Here is the code for the output:

    <!DOCTYPE html>

    <script type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>

<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>

Here is the code for processing and returning the values to the index page

//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);
?>

And here is the code for viewing the values of the text file this is just for checking purposes

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

And the output of it is just like this

 array (size=10)
  0 => 
    array (size=2)
      'ASIN' => string 'B005CI62XY' (length=10)

      'Title' => string 'Nike Air Max+ 2012 Mens Running Shoes 487982-100' (length=48)

As what I notice the array stored is only the last 10 items from the index page, What I to happen is that all items from the index page will be save in the text file, I dont how can I fix this, Anyone any advice or suggestion to help me with my problem will be a big help thanks!

Answer 1

Without caring about file locking issues you need to move a few statements around:

// 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));

That's all you need.

Update

Your code performs 11 AJAX requests (for 11 result pages) each calling Amazon to populate the results of each page; this is highly inefficient and you should perform the search only once, find out how many pages there are and then use the Amazon API itself to get all the results in one go.

Doing so will eliminate the need to keep a temporary file in the first place as your search.php can return ALL results to JavaScript in just one call.

Answer 2

我认为你需要在'追加'模式下打开文件。

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

Answer 3

I think your answer might be in the mode you set for "fopen"

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

You can see that the second parameter for this function is the mode. You have it as "w", which means, straight from the docs:

Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

This will overwrite your file every time. You'll most likely want to open the file in "a" (that is, append) mode.

Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.

Answer 4

$fh = fopen('log', 'w'); Change it to $fh = fopen('log', 'a');

w - will remove existing content a- will keep the content and append the new content
