Comments  in PHP


A comment  in PHP code  is a line that  is not read/exe­ cuted  as part of the program.  Its only  purpose  is to be read by someone  who is editing  the codel

Comments  are useful  for :-

To let others  understand  what you are doing - Comments  let other  programmers understand  what  you were  doing  in each step (if you work  in a group)

To remind  yourself  what  you did - Most programmers have experienced   coming  back to their  own work  a year or two later  and having  to re-figure  out what  they  did. Comments  can remind  you of what you were thinking when  you wrote  the code.
