title: Can I limit PHP to just the file it's in (stop abuse?)
body: <p>I'm making a small file editor and the only kicker is I don't want the people who have access to it do use dangerous functions like unlink chdir exec and I'm sure there's 100 more they shoudln't be able to use.</p>
  
  <p>I was thinking of just making an array of dangerous functions I don't want them to be able to use and when they save the file just str_replacing them out but the problem with that is what if I leave out several dangerous functions?</p>
  
  <p>So with that I was hoping that either A) someone could give me a list of functions that people could abuse within PHP, OR B) give me a better solution to this problem.</p>
  
  <p>Note I'm not the server admin so I'd only be able to use htaccess if you can help with the latter</p>
