Php 从页面中提取数据

您好，我想创建一个html和php页面，该页面能够获取此链接中包含的表中的数据：

---

我想知道一些提示，我会使用文件内容，但我不知道如何获取所有的各种数据

这些问题也可能对您有所帮助：

---

您能更清楚地向我们解释一下您想从本页中获得什么吗

无论如何，要做到这一点，您可以使用file\u get\u contents来获取页面，然后根据您想要从页面获取的内容（我假设您想要从表中的页面获取每个

元素），您可以使用来获取所需的所有数据

您的案例示例：

$page = file_get_contents("http://www.comuni-italiani.it/province.html");

$output = array();
preg_match_all('/<td.*.<\/td>/',$page,$output);

print_r($output);

当然，这是可以过滤的

例如，在您的示例中，通过添加一个小的foreach循环…：

$page = file_get_contents("http://www.comuni-italiani.it/province.html");

    $output = array();
    preg_match_all('/<td.*.<\/td>/',$page,$output);

    $provinces = array();

    foreach ($output as $id => $list) {
        for ($i = 2; $i <= 111; $i++) {
            array_push($provinces,$list[$i]);
        }
    }

    print_r($provinces);

（为巨大的阵列感到抱歉）

但是，它将链接保留在数组中，因此，如果您只想获取值而不想获取与之关联的锚点，可以随意使用另一个正则表达式

希望这有帮助

（以此为例，请记住，如果页面发生更改，此foreach技巧可能不再有效，我发布它只是为了让您了解如何解决该问题）。

非常感谢，但如果我想添加“sigla”专栏

$page = file_get_contents("http://www.comuni-italiani.it/province.html");

    $output = array();
    preg_match_all('/<td.*.<\/td>/',$page,$output);

    $provinces = array();

    foreach ($output as $id => $list) {
        for ($i = 2; $i <= 111; $i++) {
            array_push($provinces,$list[$i]);
        }
    }

    print_r($provinces);
