currently changed a machine application, so the barcode image no longer appears. The PHP version of this new machine is newer, I tried to change the image call but nothing happens. How could I fix?

   <?php
      echo "<IMG src='barras.php?num=" .$codigobarras." '>";             
   ?>

Barcode (.php bars)

<?

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

$bf = 1;
$ab = 50;
if ($bf == "")
{
    $tamxt = 1;
    $tamxl = 3;
}
else
{
    $tamxt = $bf;
    $tamxl = ($bf * 2) + 1;
}   

if ($ab == "")
    $tamy = 50;
else
    $tamy = $ab;

$aux_len = strlen($num)%2;

if ($aux_len != 0)
    $aux_len = (strlen($num) + 1) / 2;
else
    $aux_len = strlen($num) / 2;

$aux_tamx = ((6 * $tamxt + 4 * $tamxl) * $aux_len) + (6 * $tamxt) + $tamxl;


$im = ImageCreate($aux_tamx, $tamy);

There are three possible problems that may have caused the failure:

You used <? instead of <?php, recommend that you always use <?php.

You used $num instead of $_GET['num']

To solve this problem, add at the beginning of the script this:

    <?php
    $num = $_GET['num'];

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

    $bf = 1;
    $ab = 50;
    if ($bf == "")
    {
       $tamxt = 1;
       $tamxl = 3;
    }
    else
    {
       $tamxt = $bf;
       $tamxl = ($bf * 2) + 1;
    }

GD library is disabled.

The GD library is responsible for the imagecreate, imagecolorallocate, etc. To activate it you will need to configure the php.ini, look in php.ini for a line similar to is:
```
;extension=php_gd2.dll
```
Remove the ; start and save the file, if this line does not exist then add this to the file:
```
extension=php_gd2.dll
```
If you are using a Debian or Ubuntu distribution (linux servers) then you should also run this line on the terminal:
```
$ sudo apt-get install php5-gd
```
(However I believe that GD is already installed, since it previously worked).

After this restart the server and re-test the script.

"Debugging" the script

If none of this works, then you can try to test your file because it may be a problem on your server that only you can detect, to "debug" your script do the following:

Comment the header thus:
```
    <?php
    $num = $_GET['num'];

    //Header("Content-type: image/jpeg");
```
- Open your file directly in the web-browser/browser without using the <img>, something like:
  
  http://localhost/project/bar.php? num=1
  
  You will probably get an error, enter this error in your question or comment here.

Hint about HTML and PHP

Your php is like this:

echo "<IMG src='barras.php?num=" .$codigobarras." '>";

When executed it processes this for example:

<IMG src='barras.php?num=5 '>

Note that there was a gap at the end, although it does not affect your script, this does not seem right. I also recommend:

Use apostrophes for PHP and quotation marks for HTML
When to use echo use , instead of points
Use html tags in minusculo

Should stay like this:

echo '<img src="barras.php?num=', $codigobarras, '">';

These tips won’t make much difference, but help make the code a little better to work with.
