将参数$ argv从html表单传递给脚本

how can i pass the arguments file (argv1) and subfile(argv2) from this website-form:

<h2>This form allows you to upload a Video.</h2>
<form action="uploadapi.php" method="post" enctype="multipart/form-data">
    <br>
    <p>
        Video Name: 
        <input type="text" name="titel" size="50" />
    </p>
    <p>
        Video Description:
        <br/>
        <textarea name="text" rows="5" cols="50"></textarea>
    </p>
    <p>
        Select File, allowed: .mpg 
        </br>
        <input type="file" name="file">
    </p>
    <p>
        Select File, allowed: .src 
        </br>
        <input type="file" name="subfile">
    </p>
    <p>
      <input type="submit" value="Upload">
    </p>
</form>

to my uploadapi.php script witch needs: $file = $argv[1] and $file = $argv[2]. this uploadapi.php script also needs to be executed via exec.
