Re: [PHP] message to user after complete POST
hey, if you are just trying to give the user a feedback about the information sent, there is a Global variable for this, and it's the $_POST. When you receive the information on the script you called on the Action atribute of the form, via the $_POST global variable, you will test the information end echo the feedback on that script. Note that, unless you are using ajax (jquery, or any other javascript ajax method), when you post a form, you will be intantly redirected to the action path. then you have nothing to do in the source page. hope you got it. 2013/9/4 iccsi inu...@gmail.com I have a POST form and action itself like following form name=MyForm id=MyForm method=POST action=index.php /form I want to show success message when POST complete or error message if there is any.

Re: [PHP] Static utility class?
Hi, first, sorry for the bad English. Yes, at least, as far as I know, this is the perfect way to do what you want to do. Think like this: when you instanciate a class, you are allocating memory. If you don't need any information stored, then you don't need to allocate memory, right? So, it's is logic to have a class that you will call only one fragment when you need it, rather than load the entire class just for one method. Just be careful to organize your utility methods by by meaning. Don't put a method that make dating stuff and a method that write a random string in the same class. By doing so, you are breaking the object orientation purpose. 2013/9/4 Micky Hulse mickyhulse.li...@gmail.com Hi all! Example code: https://gist.github.com/mhulse/6441525 Goal: I want to have a utility class that contain utility methods which should have the option of being called multiple times on a page. I think my main goal is to avoid having to new things ... I don't really need to create an instance here (there's no need for a constructor in this case). Question: Is the above simple pattern a good way to have a class that calls static methods? To put it another way, is there any reason why I would not want to use the above code? Basically I want to wrap these simple functions in a nice class wrapper and have the ability to call them without having to jump through more hoops than is necessary. Are there any pitfalls to writing a class like this? Or, is this the standard way of writing a simple utility class for this type of situation? Please let me know if I need to clarify my questions. Thanks for your time?

'id' = string '6904' (length=4)

Notice that they're all the same values, although the keys seem right. I
don't understand why that happens because
foreach($this-tmp_results as $k = $v)
Should be changing $v each iteration I'd think.
Honestly, I am baffled as to why those unsets() make no difference. All
I
can think is that the garbage collector doesn't run. But then I had also
tried to force gc() and that still made no difference. *sigh*
I had some other cockamamie idea where I'd use the same tmp_results
array
in
a tricky way to avoid a second array. The concept being I'd add 1
million
to the ['id'] (which we want as the new array key), then unset the
existing
sequential key, then when all done, loop through and shift all the keys
by
1
million thereby they'd be the right index ID. So add one and unset one
immediately after. Clever right? 'cept it too made no difference on
memory.
Same thing is happening as above where the gc() isn't running or
something
is holding all that memory until the end. *sigh*
Then I tried a different way using array_combine() and noticed something
very disturbing.

$g = explode('|', $v['genres']);

You are assigning a reference to $v. In the next iteration of the loop, $v will
be pointing at the next item in the array, as will the reference you're storing
here. With this code I'd expect $new_tmp_results to be an array where the keys
(i.e. the IDs) are correct, but the data in each item matches the data in the
last item from the original array, which appears to be what you describe.
unset($this-tmp_results[$k]);
Doing this for every loop is likely very inefficient. I don't know how the
inner workings of PHP process something like this, but I wouldn't be surprised
if it's allocating a new chunk of memory for a version of the array without
this element. You may find it better to not unset anything until the loop has
finished, at which point you can just unset($this-tmp_results).

I'd appreciate it if you could plug this in and see what your memory usage
reports say. In most cases, trying to control the garbage collection through
the use of references is the worst way to go about optimising your code. In my
code above I'm relying on PHPs copy-on-write feature where data is only
duplicated when assigned if it changes. No unsets, just using scope to mark a
variable as able to be cleaned up.
Where is this result set coming from? You'd save yourself a lot of memory/time
by putting the data in to this format when you read it from the source. For
example, if reading it from MySQL, $this-tmp_results[$row['id']] = $row when
looping around the result set.
Also, is there any reason why you need to process this full set of data in one
go? Can you not break it up in to smaller pieces that won't put as much strain
on resources?

You could save another, relatively small, chunk of memory by crafting your loop
with the rewind, key, current and next methods (look them up to see what they
do). Using those you won't need to make a copy of the array keys as done in the
above line. When you've got the amount of data you're dealing with it may be
worth investing that time.

Then remove that from the string before you explode. Munging arrays is
expensive, both computationally and in terms of memory usage.

Get rid of the temporary variable again - there's no need for it.

If this is going in to a class, and you have control over how it's accessed,

No matter what I tried however it seems that frustratingly just the simple
act of adding a new hash to the array is causing a significant memory jump.
That really blows! Therefore my solution was to not store the $g as ['g'] --
which would seem to be the more efficient way of doing this once and re-use
the array over and over, but instead I am forced to inline rip through and
explode() in three different places of my code.
Consider what you're asking PHP to do. You're taking an element in the middle
of an array structure in memory and asking PHP to make it bigger. What's PHP
going to do? It's going to copy the entire array to a new location in memory
with an additional amount reserved for what you're adding. Note that this is
just a guess - it's entirely possible that PHP manages it's memory better than
that, but I wouldn't count on it.
We get over 30,000 hits per second, and even with lots of caching, 216MB vs
70-96MB is significant and the speed hit is only about 1.5 seconds more per
page.
Here are three distinctly different example pages that exercise different
parts of the code path:

Knowing nothing about your application I'm obviously not in a strong position
to comment, but seven seconds to generate a page would be unacceptable to me
and any of my clients. I'll put money on it being possible to cut that time by
changing your caching strategy. The memory usage is also ridiculous - does a

You could save another, relatively small, chunk of memory by crafting your
loop with the rewind, key, current and next methods (look them up to see
what they do). Using those you won't need to make a copy of the array keys
as done in the above line. When you've got the amount of data you're
dealing
with it may be worth investing that time.
/*
if ($this-tmp_results[$k]['genres'])
{
// rip through each scene's `genres` and
store them as an array since we'll need'em later too
$g = explode('|',
$this-tmp_results[$k]['genres']);
array_pop($g); // there is an extra ''
element due to the final | character. :-\
Then remove that from the string before you explode.
Munging arrays is
expensive, both computationally and in terms of memory usage.
$this-tmp_results[$k]['g'] = $g;
Get rid of the temporary variable again - there's no need for it.
$this-tmp_results[$k]['g'] = explode('|', trim($this-
tmp_results[$k]['genres'], '|'));
Maybe an option. I'll look into trim() the last | off the tmp_results in a
loop at the top. Not sure if changing the variable will have the same effect
as adding one does. Interesting to see...
If this is going in to a class, and you have control over how it's

you have the ability to do this when the value is accessed. This means you

Awesome.
No matter what I tried however it seems that frustratingly just the
simple
act of adding a new hash to the array is causing a significant memory
jump.
That really blows! Therefore my solution was to not store the $g as
['g']
--
which would seem to be the more efficient way of doing this once and re-
use
the array over and over, but instead I am forced to inline rip through
and
explode() in three different places of my code.
Consider what you're asking PHP to do. You're taking an element in the
middle of an array structure in memory and asking PHP to make it bigger.
What's PHP going to do? It's going to copy the entire array to a new
location in memory with an additional amount reserved for what you're
adding. Note that this is just a guess - it's entirely possible that PHP
manages it's memory better than that, but I wouldn't count on it.
We get over 30,000 hits per second, and even with lots of caching, 216MB
vs
70-96MB is significant and the speed hit is only about 1.5 seconds more
per

I do not know what opcache has to do with it, although I suspect that
Piwik is calling itself a lot of times and that opcache is trailing
behind (or something like that).

I'm confused on how a reference works I think.
I have a DB result set in an array I'm looping over. All I simply want
to
do

This is the basic gist of it:
private function _normalize_result_set()
{
foreach($this-tmp_results as $k = $v)
{
$id = $v['id'];
$new_tmp_results[$id] = $v; //2013-08-29 [dv]
using
a
reference here cuts the memory usage in half!
unset($this-tmp_results[$k]);

gc_disable(); // Disable Garbage Collector
}
*/
}
$this-tmp_results = $new_tmp_results;
//var_dump($this-tmp_results); exit;
unset($new_tmp_results);
}
Without using the = reference, my data works great:
$new_tmp_results[$id] = $v;
array (size=79552)
6904 =
array (size=4)
'id' = string '6904' (length=4)
'studio_id' = string '5' (length=1)
'genres' = string '34|' (length=3)
6905 =
array (size=4)
'id' = string '6905' (length=4)
'studio_id' = string '5' (length=1)
'genres' = string '6|37|' (length=5)
However it takes a stupid amount of memory for some unknown reason.
MEMORY USED @START: 262,144 - @END: 42,729,472 = 42,467,328 BYTES
MEMORY PEAK USAGE: 216,530,944 BYTES
When using the reference the memory drastically goes down to what I'd
EXPECT
it to be (and actually the problem I'm trying to solve).
MEMORY USED @START: 262,144 - @END: 6,029,312 = 5,767,168 BYTES
MEMORY PEAK USAGE: 82,051,072 BYTES
However my array is all kinds of wrong:
array (size=79552)
6904 =
array (size=4)
'id' = string '86260' (length=5)
'studio_id' = string '210' (length=3)
'genres' = string '8|9|10|29|58|' (length=13)
6905 =
array (size=4)
'id' = string '86260' (length=5)
'studio_id' = string '210' (length=3)
'genres' = string '8|9|10|29|58|' (length=13)
Notice that they're all the same values, although the keys seem right. I
don't understand why that happens because
foreach($this-tmp_results as $k = $v)
Should be changing $v each iteration I'd think.
Honestly, I am baffled as to why those unsets() make no difference. All
I
can think is that the garbage collector doesn't run. But then I had also
tried to force gc() and that still made no difference. *sigh*
I had some other cockamamie idea where I'd use the same tmp_results
array
in
a tricky way to avoid a second array. The concept being I'd add 1
million
to the ['id'] (which we want as the new array key), then unset the
existing
sequential key, then when all done, loop through and shift all the keys
by
1
million thereby they'd be the right index ID. So add one and unset one
immediately after. Clever right? 'cept it too made no difference on
memory.
Same thing is happening as above where the gc() isn't running or
something
is holding all that memory until the end. *sigh*
Then I tried a different way using array_combine() and noticed something
very disturbing.

private function _normalize_result_set()

$id = $v['id'];
$tmp_keys[] = $id;
if ($v['genres'])
{
$g = explode('|', $v['genres']);
$this-tmp_results[$k]['g'] = $g; //this
causes a
massive spike in memory usage
}
}
//var_dump($tmp_keys, $this-tmp_results); exit;

Without your patience it never would have happened. Also wanted to tell you that I've scrapped it all. Keeping the code for a rainy day of course, but giving up on using it (as well as the basic auth signon process) to use my own 'roll-your-own' code. Since IE insisted on presenting multiple credentials during the signon process it was a futile effort to be doing a signoff.

It's possible that this is an SELinux issue, which adds an extra layer of permissions over files. To see what those permissions are, use the -Z flag for ls. Also, check the SELinux logs (assuming that it's running and it is causing a problem) to see if it brings up anything. It's typically found on RedHat-based distros.

believe the exec and system functions are likely working just fine,
but that

I didn't say you couldn't change it, I said doing so will have no effect on the browser. It's not really confusing so long as you understand how PHP works. Each request is brand new - nothing is retained from previous requests. The two variable you're changing are set by PHP when the request comes in from the browser. The fact you changed them in a previous request is irrelevant because 1) that change was not communicated to the browser in any way, and 2) PHP doesn't retain any data between requests [1].

The $_SESSION array is populated when you call session_start(). It's loaded from some form of storage (files by default) and unserialised in to $_SESSION. When the session is closed, either implicitly by the request ending or by a call to one of the methods that explicitly do it, the contents are serialised to the storage system. Once closed, any changes to $_SESSION will not be stored; it becomes just another superglobal (not that it was ever anything else). -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You don't need to do anything on the server-side. You simply need a JS function
that sends a request to a URL that requires basic auth, with an Authenticate
header that contains an invalid username and password. Then, when your server
responds with a 401 Authentication required (which it should already do for an
invalid request) you can set location.href to whatever URL you want the logged
out user to see.
If you don't know how to make a request from Javascript -- commonly known as an
AJAX request -- then google for it. I'd recommend the jquery library if you
want a very easy way to do it.

Im confused about your mention of contains an invalid username

What you won't get by doing that, however, is anything other than the file name and type, because the kernel is forbidden from executing mtime, ctime, and owner/group queries on the files. In addition, you won't be able to enter the directory (cd). That said, if Ethan is running his Apache server as the user 'ethan' (which isn't mentioned) then it would be fine regardless.

As can be seen, I wish to redirect to the URL autologin.php.

Is it even possible?
If yes, I will be grateful if someone could let me know how to redirect to

No. Sending a 'Location:' header issues an HTTP 301 by default,
which means the browser will follow it using a GET request. If you
can't pass the information from one location to another using sessions
or (less ideally) cookies, you might consider doing a cURL POST
request in the background and passing the session ID back to the
browser, and having it handle it appropriately (read: session
hijack).

as an AJAX request -- then google for it. I'd recommend the jquery
library if you want a very easy way to do it.
-Stuart
I am familiar with an ajax request (xmlhttprequest) and I have a function
ready to call a script to effect this signoff. I just don't know what to
put in that php script I'm calling. From what you just wrote I'm guessing
that my headers as shown previously may be close - Im confused about
your mention of contains an invalid username As you can see from my
sample I don't include such a thing.
For the last time: YOU DO NOT NEED TO MAKE ANY CHANGES SERVER-SIDE.
From the Javascript, request any URL that requires authentication - it
doesn't matter. When you make the AJAX request, pass an Authentication
header that contains an invalid username and password. If you don't know
what I mean by that, please google how HTTP Basic Auth works.
-Stuart
It's not the basic auth that I'm having the issue with - it's the 'header'
thing and understanding what a 401 is doing and how I'm to ignore it. Never
had to play with these things before and this part is all new. Let's face it
- I'm an applications guy, not a systems guy. All this talk of headers and
such is greek to me.
HTTP headers are as important for application guys as they are for systems
guys. I appreciate that this may be new to you, but it's pretty basic knowledge
about how HTTP works.
Basic auth is simple, and you need to understand how it works to understand
what I've been trying to say. Here's how HTTP auth works:
1) Browser hits page.
2) The PHP script knows this page requires HTTP Auth, checks the
PHP_AUTH_[USER|PW] variables but doesn't find anything, so it responds with an
HTTP status of 401 Unauthorised.
3) The browser gets the 401 response and displays the login box.
4) User enters username and password

It's not really confusing so long as you understand how PHP works. Each request
is brand new - nothing is retained from previous requests. The two variable
you're changing are set by PHP when the request comes in from the browser. The
fact you changed them in a previous request is irrelevant because 1) that
change was not communicated to the browser in any way, and 2) PHP doesn't
retain any data between requests [1].
If you've been coding assuming that changes you make to global variables are
retained between requests you must have been having some pretty frustrating
times!
-Stuart
Not really - this is the first time I've had something not work as expected.
That was said with my tongue very much firmly in my cheek, and so is this:
I've been playing with dynamite since I was 4 - hey, it must be a safe,
proper thing to do!
Just because nothing has blown up in your face yet doesn't mean it won't, and
I'm concerned that you might not actually see how important it is to make sure
you're using the tool correctly.
-Stuart
This may very well be the first time with this problem because I haven't tried
anything like this before.
That said - can you give me some pointers on how to do the JS solution? I'm
calling a script that is similar to the one I used to signon. It sends out
something like:
header(WWW-Authenticate: Basic realm=$realm);
header('HTTP/1.0 401 Unauthorized');
echo h3You have entered invalid credentialsbr;
echo Click a href='$return_url' here /a to return to the menu.;
exit();
when it doesn't detect the PHP_AUTH_USER or it is an invalid value.
So - to effect a signoff, what does one do? You said to use an invalid value,
but what do I do with that? How do I ignore the 401? Now I'm getting the
signin dialog and I'm stuck.
You don't need to do anything on the server-side. You simply need a JS function
that sends a request to a URL that requires basic auth, with an Authenticate
header that contains an invalid username and password. Then, when your server
responds with a 401 Authentication required (which it should already do for an
invalid request) you can set location.href to whatever URL you want the logged
out user to see.
If you don't know how to make a request from Javascript -- commonly known as an
AJAX request -- then google for it. I'd recommend the jquery library if you
want a very easy way to do it.

Hi Ethan,
Is there a reason you're using shell commands to achieve the following:
?php
$path = '/var/www/orders.txt';
if( !file_exists( $path ) )
{
if( !touch( $path ) )
{
echo 'Failed to touch file into existence: '.$path.\n;
}
else
{
if( !chmod( $path, 0766 ) )
{
echo 'Failed to update file permissions: '.$path.\n;
}
}
}
?
Also, why are you setting the executable bit on a text file? :)
Cheers,
Rob.

Usually you would pass this around in sessions. If you must however use
post, you can only do so with using some javascript magic. Write a form
with hidden input and auto submit it.

You're replying to me about something someone else asked you.
Please show the output of the directory listing.
Please us ls -la
echo exec('ls -la orders.txt');
-rw-rw-rw- 1 ethan ethan 43 Aug 25 23:50 orders.txt
Maybe you don't have write permissions on the folder?
If I perform the touch and chmod from the command line, everything works.

If I now try a ls from the command line, the return is
cannot access /var/www/orders.txt: No such file or directory
The ls -la works because the file was created from the command line.

Re: [PHP] How to send post-variables in a Location header

Hi all.
I have a scenario, wherein I need to do something like this ::
###
$original_url = /autologin.php;
$username = ajay;
$password = garg;
header('Location: ' . $original_url);
###
As can be seen, I wish to redirect to the URL autologin.php.
Additionally, I wish to pass two POST key-value pairs :: user=ajay and
password=garg (I understand that passing GET key-value pairs is trivial).
Is it even possible?
If yes, I will be grateful if someone could let me know how to redirect to
a URL, passing the POST key-value pairs as necessary.
Looking forward to a reply :)
Since this seems that it will not work, I'm wondering if you could take a step
back for us and say what is it you're hoping to accomplish by this. Maybe
there's a better way to get you what you need that is possible, and also will
be good PHP. Describe your scenario in higher level terms, not how you'd
implement it, but what the outcome you need is, and what the design goal is for
the user.

Ethan - YOU'RE DOING IT AGAIN!!!
Either you are not using error checking AGAIN!!
OR
You are showing us re-typed in code that YOU DIDNT ACTUALLY RUN.
I've told you multiple times that you need to do these two things and
you are back at it again.
The sample php above has plain simple syntax errors that would keep it
from running, which error checking would tell you IF YOU RAN IT.
Jim -
Thank you.
I don't totally understand your reply ...
but I will try to answer
The code is taken from an operating program. My error checking is set
to maximum sensitivity.
If you would point out my syntax errors, I will fix them.
TIA

You should be checking the values of $ret for each execution of system to

returning 13 - permission denied.

Re: [PHP] exec and system do not work
Ethan,
A return code of not 0 means an error occured.
Probably /var/www is not writable. Test that one by doing this:
$a = is_writable(/var/www);
var_dump($a);
If that says anything else than (boolean) TRUE, you can't write in the
directory.
Sincerely,
Jasper Kips

Re: [PHP] Alternate list for eclipse ide support?

I'm only using Java in order to make tweaks to PHPEclipse and and other support packages. ( and the same with python ). We could do with more support in these areas, and comments like yours don't help, but there IS enough interest from users dissatisfied with the alternatives ... The problem is that there are perhaps too many options and combining the activities of a few would create a more popular common base? The vast number of different 'frameworks' add further to the dilution of effort. It's a pity that there is not a single universally accepted development base in addition to a single IDE into which support could be pooled.

It seems to me there could be an easier operator than - which sometimes will make me stop and look at what keys I'm trying to hit. Just a thought. I forgot about the concatenation operator which is + in Java/C# The PHP language developers were pretty stuck. Because of automatic string-to-numeric-conversion, they couldn't use + for string concatenation. Sadly, they chose . rather than .. which I believe one or two other languages use. If they had, . would have been available once objects rolled around in PHP 4/5. I suspect they chose - since that's used in C and C++ to dereference a pointer. Actually I think .. is quite error-prone, because it is hard to distinguish from . or _ on the _first_ glance, which makes the get quickly through the code.

I'll have to try it. Those are very good products which have had a strong following for a decade. The free IDE NetBeans also has quite good support for both Java and PHP, and the latest beta version provides a web project that provides front- and back-end debugging of PHP + JavaScript. You can be stepping through JS code and hit an AJAX call and then seamlessly step through the PHP code that handles it. I use NetBeans for PHP/HTML/JS (though I am evaluating JetBrains' PHPStorm now) and Eclipse for Java. You can't beat Eclipse's refactoring support in a free tool, though I think NetBeans is close to catching up. I would bet IntelliJ IDEA for Java by JetBrains is on par at least. Eclipse' code-completion and debugger never worked for me well (and most of the time: at all). It became slower and less responsive with every release.

Re: [PHP] Off the wall - sub-domain question
So its indexing http://www.domain.com/subdomain/page.php and you would rather it index http://subdomain.domain.com/page.php. If that is the case then what Willie said holds true User-agent: * Disallow: /subdomain Place a robots.txt in the domain.com public root directory. To Googles indexer http://subdomain.domain.com/page.php and http://www.domain.com/subdomain/page.php are totally different and therefore blocking /subdomain will not affect subdomain.domain.com. Sign up for Google Webmaster and add two sites subdomain.domain and www.domain that way you can delete improperly indexed pages. Do some test scans and see if there are links on your www.domain that are linked to www.domain.com/subdomain rather then subdomain.domain.com On Thu, Aug 22, 2013 at 9:43 AM, Willie matthews.wil...@gmail.com wrote: The only way that I know of to take care of that is to put a file in your main directory called robots.txt.

That time it was (probably ;)) the best choice and nowadays I don't think it is too bad at all, beside that _other_ languages use it for other purposes now ;) C introduced . as the field access operator for structs in the early seventies, C++ kept it for object access, and Java adopted it in the early nineties. C's use of pointers required a way to access members through a pointer, and I suppose KR thought - looked like following a pointer (I agree). Since PHP was modeled on Perl and wouldn't implement objects or structs for another decade, it adopted . for string concatenation. It works fine, and I don't have too much trouble bouncing back-and-forth. I honestly would have preferred . to be overloaded when the left hand side was an object. In the rare cases that you want to convert an object to a string to be concatenated with the RHS, you can always cast it to string, use strval(), or call __toString() manually. But I'm not staging any protests over the use of -. :) Eclipse' code-completion and debugger never worked for me well (and most of the time: at all). It became slower and less responsive with every release. That was the reason I decided to leave it and I don't regret it :) I agree about the slowness, and until this latest release I've always left autocompletion manual (ctrl + space). They did something with Kepler to speed it up drastically, so much so I have it turned on with every keypress. However, it's a little too aggressive in providing choices. Typing null which is a Java keyword as in PHP, it will insert nullValue() which is a method from Hamcrest. :( After a couple weeks of this, I think I'll be switching it back to manual activation. I can type quickly enough that I only need it when I'm not sure of a method name. NetBeans, while not as good with refactoring and plugin support, is still zippier than Eclipse. And my short time with the JetBrains products found them to be fast as well. Eclipse's PHP support via PDT is not nearly as good as NetBeans, and no doubt PHPStorm beats them both. Peace, David

Re: [PHP] Re: PHP vs JAVA
Sorry in advance for the top post. Use the right tool for the Job. I've use Java, C# and PHP. 1. I hate the Perl-like object calls in PHP. I'd rather use . notation in C# and Java. It saves a lot of wear and tear on my left pinky finger. 2. Java and C# are both typed languages. Say what you want, but I have working with a string like 02 and have PHP convert that to an integer. sometimes I want that zero in front. If I want that to be an integer in Java it's int myInteger = Integer.parseInt(02); 3. Java development environments (Eclipses, NetBeans, IBM RAD) are pretty horrible. Visual Studio is hands down a better envrionment, even the older versions of it. I've hooked Visual Studio into SVN in the past and it works well. 4 PHP development environments are many and varied and all of them suck at web debugging. I've used PHPEdit, Zend, Bluefish, Eclipse and a couple others. Bluefish works better on Linux than it does on Windows. Use the tool for the job at hand.

2013/8/21 Curtis Maurand cur...@maurand.com Sorry in advance for the top post. Use the right tool for the Job. I've use Java, C# and PHP. 1. I hate the Perl-like object calls in PHP. I'd rather use . notation in C# and Java. It saves a lot of wear and tear on my left pinky finger. Actually the problem is, that the dot . is already in use. With $foo.bar() you cannot tell, if you want to call the method bar() on the object $foo, or if you want to concatenate the value of $foo to the result of the function bar(). There is no other way around this than a different operator for method calls. 2. Java and C# are both typed languages. Say what you want, but I have working with a string like 02 and have PHP convert that to an integer. sometimes I want that zero in front. If I want that to be an integer in Java it's int myInteger = Integer.parseInt(02); 3. Java development environments (Eclipses, NetBeans, IBM RAD) are pretty horrible. Visual Studio is hands down a better envrionment, even the older versions of it. I've hooked Visual Studio into SVN in the past and it works well. Ever tried the jetbrains products? :D (No, they don't pay me) 4 PHP development environments are many and varied and all of them suck at web debugging. I've used PHPEdit, Zend, Bluefish, Eclipse and a couple others. Bluefish works better on Linux than it does on Windows. I use PhpStorm and it works quite fine. Use the tool for the job at hand.

Because of automatic string-to-numeric-conversion, they couldn't use + for string concatenation. Sadly, they chose . rather than .. which I believe one or two other languages use. If they had, . would have been available once objects rolled around in PHP 4/5. I suspect they chose - since that's used in C and C++ to dereference a pointer.

The free IDE NetBeans also has quite good support for both Java and PHP, and the latest beta version provides a web project that provides front- and back-end debugging of PHP + JavaScript. You can be stepping through JS code and hit an AJAX call and then seamlessly step through the PHP code that handles it. I use NetBeans for PHP/HTML/JS (though I am evaluating JetBrains' PHPStorm now) and Eclipse for Java. You can't beat Eclipse's refactoring support in a free tool, though I think NetBeans is close to catching up. I would bet IntelliJ IDEA for Java by JetBrains is on par at least. Peace, David

Re: [PHP] PHP vs JAVA
I think the big takeaway there is that JAVA is one of the primary language for larger companies and applications. Start ups tend to use smaller easier to use tools like php / javascript / python / ruby.

Python programs fail in the most ungraceful way I've ever seen in an interpreted programming language. (Don't even start in on C. It's a compiled language.) Java is an incredibly heavy language for web work. Much like Ruby but more so.
