[PHP] Postgres auto-commit
How can I disable auto-commit for a Postgres connection? Apparently server-side autocommit was thrown out in Postgres 8.0, and clients have to issue their own setting (which is sensible). The default is on (which I don't want). psql is apparently able to set or unset the AUTOCOMMIT option, but I found nothing similar for PHP. There is no ini setting for it. There is no function for it. Perhaps the options part of the connection string passed to pg_connect() might work, if I only knew what it's supposed to contain...

[PHP] gettext best practice
How do you people best deal with text meant for i18n via gettext, which is either large or contains HTML tags, or both? The GNU gettext manual, in section 3.2, recommends to split long texts at paragraph level, or in the case of long --help screens, in batches of 5-10 lines at most. I can dig this, but I'd still appreciate some feedback. Formatting, however, is a slightly different issue. The manual seems to have been written mainly for C users, and as such only deals with spaces, tabs and newlines. Of course, structural HTML is a big no-no IMO (ie. the likes of p, li or tables). But styling HTML is often needed (strong, em ...). Am I right in assuming that a small set of pure style-related HTML should be allowed? I'm thinking strong, em, del and ins. The alternative of replacing them with %s instead and inserting them in the code on the fly looks like an attrocity to me. And allowing any tags still doesn't make me 100% happy; consider borderline complications due to HTML vs XHTML, or the very principle of separating content from presentation, which seems to be breached. And how should br be dealt with? Allow it, or go with newlines instead, and decide in the code if I want to apply a nl2br() or not? -- Romanian Web Developers - http://ROWD.ORG -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Re: stream_set_timeout() stream_get_meta_data() etc...
Quoting Al [EMAIL PROTECTED]:
Darn, I left out an important function, the fread(). Code snip should be:
$fp= fopen(http://www.anything.com/foo.html, 'rb');
if(!fp) {do something different}
stream_set_timeout($fp, 2);
$contents= fread($fp, 20);
$status= stream_get_meta_data($fp);
if($status[timed_out] {do something};
It appears to me there is a basic logic problem. The script must get
past the fread() function before it gets to the stream_get_meta_data($fp).
But, it hangs up on fread() and the script times out.
Set the stream to non-blocking mode (stream_set_blocking). Now all
read functions will return instantly, regardless if any data came
through. You can test whether you got back anything by checking the
returned data. If you now read from the non-blocked stream in a cycle,
you will have no dead times and you will always retain control.
Only now can you rely on comparing time() with a control value set
before entering the cycle and decide to abort if a number of seconds
has passed.
stream_set_timeout() will be pretty much superfluous at this point
and may even hinder your reading from the stream.
Important tip: in a non-blocking cycle you MUST have an usleep()
somewhere. Otherwise that cycle will consume 100% CPU while it
runs. An usleep(1000) will suffice, adjust as needed.

Re: [PHP] Authentification related to browser window
Quoting Cristi Barladeanu [EMAIL PROTECTED]: My problem is pretty simple. User enters the site, logins, and after that he hits ctrl+n or something, to open a new window from same browser. Can I make him to login again in the new window but to keep him logged in the old one? Now i'm using sessions, but i realise that the cookies set by them are related to browser, so every window use them. You'll need to use URL session id's. I seem to recall that PHP sessions can be configured to use only them and never cookies. This way, the session id is passed as a GET parameter to every page you go to on your site. A new browser window won't have the id by default (if you go to the homepage) but it will if you do open this link in a new tab or new window. Session id's in the URL have a lot of downsides to them. First of all, you have to propagate them by hand. ALL links on your site must be careful to include them as GET parameters, and all POST forms must include them too. It's gets tedious very fast, and is error prone. Plus, it doesn't solve your problem 100%, as you can see above. If the new window is derived from an existing link they'll still seem already logged on. Finally, there are horrible security issues with URL sid's. The user may chose to save an URL containing a sid to his bookmarks, where they can be seen by someone else. They may send the URL (with the sid included) to a friend who may pass it on to others. The URL also gets passed to other sites in the Referer HTTP header.

The problem for Markus is that there's a limit to what kind of variables you can use directly inside strings. In particular, as he noticed, array elements referred by association ($_POST['Name']) won't work. Your workaround uses a trick: by not enclosing the element identificator (Name) in quotes, it is considered to be a constant. Since there's no constant with that name defined, it evaluates to the name of the constant, which is Name. This is bad practice; the manual page for constants specifically calls it that. And because you don't use quotes to delimitate the identificator, you don't have Markus's problem. The proper solution is to use string concatenation and thus place your variables outside of the string: $message = Name: .$_POST['Name']. Division: .$_POST['Division']. Phone: .$_POST['Phone']. Email: .$_POST['Email']; It's good habit to restrain yourself from both the above bad practices. Try to always use concatenation and specifically put variables outside of strings, and always use the quotes for array identificators.

And you can also used a php variable to detect multiple submit:
Even better would be using a token which you give to the user when the form

occasionally remembers a form submission page was in its window the last
time it was run, and tries to reload the page!)
In order to tackle reload issues, I prefer to use 3 scripts:
A: one to display the form
B: one to receive it through POST and process it (ie. send email)
C: one to display an OK or error message
Of course, depending on situation, two or more of the above can be the same
script behaving differently.
To avoid the reload problem, moving from step B to step C is done via:
header($_SERVER['SERVER_PROTOCOL'].' 303 See Other');
header('Location: C_script_here');
The 303 response forces the browser to use GET for the redirect location.
So no matter how many times the user reloads C they will only get the OK or
error message, no actuall re-processing is performed. And because the
redirect was done via HTTP 3xx code, not JavaScript, if the user uses BACK in
the browser they go directly to A. For all purposes, B is invisible to the
user.

A quick search on the error message cannot send headers will lead to loads of answers. Yet people still keep asking this question over and over. Some of the newbies can't really help it. It's somewhat non-intuitive to realise that session_start() will issue send HTTP headers, which in turn must be issued before regular output. Personally, I'd suggest always starting a script with ob_start(), this way the whole load of problems created by HTTP headers dissapears. -- Skippy - Romanian Web Developers - http://ROWD.ORG -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Use the strtr() to transform all occurances of similar characters to only one ie. becomes e. Then you can search for e and it will match. If you have special characters in the search string too, use the translation for it as well.

Re: [PHP] Re: How to make HTTP call to another address?
Quoting Arnout Boks [EMAIL PROTECTED]: Maybe it helps to open the address with the fopen( )- or file( )-function to read it's contents. I use this method to get data from (dynamic) html pages on another website. I don't have that much knowledge about Java servlets, so I don't know if this works for that also. It should work for any HTTP URL. But I'd recommend using fsockopen() instead of fopen(). fsockopen() has a built-in timeout, and you need this if you don't want to make your visitors wait indefinitely. The timeout works two-fold: there's a timeout for opening the socket, specified in the fsockopen() call; then there's a timeout control set with socket_set_timeout(). You can do something along these lines: * open socket with fsockopen() * if opening worked and it didn't time out, use socket_set_timeout() * do a while loop based on feof() and socket_get_status() (check for end-of-file and read timeout, respectively) * while in the loop, read from the socket A common pitfall: you will also get the HTTP response headers this way. Just skip everything at the top of the file until you meet a double newline (\n\n) for the first time. But you may want to check those headers to see if the server responded with a 200 OK code. The code is the first word on the first line of the response. Here's a nifty trick from the PHP-GTK crowd: use socket_set_blocking to set the stream to NON-blocking mode. Then all read calls to the socket will return immediately, regardless if they read something or not. In the long run, this will give the same results as with blocking mode, but you may save up a second or two due to increased responsiveness. Oh, and very IMPORTANT, do a small usleep() in every loop if you use non-blocking, even usleep(1000) will suffice; otherwise you risk killing the CPU on the server. -- Romanian Web Developers - http://ROWD.ORG -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] addslashes vs string unescape
I'm confronted with a somewhat weird problem and hopefully someone can make a
suggestion. I have to perform the following 3-step task:
Step 1. Someone provides a string (let's call it the formatting string) which
contains a PHP expression, which will apply a PHP function on another string,
let's call this one the random string. I don't control either the formatting
nor the random string.
Example of formatting string: trim('%val%')
Step 2. As you may have guessed, I have to insert the random string in the
formatting string before I can eval() the latter. So I need to replace %val%
with the random string. But I have to be careful, since the random string may
itself contain either double or single quotes, which will break the eval()
later. So I also need an addslashes().
Operations performed:
$for_eval=str_replace('%val%',addslashes($random),$format);
$for_eval='$final_result='.$for_eval.';';
eval($for_eval);
Step 3. After the above, I should have the formatted string in $final_result.
***
So now for the problem: addslashes() indiscriminately escapes with backslashes
both single and double quotes. Strings variables can be specified with either
single or double quotes; each of the cases, in turn, will not un-escape the
other type of quote. For example, a string enclosed in double quotes will not
un-escape \' and a string enclosed in single quotes will not un-escape \.
But my addslashes() escaped both types of quotes. And the formatting string
(see step 1) will necessarily have enclosed the string to be (%val%) in only
one of the two types of quotes. So, after all steps are performed, I may very
well be left with either single or double quotes still escaped, depending on
the type of quotes which were used in the formatting string.
I was under the impression that double quote strings will be interpreted as to
unescape single quotes too. However, the manual says they don't do that; they
unescape some common print sequences (such as tab or newline), double quotes
(of course), backslash itself, and octal or hexa expressions. NOT single quotes.
If only I could be sure of the type of quotes which were used in the
formatting string, I could only escape those by hand. But I can't be sure.
Also, I can't forcefully strip slashes from the final result, because I don't
know which sequences that look like escapes are really escapes or are just
legitimate pieces of string.
If only double quote strings would un-escape both types of quotes; they don't,
so their un-escape action is not a 100% reversion of the addslashes() effect.
Any ideas?

I've found another fairly reasonable solution: using $val instead of %val%. This way I don't need to ever show the actual contents of the random string in the eval() and the problem becomes void. I said fairly reasonable because it will still require a painful porting period and letting people know they should move to $val, but in the long run it will work. Here's a lesson about not testing well enough before deploying.
