如何在.jpg链接中显示Blob中的.jpg图像

Question

I've a issue. I want to display .jpg image from blob.

I can display it in scripts. For example...

<?php
 $db = mysqli_connect('xxxxx', 'xxxxxx', 'xxxx', 'xxxxx');
 if (mysqli_connect_errno()) {
 echo "Failed to connect to MySQL: " . mysqli_connect_error();
 }
 foreach ($db->query("SELECT * FROM `pictures` WHERE imageID = 3") as $result) {

 header("Content-type: image/jpeg");

 $img = $result['img'];
 print $img;
 }
?>

In index page is this link:

echo '<img src="/wszystko/obiektowy_obrazki/img.php">';

And now... I want to display It by this link:

echo '<img src="/wszystko/obiektowy_obrazki/$img.jpg">';

How can I do It? Thanks for help.

Answer 1

echo "<img src=\"/wszystko/obiektowy_obrazki/$img.jpg\">";

OR

echo "<img src='/wszystko/obiektowy_obrazki/$img.jpg'>";

Or (more cleaner)

$path = '/wszystko/obiektowy_obrazki';
$image = $path . '/' . $img . '.jpg';
print '<img src="' . $image . '">';
