An afterthought, handling streams and parsing at the same may require
sophisticated XML node validations as the node maybe split between the

Re: [PHP] Input variable from form help request
Hello Richard,
Your suggestion worked perfectly.
Basically, I just copied and pasted your example
and with a few, very minor adjustments, it works beautifully.
Many thanks for your help.
All the best.

$errors= error_get_last();

You need to keep track of the opening and closing quotes (single and double).
In the copy() function, I'm using the embedded variable method (a
string using double quotes will evaluate the variables at run time).
In the echo statements, I'm not using concatenation as, theoretically,
it should be faster as the echo statement will not need to first build
the concatenated string before echoing it. It will just push the
values out the to the web server. I think. I've not done any metric
testing on that.
As for copying a file TO a http URL, you need to obey the rules of
http. CURL or FTP will be the protocols of choice here, though you do
have the option of using a stream context to wrap the
file_put_contents() into a POST form to the site (similar to CURL in
some ways).

Richard,
Only think I can think of is break up into 2 parts. 1st part use cURL for
the down streams and monitor it's progress. 2nd part is XML parsing. If
you want to do both simultaneously and only if the remote supports chunked
encoding/transfer, you could use multiple handles of cURL into numerical
indexed array variable containing the chunks for XML parsing. This could be
memory intensive if the file is very large, depending whether you free the
elements in the array as you progress. So if memory consumption is a major
concern, you may want to save to the file locally until the import/migration
is done as there maybe a situation where you'll need to review the data and,
thus, saving the time and bandwidth of having to re-download the data.

Printing as you read/progress means carrying less than entire book. Any decent book will range in about 400+ pages. Another good side to printing as you go is that a thick book wouldn't seem overwhelming for beginners as to how much information they have to digest and absorb, especially someone who is new to IT and not used to reading thick books/manuals. As for the book giving real world experiences, that's only to give you small idea of what you _may_ encounter. Personally, I find that too broad and in depth to encompass in a book unless it's a(n) auto/biography. A good example to that is accessing database. How do you explain to someone new which he/she should use and why: straight access via client library, ODBC, PDO, abstraction/wrappers, ORM, and/or any combination there of. Although this requires some understanding of PHP, I don't recall any book hinting or briefly explaining all the possible methods of DB access. A long time ago, I wrote an abstraction wrapper that would allow me to access any DB that PHP supports and allow simultaneous connections to same and/or different DBs because my need was there. That same wrapper would allow DB specific operations too. IIRC, this was long before

[PHP] Getting meta data (of any type) for an XML file being from it's URL.
Hi.
I'm looking to process very large XML files without the need of first
downloading them.
To that end,
SimpleXMLIterator('compress.zlib://http://www.site.com/products.xml.gz')
is working perfectly.
But a downside is that I have no information of my progress.
Is there any mechanism available to get a position within the XML stream?
I can use libxml_set_streams_context() to set a context (so I can
provide POST data if needed for the HTTP request), but I can't see how
to gain access to the stream within the libxml code (SimpleXML uses
libxml).
At the most basic, what I'm looking for is to be able to record a
percentage complete. Even with compression, I'll be reading some bytes
from a stream (either from http or from compress.zlib) and I want to
know where I am in that stream.
The HTTP header will tell me how big the file is (so that can easily
be a HEAD request to get that data).
Even if I DO save the file locally first, I still can't get a position.
If I use the SimpleXMLIterator::count() method, I am unsure as to what
will happen if I am using a stream (rather than a local file). If I
use ...
$xml = new SimpleXMLIterator(...);
$items = $xml->count();
foreach($xml as $s_Tag => $o_Item) {
...
}
will the XML file be cached somewhere? Or will that depend upon the
originating server supporting some sort of rewind/chunk mechanism?
Any suggestions/ideas?
Richard.

I recall that cgi/fastcgi requires different configuration than from isapi type - dll/dso. I don't know how httpd handles impersonation on *nix platform as I've never had to configure it that way. Here's a few from the php.ini ; The root of the PHP pages, used only if nonempty. ; if PHP was not compiled with FORCE_REDIRECT, you SHOULD set doc_root ; if you are running php as a CGI under any web server (other than IIS) ; see documentation for security issues. The alternate is to use the ; cgi.force_redirect configuration below ; http://php.net/doc-root ; cgi.force_redirect is necessary to provide security running PHP as a CGI under ; most web servers. Left undefined, PHP turns this on by default. You can ; turn it off here AT YOUR OWN RISK ; **You CAN safely turn this off for IIS, in fact, you MUST.** ; http://php.net/cgi.force-redirect ; if cgi.nph is enabled it will force cgi to always sent Status: 200 with ; every request. PHP's default behavior is to disable this feature. ; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI. PHP's ; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok ; what PATH_INFO is. For more information on PATH_INFO, see the cgi specs. Setting ; this to 1 will cause PHP CGI to fix its paths to conform to the spec. A setting ; of zero causes PHP to behave as before. Default is 1. You should fix your scripts ; to use SCRIPT_FILENAME rather than PATH_TRANSLATED. ; http://php.net/cgi.fix-pathinfo ; FastCGI under IIS (on WINNT based OS) supports the ability to impersonate ; security tokens of the calling client. This allows IIS to define the ; security context that the request runs under. mod_fastcgi under Apache ; does not currently support this feature (03/17/2002) ; Set to 1 if running under IIS. Default is zero. ; http://php.net/fastcgi.impersonate Note that the above is from old config file and is configured for PHP to run as FastCGI on IIS7.5. There maybe recent changes regarding httpd and impersonation. Go through the php.ini and make all relevant changes regarding 'cgi'. Regards, Tommy

This line:
if(!@copy('http://mydomain.com/files/".$_POST['trakname']."','/".$_POST['dirname']."/".$_POST['trakname']."'))
looks like a big mess of single and double quotes to me. Why don't you go
through it very carefully? I'd be inclined to make a small test program
separate from the web page stuff and do things like:
http://mydomain.com/files/".$_POST['trakname']."','/".$_POST['dirname']."/".$_POST['trakname']."';
echo $myvar;
?>
and fiddle until that works.

[PHP] PHP5 cgi Suexec htaccess rewrite issue
I am running a server with cPanel on and want to have php run as a cgi with Suexec enabled I cannot seem to rectify an issue, when I set the handler to cgi, my rewrite rules on one of my sites stop working Sample url: http://examplesite.com/ad/123-abcde/ The rewrite rule for this is below; RewriteEngine on RewriteBase / RewriteRule ^ad/([0-9]+)(.*)$ ./index.php/ads/ads/action/viewAd/frmAdsID/$1/adTitle/$2 [L] Currently the php 5 handler is dso, and the rewrite rule works perfectly. If the handler is set to cgi, the rewrite rule does not work and I the site just displays the home page. I am at a loss and would appreciate some help. Thanks in advance!
[PHP] Input variable from form help request
I'm trying to create a standard web form that will use a PHP script
to copy a file from one server to another.
Both servers have the files in publicly accessible directories.
The html form I'm using follows...
Enter the filename you wish to copy.
Enter the directory at mydomain.net where this file should be placed.
The PHP script I'm calling with that form follows...
http://mydomain.com/files/".$_POST['trakname']."','/".$_POST['dirname']."/".$_POST['trakname']."'))
{
$errors= error_get_last();
echo "COPY ERROR: ".$errors['type'];
echo "\n".$errors['message'];
} else {
echo "File copied from remote!";
}
?>
I'm receiving an "unknown T string" error on that line, but don't
know where or what that may be.
The same PHP script does work quite well for the purpose when used
with static data, so the problem seems to be an incorrect method of
inputting a form variable.
The PHP script that works follows...
http://someserver.com/somefile.zip
','./somefile.zip'))
{
$errors= error_get_last();
echo "COPY ERROR: ".$errors['type'];
echo "\n".$errors['message'];
} else {
echo "File copied from remote!";
}
?>
I hope someone may be willing to help me correct my form input
problem, or suggest a better method of copying a file, input from an
html form, from one server to a directory, also specified through the
form, on the local server where the script is being called from.
Many thanks in advance for any suggestions. I've been messing with
this for days without discovering where my error comes from.
