I have been absolutely unsuccessful in putting PHP tags in a string.
suppose I want my string to be "?> something <?"
?
How on earth is it possible to STOP PHP interpreting that as some
blasted 'escape to outputting text'
??

Ok scrub that.
THIS worked.
$run="something";
$run="?>".$run;
$run= $run."<?";
$run=htmlspecaialchars($run);
echo $run;

<?php echo "?> something <?";
Works as expected. In the browser output you'll see "?> something" since
the browser will interpret the remaining "<?" as the start of a
processing instruction, but when you look at the generated source code,
it's all there as it should be. Perhaps you might want
<?php echo htmlspecialchars( "?> something <?" );
Greetings,
Thomas

Would this do?
<?PHP
for ($loop = 1; $loop <= 30; $loop++)
{
$ic = chr($loop);
$d1 = chr(63).$ic.chr(62);
$d2 = chr(60).$ic.chr(63);
$str = "$d1 something $d2";
echo "char($loop): $str <br>";
}
?>
Looks like chr(5),chr(7),chr(14) and chr(15) work in cli mode as well.

Or even:
echo htmpspecialchars ('?> ' . $something . ' <' . '?php');

Sorry, but I still don't quite see the problem. PHP will happily accept
the above string as what it is: a simple string. It will not try to
interpret the <? or ?> contained within that string (why should it?).

Actually, it's the ?> that is causing the problem. If you attempt to:
echo "?> something <? something else";
in a browser, you get:
?> something
even though view source shows everything to be there. Inserting an
'invisible' character between <? or using htmlspecialchars() which turns
the > < into their html equivalents > < as NP found out shows that
it's a browser issue, not PHP.

Thomas, the problem is with the ability of the poster you are applying to
to comprehend and understand string handling in php, and what his browser
views as an element.
Most of us understood the need to use < and why in html if we wanted a
less than symbol within a few months at most of starting to use html.
Some others will never understand it.
Also, as you have noticed, the failure modes that some people post are
not the failures that occur in the circumstances they describe. When you
see this, you can usually assume that the person concerned does not, to
use a common term, know their arse from their elbow.

the problem isn't having the string, its getting the interpreter to not
interpret any way you have of constructing it.

The problem is of course that you have totally failed to understand the
problem I was in fact having.
It has NOTHING to do with the browser.
The string output was never going anywhere NEAR a browser.
The problem was how to CONSTRUCT a string using PHP, to put in a file or
a database, that contain PHP escape sequences.
Without. PHP interpreting them AS escape sequences.
That is given the string $something, how to make
$new="?>".$something."<?";
without PHP instantly thinking you wanted to print $something on stdout.

Or in this case,.. the person his not bothered to understand the actual
problem being described.

The issue is that the PHP interpreter is defined to be smart enough that
the ?> closing tag should NOT be recognized inside a quoted string the
way you have stated. It is almost certainly some other problem.
Can you post an EXACT COMPLETE example showing the problem and the
output you get (view source on the page)?

I managed to get it to work, as I stated earlier..
This was the final code which works, hopefully not by some versional quirk
$run="?>".$run;
$run= $run."<?";

If that works, then so should your original example... as well as:
$run="?> $something <?";
Can you post an example of what wasn't working with output? And where
the output is going? Cannot duplicate here.

In my setup that produces no output at all.
Mind you php -a doesnt produce any output from
php> echo "this";
either..
Nor even a command prompt
It just sits there...

Ineptocracy
(in-ep-toc’-ra-cy) – a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers.

I guess you all have different default options/settings.
Mine just outputs: echo "this";
as expected, because it isn't processed as PHP, because it is missing <?php
I do need to give end of file before anything is output.
php -a
<?php $run="?> something <";
echo $run;
outputs "?> something <?" just fine, again once the input is closed with end
of file.
and the following produces "?> something <?", once the EOF is received:
php -a
<?php
$saysomething="something";
$run="?> $saysomething <?";
echo $run;
Maybe try "php -n -a" and don't forget EOF as well as the php opening tag.

That doesn't fly here... You seem to be in Interactive Mode not
Interactive Shell, there is a difference.

Well, then how are you 'running' your code? You show a command prompt
above. The interactive shell executes each line as you type it in. I
can't even imagine what your setup is without you telling.

Then get a clue. TNP uses PHP at the command line with:
php -a
He then enters:
echo "this";
at the prompt, and it hangs. There. That wasn't too hard to figure out,
was it.

Then it's something in his configuration that's different to my command
line configuration.

Works the same for me as it did for Tim.
Maybe you hit ctrl-Z (or ctrl-D on linux)?

Nope, I did the following as Tim posted, starting from a shell prompt:
php -a
echo "this";
And what appears on my screen is this:
$ php -a
Interactive shell
php > echo "this";
this
php > exit
$
So if TNPs system is hanging after he enters the 'echo "this";' then my
bet is that it's something he did to his configuration.

Correct. But it seems TNP has the same or at least a similar setup.

What I get in both Windows and Linux is:
C:\>php -a
Interactive mode enabled
echo "this";
Then after doing ctrl-Z (ctrl-D in Linux)
echo "this";
I could check through the php.ini options to see what affects this, but
considering the source of the problem, I really don't care.

You are in 'Interactive Mode', not 'Interactive Shell'. You just
need to type (press enter after each line):
$ php -a
Interactive mode enabled
<?php
echo "?> something <?";
?>
press CTRL-D (or Z maybe)
---
It's a compilation option --with-readline (or lack of) that causes it
to revert to this mode. I don't feel like compiling PHP just to find
out. Give it a go.

It's not hanging, but waiting for proper EOF. But also probably needs
proper starting and ending tags as well.
<?php
echo "?> something <?";
?>
CTRL-D (or Z maybe)

I do believe you need to use proper starting and ending tags. You're
output indicates PHP has simply passed-thru the text you entered. But
yes CTRL-D or Z maybe should be the proper way to 'run' the code in
Interactive *Mode*

I agree with the tags - I've always used them when testing. Here, I was
entering the text exactly as Dennis did, and showing I did NOT get the
results he did.

Not in my setup:
Starting at a command shell, the only things I type are the following 3
lines:
php -a
echo "this";
exit
What appears on my console are the following 7 lines:
$ php -a
Interactive shell
php > echo "this";
this
php > exit
$

Dennis,
You and I have the 'Interactive *SHELL*' and that is the way it is
supposed to work. 'Interactive *MODE* is something different. You can't
pick which one you use at the terminal.
http://php.net/manual/en/features.commandline.interactive.php
"Interactive *MODE* is essentially like running php with stdin as the
file input. You just type code, and when you're done (Ctrl-D), php
executes whatever you typed as if it were a normal PHP (PHTML) file -
hence you start in interactive *mode* with '<?php' in order to execute
code."
http://www.php.net/manual/en/features.commandline.interactive.php#108006
https://bugs.php.net/bug.php?id=60683
It's not a bug, read the history down to the bottom.

I have never configured PHP to use a shell at all.
It is a vanilla debian stable installation.

“php -a” does different things depending on the PHP build options. As it
says there, PHP must be built with readline support for the interactive PHP
shell to be available; otherwise “-a” will read until it receives an EOF
character (Ctrl+*D* on *Unices*, Ctrl+*Z* on *Windows*), and then execute
the program.
Where the built-in PHP shell is not available, like on Debian GNU/Linux,
there is phpsh. However, phpsh's coloring is buggy, so
alias phpsh='phpsh -c'
in e.g. ~/.bashrc, to disable that, is recommended.
