php - $result = mysql_query()

I am brand new to php/mysql, so please excuse my level of knowledge here, and feel free to direct me in a better direction, if what I am doing is out of date.

I am pulling in information from a database to fill in a landing page. The layout starts with an image on the left and a headline to the right. Here, I am using the query to retrieve a page headline text:

<?php
$result = mysql_query("SELECT banner_headline FROM low_engagement WHERE thread_segment = 'a3'", $connection);
if(!$result) {
    die("Database query failed: " . mysql_error());
}
while ($row = mysql_fetch_array($result)) {
    echo $row["banner_headline"];
}
?>

This works great, but now I want to duplicate that headline text inside the img alt tag. What is the best way to duplicate this queries information inside the alt tag? Is there any abbreviated code I can use for this, or is it better to just copy this code inside the alt tag and run it twice?

Thanks for any insight!

You are, as the comment says, using deprecated functions, but to answer your question, you should declare a variable to hold the value once your retrieve it from the database so that you can use it whenever your want.

<?php
$result = mysql_query("SELECT banner_headline FROM low_engagement WHERE thread_segment = 'a3'", $connection);
if(!$result) {
    die("Database query failed: " . mysql_error());
}

$bannerHeadline = "";

while ($row = mysql_fetch_array($result)) {
    $bannerHeadline = $row["banner_headline"];
}

echo $bannerHeadline; //use this wherever you want

?>
