PHP 高级 HTMLDOM 错误
PHP Advanced HTMLDOM error
我让 php AdvancedHTMLDOM 长时间正常工作。然而,大约一周前,我注意到我正在抓取的数据由于某种原因没有更新。
我手动 运行 脚本并得到以下错误:
root@telemetry:/home/telemetry/scripts/pressure# php -f get_pressure_nodes.php
PHP Fatal error: Uncaught Error: Class 'DOMDocument' not found in /home/telemetry/scripts/pressure/advanced_html_dom-master/advanced_html_dom.php:171
Stack trace:

这是我的脚本(为了简单起见,我保留了基础知识,而且我从某个我不记得的地方得到了这段代码,所以如果是你的,请通知我,这样我就可以在它到期的地方给予信任):
<?php
require('advanced_html_dom-master/advanced_html_dom.php');
$html = file_get_html('get_pressure_nodes.html');
$table = $html->find('table', 1);
$rowData = array();
foreach($table->find('tr') as $row)
{
// initialize array to store the cell data from each row
$temp = array();
foreach($row->find('td') as $cell)
{
// push the cell's text to the array
$temp[] = $cell->plaintext;
}
$rowData[] = $temp;
}
foreach ( $rowData as $cell_contents )
{
print ( $cell_contents ) ;
}
?>
如果 AdvancedHTMLDOM 突然停止工作, 可能有助于修复它。
