041207/JvG, utf8_decode() is now executed before interpreting the XML as someone suggested
//20041219/JvG, added a couple of lines of code to print the time used to get data from Amazon and handling it
//20050118/JvG, tried if the script would also easily work with version 4
//20090623/JvG, busy adding the signing that Amazon requires from 20090815
//20090804/JvG, refixed the do/du problem for used products (which had gone after going back to an old version) and added the (server) locale functionality to the signed version
//20090804/JvG, rewrote the scripts to make the new version (with signing) more like the old version so that the caching would work again but didn't test it yet, this also made show_url work again
//20090812/JvG, added the comments for 20090804 and 20090812 and tested the caching and I am going to try to put the script online
//20090816/JvG, always use signed request, started adding better time measurement
 
//Thanks for all the questions, improvement tips and help!
//Feel free to send more feedback to me at ganswijk@xs4all.nl!
//Please mention Amazon in the subject line to avoid my spamfilters

ไม่รู้ว่าแก้ได้หรือยัง
ปัญหานี้คือมีการเรียกไฟล์ที่ประกาศฟังก์ชั่นซ้ำซ้อนเลยทำให้เกิด error

วิธีแก้คงต้องไล่สเต็ปละครับว่าไฟล์ไหนที่เป้นปัญหา

หรือถ้าจะแก้แบบลวก ๆ อาจจะใช้

if(!function_exists("aws_signed_request")) {
function aws_signed_request($region, $params, $public_key, $private_key){
ฟังก์ชั่น aws_signed_request ทั้งหมด..............
}
}

ไม่แน่ใจว่าจะ "เอาอยู่" หรือเปล่า

พอดีผมเจออีกปัญหา เจอเป็นบางครั้งเลยค้น google มาเจอกระทู้นี้

Warning: simplexml_load_string() [function.simplexml-load-string]: Entity: line 1: parser error : expected '>' in aws_signed_request.php

ไม่แน่ใจว่า amz มีการเปลี่ยนแปลงโครงสร้าง xml ที่ return กลับมาหรือยังไง
แต่บางครั้งก็ผ่าน บางครั้งก็ติด

ใครเจอปัญหานี้ช่วยแนะนำที

ขอบคุณอย่างสูงยิ่ง
