PHP download file from link that downloads file

I'm trying to use PHP to download files that are created and downloaded when you call to a URL.

In this case I'm trying to programmatically download a txt file from the Dutch weather institute which can be done by going to (in this example) this URL http://projects.knmi.nl/klimatologie/daggegevens/getdata_dag.cgi?lang=nl&byear=2016&bmonth=6&bday=20&eyear=2016&emonth=6&eday=22&variabele=FHX&variabele=FXX&variabele=TG&variabele=TN&variabele=TX&stations=249&submit=Download+data+set

Going to that URL downloads the file.

I want to do this with PHP so I can use the contents of the file to make custom charts.

Does anyone know how to do this with PHP?

Using file_get_contents(): http://php.net/manual/en/function.file-get-contents.php

or using CURL functions: http://php.net/manual/en/function.curl-exec.php

EDIT: CURL Solution:

$url = 'http://projects.knmi.nl/klimatologie/daggegevens/getdata_dag.cgi?lang=nl&byear=2016&bmonth=6&bday=20&eyear=2016&emonth=6&eday=22&variabele=FHX&variabele=FXX&variabele=TG&variabele=TN&variabele=TX&stations=249&submit=Download+data+set';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
$str = curl_exec($curl);
