display comments under each image - php

Question

I want to display all the comments posted under each image from a database.
I tried the following code, but I was able to get only one comment, which was the last one posted.
$sql1="SELECT user,comment FROM comment_table where imagename=:file";
$q1=array(':file'=>$file);
try {
$stmt = $pdo->prepare($sql1);
$stmt->execute($q1);
$stmt->setFetchMode(PDO::FETCH_BOTH);
$result= $stmt->fetch();
$c = $result["comment"];
$u=$result["user"];
}
catch (PDOException $e) {
die("Failed to run query: " . $e->getMessage());
}
echo "<tr><td>".$u.":".$c."</td><tr>";
Please help needed and appreciated.

You need to create a foreach to print all the comments. Take a read here http://php.net/manual/en/control-structures.foreach.php
With your code it just shows one comment, so try this:
$sql1="SELECT user,comment FROM comment_table where imagename=:file";
$q1=array(':file'=>$file);
try {
$stmt = $pdo->prepare($sql1);
$stmt->execute($q1);
$stmt->setFetchMode(PDO::FETCH_BOTH);
$result= $stmt->fetch();
catch (PDOException $e) {
die("Failed to run query: " . $e->getMessage());
}
foreach ($result as $res) {
echo "<tr><td>".$res["user"].":".$res["comment"]."</td><tr>";
}
