How to display source code in PHP
I want to use PHP to display the source code, is placed in the TXT, but with fgetc () or fread () read the file, it is displayed in the TXT code parsing content, I want to directly display the source code and not the parsed content, what methods do you have?

------Solution--------------------
Manifested output

echo htmlentities ($phpCode);

Is it impossible? Fread read local files are plain text, without being parsed by PHP AH
Don't you want to see the source code of the PHP file on the server?
------Solution--------------------
Your code
