Writing Problems

Dear List - I can't figure this one out..... 1] Straighten out ownership ethan@meow:/var/www$ rm receipt.txt ethan@meow:/var/www$ touch receipt.txt ethan@meow:/var/www$ ls -l receipt.txt -rw-r--r-- 1 ethan ethan 0 Aug 26 19:31 receipt.txt ethan@meow:/var/www$ chmod 766 receipt.txt ethan@meow:/var/www$ ls -l receipt.txt -rwxrw-rw- 1 ethan ethan 0 Aug 26 19:31 receipt.txt This is what we want 2] Now program code .... ini_set('display_startup_errors', 'on'); error_reporting(E_ALL | E_NOTICE); ini_set('display_errors','1'); error_reporting(1); $fh2 = fopen("/var/www/receipt.txt", "a+"); want this file to be like a cash register receipt. I can truncate this file for each execution of the program; ie, when all the purchases are finished. $sql3 = "select quant, orderpt, ordrpt_flag, manuf, item, stock, price, tax_flag from Inventory where UPC = $upc"; $result3 = mysqli_query($cxn, $sql3); $row3 = mysqli_fetch_row($result3); print_r($row3 ); //gives correct results. $numbyt=fprintf($fh2, "%s %s %.2f %s\n",$row3[3] , $row3[4], $row3[6], $row3[7]); echo "<br />numbyt fh2 $numbyt<br />"; //result is 0 No errors. What is wrong?? TIA Ethan
