Dear PHP Gurus,
I would like to Eliminate the 3 UTF-8 BOM enforced on my returned BLOB:
The PHP server adds utf-8 BOM (UTF-8 Byte Order Mark - in the beginning of
UTF-8 files) which
consists of three bytes: EF BB BF.
The Mobile App served by the server Does not need that. How can I eliminate
it??
Thanks.
UTF-8 Byte Order Mark – BOM:

Can you show us the PHP script that DOES output the BOM?
Normally, PHP doesn't do this automatically (AFAIK). The main reason
being is that it is often the case that the BOM appears in the source
code file before the <?php opening tag, so would block headers
(session cookie for example).
If a BOM is being issued by PHP, it is being done programmatically, or
is being missed due to the initial source code file having the BOM
set.
See http://docs.php.net/manual/en/function.session-start.php#102431,
http://docs.php.net/manual/en/function.header.php#95864, etc.
Now. Having said all of that, you may find you are using some sort of
output buffering and that is setting the BOM after the headers are
sent.
But, as it stands, PHP will not be generating the BOM for you.

Hi Richard,
Thanks.
Indeed, that is the case - I've included a code that has UTF-8 string contants
-so I guess the PHP
parser set the UTF-8 mode to ON so that the returned string to the client has
the UTF-8 BOM.
It is not a big issue as the mobile app guys aware of this and make the proper
3 bytes offset.
Anyhow I was looking for a service to control that behaviour.
Thanks
Eli

No. The parser does not _ADD_ the BOM.
The bom already exists in your source code. Nothing to do with PHP.
The file you included that has the UTF-8 constants has the BOM.
You need to edit that file and remove the BOM. The actions you need to
take will depend upon your editor.

To be a bit more specific...
The BOM is the 3 bytes you correctly identified earlier.
Most editors won't show these when you edit the files.
But, for the sake of argument, let's just pretend they are visible and
look like ...
#@&
In the php script that contains some UTF-8 constants, the file would
look like ...
#@&<php
echo '￦'; // The Fullwidth Won sign.
?>
As PHP will only actually parse the content between <?php and ?>, the
#@& string (the BOM) is simply sent straight through to the web server
-> the client with no interruption.
Now, if your code was ...
#@&<php
session_start();
?>
you would see the headers already sent error message, as the BOM tells
the webserver that data is now being received and to send any headers
it already has.
So when the session_start() wants to send the session cookie (which is
done as a HTTP Header), PHP already knows some content has gone (the
BOM) and reports the error.
To iterate, PHP is NOT generating the BOM. You already did that in
your code. Well, the editor did it for you.
Ideally, you want to turn off the BOM in your editor.

Thanks Richard,
Do you know a technique to mirror all the echo strings into a file for
debugging ?

Hi Richard,
Thanks.
I've already got a solution to simply use Notes++ and save the PHP script
with Save As encoding set to ANSI (It was UTF-8 indeed that creates the BOM...).
Thanks again

Hmmm. You really want to save the code as UTF-8 without BOM.
What is the editor? The references for Notes++ I can find is for a
post-it notes app.

You are suppressing errors (at least based upon the code you've supplied).
Change ...
error_reporting(1); // Will only report E_ERROR - Fatal run-time
errors. These indicate errors that can not be recovered from, such as
a memory allocation problem. Execution of the script is halted.
to
error_reporting(-1); // Shows everything. The code you've supplied is
missing the values for the $value_from and $value_to.

That should work - what is not happening that you expect to happen, or the

Stuart:
Interesting and nice idea (your snippets). I'm sure it's easier for
you to read, but my first thought about V() is huh? In truth, it
would take me a while to get used to it and if I came across it in
someone else's code I would find it more confusing than a ternary
operator.
Questions:
1. Why "V"? Does that stand for Variable?
2. Why the "()" in:
$var = (isset($_GET['var']) ? $_GET['var']) : '');
Why not?
$var = isset($_GET['var']) ? $_GET['var']) : '';
3. Are the "Ramblings of a random software engineer" the "Ramblings
of a random-software engineer" or the "Ramblings of a random
software-engineer" ?

Then calling it ifsetor would probably work better.

Putting () around ternary's is a "best practise".
<?php
echo 'Are we ready to go? ', isset($go) ? 'Yes we are.' : 'No we are
not.', ' Ready state completed', PHP_EOL;
$go = true;
echo 'Are we ready to go? ', isset($go) ? 'Yes we are.' : 'No we are
not.', ' Ready state completed', PHP_EOL;
?>
vs.
<?php
echo 'Are we ready to go? ' . isset($go) ? 'Yes we are.' : 'No we are
not.' . ' Ready state completed' . PHP_EOL;
$go = true;
echo 'Are we ready to go? ' . isset($go) ? 'Yes we are.' : 'No we are
not.' . ' Ready state completed' . PHP_EOL;
?>
vs.
<?php
echo 'Are we ready to go? ' . (isset($go) ? 'Yes we are.' : 'No we are
not.') . ' Ready state completed' . PHP_EOL;
$go = true;
echo 'Are we ready to go? ' . (isset($go) ? 'Yes we are.' : 'No we are
not.') . ' Ready state completed' . PHP_EOL;
?>
Don't run them just yet.
Can you quickly and easily see the output?

Argg! :-)
$ready = 'Are we ready to go? ';
$yes = 'Yes we are.';
$no = 'No we are not.'
echo($ready);
echo(isset($go) ? $yes : $no);

Tedd,
echo is a construct and the () are not required. ;-p
The purpose of the code was not to demonstrate any particular coding
style, but what happens if you use a ternary without () around it.
Without running the code, can you say what the output will be in the 3 examples?
