title: Using ini_set(“memory_limit”, “-1”)
body: <p>I used  <code>ini_set('memory_limit', '-1')</code> in my code php.
  I googled it and I searched more, I found that I should change the <code>"-1"</code> to increase the size of the memory, but I work directly on the server of production, I change my file then I deploy it.</p>
  
  <p>It have an effect when I upload or download the files ?
  It can a cause of the loss of my information when I do the dowload from Highchart ?</p>
