conversion

how i convert a php statement into comments in a run time

 

You can't. Why would you want to do that?

 

Improve your logic, that doesn't make much sense

 

I don't understand what you want to say.

 

I assume that he wants to exclude code at certain times or conditions.

I guess a IF statement would be the suitable option here.

 

dear you can,t understand .
i explain it
i make a php programme which have 15 statements
i want to count them with a specific no such 5 so the next time statement no 5
are become comment or delete how i do it

 

why do you want do delte or comment a code line at runtime? Do you want to prevent it's executiion? Then use if statements as stephan2307 already said. I still can't understand what you want.
You have 15 statements in your script and want to randomly exclude one from execution?

 

yes i want to exclude selected statement,
when ever the loop is run

 

well why don't do yo something like this

if ($no != 1) { 
  //run this code
}
if ($no != 2) { 
  //run this code
}
if ($no != 3) { 
  //run this code
}
if ($no != 4) { 
  //run this code
}
if ($no != 5) { 
  //run this code
}
if ($no != 6) { 
  //run this code
}
