It seems to me that PHPGTK[1] is dead; there is, however, wxPHP[2],
which seems to be actively developed.

What happens when you store a string (say, user input) with more than
1023 bytes in buf? Oh, well, of course you won't--good luck.

As a tool for C avoidance, PHP is a bit of a johnny-come-lately.
If that's all you're really interested in, then there are plenty of
more well established options with whatever bells and whistles you're
interested in.

C vs. PHP is just such a weird dichotomy because pure C is so
ancient and PHP is kind of not (and thus somewhat redundant).

On the other hand, PHP has gained itself a reputation for being
the modern day equivalent of Sendmail or BIND in terms of being a
security disaster.

That's a false dichotomy there: C or PHP.

I make sure I don't.
strncpy...

If I really dont know, well then calculate first and malloc.

But modern machines have so MUCH ram its not really worth bothering
about allocating huge stack buffers..

Is "ex of the library" a typo?

Anyway, it still seems odd. I don't know what "its easier to manipulate
at the raw level" means, but if using C's string functions are, for you,
easier than writing PHP's almost identical string functions, so be it.
I can live with one more mystery in my life.

No, indeed. Maybe you perspective comes from use-case in which either
static or automatic arrays of fixed size are all you need.

Well, I never saw that coming. You must be one of the few experienced C
programmers to consider strncpy to be a solution for anything!

....but then memory management is not a simple as a declaration (which is
where this started). In PHP you need neither.

I mean you don't need to use library stuff to manipulate strings in c.

well there ya go.

IF I have a string too long for my buffers something has probably
already gone wrong.

And Id rather not push the system into swap - easier to say 'hey buffer
overflow' and abort.

With PHP, throw it too big a string and weirdness happens as it eats
into memory.



And you still need to do things like mysqli_free() to clear down data
structures.

Inconsistent.

Then I don't see how you can possibly object to a Bourne-compatible

Anyone who thinks "C" is "the language that fits everything" doesn't
know much about programming.

If "C" were so great, why are there so many other languages?

Ben, you're arguing with an idiot. TNP has proven multiple times here
he's neither a programmer nor the EE he claims to be.

Why do you think he's afraid to use his real name?

REXX is a good scripting language for many things. I wrote a lot of
REXX scripts when I was working for IBM. Much easier than doing the
same thing in compiled languages such as C.

Even after leaving IBM I used it quite extensively on OS/2. But it is
one of the many languages I unfortunately have not kept up on over the
years.

Some folks are trying to make a living by writing software. As such
they may tend toward the proprietary side of things. They need to
choose a language that their corporate successors will be able to
support. They need to choose a language in which they can get the job
done on time. Their software needs to cater to the perceived user
demographic. There are a lot of demands, sometimes conflicting demands,
they have to resolve. That situation tends, at least in my experience,
to be very constricting, one could almost say enslaving.

There is however another situation, another point of view. Some of us
have done the "employed as a programmer" thing and survived to lick our
wounds and look around. We can do whatever we choose, however we like,
and if nobody else likes it that's fine, it won't change our standard of
living.

I'm sure there are even more points of view, but the second one is where
I'm coming from. As such, I tend to look at things somewhat differently
than many/most. For example, I don't want to have to write different
code for a web-app versus a local-app, and I don't want to have to write
different code for an X-based app as opposed to an app that will run
without an active X session. I could write assembler but long ago I got
tired of porting code from architecture to architecture, I could write C
or C++ but there are only a relative few kinds of code that require
enough performance and precision to justify putting up with the syntax
and limitations of those languages.

One of the things I learned about software a long time ago is that
there's no single answer, some answers are broken and others not, some
work better or worse than others in some ways, but it isn't a YES/NO
question.

I think that's mostly because of builtin session support and its
tendency to be used for mySQL queries that occur clear-text in the url.

You mean, kind of like bash is enforced, by being embedded nearly
everywhere from the init system upward?

The nice thing about FOSS is that nothing can truly be enforced when the
source code is available, it can only be enforced within particular
implementations that one can choose.

It is? I believe Debian switched to dash for the init system a long time
ago.

And you can obviously install any shell you want. Though it is kind of
difficult to avoid adding bashisms to your scripts. :-)

That is not the language fault but the "programmer". Some frameworks
are just garbage and the bozo factor is language independent. Some of
the first wide spread SQL injections occurred with ASP.

I have to disagree here. Languages are neither secure nor insecure.
Programs are, though.

I think it's more because there are too many people like TNP who call
themselves "programmers" but have no business being near a computer.
PHP is a relatively easy language to learn, but like any language, you
have to know what you're doing to write secure code. Too many people
stop learning before they get to that point.

That's a great part of what quality control and testing is about - not
only feeding the code good input to ensure it responds correctly, but
also feeding it bad input to ensure the code rejects it properly.

But way too many people only check responses to "good" data, and don't
ensure "bad" data is properly rejected. The result is things like SQL
injection and other security issues.

It isn't enforced if you can use something else. It can be
strongly encouraged, however.

white program the reads a text file and swaps every pair of lines and writes
a new file.

so

one
two
three
four


becomes


two
one
four
three





design it to work on any text file.




including files with lines larger than RAM + swap.




if it must work, it's easier in C.

And just how realistic is this? Anyone can come up with an example that
highlights the advantages (or disadvantages) of a particular language.
Your "test" is pretty worthless.

And BTW - I could easily do this in PHP, JAVA and even BASIC just as
easily (in some cases even more so) than in C.

"if you set it up OK"

Well that's the problem right there. Sendmail was/is a complex and powerful
beast with a large number of features that were irrelevant to people 10 or 15
years ago. Nevermind now. It was overkill in most use cases and it's flexibility
a source of problems.

Something simpler and better tailored is less likely to be set up wrong.

The problem is that lots of people aren't. Then they distribute
their work widely to people in no position to clean up after them.

I'd go:

function write_line($fin, $fout)
{
while (($c = fgetc($fin)) !== false && fputs($fout, $c) && $c != "\n");
return $c !== false;
}

function skip_line($fin, $fout)
{
while (($c = fgetc($fin)) !== false && $c != "\n");
return $c !== false;
}

function write_swapped_lines($fin, $fout)
{
while (write_swapped_pair($fin, $fout));
}

the behaviour with an odd number of lines, and when then last line is
not properly terminated, was not given so I took the easiest option!

This is not much more than a translation of what I'd do in C, which in a
way was my point.

The main difference is exchanging the test for EOF to false which takes
a little care (!== rather than !=), but then testing for EOF in C takes
case (you must use the right type variable). I don't think this is a
counter-example, but it's possible I missed the point your were making.

Yes, I agree, and thought that was obvious; sorry I was unclear.

Read 2 lines, swap, write 2 lines to output file, rinse & repeat, what's
the big deal? (Maybe I'm not getting it, I *am* feeling kind of stupid
this morning.)

Whatever for? You need enough "disk" space to contain the input file
and the output file, you need enough memory to contain the two largest
contiguous records and the code to read-2-(swap-2)-write-2. Whether the
swap involves actual data movement or not is a nit, it boils down to a
file-copy 2 lines at a time. (Wouldn't surprise me if the "cp" command
has some option for this kind of thing along with the rest of the
kitchen sink... or is that "tar" that I'm thinking of...)

Unless of course I'm missing something, I'm feeling stupider with each
post about this exercise that I read. <g>

Sure. I haven't looked at a make file in upwards of a decade but the
last time I looked at one it looked kinda like script code.

its where you put the lines that wont fit in even virtual memory..


And I think he is making a point.

When the standard tools and assumptions of the language let you down, C
will get you the solution where PHP will not.

but in the case specified, you dont have that space.

"*lines* larger than RAM + swap" is the key.

you need to essentially read through the input file and tag where the
line begins and ends are.

THEN start reading it sequentially from the tag marks and assembling the
output a few megabytes at a time

i.e. you will end up wit at worst enough storage needed to hold an array
of 'line start and end' offsets in the original file.

Or if space is REALLY tight you do it the way COBOL used to do things.
Yuu scan the file to the first line end and then write thet second line
out, too the new file, then store that location as line 3, and write
line one to the tail of file 2, and so on

The point is that's fairly trivial with C. It doesn't ENFORCE a
particular way of dealing with files on you.

And C with a good library can be really high level too.

BUT if that doesn't work for you, no problem in going near to the
hardware either.

What is “the init system”? My Debian GNU/Linux installations all use bash
(since about 10 years), I am not aware that I had to install anything for
that. In fact, I had to install dash in order to try it.

As they are in many cases not bashisms at all, but cshisms and kshisms.
