Question

在我的网站上，我展示了一些品牌和型号的产品。该数据通过PHP保存在网页上。例如：

<?php
    $producttype1 = array("01" => array("id"=>"01", "brand" => "ABC", "model" => "Hello"),
                         "02" => array("id"=>"02", "brand" => "ABC", "model" => "Hello"),
                         "03" => array("id"=>"03", "brand" => "ABC", "model" => "Hello"),
                         "04" => array("id"=>"04", "brand" => "ABC", "model" => "Hello"),
                         "05" => array("id"=>"05", "brand" => "ABC", "model" => "Hello"));
?>

这些产品由以下代码显示：

<?php foreach($producttype1 as $z)
                { 
            ?>
            <a href="productdetail.php?type=producttype1&id=<?php echo $z["id"]; ?>&brand=<?php echo $z["brand"]; ?>&model=<?php echo $z["brand"]; ?>">
            <div class="product_box">
            <h3><?php echo $z["brand"]; ?></h3>
            <div class="image_box">
            <img src="images/producttype1/<?php echo $z["id"]; ?>.jpg" alt="" />
            </div>
            <p><?php echo $z["brand"]; echo " "; echo $z["model"]; ?></p>
            </div></a>
            <?php
                }
            ?>

我想通过名为products.txt的文件访问此数据，因此数据不会保存在网页上。我有办法吗？

Answer 1

尝试：

$fp = fopen("products.txt", "w");
fwrite($fp, print_r($producttype1, true));

这会将products数组写入文本文件。

Answer 2

$toBeWritten = $producttype1;

$fp = fopen("location/of/the/file/to/write.txt","a"); //replace file path as appropriate
fwrite($fp, serialize($toBeWritten)); // Serialization is easiest
fclose($fp);

请注意，序列化可以反转，阵列可以再次使用。注意：不要使用相同的文件来存储多个数组/对象/等。因为他们会变得腐败。要unserialize再次使用：

$fileContents = '';
$fp = fopen("location/of/the/file/to/write.txt", "r");
$while !(feof($fp)) {
  $fileContents .= fread($fp, 1024);
}
fclose($fp);
$productstype1 = unserialize($fileContents);

php数据从网站分离文件
