I used eclispe, but I'm using netbeans now. Runs on win and linux.
Just to edit a file here and there I use kate on linux (many text
editors have highlighting/folding on linux) and notepad++ when I have to
be on windows.

I use Kate on Linux, works like N++, but has some extra features, like
built in command line console

<shudder>
Eclipse + PDT is my recommendation FWIW...
GM
<shudder> is right and it appears that they didn't get their Mac
option running by fall of 2008.
I use Eclipse for Java, but have not used it for php much. I need not
only an editor but also a file manager. Everything I've see from
Eclipse (thus far) is that you develop locally and use something else
to upload and keep track of your file remotely -- but I could be
wrong.
Thus far, I use GoLive, but sometimes that sucker craters and it's a
bitch to get everything back the way it was. It has zero tolerance
for files that might have a problem.

Hello Guys,
I use SOAP calls to make web service requests.I have a class that does
webservice calls to various wsdls. So my question is about try catch blocks.
so my method looks like this:
private function method($cookie){
//Define Client
try{
// Check if WSDL exists
if(!...@file_get_contents($this->WSDL)) {
throw new SoapFault('Server', 'No WSDL found at ' .
$this->WSDL);
}
$client = new SoapClient($this->WSDL, array(
'exceptions' => 1,
'encoding' => "UTF-8",
'connection_timeout' => 60
));
}catch(SoapFault $fault){
// Error if the WSDL is not available or new client cannot be made
//log errror
}
//Define Input Array
$input = array();
$input['cookie'] = $cookie;
//Make the call
try{
$result = $client->function($input);// Make the Call
return $result;
}catch(SoapFault $fault){
//log error
}
}
How is it possible for me to *remove *these 2 try and catch blocks from this
method and just throw exceptions, but do a try and catch in the business
logic.
So basically I might have different functions in business logic area that
might call the same method and I do error logging there itself instead
directly in the method?
Thanks,
V

In another thread (which I mercifully declined to highjack), someone
cited:

And I read this:
Both '$foo =& new StdClass()' and 'function &foo' will now raise an
E_STRICT error.
I don't use this much, but where I do, it's vital. Typically, I use it
to ensure a single copy of the $config for an application, as:
function &get_config() ...
and/or:
$cfg =& get_config();
If this is going away, how do you return things by reference, so as to
ensure a single copy of something (yes, I know the singleton pattern can
be used; I do use it as well; it's more complicated)?

PHP5 made it so that objects are always passed by handle. When assigned
or passed as a parameter a copy of the object handle is passed (rather
than a copy of the object itself a la PHP4). Given this, you are in many
ways passing around an implicit reference. It's not exactly a reference,
since there are subtle differences, but the object won't be cloned as it
is in PHP4 using this method. So singletons will work as expected. For
example:
<?php
$a = new StdClass();
$a->a = 'a';
$b = new StdClass();
$b->b = 'b';
$c = new StdClass();
$c->c = 'c';
$d = new StdClass();
$d->d = 'd';
$x = $a;
$x->x1 = 'x1';
$x = $b;
$x->x2 = 'x2';
$y = &$c;
$y->y1 = 'y1';
$y = $d;
$y->y2 = 'y2';
echo "a:\n";
print_r( $a );
echo "b:\n";
print_r( $b );
echo "c:\n";
print_r( $c );
echo "d:\n";
print_r( $d );
echo "x:\n";
print_r( $x );
echo "y:\n";
print_r( $y );
?>
You will get the following output in PHP5:
a:
stdClass Object
(
[a] => a
[x1] => x1
)
b:
stdClass Object
(
[b] => b
[x2] => x2
)
c:
stdClass Object
(
[d] => d
[y2] => y2
)
d:
stdClass Object
(
[d] => d
[y2] => y2
)
x:
stdClass Object
(
[b] => b
[x2] => x2
)
y:
stdClass Object
(
[d] => d
[y2] => y2
)
The difference between references and handles in PHP5 is exemplified
by the output of $a versus the output of $c. In the case of $c because
we assign a reference for $c to $y, then subsequently we assign $d by
value, we essentially completely replace the object $c with $d.
Whereas when we assigned $a by value to $x, then subsequently assigned
$b by value to $x only the handle value was changed.
Cheers,
Rob.

'Twas brillig, and Paul M Foster at 02/05/09 06:07 did gyre and gimble:
If this is going away, how do you return things by reference, so as to
ensure a single copy of something (yes, I know the singleton pattern can
be used; I do use it as well; it's more complicated)?
You'll want to use the Singleton design pattern here.
Let's say you're config object is a class.
Something like this should work very nicely.
class My_Config
{
private function __construct()
{
// Whatever you need to do to load the config
}
public static function getInstance()
{
static $instance = null;
if (null === $instance)
$instance = new self();
return $instance;
}
}
Then in your code whenever you want to get your config object you would
call:
$config = My_Config::getInstance();
You'll only every get one object created due to the private constructor
and which enforces the use of the getInstance() method.
This is a very common design pattern, and is ideally suited to this use
case.

If you don't set the enctype to multipart/form-data in your form, then
only the filename will be uploaded as part of the form. To get the file
size you would have to allow the file to be uploaded, even if only to
the temporary directory.

exactly, why bother with JavaScript literal representation?
the foreach loop was just an alternative to explicit object cast cause you did
not like it .... I though it was more about control over what you want to cast
and what you do not ... in any case, what I said does not change cause in php
you have natural type hint over arrays and these are normally slightly faster
so I do not get why you want objects rather than arrays ...

It's not what I want, I'm not the original poster. Regardless though, it
comes down to the preference of the developer. It can certainly be
simpler to type:
$obj->blah->bleh->bluh;
than to type:
$obj['blah']['bleh']['blug'];

That is so weird... I got "Undefined variable: obj".
