Also, when in doubt, I find it's usually a good idea to check the output
being sent with a more low-level tool, such as Fiddler, so that you can view
the raw values rather than leaving it up to your browser to interpret them.

I recently used rsync (for the first time, even) in order to transfer an
entire directory structure of several thousand files and folders from one
VPS host to another. It worked like a dream, and the standard output could
be captured to build a report such as the OP was asking for.
Srsly, man -- take Ashley's suggestion and at least check it out. :)

Hello,
my idea is to make a backup of some paths of my laptop via PHP.
I like to use a MySQL Datebase to trace which file was uploaded

Also it should be uses to look up it is nessasery to backup this
file
because it was changed since last time or not.
All this files should be uploaded to the SERVER in a special
folder
where
this files run to a tape backup machine.
I hope some one can give me some ideas for this.
Kind Regards
Jens Geier
There's a few ways to go about doing this, but I reckon you
should
do
something similar to the following:
* schedule a cron job to run as often as you want the backup
to
be
done, and have the cron call a script
* the script can either be php and use your own code to
create
copies of files and check file dates for backup purposes,
or
use
the rsync tool which pretty much does all of this for you
automatically
* update a database as you need. this can be done either
from a
php script or directly via mysql on the console
If you do use PHP for this, you'll want to code it as a CLI
script
rather than a web page script. On the whole it won't make much of
a
difference, but obviously some global variables will change a
bit.

Hello Ashley,
i try to make a backup from some paths of my local laptop harddrive to
a
folder on my server. Even if i'm not in the company.
If i'm outside (this time i'm in China) i have to copy it through the
Internet that is using http or ftp transport protocol.
The start of the copy is when the user clicks to a buttom and start
the
backup process.
Kind Regards
Jens Geier
The script needs to be set up on your local machine. I don't think HTTP
will help you much here, as that isn't great for transferring files
upstream I've found. Googling 'rsync ftp example' brings about over
230,000 results, have you actually tried looking?
Thanks,
Ash
http://www.ashleysheridan.co.uk
No, i have not.
Because i also think that there will not a finish software.
So i think i have to write something by my own.
That is the reason i ask for ideas to do so.
I just read here the following thread:
[PHP] Read directory; store filenames found in mySQL table?
That is something that is running in that direction in try to go.
Kind Regards
Jens Geier
But I've told you that the best tool to do it is rsync. This is a tool,
not a whole large peice of software with a GUI, etc. You use it in
conjunction with other software to achieve what you need. Have you even
looked up at what rsync is?
Thanks,

I've been using rsnapshot (it uses rsync) to do backups of remote server
directories:

Just thought I'd throw it out there :)

Hi,
I'll be honest: php is not my favorite programming language. That honor
goes to ruby. And I don't mean ruby-on-rails; just straight, pure
unfettered ruby. I use ruby to write web applications and just about
everything else.
However, there are obviously very many web applications and webapp
frameworks written in php. I have recently taken an interest in eyeOS
(http://eyeos.org/), with the intent to hack eyeOS to use a certain ruby
back-end file service I've written instead of accessing the local file
system directly. This ruby service communicates with clients via ruby's
native "distributed ruby" (DRb) facility. DRb makes it marvelously easy
to write distributed multi-threaded services, provided the clients are
written in ruby as well.
But what if the client is written in, say, php? Wouldn't it be nice if a
php client could access DRb-driven ruby services just as simply as a
ruby client can? Not finding any such existing facility, I've written a
php object class, "DRbClient". This class invokes object methods offered
by the remote ruby service, passing strings, integers, floats, booleans,
nulls, and/or arrays as arguments, and accepts a return value of any of
those same types. All data translation and inter-process communication
is transparent. It's just as if a local object instance is being
messaged directly.
If there's interest, I'd like to offer DRbClient to the php community,
but I'm not sure how to go about that.

If that is based in a class written in PHP, you may want to submit it to
PHPClasses.org . It has hundreds of thousands of registered users eager
to learn about new PHP classes.
http://www.phpclasses.org/
As for distributing processing over multiple threads running eventually
on different machines, that sounds more like a job for Gearman.

I am working on designing an documenting a process for our team to use to
manage code updates/changes.
What we've been doing has been ghastly: a bunch of developers using
dreamweaver's 'check in/out' functions, all using the same FTP login, to FTP
files to the production server.
It turns out the site we're working on together is a bit too complex for
this, so it's on me to come up with a better way.
I'm a big fan of SVN and think we'll be light years ahead of where we are
presently by using SVN to manage code revisions.
So, I've set up an SVN repository on our dedicated server and imported all
of the live-site code. Then I set up a dev virtual host (dev.domain.com) and
exported all of the code in my repository to that vhost's DocRoot. So...that
gave me a copy. Next, I copied the MySQL db to a separate db that we'll use
for the dev server...so dev code doesn't query the live db. Then of course,
I had to edit the config files that have DSN information in them to make
sure my dev site actually uses my dev db.
Here's where the problems start to creep in...
If I export the whole repository from SVN to the dev DocRoot directory, I'm
going to overwrite the config files that have DSN info in them. Similarly,
there are some javascript files that declare variables like var base_url = '
http://mysite.com'...those variables need to be set once for the environment
(my local IDE? the dev server? the production server?) and then not messed
with afterward.
After an SVN commit, it's really easy to svn export svn://localhost/mysite
/path/to/my/dev_server
Simple, all of the code in the repository goes to the dev server.
The issue I'm having is that there are a number of files that I do NOT want
to be copied from the repository to the dev server, except on
rare occasions.
So, I can choose to add the files to my svn:ignore in my working copy so
they aren't committed/updated. But I can't ensure that all of the developers
take this step and it's not a reliable way to keep those select files in the
repository out of my dev server.
Or, I can write a shell script that does the SVN export, then overwrites the
selected config files with master versions that are stored somewhere else
and not edited by any of the team. One problem with that though, is that our
main javascript file tends to be edited/changed and it's one that can create
problems if that base_url var isn't appropriate to the server it's on.
Or, in all of my PHP files, I can write the config values into switch
statements:
switch($_SERVER['HTTP_HOST']) {
case 'mysite.local':
// local IDE config directives
case 'dev.mysite.com':
// dev server config directives
// etc...
}
...but that leaves the production server DSN sitting around in development
code, which I'd like to avoid, and I don't have an analogous solution for my
javascript files.
JS question: is there a js way to do the same thing? Evaluate the js
equivalent of PHP's $_SERVER['HTTP_HOST']? If there is, I think this
solution will work.
This has got to be a fairly typical workflow and problem.
What are some of the strategies you folks use for designing your flow of
code from local IDE to SVN to dev server to production server?

I do not see the reason why you would need an absolute URL like var base_url
= '
http://mysite.com' in your javascript code.
If only this is giving you problems, use: *window.location.hostname* to get
the hostname in javascript.

personally I just use a switch and a couple of sh scripts to roll out;
for the development environment I run the update-dev.sh script as an svn
commit hook so dev is updated on every commit; for uat/live it's
requires a manual run of ./update-live.sh (in reality i actually use
phpUnderControl for continuous build automation and it only rolls out to
live when a build/revision passes all unit tests).
To deal with custom files per site; I keep all user submitted
site-specific content in separate storage directories outside of the web
root which solves half the problem; and for the remaining
config/htaccess/cache files its just a case of using a few lines of bash
script to ensure domain specific stuff isn't wiped out on roll-out.
on the HTTP_HOST side of things I personally try to negate the use of
domains in urls wherever possible opting for /path/to/file.js instead -
but when it does creep up you can easily negotiate then by doing a
simple string replace:
define( 'DOMAIN' , 'clientsite.com' );
function u( $uri )
{
return str_replace(DOMAIN, 'http://'.$_SERVER['HTTP_HOST'].'/', $uri);
}
echo u( 'http://clientsite.com/some-page/' );
and on the js side you could use document.domain or
window.location.hostname or suchlike
ps non of this is worth arguing over, just something to get you going

Hello,
In a mysql date() field, I set the default to "0000-00-00".
Therefore, $mydata->birthday = "0000-00-00";
But when I run this next line, $then = 1969.
$then=date("Y", strtotime($mydata->birthday));
Why 1969, and not 0 or nothing?
If I echo strtotime("0000-00-00");
Nothing appears. So $then should be nothing?
What is wrong with my logic?
Thanks,
John

MySQL uses a default "0000-00-00" value for date fields generally, but
when converted into a timestamp, the string equates to a false value. In
PHP, timestamps are numerical values indicating the seconds since
Midnight of the 1st January 1969. As PHP uses loose data typing, false
is converted to a 0 (zero),and strtotime("0000-00-00") returns false. As
such, it is treated as the date when time began (for the PHP date object
at least).
There's nothing wrong with your logic, but if you want to check for
empty values, then you should use an extra if statement to check if
strtotime("0000-00-00") === false

When you set the date to "0000-00-00", you start the following sequence:
1. strtotime returns false, because "0000-00-00" isn't a date it can
parse into a timestamp.
2. date returns 1969, because it's not passed a valid timestamp and it
works from December 31, 1969 for any invalid date.

Why is this? Unixtime starts at January 1st 1970 GMT (see for instance
http://php.net/microtime), I've never heard of the other dates you
mentioned.
My guess is the time, date or GMT is wrong for Johns setup and that's
why he get 1969 and not 1970, cause something is seting time in the past

I've not read this, but if the first valid date is Jan. 1st, 1970, then
passing that date back in the case of errors would lead to ambiguity. Is it
a valid date or is it an error. Passing back the date of the day just
before (in terms of time, I think it's the second before) the first valid
date lets you easily identify an error.
Again, I didn't read this anywhere, though, and I could be wrong.

Time zones. If I have PHP spit out a date for "0" as a string on my system,
it comes back as 18:00 on December 31st, 1969, because I am in the Central
time zone.

Hey
Haven't had the time to read up on the maillist, but here's my input.
Mattias Thorslund wrote on 09/01/2010 02:26:
To my eyes, ?> means "look there is more content coming", which seems
kind of silly when there isn't.
To mine it means, no more PHP code for now. I don't wanna make it
diffenrent from a file containing pure PHP code or one that contains
both PHP and HTML, where I jump in and out of the PHP tag.
Remember the ?> stops the parser
And I find it bad coding standard to start a tag and not end it, even if
it's possible. Remember Perl is a smart, but also terrible language,
where one can leave out the ; in the end of a oneline script and make a
bunch of stuff on $_ without showing what variable you're working on.
And finally, mysql_close() was always called after a script was closed,
so I've never learned to practice that and for the last ten years I've
seen only _one_ developer added that function call to the end of his
files. In PHP6 that call is required, so making the cleanest code is in
my opinion more readable and also more correct, since you'll never know
what the PHP core team will come up with next ;-)
A neat thing with pairing every <?php with a ?> when mixed in HTML is
that these are valid XML processing instructions. If your HTML satisfies
XML well-formedness, your PHP document will also be valid XML. Not that
I've ever had any need to process my layout templates as XML but anyway.
I don't see your argument. PHP generates HTML or XML files. When you're
aware of the XML tag of course you make sure the XML file generated is
valid. Why would you ever add PHP code to a HTML file (other than for
documentation, examples etc.)?

I leave ?> out.
I'm pretty careful about my code formatting and whitespace.
It's my opinion that if I can eliminate a potential problem by not including
an optional closing tag...there's really no reason why I shouldn't.
What is the difference between:
<?
print "hello PHPeople";
?>WHITESPACE
and
<?
print "hello PHPeople";
WHITESPACE
Same shit when I look at it, a sloppy developer is what it is :-)

Plenty of differences, if you include the first one as a file, the
whitespace gets sent to the browser because it is not part of the PHP,
and so is assumed to be HTML. Once this happens, the headers have been
sent, so you can't use different headers in your script.

What has been said on this thread a few times is it is not always a
developer error, but a bug with the editor, which is not something that
will be picked up until it occurs.
