I have live chat that is supposed to display the "sender" and the "message", but instead give me some weird result.
script:
function get_msg(){ global $con; $query = "SELECT Sender, Message FROM chat"; $run = mysqli_query($con, $query); $messages = array(); while($message = mysqli_fetch_assoc($run)){ $messages = array('sender' => $message['Sender'], 'message' => $message['Message']); } return $messages; }
<div id="messages"> <?php $messages = get_msg(); foreach($messages as $sender => $message){ echo "Sender: " . $sender . "<br >"; echo "Message: " . $message . "<br />"; } ?></div>
this is what it outputs:
Message has been sent.
Sender: senderMessage: hiSender: messageMessage: message

this is a little reference from my live chat script, but it wont work. The error message is variable $con is not defined, but it is clearly defined.
$con = mysqli_connect("localhost","root","123","chat") or die(mysqli_error($con));function get_msg(){ $query = mysqli_query($con, "SELECT Sender, Message FROM chat"); $run = mysqli_query($con, $query); $messages = array(); while($message = mysqli_fetch_assoc($run)){ $messages = array('sender' => $message['Sender'], 'message' => $message['Message']); } return $messages; }

you should use a while loop instead.

$data1 = $rows['data1'];
echo "$data1 <br />";

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1' at line 1
<?phpinclude "conn.php";$name = mysqli_real_escape_string($con, $_POST['name']);$details = mysqli_real_escape_string($con, $_POST['details']);$photo = addslashes(file_get_contents($_FILES['photo']['tmp_name']));$image = getimagesize($_FILES['photo']['tmp_name']);$imagetype = $image['mime'];echo "<br/>";$q = mysqli_query($con, "INSERT INTO animal VALUES('','$name','$details','$photo','$imagetype')") or die(mysqli_error($con));$r = mysqli_query($con, $q);if($r){ echo "information stored";}else{ echo mysqli_error($con);}?>

live support
in PHP
is there a website where i can get live php support?

Databases can save any type of data. The BLOB field stands for Binary Large OBject and can be used to store the contents of any file including image or video.
Given that, I still find it preferrable to store file data in the filesystem rather than the database.
do u mean in a folder?

But if i save an address that refers to my image or video, should it be in a BLOB type?
I mean what is BLOB. Answer my above questions.

when people upload image or video to my site, do i store them in any special type in phpmyadmin?
are you supposed to use BLOB?
What is BLOB?
Which of them do i use? I would guess they can store different amount of data, how much do each of them store?
