PHP preg_match显示Array（）

Question

我是PHP的新手，我正试图从预测网站中获取天气摘要数据，我尝试了一切我发现但它只返回Array（）

<?php

$contents=file_get_contents("http://www.weather-forecast.com/locations/Podgorica/forecasts/latest");

preg_match('/ <a class="forecast-magellan-target" name="forecast-part-0"><div data-magellan-destination="forecast-part-0"><\/div><\/a><p class="summary"> (.*?)  <\/span><\/p> /is',$contents, $matches);

print_r($matches);



?>

Answer 1

你有额外的空格，请试试这个：

preg_match('/<a class="forecast-magellan-target" name="forecast-part-0"><div data-magellan-destination="forecast-part-0"><\/div><\/a><p class="summary">(.*?)<\/span><\/p>/is',$contents, $matches);
