One more thing:
gdb doesn't do a damned thing for debugging PHP scripts. Look for the
errors and warnings output to the browser. (or tty if you're using
/usr/bin/php).

I don't want to run a script from stdin, I want to retrieve user input
from the keyboard. What the heck are you smoking?

No stream_set_blocking() is the correct function. The others are
deprecated because they are less generic for streams:
This function was previously called as set_socket_blocking()
and later socket_set_blocking() but this usage is deprecated.

This is not what I want, I want individual keystrokes as they come in
form the keyboard. I'm quite sure I know what I'm doing.

Infinite loop, shmoop, the script ran for less than a second. Long
enough for $count to get as high as 2000 tops. I've run many, MANY
scripts as CGI shell script, and never has it bailed from an infinite
loop successfully in less than a second.

Thanks for the lesson, I'll be sure to pretend I didn't know what CGI
is. BTW, if I were a newbie at PHP, your message would make me never
want to make another post. Even in the event you are correct, such a
pathetic response is no way to treat those of lesser knowledge. Now go
read the docs, and learn some more before trying to tell me what's what.

Rob.

Oh you had to tie another on on. I guess I look really stupid. Hmmm
maybe I forgot to run gdb on the PHP binary instead of on the script. Oh
yes, that's got to be it. I ran gdb on the script, and once again I'm
stupid. Now I'm off to say a prayer that you don't inundate me with more
crap.

I believe this is not needed, stdin is nonblocking all the time.

this will never exit until php runs out of memory, and most likely
will lead to unexpected results.

My original test script didn't set the blocking state to non blocking. I
determined from that that stdin is initally in a blocking state. Since I
typed several characters and none where printed till I hit enter.

Yeah, it was just a test script. But still, if the memory had been
exhausted, it wouldn't be in under a second, and I'd get a core dump
like I usually do when I have a runaway recursive function.

I find your responses to my e-mails quite humorous. Upon review --
aside from a single WTF -- I don't think I was condescending in any way
shape or form. I was just trying to offer help.
After reading about wrappers, I find it doubly humorous that you didn't
just disregard my e-mail when I asked you why you were using "php://".
It's not like I said: "php://" isn't a valid protocol. "http://"; and
"ftp://"; are all PHP supports. I just said "Why are you using php://"
below?
And I also qualified my statements about fsockopen() and
set_stream_blocking by saying "I seem to remember" and "If I remember
correctly". And, yes, in PHP 3.0 or whatever it was that was true.
Hence the "if I remember".
So, it would seem to me that as soon as you got to the WTF you should
have said, "This guy thinks I am a noob". And at that point you should
have just said "thanks but you're wrong".
And, just for the record, you never explicitly stated that you needed a
reason to read in only one character at a time. You just sent a bunch
of code down the pipe. So it seems quite natural to assume you're just
making a noobish mistake -- reading a char at a time when a string will
do.
Anyways, you are running an infinite loop and I don't quite see how this
is exiting:
while (1)
{
if ()
else
}
But, hey, more power to you if you've gotten to the level where you
don't understand why people who don't understand some esoteric function
are such muppets.
BTW: If you insist on keeping up with the flamethrowers kindly e-mail me
off list so as not to bother others on the listserv.

How are you calling this script? I'm not sure how cgi will handle
fread <stdin>
With a traditional CGI script <stdin> is what is read on POST data
from a form, and php takes care of this.
That is where my confusion is now.

I'm calling it as "php -qC foo.php". The fread() should work since it
works on input when I don't have stdin in non-blocking mode. Perhaps
it's a bug. I took a look at the doc on streams again, and it uses
php://input as the POST stream. Maybe it's a bug.
Cheers,
Rob.

The particular shape of your help was non newbie friendly. I think that,
combined with your incorrect assessments made it all the more annoying.
And yes, "WTF" and "you really need to read the documentation" played a
key part also since they were quite condescending, and inappropriate
given your incorrect answers and knowledge of functionality.

Actually at that point I thought, "this guy thinks I'm an noob" and he's
being an arse about it. That's no way to treat noobs that post
appropriate questions.

I certainly explained quite well what the problem was. And as you
assumed I was making a noobish mistake and sent a scathing response to
my problem, I also assumed you were an ass, and needed some kind of
clarification.

YES, this is the original question. Why is it exiting. To which you gave
me a whole set of unrequested answers that weren't even on the topic of
my post.

If you don't understand the function, then why are you posting answers
as though you do? Someone asks me about quantum physics, I don't pretend
to know and confuse the whole issue.

Yes, if you reply I'll be sure to take the next one off list, but since
you made this public, I'm sure readers would love to see the backdraft.
The above statement is actually an underhanded attempt to get the last
public word while preventing me from a public response. If you were so
keen to have it off the list, then this email I'm responding to, should
have been off-list itself.
Cheers,
Rob.

File a bug report. stream_set_blocking() started to work for files only
since version 4.3, so it is likely full of bugs. Actualy, using cli php
4.3.2 I got this results some weird results. Your version run infinitely
but changing echo 'Fooo!'."\n"; to echo 'Fooo!'; (removing newline)
resulted in the same behavior as you experienced. fread did not return
false even if no key was pressed, only empty string but this might be
correct, i don't know. Both fgetc and fgets did return false.

Walk through your $_COOKIE array and expire each one:

Hello, I have an intresting problem: I want to let users upload sourcecode
and then compile it using my cygwin gcc... But one thing at a time... I
can't get that gcc to execute...
shell_exec("gcc temp.c"); # Doesn't work as that will use MinGW
shell_exec("D:\\cygwin\\bin\\gcc.exe temp.c"); /* Gives some error about dll
stuff (procedure not found I think)*/
So my next though was to open "bash.exe --login -I" and fwrite the
commands... But that still tries to use the mingw compiler it seems...Guess
there's some environiment problem... So I figured I could use virtual() to a
cgi script with this as first line:
#!D:/cygwin/bin/perl
and then use the perl open(), with |/cygdrive/d/bin/gcc.exe temp.c as
argument... Seems like it executes the right compiler then, but then I get
millions of errors caused by *.h can't be opened (yes, the source tries to
include them), so I though about passing -B /usr/include to it... But those
errors still appear... Also, it feels somewhat bad to use virtual() to call
perl scripts, so I was wondering if you ppl have some nice idea on how I
would do it?
Paths:
Cygwin: d:\cygwin
PHP: C:\PHP (4.3.3, zip from php.net, installed as Apache 1.3.28 module)
Apache: D:\Apache (installed using .msi package, as service)

Hi,
I have been trying to do this for weeks but i just cant figure this out. I have
categories that have subcategories and i want to insert them into database. My table
looks like this: cat_id, parent_id and cat_name.
Let's say i wanna insert a subcategory that is associated with its parent category.
For example
ParentCat 1
ParentCat 1 > ItsSubCat 1
ParentCat 1 > ItsSubCat 2
ParentCat 1 > ItsSubCat 3
ParentCat 1 > ItsSubCat 4
ParentCat 2
ParentCat 2 > ItsSubCat 1
and so on ...
I don't know how to create the script that inserts any subcategory(in this case let's
say ItsSubCat 3) in its parent category.
Please, can someone help me
thanks

I'd use the parent category id as a hidden field in the form when adding a
sub category.
Here is a complete script that contains all the code you would need:

If I understand your situatoin, I would create two tables:
categories (category_id, category_name)
subcategories (subcategory_id, category_id, subcategory_name)
Then, in your PHP script, have the user select the category and enter
the subcategory name. The SQL INSERT would then be
INSERT INTO subcategories (category_id, subcategory_name) VALUES
($cat_id, '$subcat_name');

I need the following replace function:
Replace all line breaks to <br> but not if a line break comes after an </h1>
or </h2> or .... </hx>
Currently I use this preg_replace but it's not good enough for all
situations.
$text = preg_replace("/([^\<][^\/][^h][^1-9].{1})\r\n/","\\1<br />",$text);
????
Thanks

$arr = array("/([^\<][^\/][^h][^1-6].{1}[^\>])\r\n/",
"/([^\<][^\/][^h][^1-6].{1}[^\>])\r/",
"/([^\<][^\/][^h][^1-6].{1}[^\>])\n/",
);
$text = preg_replace($arr,"\\1<br />",$text);
you might try this and see how well it works.

Hi Jim ,
The problem with your proposition is that the preg_replace do not replace
</h1>\r\n to </h1><br />
thats good,
but also not this:
testh4>\r\n
and thats not what I expect from.

Hey all.
I'm running a script from the command-line php interpreter as follows:
(thanks to D. Souza for lead)
$text = `usr/local/bin/php /path/to/my/php/page.php`;
within the read file I want to enable sessions, so I session_start() at the
top of the page:
<?
session_start();
?>
<?
code to execute here.......
?>
Regardless of how I mess around with placement of session_start(), I get a
"Headers already sent".
Why? Nothing has been output to the browser within the read file!
Furthermore, if I create a test page with just:
<?$text = `usr/local/bin/php /path/to/my/php/page.php`;?>
Still receive "Headers already sent".
My eyes are completely fried -- anyone feel like saving my vision?
