If possible to change your code then better approach from HTML point of  
view is to declare your input variable as an array itself like shown below.

<input type="text" name="bid_sub_desc[]" value="val1" />
<input type="text" name="bid_sub_desc[]" value="val2" />
<input type="text" name="bid_sub_desc[]" value="val3" />

By this way you will receive values of all these input fields into single  
array "$_POST['bid_sub_desc']". Then you can do rest of stuffs with it  
just like you do with normal php array without bothering about handling  
"$i", "quotes", "expansion" and "concatenation"

Thanks
