PHP-在textarea中显示数据

Question

My goal is to display all emails inside a text area.

<?php 
$q = "SELECT * FROM `Clients`";
$userData = mysql_query($q);

while($user = mysql_fetch_assoc($userData)){
    echo $user['Email'];
}
?>

it should echo all info into here:

<input type="text" name="text" >

I get the information fine from the DB, but im not sure how to echo the ALL the data into a SINGLE text field..

Answer 1

PHP Code

$userData = mysql_query($q);
$userEmails = array();
while($user = mysql_fetch_assoc($userData)){
    $userEmails[] = $user['Email'];
}

HTML (example with a comma separated email string)

<input type="text" value="<?php echo implode(', ', $userEmails); ?>" />

Answer 2

You need to do in following manner:-

<?php 
$q = "SELECT * FROM `Clients`";
$userData = mysql_query($q);
$email = array(); // create an array
  while($user = mysql_fetch_assoc($userData)){
       $email[] =  $user['Email']; // assign each email to that array
  }
?>

<textarea><?php echo implode(','$email);?></textarea> // implode the array by `,` now all emails will show wiith `,` seperation.

Note:- this is the way how you need to do. Checking variables and do the necessary changes is on you. thanks.
