may I ask for help? I cannot show out the result. If I run the code without the SUM operator, it works properly. Please help, thank you very much.
$sql1 ="SELECT SUM(SeatAmount) FROM reservation
WHERE RsvDate BETWEEN '07/01/2013' AND '07/31/2013'";
$result1 = $con->query($sql1);
printf('<td>');
printf('<b>Seat Amount</b><br/>');
while ($row1 = $result1->fetch_object())
{
printf('
%d<br/>',$row1->SeatAmount);
}
In order for that to work, you'd need an alias:
SELECT SUM(SeatAmount) AS SeatAmount
what is $row1's structure?
You can specify what the sum should be returned as like:
SELECT SUM(SeatAmount) AS SeatAmount
$sql1 ="SELECT SUM(SeatAmount) AS Total FROM reservation
WHERE RsvDate BETWEEN '07/01/2013' AND '07/31/2013'";
$result1 = $con->query($sql1);
printf('<td>');
printf('<b>Seat Amount</b><br/>');
while ($row1 = $result1->fetch_object())
{
printf('
%d<br/>',$row1->Total);
}

You can explode the data, modify it, then re-implode it.
$data = 'C00001,C00302,C00303,C00287,C00286,C00285,C00017';
$arr = explode(',', $data);
$new_arr = array_map(function($a){
return "'{$a}'";
}, $arr);
$new_data = implode(',', $new_arr);

Can anyone please tell me , how to fetch names from mysql through php and then put all those names in hmtl select tag for user to choose one name
use a foreach
echo "<select name='username'>";
while($row=mysql_fetch_array($r))
{
$user=array( $row['fieldname']);
foreach($user as $val)
{
echo "<option value='\$val\'>".$val."</option>";
}
}
echo "</select>";
Hope this helps
Check here.
Hints are
// sql connection here
$query="SELECT * FROM emp";
$result=mysql_query($query);
while($r=mysql_fetch_array($result)
{
echo $r[0];
// all the row that u want to fetch
}
Use PDO. It let's you access the data from SQL which you can then output in a select.

What's wrong with this? It returns "You have an error in your syntax... ...check if you have the right MySQL version to use near 'to, content, link) VALUES..."
$notito = $idoftheguy;
$contentofnoti = $username." just posted a comment on your update.";
$linkofnoti = "http://mywebsite.net/post.php?id=".$thepostid;
/* Now let's insert this */
$insertnoti = mysql_query("INSERT INTO newnotifications (to, content, link) VALUES ('$notito', '$contentofnoti', '$linkofnoti')");
All of the above things in the query are existent in the database. And here are the exact inputs that gave the error (haven't tried any other inputs):
$notito = 1;
$contentofnoti = "Schart just posted a comment on your update.";
$linkofnoti = "http://mywebsite.net/post.php?id=22";
As already mentioned. to is a reserverd word. Try this code:
$insertnoti = mysql_query("INSERT INTO newnotifications (`to`, `content`, `link`) VALUES ('$notito', '$contentofnoti', '$linkofnoti')");

$a='Would you like to have responses to your questions sent to you via email'
for($a as $b=>c){
}
Kindly give me the solution
<?php echo substr_count($a, 't'); ?>
Here's a solution, though not necessarily the best
$letterCount = array_count_values(
str_split(strtolower($a))
);
$tCount = (isset($letterCount['t'])) ? $letterCount['t'] : 0;
$count = preg_match_all('/t/', $str);
check this one
<?php
$a = 'Would you like to have responses to your questions sent to you via email';
$t_explod = explode('t', strtolower($a));
echo count($t_explod) - 1;
?>
