在PHP脚本中显示BLOB文件

Question

This is my PHP script which displays a radio station's schedule:

    <div class="divider"></div>
    <div class="main" style="width:552px;">
        <img src="$image" width=115 height=60>
        <div class="time">$airtime</div>
        <div class="show"><h3><a href="$link><b>$presenter</b></a></h3>
            <p>$showdesc</p></div>
        <div class="footer"></div>
    </div>
    </div>
                <div class="footer"></div>
                <div class="bottom"></div>
            </div>

The values with the dollar sign represent the field names in my database, which is radiopresenters.

How would I get this to work as a PHP script, and display the values from the database? All values in the fields are stored in TEXT format, apart from the image field which is stored in BLOB format.

Airtime is stored in a separate database entitled as radioschedule which has all 4 fields ib, and I intend to link these together via some relational means.

What's the best way to get it to display as the above, especially the BLOB part?

Answer 1

Are you asking how to put those values into your file?

As for the text ones you could just use

<?=$airtime?> 

or if your server setup doesn't support short tags just use

<?php echo $airtime?>

I would just do this inline with your php.

Example:

<div class="time"><?=$airtime?></div>

As for the BLOB, I would advise not doing this and just storing the image on your server and store the image file's name in the db. BUT if you are intent on doing this I think the only way you can do this is by having a separate script that returns an image file. Something like this:

<?php 
// Do all your db stuff here, grab the blob file. Probably from a $_GET paramater
$image = $row['image'];
header("Content-type: image/jpeg"); // or gif, etc...
echo $image;
die();
?>

Then in your other file you would do something like:

<img src="imagescript.php?person_id=<?=$person_id?>" width=115 height=60>
