代碼如下：
cat book.php
  1. <?php
  2. $link = mysql_connect('localhost', 'root', '******') or die('Could not
  3. connect: ' . mysql_error());
  4. mysql_select_db('bookstore') or die('Could not select database');
  5. header("Content-Type: text/xml");
  6. //check for the path elements
  7. if(isset($_SERVER['PATH_INFO'])){
  8.     $path=$_SERVER['PATH_INFO'] ;
  9. }
  10. #$path=isset($_SERVER['PATH_INFO']) ? $_SERVER['PATH_INFO']:'';
  11. #echo($path);
  12. if($path!=null){
  13. #    $path_params=spliti("/",$path);
  14.     $path_params=explode('/',$path);
  15. }
  16. #print_r($path_params);
  17. if($_SERVER['REQUEST_METHOD']=='POST'){
  18.     $input=file_get_contents("php://input");
  19.     $xml=simplexml_load_string($input);
  20.     foreach($xml->book as $book){
  21.         $query="INSERT INTO book (name,author,isbn) VALUES ('$book->name','$book->author','$book->isbn')";
  22.         $result=mysql_query($query) or die('Query failed:' . mysql_error());
  23.         mysql_free_result($result);
  24.     }
  25. }
  26. else if($_SERVER['REQUEST_METHOD']=='GET'){
  27.     if($path_params[1]!=null){
  28.         settype($path_params[1],'integer');
  29.         $query="SELECT b.id, b.name,b.author, b.isbn FROM book as b where b.id=$path_params[1]";
  30.     }else{
  31.         $query='SELECT b.id, b.name,b.author, b.isbn FROM book as b';
  32.     }     
  33.     //Handle GET request, Return the list of books
  34.     //$query='SELECT b.id, b.name,b.author, b.isbn FROM book as b';
  35.     $result=mysql_query($query) or die("Query failed:" . mysql_error());
  36.     #echo "<document>";
  37.     echo "<books>";
  38.     while($line=mysql_fetch_array($result, MYSQL_ASSOC)){
  39.         echo "<book>";
  40.         foreach($line as $key=> $col_value){
  41.             echo "<$key>$col_value</$key>";
  42.         }
  43.         echo "</book>";
  44.     }
  45.     echo "</books>";
  46.     #echo "</document>";
  47.     mysql_free_result($result);
  48. }
  49. mysql_close($link);
  50. ?>
復(fù)制代碼
本來(lái)的design是：我訪問(wèn)
GET http://localhost/php_site/library/book.php  看到所有的書(shū)。
GET http://localhost/php_site/library/book.php/1 能看到id為1 的書(shū)
但是我的這個(gè)代碼現(xiàn)在變成了：
我必須要訪問(wèn)
GET http://localhost/php_site/library/book.php/ 才能看到所有的書(shū)。奇怪。
如果我GET http://localhost/php_site/library/book.php 就會(huì)報(bào) " undefined path "
