用 PHP 写了一个

links.php
```
<?php
require __DIR__ . '/vendor/autoload.php';

global $base_uri, $wait_replace_imgs;
$base_uri = 'https://www.v2ex.com';
$t1 = microtime(true);
try {
set_time_limit(1800);
ini_set("max_execution_time", 1800);
ini_set('memory_limit', '512M');
$html_node = file_get_contents($base_uri);
$crawler = new \Symfony\Component\DomCrawler\Crawler($html_node, $base_uri);
$links = $crawler->filter('a')->links();
foreach ($links as $link) {
$temp_links[] = ['url' => $link->getUri(), 'text' => $link->getNode()->textContent];
}
file_put_contents('links.txt', json_encode($temp_links, JSON_UNESCAPED_UNICODE));
echo 'success<br/>';
$t2 = microtime(true);
echo 'time consuming ' . round($t2 - $t1, 3) . ' s' . PHP_EOL;
} catch (Exception $exception) {
echo $exception->getCode() . ', message:' . $exception->getMessage();
}
```
部分效果
