    file_get_contents with GET request only passing first parameter

    Hello.

    I have a JavaScript frontend using GET to call a PHP script that accesses a servlet. However, the servlet is only receiving the first parameter of the GET, and all of the others are null. This is my PHP script:

    PHP Code:
    <?php
        $getdata 
    http_build_query($_GET);

        
    $opts = array('http' =>
            array(
                
    'method'  => 'GET',
                
    'header'  => 'Content-type: application/x-www-form-urlencoded',
                
    'content' => $getdata
            
    )
        );

        
    $context  stream_context_create($opts);
        
    $servletURL  'http://localhost:8182';
        
    $result file_get_contents(servletURLfalse$context);
        echo 
    $result;
    ?>
    My servlet is using form processing with getFirstValue("value1"), getFirstValue("value2") ... etc, but all parameters after the first are null. Is there something wrong with my PHP?

    Have you tried to echo $getdata to see if it contains the right info?

    The data it contains is this:

    'username=myusername&amp;password=mypassword&amp;company=mycompany'

    I was able to solve my problem by using getFirstValue("username") as usual, then for the rest of the parameters, use getFirstValue("amp;password"), getFirstValue("amp;company").

    Thanks for your help. That certainly fixed my problem. Sure feels like a hack though.

    You should be using "&" rather than "&amp;" for the URL. "&amp;" is an HTML character entity, but you are not outputting HTML, you are transmitting a HTTP request.

    I am not doing anything of the sort. The http_build_query() call is putting those amps in, and do not know how to ask it not to.

    Then replace all "&amp;" with "&" after you get the string back...doesn't have to be that difficult.

    Or you could pass it as a serialize array in one variable and unserialize it.

    That is a hack. Best to fix the input on the way out rather than create extra work on both sides of the exchange.
