Are you referring to the HEREDOC syntax?

Yup, that's it - HEREDOC syntax is what was referring to - thanks - and,
here's a better version of some output - since you don't seem to be able to
specifically include PHP code itself within delimiters, although you can
output variables, etc.:
<?php
$var1 = "hulloWorld";
print <<<HTML
<table align="center" border="1">
<tr>
<th colspan="2">$var1</th>
</tr>
<tr>
<th>Caption</th><td>column</td>
</tr>
</table>
HTML;
?>
Stay well

That's just a piece of it, so don't worry about HTML markup missing
pieces - more interested in print <<<HTML...HTML; part..?

Based on this page:
http://webcheatsheet.com/php/dynamic_image_generation.php
The following seems to operate/run, but, although can't 'see' if the image
looks right, the windows explorer image preview status bar seems to reckon
there's an issue with it, and paint refuses to open the image file..?
<?php
//Send a generated image to the browser
create_image();
exit();
function create_image()
{
//Let's generate a totally random string using md5
$md5 = md5(rand(0,999));
//We don't need a 32 character long string so we trim it down to 5
$pass = substr($md5, 10, 5);
//Set the image width and height
$width = 100;
$height = 20;
//Create the image resource
$image = ImageCreate($width, $height);
//We are making three colors, white, black and gray
$white = ImageColorAllocate($image, 255, 255, 255);
$black = ImageColorAllocate($image, 0, 0, 0);
$grey = ImageColorAllocate($image, 204, 204, 204);
//Make the background black
ImageFill($image, 0, 0, $black);
//Add randomly generated string in white to the image
ImageString($image, 3, 30, 3, $pass, $white);
//Throw in some lines to make it a little bit harder for any bots to break
ImageRectangle($image,0,0,$width-1,$height-1,$grey);
imageline($image, 0, $height/2, $width, $height/2, $grey);
imageline($image, $width/2, 0, $width/2, $height, $grey);
//send it as an attachment
header('Content-Disposition: attachment; filename="dynamic.jpg"');
//Tell the browser what kind of file is come in
header("Content-Type: image/jpeg");
//Output the newly created image in jpeg format
ImageJpeg($image);
//Free up resources
ImageDestroy($image);
}
?>
Also tried rather using ImageCreateFromPNG() and ImageCreateFromJPEG functions
to just load an image from an existing file, and then output it to the browser,
but same issue:
<?php
//Send a generated image to the browser
create_image();
exit();
function create_image()
{
//Create the image resource
$image = ImageCreateFromJPEG("./images/it490.jpg");
//send it as an attachment
header('Content-Disposition: attachment; filename="dynamic.jpg"');
//Tell the browser what kind of file is come in
header("Content-Type: image/jpeg");
//Output the newly created image in jpeg format
ImageJpeg($image);
//Free up resources
ImageDestroy($image);
}
?>
Same thing in terms of image file seeming corrupted, while if rename it to
.txt, and then open it in like notepad, it does seem to have binary
data/character jumbled up in it..?
Effectivelfy, I actually want to take some template images, add text to them in
various fonts/layouts, and then effectively place them in PDF files, and have
got some similar code seeming to work already, but wanted a bit more control
over image files, retrieval of dimensions, etc., but here's a sample that seems
to be working already:
http://blindza.co.za/postcards/pdfVersion.php
Just comes down to that if I want to make a bit more of a dynamic use of
different image templates, I might want to do a bit more than just render them,
etc.
Thoughts..?

Sorry if subject line is off-topic/off-subject, but, again, comes down to not
100% sure about what am asking...:)
Either way, along with these sort of wrapper/parent type objects am now meant
to make use of, the naming convention used to refer to them is like the
following:
Security::functionName();
Database::anythingYouLike;
Those could be referring to either a function, a method, or a property, and
think the objects Security and Database are being instantiated in the sort of
page framework/wrapper I am referring to in the top part of a PHP page, but,
not sure exactly how they are defined, if it's a server/naming convention
setting that means they then don't need to specifically make use of the $ sign
before the name of these objects, whether it's to do with them having being
included/instantiated once off, globally, etc., etc., and the issue with trying
to investigate something like this by searching around the 'net is that certain
search terms aren't the best when it comes to searching around google for
things like this...LOL!
What am trying to put together right about now are my own sort of dummy
versions of these objects, so that can do a bit more testing/trying out code on
my side before uploading pages to server, etc., but anyway.
Thoughts, etc.?
TIA
