You can also set your error handler as an anonymous function that calls an Exception and use a try   catch on that exception   set error handler      function   severity   message   file   line            throw new ErrorException  message   severity   severity   file   line             try       file get contents  www google com      catch  Exception  e        echo  e- gt getMessage       restore error handler      Seems like a lot of code to catch one little error  but if you re using exceptions throughout your app  you would only need to do this once  way at the top  in an included config file  for instance   and it will convert all your errors to Exceptions throughout

One alternative is to suppress the error and also throw an exception which you can catch later  This is especially useful if there are multiple calls to file get contents   in your code  since you don t need to suppress and handle all of them manually  Instead  several calls can be made to this function in a single try catch block      Returns the contents of a file function file contents  path         str    file get contents  path       if   str     FALSE            throw new Exception  Cannot access   path  to read contents           else           return  str              Example try       file contents  a        file contents  b        file contents  c      catch  Exception  e           Deal with it      echo  Error       e- gt getMessage
