Re: [PHP] Images don't save
You can't. Period. Simple as that. Oh, and BTW, it's not even a PHP question...

[PHP] General
Guys, I want to randomly pick one of a number of values, with given probability for each item, e.g. abc 50% def 25% ghi 25% The obvious way is to take a list where the 50% item is given twice and then randomly pick one, but what if I want to use a probability of 51.3% (and don't tell me of a list with 1000 entries and 513 times the 'abc' item *g*). This seems to be trivial, but I just can't think of a simple and proper way to do it. Any ideas? Regards, Gunther E.

[PHP] html output done without result of exec_shell
Guys, I'm trying to output the result of a shell command within a page. Problem is, when it's a command with short execution time like echo shell_exec(ls -la); it works fine, but the command I'm really trying to execute takes 2-3 seconds before having calculated the response and by then, the page is already done and the output of the command isn't included. I played around with the settings in php.ini, but none of them changed the problem. Maybe an Apache problem? What am I missing? Thanks in advance. Regards, Gunther E.

Re: [PHP] html output done without result of exec_shell
Hmm, yes, did so, even as the user that the webserver is running as. Switched to another webserver software (caudium) on the same machine and had the script running there, works fine, takes the 2-3 seconds and the output is included as intended. Huh?

Weird, built a newer apache version, and it runs like hell. Thanks for your help. On Thu, 28 Feb 2002 22:45:52 +0800, Jason Wong wrote: On Thursday 28 February 2002 20:30, Gunther E.

RE: [PHP] File Upload Size Limits
I once had the same problem in a similar environment, but I never worked on it to fix it because it was sufficient for the given purpose. Later, I moved the script 1:1 (including php.ini) to a server running caudium as web server software and the problem was gone... Huh? Did anyone have any thoughts on this? I can upload an 8 MB file, but after that the upload fails. I am running PHP 4.0pl1 with Apache 1.3.14 on RedHat Linux 7.1. I am trying to do a file upload from the users PC to my web server. If I do a small file, the transfer goes fine. If I do a large file ( 50 MB), the transfer fails saying either the file was not available for reading or my script just bombs out. I need to be able to have people upload large files. I have changed the setting in php.ini to upload_max_filesize = 100M. Do I also need to change the following entries in php.ini? max_execution_time = 60 memory_limit = 8M Is this an apache limit? I'm not sure what to do with this as I really need to be able to transfer large files. mit freundlichen Gruessen / yours sincerely Gunther E.

Re: [PHP] Opening another page in code
I just want to open another page, sending some parameters, at a point
in a script - without the user clicking on anything (I can do this in
a form - I want to do it WITHOUT the form).
Like:if($test) {
GO_TO_PAGE (http://www.site.dom/page.php?id=838383);
}
Except with code that actually works, of course.
I tried header (Location:...) but got an error message that I can't
add to the headers.
If you HAVE to output other stuff first, you can't send a header because as the name
implies, a header should be at the top :-)
You can either include something like the following in the HTML page
META HTTP-EQUIV=Refresh CONTENT=10;
URL=http://www.htmlhelp.com/reference/html40/head/meta.html;
or do
some weird javascript stuff with an OnLoad event
or simply send
header(Location: http://www.php.net/manual/en/function.header.php;);
as the FIRST output of that page.

Re: [PHP] php stand alone
How do I compile php to work as a stand alone. Right now it is working thru the web but need to run it from a cron job. Have a look at http://www.php.net/manual/en/install.commandline.php The easiest thing of course would be to just call lynx (or any other command line browser taht is able to do a HTTP request and exit (that's why the -dump)) within your cron table, e.g.: 0 23 * * * lynx -dump localhost/path/to/some/php/robot.php /dev/null mit freundlichen Gruessen / yours sincerely Gunther E.

Re: [PHP] set var in PHP clarified
Jessica, I used that technique before PHP was available (for all readers, the key term here is Server Side Includes, e.g. http://httpd.apache.org/docs/howto/ssi.html.html). With PHP you're a lot more flexible so that you should get rid of your shtml structure, especially as PHP is much faster what really makes a difference if you've got many includes. For this simple example, the syntax is quite similar. In your main document, simply type: ?PHP $title=some title; include(/include/header.html); ? and in the header.html: title?PHP echo $title; ?/title That's it. But remember to either set *.html files to be parsed through PHP in your web server configuration or rename the main document to .php (or .php3 or .php4 or whatever your web server needs). Thanks for the prompt replies...but I think I should clarify... In regular html, I would do this: !--#set var=TITLE value=some title here-- !--#include virtual=/include/header.html -- and header.html would have in it (among other things): title!--#echo var=TITLE --/title So, the title of the webpage would be some title here... How can I accomplish the same thing in PHP? mit freundlichen Gruessen / yours sincerely Gunther E.

RE: [PHP] Batch job in UNIX.
But i want dont want to type in the password. I want to have the password in the command file. echo insert into... | ./mysql -p -u root test or cat filename | ... Perfectly right. And a mysql --help would have told you that you can call it (combined with the above) like this: echo insert into... | mysql -uroot -pwhitehat test or if you just don't want to type the mysql command parameters all the time, make yourself a shell script: #!/bin/bash mysql -uroot -pwhitehat test name it e.g. mymysql, make it executable and call echo insert into... | mymysql Have I missed the problem? mit freundlichen Gruessen / yours sincerely Gunther E.

Re: [PHP] Using PHP to test if server is online
I am writing a PHP script to test if the server on which it is running is
currently connected to the Internet. If so, the main page will display a
notice saying We are now online, else it will say Not connected
Any ideas on how to do this with PHP? I'm guessing it would involve some
kind of socket connection...
Yep. Simply open a socket connection as described in:
http://www.php.net/manual/en/function.fsockopen.php
I once wrote an RTSP (Real Time Streaming Protocol) link checker using that, works
flawlessly.
$sockethandle = fsockopen($host, $port);
if ($sockethandle) {
# Lets query document root
$query = GET / HTTP/1.0\n\n;
# Send the query
fputs($sockethandle, $query);
# Receive first line of response
$response = trim(fgets($sockethandle, 1024));
}
Remember, using fsockopen is more or less like telnet-ing to the server, standard HTTP
port is 80. But querying a web server can easier be done by doing a
file($url_of_server).
If it's just to tell if a server is online, nearly any method will do, including DNS
lookups or a simple system call with ping... :-)

[PHP] Expand/parse variables in file
All, This ought to be simple, but I can't crack it... I'm trying to read a plain text file where I embedded some variables. E.g. abc $a def Sucking this file in a string and setting $a to whatever results in abc $a def rather than abc whatever def. Where's the difference to directly doing the following: $a = whatever; $b = abc $a def; echo $b; which results in abc whatever def ??? What am I missing?
