Question

I am using the PHP readfile function to read a file and print it like so: print readfile ('anyfile'). This works, but the content length of the file is added at the end of the string also. Why?

Answer 1

readfile() prints out the contents itself and returns the content length — you’re effectively printing the contents with readfile and then printing the content length with print. Remove print and just use

readfile('anyfile');
