這是輸出的代碼：

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>Tester</title>
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
</head>
<body>
<?php

$search = 'Nike';
$temp_search = $search;
$category = 'Shoes';
$flag = 0;
$page = 11;
$temp = '';

for($i=1;$i<=$page;$i++){
?>
<script type="text/javascript">
    $(function(){
        $.ajax({
            url: 'search.php',
            type: 'post',
            datatype: 'json',
            data: { search: '<?php echo $search; ?>', category: '<?php echo $category; ?>', page: '<?php echo $i; ?>' },
            success:function(data){
                $('#data').append(data);
            }
        });
    });
</script>
<?php
    if($i == 10){
        $i = 1;
        $flag++;
        $search = $temp_search.' '.$flag;
    }
    if($flag == 1){
        break;
    }
}
?>
<table id="data">

</table>

</body>
</html>

以下是處理值並將值返回到索引頁面的代碼

//search.php
    <?php

include 'Amazon-ECS-PHP-Library-master/samples/sampleSettings.php';
require 'Amazon-ECS-PHP-Library-master/lib/AmazonECS.class.php';

$amazonEcs = new AmazonECS(AWS_API_KEY, AWS_API_SECRET_KEY, 'com', AWS_ASSOCIATE_TAG);
$amazonEcs->requestDelay(true);
$amazonEcs->associateTag(AWS_ASSOCIATE_TAG);

$response = $amazonEcs->responseGroup('Large')->category('Shoes')->page($_POST['page'])->search($_POST['search']);
$fh = fopen('log', 'w');
$array_item = unserialize(file_get_contents('log'));
foreach($response->Items->Item as $item){
    $array_item[] = array('ASIN'=>$item->ASIN, 'Title'=>$item->ItemAttributes->Title);
    echo '<tr><td>'.$item->ASIN.'</td><td>'.$item->ItemAttributes->Title.'</td></tr>';
}
fwrite($fh, serialize($array_item));
fclose($fh);
?>

以下是用於查看文本文件值的代碼，這僅用於檢查目的

 <?php
var_dump(unserialize(file_get_contents('log')));
?>

它的輸出就是這樣的

 array (size=10)
  0 => 
    array (size=2)
      'ASIN' => string 'B005CI62XY' (length=10)
      'Title' => string 'Nike Men's Performance Moisture Wicking No Show Socks 6 Pair - Shoe Size: 8-12 - White' (length=86)

正如我注意到存儲的數組只是索引頁面中的最后10個項目，我要做的是索引頁面中的所有項目都將保存在文本文件中，我不知道如何解決這個問題，任何建議或者建議幫助我解決我的問題將是一個很大的幫助謝謝！

Answer 1

如果不關心文件鎖定問題，您需要移動一些語句：

// removed the fopen() because file_get_contents() already opens the file for you
$array_item = unserialize(file_get_contents('log'));

// manipulate the array here
foreach($response->Items->Item as $item){
    $array_item[] = array('ASIN'=>$item->ASIN, 'Title'=>$item->ItemAttributes->Title);
    echo '<tr><td>'.$item->ASIN.'</td><td>'.$item->ItemAttributes->Title.'</td></tr>';
}

file_put_contents('log', serialize($array_item));

這就是你所需要的。

更新

您的代碼執行11個AJAX請求（對於11個結果頁面），每個請求都調用Amazon來填充每個頁面的結果; 這是非常低效的，您應該只執行一次搜索，找出有多少頁面，然后使用Amazon API本身一次性獲得所有結果。

這樣做將消除首先保留臨時文件的需要，因為search.php可以在一次調用search.php所有結果返回給JavaScript。

Answer 2

我認為你需要在'追加'模式下打開文件。

$fh = fopen('log', 'a');

Answer 3

我想你的回答可能是你為“fopen”設置的模式

http://us3.php.net/manual/en/function.fopen.php

您可以看到此功能的第二個參數是模式。 你把它作為“w”，這意味着，直接來自文檔：

僅供寫作; 將文件指針放在文件的開頭，並將文件截斷為零長度。 如果該文件不存在，請嘗試創建它。

這將每次覆蓋您的文件。 您很可能希望以“a”（即追加）模式打開文件。

僅供寫作; 將文件指針放在文件的末尾。 如果該文件不存在，請嘗試創建它。

Answer 4

$fh = fopen('log', 'w'); 將其更改為$fh = fopen('log', 'a');

w - 將刪除現有內容a-將保留內容並附加新內容
