can you see name=himanshu if you put echo statement outside the while loop??

himanshu.1691 0 Newbie Poster · Answer 3 · 2012-02-20T18:36:05+00:00

finally i understood.....
the problem was with the scope of the functions.
i was not able to access the variables outside the functions...
i removed it and it works fine now :D
Thanks for your replies bhailog :D

I rewrote the code for mysql, its almost same as oracle, maybe you could learn something from it?

SQL data

CREATE TABLE IF NOT EXISTS `him_details` (
  `NAME` varchar(25) DEFAULT NULL,
  `BRANCH` varchar(25) DEFAULT NULL,
  `SMOBILE` int(11) DEFAULT NULL,
  `ENO` int(11) DEFAULT NULL,
  `HOSTEL` varchar(25) DEFAULT NULL,
  `ROOM` varchar(25) DEFAULT NULL,
  `FMOBILE` int(11) DEFAULT NULL,
  `ADDRESS` varchar(25) DEFAULT NULL
)

INSERT INTO `him_details` (`NAME`, `BRANCH`, `SMOBILE`, `ENO`, `HOSTEL`, `ROOM`, `FMOBILE`, `ADDRESS`) VALUES
('first user', 'london', 123456789, 1, 'hostel', '22', 123456789, 'london, uk'),
('second user', 'oxford', 2147483647, 2, 'hotel', '14', 564789123, 'oxford, uk');

PHP

<?php
	$details = array(); 
	$username ='root';
	$password = '';
	$server =  'localhost';
	$database = 'orcl';
	$connection =  @mysql_connect($server,$username,$password);
	if($connection) {
		$db = @mysql_select_db($database);
		if($db){
			$query = @mysql_query("SELECT * FROM him_details");
			if($query){
				$details = @mysql_fetch_array($query);
			}
			else {
				die(mysql_errno()." ".mysql_error());
			}
			
		}
		else {
			die(mysql_errno()." ".mysql_error());
		}
	}
	else {
		die(mysql_errno()." ".mysql_error());
	}
?>
