[extemer]

here is my code want to get records between two dates

$sql=mysql_query("SELECT * FROM `expense` WHERE `date` BETWEEN '2011-04-26' AND '2011-04-28'")
 
 or die(mysql_error());

echo $r=mysql_fetch_assoc($sql);

i getting "Array" in output instead of the data please sort it out for me i am not getting it right

[hielo]

$sql=mysql_query("SELECT * FROM `expense` WHERE `date` BETWEEN '2011-04-26' AND '2011-04-28'") or die(mysql_error());

$r=mysql_fetch_assoc($sql);

//SELECT * ... assuming that the * includes some field named `id`, then the following
//will print it's contents:
echo $r['id'];


//if you want to see everything at once, use:
print_r($r);

when wrote this code

$sql=mysql_query("SELECT * FROM `expense` WHERE `date` BETWEEN '2011-04-26' AND '2011-04-28'")
 
 or die(mysql_error());

$r=mysql_fetch_assoc($sql);
print_r($r);

i got this output
Array ( [rec_no] => 5 [date] => 2011-04-26 [detail] => dddd [amount] => 111 )

why i am getting this array print again and again cant i get it without array

[hielo]

why i am getting this array

Because that's what print_r() does.

can't i get it without array

echo/print them individually - ex: echo $r['rec_no'] . ' ' . $r['date'].'<br>'; Or for all of them (without Array): echo implode(' ', $r).'<br>';

thanks anyways but i am not getting the full records between date 26th to 29th it just display the first mention date e.g

WHERE `date` BETWEEN '2011-04-26' AND '2011-04-29'

it only print me one record that of date '2011-04-26' but i want it to print all records in between date 26 till to 29..

[hielo]

you need to iterate over the entire result set:

...
$sql=mysql_query("SELECT * FROM `expense` WHERE `date` BETWEEN '2011-04-26' AND '2011-04-28'")
 
 or die(mysql_error());

while( $r=mysql_fetch_assoc($sql) )
 echo implode(' ',$r).'<br/>';
}

brother i have come out with this way and this works

$sql=mysql_query("SELECT * FROM `expense` WHERE `date` BETWEEN '2011-04-26' AND '2011-04-29'");


echo "<center><table bordercolor='#000000' border='3' >";

while( $r=mysql_fetch_assoc($sql) )
{
	
	$new=implode(' ',$r).'<br/>';
echo "</tr><td>$new</td>";

}

echo "</tr></table></center>";

[hielo]

the table markup you are emitting is not correct. Also, there's no need to save it onto $new .
Try:

$sql=mysql_query("SELECT * FROM `expense` WHERE `date` BETWEEN '2011-04-26' AND '2011-04-29'");


echo '<center><table bordercolor="#000000" border="3" >';

while( $r=mysql_fetch_assoc($sql) )
{
	
  echo '<tr><td>' . implode(' ',$r) . '</td></tr>';

}

echo '</table></center>';

this will display me all the amount field from 26th date till 29th and if i want to add that all amount display how would i perform that..i would use sum function instead the while loop

<?php
error_reporting(0);
mysql_connect("localhost","root",""); 
mysql_select_db("new"); // connect to database


 $sql=mysql_query("SELECT * FROM `expense` WHERE `date` BETWEEN '2011-04-26' AND '2011-04-29'");
  


echo '<center><table bordercolor="#000000" border="3" >';
//
while( $r=mysql_fetch_assoc($sql) )
while($r1=mysql_fetch_assoc($new)){
	echo $r1['amount'];
{


echo '<tr><td>' . $r['amount'] .'<br>'. '</td></tr>';
 

}
}
echo '</table></center>';


?>

if you want every record AND the sum, then initialize a $total=0; variable outside the while. Then within the while put $total+=$r['amount']; . After the while, $total should have the sum.

If all you want/need is the sum, then do a SUM query.
