PHP upload to blob on the fly
===

I have a simple input form which contains an input type="file" with name="pdf_statement".

I want to be able to upload the content and insert into the database on the fly. As this is only a test file I am not worried about security (i will add once the functionality is in place).

I have read http://php.net/manual/en/function.stream-get-contents.php but cannot get this to work. I get errors *fopen() expects parameter 1 to be string, array given* and *stream_get_contents() expects parameter 1 to be resource, boolean given*.

I'm sorry if this is blindingly obvious but for someone who is learning I cannot figure out what I am doing wrong.

    <?php

    include('session.php');

    $provider      =$_POST['provider_id'];
    $trd_period    =$_POST['trading_period_month'];
    $pdf_statement =stream_get_contents(fopen($_FILES['pdf_statement'], 'r'));
  
    $sql_qry="update rd_provider_statement
              set (pdf_statment='".$pdf_statement."', creation_user_id='SCO')
              where  provider='".$provider."' and trading_period_month='".$trd_period."'";
    $sql_err_no=sql_select($sql_qry,$sql_res,$sql_row_count,$sql_err,$sql_uerr);    

    ?>
