[PHP] Working with internal data formats
What technique can I use to take an 8-byte double precision value, as stored internally, and assign its value to a PHP float variable without having the bytes misinterpreted as a character string. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Does it get misinterpreted, or do you just want to be sure? The documentation says - Some references to the type double may remain in the manual. Consider double the same as float; the two names exist only for historic reasons. Does this cover your case? Iv No. Example: I extract the 8 bytes 40 58 FF 5C 28 F5 C2 8F from an external file, which is the internal double precision float representation of the decimal value 99.99. Starting with that byte string, how can I create a PHP variable whose value is 99.99? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: menu andfolder question
Unless I misunderstand your question, this is normal behavior. The page designer purposely enters the link in the simpler form: http://www.zend.com/en/company because the web server is configured to assume that index.htm is the default page in that folder and correctly displays it.

[PHP] HTML form upload works, CURL fails when uploading file from c:
PHP 5.2.1 on Apache/Linux. Client is Firefox and IE7 on Windows XP.
Uploading C:\boot.ini works great from an HTML type=file form element
but fails using what should be the equivalent:
curl_setopt($ch,CURLOPT_POSTFIELDS,array('peru'='@C:/boot.ini'));
CURL error is failed creating formpost data. Same CURL works when the
test file resides on the PHP server:
curl_setopt($ch,CURLOPT_POSTFIELDS,array('peru'='@/home/user/boot.ini'));
so problem seems to be in the '@C:/boot.ini' filespec. Substituting
'@C:\boot.ini' or '@C:\\boot.ini' doesn't help.

Well, dope slap I think I understand the problem now: CURL is
operating from the server so it knows nothing about C: on the client!
So how do I solve my problem? I want to upload multiple files from C: to
the server based on a single wildcard spec typed into an HTML form by
the user.

[PHP] can't figure out proper format for c:\ path for curl upload
I can't figure out how to pass a c:\... filepath via curl for an RFC1867
multipart form upload in PHP 5.2.1.
I'm using the following code to perform a programmatic file upload to
the PHP server:
$filepath='/home/user/testfile.txt';
$ch=curl_init('http://bucksvsbytes.com/upload.php');
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,array('peru'='@'.$filepath));
curl_exec($ch);
curl_close($ch);
Works great if the file I want to upload is on the web server but it
never is. The files I want are on the client computer, of course, e.g.
c:\home\user\testfile.txt
I've tried passing every variation of that path I can think of, e.g.:
C:\home\user\testfile.txt
C:\\home\\user\\testfile.txt
C:/home/user/testfile.txt
urlencode(...)
utf8_encode(...)
and nothing works. I either get the dreaded failed creating formpost
data or the filepath shows up in $_POST and $_FILES is empty. The
listed formats don't work with fopen() either.
I've searched dozens of web examples but I can't get it. Help!
For that matter, is there a better approach than curl for programmed
uploads of client computer files to the PHP server?

[PHP] Retrieving response headers from an off-site page
I'm trying to programatically retrieve a sales tax lookup page using file_get_contents() but the page doesn't return data unless a session id is first retrieved and then supplied. You can see how it works as follows: The first time I send the following request: http://www7.nystax.gov/STLR/stlrHome?street=48%20central%20avezip=12472B1=Lookup%20Address I get an empty form back, and one of the response headers is Set-Cookie with a value of, say, JSESSIONID=0001WQEmZF6tI-yClq4S9_7a8ii:10amela49;Path=/ If I then reload the same URL, the resulting page includes the desired info, probably because the second time one of the request headers is Cookie with a value of JSESSIONID=0001WQEmZF6tI-yClq4S9_7a8ii:10amela49 I want to get the second version of the page, the one with data, using file_get_contents(), but it appears I first have to get the page to return a sessionid and then I have to send it in a Cookie header the second time. Reading the first GET's response headers and sending the needed request header on the second GET - in combination with file_get_contents() - is just beyond me. Can anyone enlighten me?

Re: [PHP] Startinga shell process with a life of its own
Great approach! Slicker'n snot. I added one enhancement: The shell script writss progress info to the database which the trigger page displays on entry. Richard Lynch wrote: I would recommend, however, that you re-structure things slightly so that the Architecture is more like this: User visits web page. Page generates a database record of what needs to be done. Page finished. CRON JOB: Look in task list of what needs doing, and do some of them. Make sure only one job is done at a time, or whatever race conditions are handled here.

[PHP] Startinga shell process with a life of its own
Which PHP method allows me to start a shell process from a web page script and let it proceed to its conclusion even though I end the page. Most of the various execute functions seem to wait for the process to finish before PHP continues. I don't understand the ones with open/close functions. Will opening a process and failing to close it let it run after the page ends? Will failing to close cause other problems? Can you point me to example code? The shell commands I want to run are typically themselves PHP programs whose execution time is far too long to complete in a browser context.

[PHP] serve long duration pages
This may be more appropriate for an Apache or browser forum. Perhaps you can suggest an appropriate one. I have a PHP script that takes a long time to complete (due to very heavy database activity) although it echoes unbuffered output every few seconds. I've set max_execution_time to 0 with set_time_limit(0) so PHP doesn't time out the page but after about 3 minutes, Firefox says, The connection to the server was reset while the page was loading. and IE7 says, Internet Explorer cannot display the web page. I want to try apache_reset_timeout() but it's not implemented in 4.3.10. Is there anything I can do from PHP or elsewhere to solve this?

Re: [PHP] serve long duration pages
You're right sads (self-administered dope slap), my task is really not a web function except for the need to trigger it from an admin page. I'm going to use the PHP command line interface to run it without web interaction. However, there are still situations where a web script may sometimes involve long run times depending on the parameters supplied by the user (an example might be a SQL execution page where the user-supplied query could range from simple to very complex). I'd still like to know how to communicate via PHP that I want an infinite timeout for a particular web page.. lets start by saying that any webpage script that takes that long to run is shit by design.

[PHP] SVG page displays correctly, but not when generated by PHP
Does anyone have any idea why I can display a true SVG file successfully in IE 6 with Adobe SVG viewer 3.0, but not when the identical content is generated by PHP. Example: SVGRECT.SVG displays properly (Apache server includes directive AddType image/svg+xml svg): ?xml version=1.0 encoding=UTF-8 standalone=no ? !DOCTYPE svg PUBLIC -//W3C//DTD SVG 1.0//EN http://www.w3.org/TR/SVG/DTD/svg10.dtd; svg rect x=10 y=0 width=460 height=50 / /svg However, SVGRECT.PHP, which results in the same page text, brings up a dialog box Would you like to open the file or save it to your computer? Choosing Open causes nothing to happen. Choosing Save results in another dialog box Internet Explorer was unable to open this internet site: ?php header(Content-type: image/svg+xml); echo ?xml version=\1.0\ encoding=\UTF-8\ standalone=\no\ ?; echo \n!DOCTYPE svg PUBLIC \-//W3C//DTD SVG 1.0//EN\ \http://www.w3.org/TR/SVG/DTD/svg10.dtd\;; echo \nsvg; echo \nrect x=\10\ y=\0\ width=\460\ height=\50\ /; echo \n/svg; ? Displaying SVGRECT.PHP from another PHP page using the embed tag works properly. Here's another curious occurrence that may be related: displaying any php page as a local file brings up the Windows Open with dialog, whereas referencing the same page as a URL works.
