I need to use SFTP to send text files and binary files from one server
to another, but I'm unable to use fopen on the remote server, and if I
send with ssh2_scp_send the files are truncated. I'm assuming the
libssh2-PECL/ssh2 installation isn't the problem because I'm able to
connect using ssh2_auth_password, create a directory on the remote
server with ssh2_sftp_mkdir, and copy files with ssh2_sftp_send and
ssh2_sftp_recv (even though ssh2_sftp_send truncates files).
When I try to use fopen, I get this error message:
Warning: fopen(): Unable to open ssh2.sftp://Resource id
#10/whatever.com:22/home/whatever/public_html/flamingo/test.txt on
remote host in /home/user/public_html/cms/sftp_test.php on line 79
Warning: fopen(ssh2.sftp://Resource id
#10/whatever.com:22/home/whatever/public_html/flamingo/test.txt):
failed to open stream: Resource temporarily unavailable in
/home/user/public_html/cms/sftp_test.php on line 79
Here's line 79 of sftp_test.php:
$stream =
fopen("ssh2.sftp://$sftp/whatever.com:22/home/whatever/public_html/
flamingo/".$filename, "wt")
I've read "Secure Communications with PHP and SSH" in the February PHP
Architect. That's what prompted me to try PECL/ssh2, but now I'm stuck.
Anybody successfully using fopen with SFTP or anybody using
ssh2_sftp_send without getting truncated files?

yes. is it easy? that depends on how far you want to go with diff'ing
(and how good you are at string manipulation :-)
this is a general problem which has been solved by very skilled people
already, I would suggest reading some more about 'diff' etc and
figure out if you can use existing tools to get what you want:

I believe you will find it more feasible to throw your two messages into
files and use exec() to call diff on them than to write essentially all of
"diff" in PHP...

Untested, very crude:
<?php
$maxlen = max(strlen($text1), strlen($text2));
for ($i = 0; $i < $maxlen; $i++){
if (@$text1[$i] == @$text2[$i]) echo @$text1[$i];
else @echo "<font color=red>$text1[$i]|$text2[$i]</font>";
}

Would it be possible to explode both messages on " " into an array and
run array_diff() and work from there?

donot you think you program will just bring the server to its foot ,if the
text message encountered is very large of order of 40 KB or
larger.is<http://larger.is>there any other efficient method.

Hi there,
I am trying to find out how to match a search on : 5a or 5b with array search.
Basicly I would like to make it true as soon as the function finds a value
starting with 5.
As for now I have:
if (array_search('5a', $emsg) OR array_search('5b', $emsg)){
...
that statement will get very long till z :-)
Any ideas how to make something like this:
array_search('5*', $emsg)
Thank you for any hint,
Merlin

How about something like:
search($emsg)
{
for($i = 0; $i < count($emsg); $i++)
if(preg_match('/5[a-z]/', $emsg[$i]))
return $i;
return -1;
}

I believe that in recent versions of PHP, the preg_* functions will accept
an array as an argument... Or maybe I dreamed that.
You should benchmark the solutions and also consider just using implode()
on the array to make a giant string and search that.
Depending on a lot of factors, any of these could out-perform the others.
Try it with data as close to real-world as you can get.

Hello, I've been trying to figure out on how I could evaluated this
array and combine like items... here is the array.. it represents a
shopping cart contents.. you'll notice that the first array is the
same as the third... what I am trying to do is combine the quantity of
the first array and the third... I am not asking from someone to
program this for me... just for someone to give me a heads up on if
there is a array function I could use. Thanks for any help!
------------- array example --------------------
$ARY_cart[] = array( 'product_id' => '123',
'sku' =>
'DFBag-12',
'quantity' =>
'2',
'product_name'
=> 'Dog Food',
'unit' => '12
lbs. Bag',
'price' =>
'12.05'
);
$ARY_cart[] = array( 'product_id' => '224',
'sku' =>
'cFBag-6',
'quantity' =>
'1',
'product_name'
=> 'Cat Food',
'unit' => '8
lbs. Bag',
'price' =>
'4.25'
);

Hi,
That's what I've done, but I does not say clearly _when_ @rename
should failed. I've read the documentation in the C library for Unix,
and it says that it failed when it can't _add_ an entry to the
directory. What I observe is an empty file...
still weird, I'll look depper into it. (since i've been bitten by it
with my website being 'blank page' since it grew out of space...)
Thanks,

It will probably return 0 (or maybe -1) on error.
It may or may not also fill in $php_errmessage (?) or whatever the
variable is called.
It should be documented at http://php.net/rename what error codes it returns.
If not, you could run some tests fairly easily.
> I do a : @rename($old, $new), what happens if I run out of space ?
It won't work, and you have suppressed the error message, so you won't
even know it didn't work.
Using @ like that is just a Bad Idea.
You need to write better software that handles error conditions and does
something reasonable about them.
? is
> the rename just an alias for C function library ?
Pretty much, but not to the point that it blindly returns whatever the C
'rename' returns, probably.
You could read the PHP source and find out :-)

I think I solved the issue i was having... I would be willing for any
optimization though.. .here is what I did
------------------------- code -------------
$ARY_cart[] = array( 'product_id' => '123',
'sku' => 'DFBag-12',
'quantity' => '2',
'product_name' => 'Dog Food',
'unit' => '12 lbs. Bag',
'price' => '12.05'
);
$ARY_cart[] = array( 'product_id' => '224',
'sku' => 'cFBag-6',
'quantity' => '1',
'product_name' => 'Cat Food',
'unit' => '8 lbs. Bag',
'price' => '4.25'
);
$ARY_cart[] = array( 'product_id' => '123',
'sku' => 'DFBag-12',
'quantity' => '24',
'product_name' => 'Dog Food',
'unit' => '12 lbs. Bag',
'price' => '12.05'
);
$cart_count = 0;
$cart_total = count($ARY_cart);
foreach ($ARY_cart as $key => $ary_value)
{
do{
if($ary_value['product_id'] ==
$ARY_cart[$cart_count]['product_id']
&& $key <> $cart_count)
{
$ARY_cart[$cart_count]['quantity'] =
$ARY_cart[$cart_count]['quantity'] + $ARY_cart[$key]['quantity'];
unset($ARY_cart[$key]);
}
$cart_count++;
} while ($cart_count == $cart_total);
$cart_count = 0;
}

Sure.
Change your LINK to a FORM with an INPUT TYPE="image" and use
METHOD="POST" on the FORM tag.
<form method="post"><input type="image" name="clicked"
src="images/clicker.jpg"></form>
<?php
if (isset($clicked_x)){
echo "($clicked_x, $clicked_y)<br />";
}
?>
I dunno why everybody else gave you such complicated answers.
It's still not a PHP question, though, except it's confusing PHP changes
".x" and ".y" into "_x" and "_y" on the variable names because "." is not
valid in variable names. :-)
There, that made this post on-topic. Sort of.

http://php.net/ksort
Last time I checked, PHP would still convert an object to an array if you
forced it to...
If not, there are introspective functions to examine your object and all
its properties, and surely you could build the array yourself and then
ksort it.

The bogus User Contributed note about REMOTE_USER is, well, bogus, almost
for sure.
If that fails, I guess you could try:
<?php
ob_start();
phpinfo();
$phpinfo = ob_endclean();
?>
Then you have to dig out the PHP User from that.
It's possible there is a PHP Constant here that is the User:
http://php.net/manual/en/language.constants.predefined.php
If none of those work, I'm guessing even Windoze has something like
"whoami" so you could http://php.net/exec "whoami" or its equivalent,
based on the http://php.net/php_sapi_name
If all that fails, I'd just give up. :-)

If you've got the Hello.exe running, but not returning, you could *MAYBE*
do :
<?php exec("Hello.exe &", $output, $error);?>
The & will put it into the background, even in Windoze, I think... If
not, figure out how Windows starts background tasks, and do that.
Or make Hello.exe actually be a tiny little program that forks off the
program you really want to use, and then returns.
Or... Lots of ways to try to force the OS to fork the process.
