由于我注意到存储的数组只是索引页中的最后10个项目，因此我要做的是，索引页中的所有项目都将保存在文本文件中，我不知道如何解决此问题，任何人对我的问题有任何建议或建议都将是很大的帮助谢谢

我认为您需要以“附加”模式打开文件

$fh = fopen('log', 'a');
我想你的答案可能是你为“fopen”设置的模式

您可以看到此函数的第二个参数是mode。您将其命名为“w”，这意味着，直接从文档中可以看出：

只供写作使用；将文件指针放在文件的开头，并将文件截断为零长度。如果文件不存在，请尝试创建它

这将每次覆盖您的文件。您很可能希望以“a”（即追加）模式打开该文件

只供写作使用；将文件指针放在文件末尾。如果文件不存在，请尝试创建它。

$fh=fopen（'log'，'w'）将其更改为
$fh=fopen（'log'，'a'）

w-将删除现有内容

a-将保留内容并附加新内容
，而不考虑文件锁定问题您需要移动一些语句：


// 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));



//删除了fopen（），因为file\u get\u contents（）已经为您打开了该文件
$array\u item=unserialize（文件获取内容（'log'）；
//在这里操纵数组
foreach（$response->Items->Items as$Item）{
$array\u item[]=array（'ASIN'=>$item->ASIN，'Title'=>$item->itemtattributes->Title）；
回显“.$item->ASIN.”.$item->itemtattributes->Title.”；
}
文件内容（'log'，序列化（$array\u item））；


这就是你所需要的

更新

您的代码执行11个AJAX请求（11个结果页面），每个请求调用Amazon来填充每个页面的结果；这是非常低效的，您应该只执行一次搜索，找出有多少页，然后使用AmazonAPI本身一次性获得所有结果


这样做将首先消除保留临时文件的需要，因为您的
search.php
可以在一次调用中将所有结果返回到JavaScript。
文件内容是一个序列化数组，因此，简单地附加到文件将破坏它。@GrayFullBuster另一种选择是先读取文件并将其存储在数组中，然后将新数据附加到此数组中，然后再将其写入文件。关于这行代码“文件内容（'log'，序列化（$array_item））；”高于写入还是低于写入？@GrayFullBuster您不需要任何
fopen（）
或
fwrite（）
；我的代码基本上就是你所需要的；当您需要文件锁定时，事情会变得更加棘手，但是既然您已经提到了它只是用于测试…这行代码“”只是用于测试，以了解是否已经包含数据，而其他代码不用于测试。什么是文件锁定？谢谢@GrayFullBuster由于该文件不断增长，您最终会耗尽内存，所以您可能需要的是一个数据库？与Harmeet的答案相同；该文件包含一个数组的序列化表示形式，如果你简单地附加到它，它将被破坏！

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



// 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));
