I say this is a logic error. Bugs #54109 and #52397 also mention the
same 

behavior in two other spots of code. 

php_error_docref already handles display_errors configurations... I
don't how 

this would be considered correct/intended 

behavior.. 



Questionable logic: http://svn.php.net/viewvc/php/php-

src/branches/PHP_5_3/ext/standard/html.c?view=markup#l1145



if(!PG(display_errors)) { 

php_error_docref(NULL TSRMLS_CC, E_WARNING, "Invalid multibyte sequence


in argument");

}

I'm afraid this isn't just confusing, but actually punishes people who
do it right by blindsiding them completely.



Scenario:



 * display_errors off

 * an Exception-throwing error handler



As far as I'm informed, this is good practise. (I acknowledge I may be
misinformed.)



However, due to this behaviour, you suddenly get application crashes in
production without that anyone really 

understands why the code snippet is suddenly a culprit. 'But we tested
it with broken UTF-8, why are -we- just 

getting empty strings? And the documentation says that's what we should
be expecting...'

Yeah, you're not alone; but live and learn, I guess? :)

Well, from my experience, people who deliberately turn display_errors on
for development except their feedback in 

the browser window [*unless* they are writing for XHR], not in a log
they may also be running in parallel.



This is especially true if you have a complex application that logs
debug information from several services into one 

file in a compact format - so, unless you're LOOKING for an error, you
won't spot anything. (Total sidenote, I 

honestly wish I could change the log format I have to suffer... but I'm
stuck with it. Gargh.)



If you've been a good developer and read the manual on
htmlspecialchars(), you're not going to expect an error. 

You're going to expect an empty string. Unfortunately currently, nothing
in the documentation reveals that the 

function results in an E_WARNING, either pure-log-only when
display_errors is on, or log and trigger_error()ed when 

display_errors is off.



By the time you find this closed php bug... well, if you're lucky,
you've forced your developers to have a wrapper 

function you can now add a try-catch to - otherwise you can now do a
project-wide search for every call of the 

function. [To be fair, I was fortunately lucky.]



Could this bug please get REOPENED as a documentation bug? I think
adding this behaviour to the documentation would 

help a lot of people confused by it.


[2010-06-14 13:30:05] trueleader at gmx dot de

Why the developer of the language create a workaround for bad configured
servers and/or applications?



If a configuration variable tells that errors are shown on screen then I
think all errors (dependent on reporting level) are shown - and not that
they can be only logged if the configuration variable is turned off.

I think/hope this is not only my opinion.



We just lost some data, because we fill a JS confirm message on a HTML
click event with a string from a PHP language variable. Nobody knows
that we missed
