string concatenattion

hi, i have an array of strings and would like to create a single string from the array but starting somewhere in the middle of the array index and not from the start, is there any function for me to do a string concatenation. ive gone thro the manula and didnt find any, but if u have any bright ideas how this can be achieved, pls help. roslyn <?php $conn=pg_connect("host=abcd.... dbname=ucs user=roslyn password=roslyn"); $filename="note.txt"; $fp = fopen ($filename,"r"); $cnt=3; $buffer=file($filename); //pg_exec ($conn, "insert into books(name,sequenceno,chapters,lang) values('$buffer[0]',1,$buffer[1],1)"); $i=2; while($i <= $cnt) { $str = buffer[$i]; $i++; } echo $str; fclose ($fp); ?> this string only prints the last element in the buffer, and no concat is done. pls help --------------------------------- Do you Yahoo!?
