我想格式化以下php脚本输出的内容:
<?php
$stop = $_POST["stop_number"]; // stop_number is an text input value provided by user
$depart_url = "http://64.28.34.43/hiwire?.a=iNextBusResults&StopId=" . $stop;
$html = file_get_contents($depart_url);
$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$my_xpath_query = "//td[@valign='top']";
$result = $xpath->query($my_xpath_query);
foreach($result as $result_object)
{
echo $result_object->childNodes->item(0)->nodeValue,'<br>';
}
?>
这是输出(至少在一个实例中,随着时间的推移,数据会发生变化)。
18 - GOLD
OUTBOUND
8:17p
8:16p
8 - GREEN
OUTBOUND
8:46p
8:46p
8 - GREEN
OUTBOUND
18 - GOLD
OUTBOUND
5 - PLUM
OUTBOUND
编辑:
我希望上面的输出信息放在如下表中。但是,不是标签之间的文本,而是来自php脚本输出的变量或项目。
<!DOCTYPE html>
<html>
<title>Departure Table</title>
<body>
<h4>Next Departures for Stop Number: __ </h4>
<table border="1px solid black">
<tr>
<th>Route</th>
<th>Direction</th>
<th>Scheduled</th>
<th>Estimated</th>
</tr>
<tr>
<td>18 - Gold</td>
<td>Outbound</td>
<td>8:17p</td>
<td>8:16p</td>
</tr>
<tr>
<td>8 - Green</td>
<td>Outbound</td>
<td>8:46p</td>
<td>8:46p</td>
</tr>
</table>
</body>
</html>

尝试在echo语句后添加\ n标记:
echo $result_object->childNodes->item(0)->nodeValue."\n";

如果要将数据存储在PHP变量中,可以执行以下操作:
将数据存储在数组中,如变量(或根据您的需要的任何其他数据结构),并迭代变量。
$store_data_in_array_variable = array();
foreach($result as $result_object)
{
$store_data_in_array_variable[] = $result_object->childNodes->item(0)->nodeValue;
}
//iterate over all stored values
foreach ($store_data_in_array_variable as $key => $value)
{
echo $key;
echo '<br>';
echo $value;
}
