I’m using PHP’s function
file_get_contents() to fetch contents of a URL and then I process headers through the variable
Now the problem is that some of the URLs need some data to be posted to the URL (for example, login pages).
How do I do that?
I realize using stream_context I may be able to do that but I am not entirely clear.
Sending an HTTP POST request using
file_get_contents is not that hard, actually : as you guessed, you have to use the
There’s an example given in the PHP manual, at this page : HTTP context options (quoting) :
$postdata = http_build_query( array( 'var1' => 'some content', 'var2' => 'doh' ) ); $opts = array('http' => array( 'method' => 'POST', 'header' => 'Content-Type: application/x-www-form-urlencoded', 'content' => $postdata ) ); $context = stream_context_create($opts); $result = file_get_contents('http://example.com/submit.php', false, $context);
Basically, you have to create a stream, with the right options (there is a full list on that page), and use it as the third parameter to
file_get_contents — nothing more 😉
As a sidenote : generally speaking, to send HTTP POST requests, we tend to use curl, which provides a lot of options an all — but streams are one of the nice things of PHP that nobody knows about… too bad…
