[PHP] PHP CLI setting cooked terminal mode
Hi,
I am running a PHP script at the command line and piping the output through
less:
./myScript | less
Since less is an interactive program it puts the terminal into 'raw' mode so
that it can read characters one at a time. However, when I do the above I find
that the commands that I type to less are echoed back to me and not acted on
until I type . This is not as it should be.
The sript is not doing anything really clever, just looking at a few files and
printing out directory contents, time stamps, ...
If I run the script under strace I see:
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo
...}) = 0
ioctl(0, SNDCTL_TMR_STOP or TCSETSW, {B38400 opost isig icanon echo ...}) = 0
I can get it to not do this by connect stdout to /dev/null:
./myScript > /dev/null | less
another way of getting it to work is (and this shows that it really is PHP that
is messing the tty modes):
./myScript > /dev/null | (sleep 10;less)
However: PHP should not set the terminal to cooked mode in the first place
Is there any way in which I can get PHP to not do this ?
TIA
I am running PHP 5.3.3 on CentOS 6.

I remember being faced with spaghetti code 35 odd years ago - yes, horrible. But what do we mean by ''spaghetti code'' ? I remember code where every 3rd statement was some form of GOTO - yuck! One very desirable feature of code is that it be clear, ie: lucid, able to be understood by others. Too many GOTO statements and it is hard. However: a few GOTOs can make things clearer. Think of a function that can fail in several different places (eg data validation, ...). But it is reading a file which needs to be closed before the function returns. I have seen code where some $IsError variable is tested in many places to see if things should be done. That is just as bad as lots of GOTO -- often when having to write something like that I will have a GOTO (in several places) to the bottom of the function that closes the file and returns failure. That is much clearer than extra variables. If I survey my code I find that I use one GOTO in about 4,000 lines of code - that I do not find excessive. There are, however, people who consider any GOTO as communion with the devil. IMHO: not so - if used sparingly. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.

I have solved it. The problem is basically one of ensuring that properties are
the same
value when accessed via the parent or child class ... be that to get or set a
value.
So I solved the problem by making the properties in the child class references
to the
ones in the parent class.
Methods are not a problem - inheritance just works fine.
To do this, pass the instance of the parent class to the child class
constructor and use
a reflection class to determine the properties in the parent class. This will
not work
properly if the child class overrides a property of the parent class ... this
does not
worry me.
class Screen {
public $screen;
}
class Form extends Screen {
function __construct(&$s) {
$sr = new ReflectionClass($s);
foreach($sr->getProperties(ReflectionProperty::IS_PUBLIC |
ReflectionProperty::IS_PROTECTED) as $p)
$this->{$p->name} = &$s->{$p->name};
}
}
$s = new Screen();
$s->AddJsVar('Date', '15 Oct 2011');
$f1 = new Form($s);
$f1->screen = 'something'; // this assigns the property in $s.
Comments ?

[PHP] Extending an instantiated class
Well, that is what I think that I need. Please let me explain what I am trying
to do
and tell me how to do it or a better way of doing it.
I have an application where a Screen (web page) may contain several Forms. The
Forms
will want to access properties, etc, from their Screen. So what I want is to do
something like:
class Screen {
private $JavascriptVars = array();
function AddJsVar($name, $val) {
$this->JavascriptVars[$name] = $val;
}
}
class Form extends Screen {
public $screen; // Could set to a class Screen
function DefineForm($fName)
.
}
$s = new Screen();
$s->AddJsVar('Date', '15 Oct 2011');
$f1 = new Form($s);
$f1->DefineForm('search');
$f1->AddJsVar('CompanyName', 'IBM');
$f2 = new Form($s);
$f2->DefineForm('login');
$f2->AddJsVar('Error', 'Login failed');
The trouble is that $f1->AddJsVar() will fail, class extention seems not
designed to work like that.
I could make it work by either:
1) $f1->screen->AddJsVar() --- but I would rather avoid the extra '->screen'.
2) Use of a __call() in class Form -- but that makes things slower.
Any help gratefully received.
I think that to do what I want PHP would need a syntax like:
$f2 = new $s Form();
or
$f2 = $s->new Form();

[PHP] Default mode -- Output buffering ??
I recently upgraded from RedHat 9 supplied 4.1.2 to from_the_net 4.3.2. I am running the command line version (#!/usr/bin/php) as a .cgi rather than directly in apache as a module (with a .php suffix). What I find is that the first line after #!/usr/bin/php needs to be: Content-type: text/html This used to be generated automatically, and still is in apache module version. The whole thing acts differently, phpinfo() generates text output and not HTML. It seems as if the /usr/bin/php has decided that it is not generating web output any more -- for some reason. Is there a build/configure option that I can set to get the original behaviour or a command line switch to specify 'html on' or something ? I have looked but cannot find anything.

No, the reason that I want to do it is for the same reason that sscanf() does it -- I
want
to change the values of the variables that are passed to it.

[PHP] Call by reference to function arguments
Hi,
I want to write a function (as I have written in several other languages) that
obtains it's arguments dynamically (using func_get_arg()) and then assigns to that
argument. Think of the way that scanf() works -- that sort of thing.
I have distilled what I want to do in the code below. foo adds 1 to all of it's
arguments.
function foo () {
$count = func_num_args();
for($i = 0; $i <= $count; $i++) {
$var = func_get_arg($i);
// The following line should do it, but throws a syntax error
&$var = $var + 1;
}
}
$a = '1';
$b = '2';
$c = '3';
foo($a, $b, $c);
What I am doing is quite different than the above (and more complex), but I will be
able
to achieve what I want if I can get the above to work.
