Re: [PHP] php running as module or cgi?

I've done a little research and can't seem to find anything outstanding either way. Seems like as an Apache module is faster. This argument makes sense. CGI is more secure, this argument doesn't seem too persuasive to me. Maybe I'm missing something. Thanks As a module, any misbehaving script is running within the same space as all the other scripts. If a script is able to knock out PHP (for any reason), all the script go. With CGI, they are run in separate spaces. No direct communication (unless the scripts are sharing memory by some way). If a script knocks out PHP, that script dies. Everything else keeps on going. The main downside to CGI (as I understand things), is that for each invocation of the script, PHP has to do the complete build up and tear down every single time. For every single script. With FastCGI, when the server starts, a pool of ready to go php instances are created. So a script is called, the build up part is already done. In terms of speed, I'd guess you'd have to be working pretty hard to see the difference between module/isapi and fast-cgi. If I am not mistaken, An apache module can even bring down the whole web server if it really misbehaves. So this leaves the choice between CGI FatsCGI. CGI setup/teardown is only an issue for site with a fairly high traffic. It really depends on the type of site you intend to build. To me, the main security issue with mod_php in a virtual domain configuration is that it runs as the apache user and therefore any php code can read any files accessible to apache. If you have clients maintaining their own php code, they can access the code (and passwords and databases) of your other clients. I've never used cgi but I hope that it allows you to avoid this problem. Am I correct? --John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Running two versions of PHP locally
Scott Hurring wrote: You should be able to do that with PHP4 and PHP5. However, most people don't wnat to have to use php5 and php4 as file extensions but rather want to be able to say, everything on blah.com use php5 and everything on foo.org use php4... or even to specify differeing versions within a single host (on a per-directory basis) I would think you could do this on a domain-by-domain basis by using the AddType directive for that domain's root directory. But you would need to associate different 'types' for php4 and php5. It looks like 'application/x-httpd-php' is the default type for php4. Does php5 have a different type? Is there a way to explicitly assign a new type to a module? To be more explicit: When installing php5, what do I need to do to make this configuration work: VirtualHost *:80 ServerName myPhp4domain.com DocumentRoot /allmydomains/myPhp4domain ... Directory /allmydomains/myPhp4domain AddType application/x-httpd-php .php ... /Directory /VirtualHost VirtualHost *:80 ServerName myPhp5domain.com DocumentRoot /allmydomains/myPhp5domain ... Directory /allmydomains/myPhp5domain AddType application type assigned to php5 .php ... /Directory /VirtualHost If this is possible, it would be a much cleaner upgrade path than mixing a module and a cgi setup. After all, the goal is to be able to upgrade from php4 to php5, gradually, on a domain-by-domain or even page-by-page basis. Forcing a transition to cgi along with a transition to PHP5 compounds the complexity of the task. (I've never run under cgi, but it's my impression that module and cgi installations have some signifcantly different behaviors, not a transition that should be done without good reason.) After I started writing this Richard Lynch posted: Are you all saying you can't do that with PHP4 and PHP5? Why not? I think because the internal Apache/PHP hacks that made that possible in 3/4 are not as readily done in 4/5 Feel free to submit a patch, though if you think it can be done. :-) If this can't be done, I would think it would be a major impediment to the adoption of PHP5 at existing PHP4 installations. Someone (probably more proficient at C than I am) should be doing a patch. --John You can easily accomplish this by using PHP4 as a module and PHP5 as CGI (and i'm sure other ways as well, but ive only personally done it this way) It makes it very easy to selectively downgrade (or upgrade) depending on your needs without having to jump through file-naming hoops or proxy ports, etc...

John Wells wrote:
Personally, I get tired (and confused) when having to escape all of

you'd consider HEREDOC as an alternative approach:
Here's n idea I've had and never expressed publicly before. I wonder if
some of you haven't thought the same thing:
Why not develop a language syntax that has distinct open and close
string delimiters?
So (in an ideal world) the code in question
echo
td width=\25%\ align=\center\
a
href=\javascript:open_window('$php_self?action=view_recorduserid=$userid');\
view/a
a href=\$php_self?action=delete_recorduserid=$userid\
onclick=\return confirm('are you sure?');\delete/a/td
;
would be rendered something like this:
echo {
td width={25%} align={center}
a
href={javascript:open_window({$php_self?action=view_recorduserid=$userid});}
view/a
a href={$php_self?action=delete_recorduserid=$userid}
onclick={return confirm({are you sure?});}delete/a/td
};
or like this:
echo [
td width=[25%] align=[center]
a
href=[javascript:open_window([$php_self?action=view_recorduserid=$userid]);]
view/a
a href=[$php_self?action=delete_recorduserid=$userid]
onclick=[return confirm([are you sure?]);]delete/a/td
];
Of course, having separate characters for opening and closing double or
single quotes would work, but that would require changing the basic
ASCII set.
I believe some European languages use and as quotation marks.
What ASCII characters do they use?
I have seen some JavaScript code that uses curly braces to delimit a
string, but can't find that documented anywhere.
Thoughts anyone?

Yes, it's impossible. PHP is executed on the server. Javascript is executed in the browser. So Javascript cannot be called from PHP running on the server. PHP is a document generator. You can use it to generate Javascript the exact same way you use it to generate HTML. But the resulting Javascript won't be executed till it gets to the browser.

Re: [PHP] Possible?
René Fournier wrote: Simple problem: Many client apps need to send data to a server. By default each client will open a persistent TCP socket connection to a common IP address:port (10.10.10.10:1234) and write to it (which the server will save/log, etc.). My question is, what should be ready to listen at the IP:port? I was thinking of writing a PHP command-line socket server that listens at that port. But there will be a potentially huge number of clients connecting simultaneously (1000s), not transmitting a lot of data per se, but a lot of connections... Anyway, instead I thought writing a simple PHP script—say, listener.php—that gets executed by the web server and enters a socket_read loop until the client terminates the connection (set_time_limit(0)). Does this sound like a good way to do it? This way, Apache handles all the connections, and PHP is instantiated each time, but without having to fork processes, etc, and without having to do PHP CLI. Anyway, I've started looking at this, but I'm not quite sure if it's even possible. I mean, can something send a request to Apache, and continue to write data along that TCP socket? Normally, HTTP requests include GET or POST for such data, but this is not a a web browser that's opening the connection. Hope I'm somewhat clear. Just struggling through some options here Anyway, thanks in advance for any suggestions. ...Rene each client will open a persistent TCP socket connection to a common IP address:port (10.10.10.10:1234) (If you want simultaneous connections, each TCP connection will be to a different port.)

But a quick glance at your SQL shows that your second query returns all writings by all authors because you don't include anything to narrow it down to one author: WHERE Writings.ID = Writings.ID AND Author.Autholr_Name = Writings.Writings_Author AND Author.ID = Author.ID First of all: Writings.ID = Writings.ID and Author.ID = Author.ID are nonsense. Every query will match those crieria. In other words, you'd probably best take an hour or so to RTF 'Intro to SQL M.' Here's another hint: You have no PHP variable in your SQL query. That means you execute the same exact query every time you run it. So you will get the same exact results every time. So your solution is this: Include a PHP variable in your SQL query to specify which author you want to select. You probably want something like this: WHERE Author.Author_Name = Writings.Author_Name AND Author.ID = '$MySelectedAuthorID' (but remember to define $MySelectedAuthorId before running it :) Good luck and post again with your progress.

[PHP] Do I need to recompile Apache2 --with-apxs for PayPal PHP SDK?
I'm trying to install and configure PayPal Website Payments Pro using the PayPal PHP SDK. The first step in the SDK Quickstart instructions is: Enable Apache modules and APXS (Apache Extension Tool) In your Apache root directory, run: ../configure ?enable-mod=so --with-apxs /usr/local/apache/bin/apxs (sic) I think of the ./configure directive as a precursor to compiling with make, yet there is no mention made of running make. I'm running RHEL 4.1 with Apache 2 precompiled. I can see that modules are enabled, but I'm guessing it wasn't compiled with apxs since I just installed apxs 10 minutes ago. (FWIW, it's part of the httpd-devel package.) But, then, when I search the Apache site, I see no mention of a --with-apxs directive for Apache 2 (only for Apache 1.3). So I'm thinking the instructions may be a little off. Is there such a directive for Apache 2? So I'm wondering if this step is really necessary. I hate to futz with a perfectly fine Red Hat installation if it isn't. Does anyone know how PayPal uses apxs? Does it actually build its own module to be loaded into apache? If I proceed without recompiling Apache, how will I be able to tell if my existing installation of Apache is inadequate? Any help would be appreciated.

Re: [PHP] PHP Web Mail
Check with your hosting company. It's not that difficult for them to give you IMAP access also. You could write a server-based application that would retrieve your users' mail via POP3 and then store it in your users' home directory so it could be accessed from any computer via a web interface. But you would merely be reinventing IMAP!! --John On Monday 05 July 2004 02:22 pm, I.A. Gray wrote: Hi all, Thanks for all your info. The hosting company I use gives us POP3 accounts.

Hi Alicia. Welcome to the list. On Friday 11 June 2004 12:58 pm, Alicia Riggs wrote: Hi guys, I am new to this list, and signed up specifically for this problem. If any one has any ideas it would be greatly appreciated. I am writing a function to allow users from a specific intranet permission to view a directory. I am getting very different results from IE and Netscape. I have written this in JavaScript as well as PHP, and I am getting the same error in both languages. Are you talking about regular old (browser-based) Javascript? Javascript and (server-based) PHP are like apples and oranges. You can't really get the same error from each because they are doing completely different things in completely different places. When I use the gethostbyaddr call, in IE I get a domain name the majority of the time, with a few exceptions. When I use the gethostbyaddr call in Netscape I only receive a domain name if there is a DNS entry. If there is no DNS entry, Netscape returns an IP address. PHP functions are executed by the server. The browser (Netscape and IE) have nothing to do with them. gethostbyaddr is a simple reverse-DNS lookup (of the REMOTE_ADDR ip address) requested by your server to its nameserver. This never goes near the user's IE or Netscape browser. The IP address used is the one your webserver is using in its HTTP (TCP) connection with the browser (or its agent -- a firewall or proxy, for example). If there is no DNS entry for the ip address, there should be no hostname returned because by definition there is no host name to be returned. I am not sure what IE is using to get the domain names when there is no DNS entry. How do I get the correct info to be returned from Netscape? Here is the code I am using *** ?php //echo pre; //print_r($_SERVER); //echo /pre; $hn = gethostbyaddr($_SERVER['REMOTE_ADDR']); echo host by addr = . $hn . \nbr; $darr = explode(., $hn); $cnt = count($darr); $host = $darr[$cnt - 2] . . . $darr[$cnt - 1]; echo host = . $host . \nbr; /* if($host == xyz.com) header(Location: xyz.html); else if($host == abc.com) header(Location: abc.html); else header(Location: error.html); */ ? For debugging purposes, I would add more verbose echos: particularly for IP address and full host name returned ($hn). How are you deducing that you are getting different results based on the user's browser? Are there firewalls or web proxies involved? This could account for getting conflicting IP addresses for the same user reported by the browser (via Javascript) and server. Thanks in advance for any ideas!

If no to the above, then break the program down into

Re: [PHP] Newbie
Hi John-- Your name caught my eye, so I had to reply! Unfortunately I run PHP on Linux so can't be sure about your situation with Windex. But I think your problem is that you are opening your phpinfo.php file from your local file system. You should instead open it through your webserver. (i.e. enter your local domain name or IP address into your browser). To explain: phpinfo() is a PHP function that simply lists a lot of useful information about your PHP setup. But for it to be invoked, it must be run through the PHP interpreter. If you open it via your local file system, you bypass PHP. (When you installed Dreamweaver, it probably configured Winduhs to invoke DW whenever you open a .php file locally.) Hope this helps.

Re: [PHP] which is quicker? XML or database?
Hi Justin-- I've been wrestling with a similar problem.

It's actually perfectly fine XML. Nothing pseudo about it. I'd love to hear any opinions about which would form of data retrieval would cause less of a performance burden on the server. . . I've been wrestling with the same (or very similar) question: I'm trying to devise a flexible templating system where I can give my users control over content and inline formatting (allowing them to use, for example, p, em, span, ul) but retain control over page layout myself. It does seem to me that XML should play a role here, but I haven't been able to find the right XML tools. Ideally, the content would be stored in an XML document as you described. Your PHP page would use XPATH to address elements (or nodes) of the XML to set the value of PHP variables which would then be plugged into the HTML page. XPATH allows you to do that much. But every implementation of XPATH I've seen returns only the CDATA of an XML node, i.e. it strips out all the tags contained in the node. Thus you can't imbed formatting tags in the content. (I've been tempted to go ahead and do a quick and dirty system using a relational DB, but such a system would break down from complexity over time. You would need a new table for each set of page components [or else devise a very messy and unnormal system with one grand table of columns with multiple uses].) Am I missing something? Is there an implementation of xpath that does return the full contents of a node and not just the CDATA? I guess you could use regular top-level PHP to parse an XML document chracter by character, storing in an array pointers to the beginning and ending characters of each element (i.e. the first character following the start tag and the last character before the end tag). Then you could look up in the array each desired element and use substr() to read its value and set a PHP variable to it. Ideally, you would want a system that included a facility to edit the XML document as well as read it. This would be used in the user's interface for editing his content. I would think an easy first step would be to recreate (or reassemble) the XML document after each edit session. --John On Friday 13 June 2003 11:30 pm, Justin French wrote: Hi all, I'm looking at a site where there will be a lot of articles, all of which will be added once, and rarely edited again...

Re: [PHP] Please point me in the right direction
PHP is extremely easy for an experienced programmer to pick up quickly (assuming you know the basics of tcp/ip and web architecture). But experienced programmers also know the importance of the KISS principle. Why rewrite a system when you can port it? Kylix allows you to use Delphi on Linux. If it limits you to using Redhat 7.2, that should be no problem provided you apply all relevant security patches (which Redhat is pretty good at providing). In the meantime, start learning PHP. It is object oriented in its own way. When you are ready for a complete rewrite of the system, PHP may be all you need. A hybrid CGI/PHP system sounds unecessarily messy. (PHP can run in a CGI environment but is usually run in the more efficient Apache module environment.) The above is just my two cents' worth. I haven't used Kylix or Delphi, but believe both are descended from Borland's original (Turbo) Pascal. I've been programming since '72 but am new to PHP. I've been extremely gratified by how easy it's been to put together a relatively sophisticated system for a client in just a month or two after struggling for months to get Java and JSP to do much simpler tasks. --Frappy On Tuesday 25 March 2003 11:09 am, you wrote: Hi All, I have a CGI application written in Delphi web services and I want to port it to the Linux environment.
