title: How to check if my form is reaching the post limit
body: <p>I have a large HTML form which I think is reaching the php post limit because the last parts of the data are getting missed off although it there anyway to test/be sure that this is the cause? </p>
  
  <p>I understand this can easily be fixed by increasing the php.ini values, but is there anyway in PHP to check this is the cause in PHP? </p>
  
  <p>e.g: it writes a log showing the amount of posted data sent by the form and checks this against the value in the php.ini</p>
