Question

我有一个上传text.txt文件的表单，其中包含action =“profit-process.php”

在profit-process.php中，我将.txt文件转换为数组：

<?php
$file = "text.txt";// Your Temp Uploaded file
$handle = fopen($file, "r"); // Make all conditions to avoid errors
$read = file_get_contents($file); //read
$lines = explode("\n", $read);//get
foreach($lines as $key => $value){
    $code[] =  $value[0];
    $name[] = $value[1];
    $cost[] = $value[2];
    $selling_price[] = $value[3];
  }
echo "<pre>";
print_r($lines); //explore results
echo "</pre>";
?>

我想要做的是使用表而不是print_r（$ lines）在.txt（进入数组）中显示数据。

所以目标格式是：

<table>
  <tr><th>Code</th><th>Name</th><th>cost</th><th>Selling Price</th></tr>
  <tr><td>1234</td><td>Nike Air</td><td>30.00</td><td>60.00</td></tr>
</table>

将有多行文本文件，因此表中的行数将反映文本文件数据。

任何帮助都非常感激。

干杯

Answer 1

你的最终节目应该是：

注意：首先阅读extract()。

<?php
$file = "text.txt";// Your Temp Uploaded file
$handle = fopen($file, "r"); // Make all conditions to avoid errors
$read = file_get_contents($file); //read
$lines = explode("\n", $read);//get

$arr = array();
foreach($lines as $key => $value){
    $temp = array();
    $temp['code'] =  $value[0];
    $temp['name'] =  $value[1];
    $temp['cost'] =  $value[2];
    $temp['selling_price'] =  $value[3];
  $arr[] = $temp;
 }
echo "<pre>";
print_r($lines); //explore results
echo "</pre>";
?>
<table border="1" align="center">
    <tr>
        <th>Code</th>
        <th>Name</th>
        <th>Cost</th>
        <th>Selling Price</th>
    </tr>
<?php
if (! empty($arr)) {
    foreach ($arr as $elem) {
        extract($elem); // EXTRACT VARIABLES SO THAT, $elem['cost'] becomes $cost, read PHP documentation on extract();
        ?>
        <tr>
            <td><?php echo $code;?></td>
            <td><?php echo $name;?></td>
            <td><?php echo $cost;?></td>
            <td><?php echo $selling_price;?></td>
        </tr>
        <?php
    }
}
?>
</table>

Answer 2

尝试 -

<table>
  <tr><th>Code</th><th>Name</th><th>cost</th><th>Selling Price</th></tr>
  <?php
  foreach($lines as $key => $value) {
  ?>
  <tr><td><?php echo $value[0]?></td><td><?php echo $value[1]?></td><td><?php echo $value[2]?></td><td><?php echo $value[3]?></td></tr>
  <?php
  }
  ?>
</table>

Answer 3

试试这个

<table>
  <tr><th>Code</th><th>Name</th><th>cost</th><th>Selling Price</th></tr>
<?php for($i=0;$i<count($code);$i++):?>
  <tr><td><?php echo $code[$i];?></td>
  <td><?php echo $name[$i];?></td>
<td><?php echo $cost[$i];?></td>
<td><?php echo $selling_price[$i];?></td></tr>
<?php endforeach;?>
</table>
