这就是这种情况。我有一个程序从数组中获取数据并将其显示在表格上。我创建了允许客户端输入新项目的文本输入类型，当单击提交按钮时，所有字段都将添加到表中。我在想是否有办法将数组写入文本文件并执行 fwrite 将客户端输入写入文本文件。我还注意到文本文件不断被覆盖，因此输入的数据不会保留，而不是

$handle=fopen($myfile, "w");

我应该使用

$handle=fopen($myfile, "a");

如果不存在文件，是否会修改工作，如果不存在，它将创建文本？

当我运行部分借用和创建的代码时，客户端新表不会添加到已经存在的表中。

抱歉，如果不清楚，我是新手。任何帮助将不胜感激，如果您需要更多信息，请告诉我。

这是我到目前为止开发的代码：

            if(!empty($_POST['product_name']))
            {

如果您必须使用文本文件而不是数据库，那么最好的方法是将表格行数据附加到CSV格式的文件中。

脚本的第一部分应处理表单输入，最好验证每个字段，但以最简单的形式，您可以从 POST 数据创建一个数组。然后您可以使用fputcsv()写入文件，并使用 fgetcsv() 将 CSV 数据放入一个数组中，以便您可以在表格中显示它。

<?php

/**
 * Ensure you have the full path to the file on the file system
 */
$myFile = dirname(__FILE__).DIRECTORY_SEPARATOR.'file.txt';

/**
 * This section handles the form submit
 */

// Create a boolean value checking the necessary data is posted
$check = isset(
  $_POST['product_name'],
  $_POST['product_description'],
  $_POST['price'],
  $_POST['image']
);
// Do we have the data?
if ($check) {

  // Open the file to append a new row
  $fh = fopen($myFile, "a");

  // Create an array of data from the POSTed vars
  $dataRow = array(
    $_POST['product_name'],
    $_POST['product_description'],
    $_POST['price'],
    $_POST['image']
  );

  // Write the data to file in CSV
  fputcsv($fh, $dataRow);

  // Close the file
  fclose($fh);

}

/**
 * Then we re-open the file for reading
 */
$fh = fopen($myFile, "r");

/**
 * The next section displays the table
 */
?>
  <!DOCTYPE html>
  <html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

  <body>

  <form action="/" method="post">
    <p>
      <label for="product_name">Product Name</label>
      <input id="product_name" name="product_name" type="text"/>
    </p>
    <p>
      <label for="product_description">Product Description</label>
      <input id="product_description" name="product_description" type="text"/>
    </p>
    <p>
      <label for="price">Price</label>
      <input id="price" name="price" type="text"/>

    <p>
      <label for="image">Image</label>
      <input id="image" name="image" type="text"/>
    </p>
    <input type="submit" value="Submit"/>
  </form>

  <table border="1" align="center" cellpadding="10">
    <tbody>
    <thead>
    <tr>
      <th>Product Name</th>

    <tbody>
    <?php
    /**
     * Here you can loop through each row in the file, getting an array of
     * data from the CSV values
     */
    $data = fgetcsv($fh);

    ?>
    <?php while (($data = fgetcsv($fh)) !== false) : ?>
      <tr>
        <td><?php echo htmlentities($data[0]); ?></td>
        <td><?php echo htmlentities($data[1]); ?></td>
        <td><?php echo htmlentities($data[2]); ?></td>
        <td><?php echo htmlentities($data[3]); ?></td>
      </tr>
    <?php endwhile; ?>
    </tbody>
    </tbody>
  </table>
