+// Pointless commenting example:

+$password    = mysql_real_escape_string($_POST['password']); # Get password
+$age         = intval($_POST['age')];  #Get age

+
+// The above is useless because it's quite obvious of what's happening.

+# Get information from POST

+
+Why comment like that at the beginning of a function? It will save a lot of time. Saves the person reading from having to go through the code for that function.
