In php how to display mysql results? - php

Question

I have a mysql table in which I keep e-mail addresses. The structure is as follows:
id || email
However, how do I actually output those e-mail addresses, separated by commas, in php?
Thanks in advance for your help!

Answer 1

Use:
<?php
$query = "SELECT GROUP_CONCAT(t.email) AS emails
FROM YOUR_TABLE t"
// Perform Query
$result = mysql_query($query);
while ($row = mysql_fetch_assoc($result)) {
echo $row['emails'];
}
// Free the resources associated with the result set
// This is done automatically at the end of the script
mysql_free_result($result);
?>
References:
mysql_query
GROUP_CONCAT

You probably need to read up on the basics, it's not complicated and will only take a few minutes to glance over it and get you started.

Option 1:
$sql = "SELECT GROUP_CONCAT(email ORDER BY email ASC SEPARATOR ', ') AS emails FROM emails";
$res = mysql_query($sql);
list($emails) = mysql_fetch_row($res);
echo $emails;
Option 2, so you can do more with all the emails later on:
$emails = array();
$sql = "SELECT email FROM emails ORDER BY email ASC";
$res = mysql_query($sql);
while ($r = mysql_fetch_object($res)) {
$emails[] = $r->email;
}
// as a list
echo implode(', ',$emails);
// or do something else
foreach ($emails as $email) {
// ...
}

Do something like:
while ($output = mysql_fetch_array($query_results)) {
echo $output['id'] . ", " . output['email'];
}
