I really think this already exists. You should probably search a bit
harder.
Maybe there are good standalone-link-checkers, but I need to integrate
it in an application and my customer has some special wishes. Anyways I
finished writing the link-checker.
A thing which seemed a bit confusing to me is that if I open a
non-existing website (fopen('http://www.amazon.de/nonsensestuff')) I
always get an error message Success. It's the same thing if I use
file(). The manual explains that fopen() returns false if the website
could not be opened, that's why I don't know why this error message
appears? Besides this Success-message is surely a very bad error
message. I use PHP 4.2.3.

To actually check on the HTTP status codes you need to run your own, either
using cURL, or by doing your own stuff using fsockopen().
I tried using fsockopen(), but still experience a problem, I want to use
the following script to retrieve both, the headers and the actual file:
You need to transmit the Host: header so the web server has a chance to
know which virtual host you want to reach. Ideally you would also tell the
server what type of content you can handle (see below). Also note that the
correct line ending for MIME headers is always CRLF (\r\n):
$hostname = 'www.example.com';
$file = '/index.php';
$ip = gethostbyname($hostname);
$fp = fsockopen($ip, 80, $errno, $errstr);
if ($fp)
{
fputs( $fp, GET .$file. HTTP/1.0\r\n .
Host: $hostname\r\n .
Accept: text/html\r\n .
Accept: text/plain\r\n\r\n );
$src = '';
while (!feof ($fp))
$src .= fgets($fp, 4096);
fclose ($fp);
}
This will get you the whole page, including all headers.
Thank you! This works fine. I can use this for reading the HTTP-Status.

implode('',file($url)); // or file_get_contents()
Now I'd like to find out which file was really retrieved, for instance
http://www.example.com/index.html. Is this possible and how?
Background:
I need to write a small link-checker (Intranet), which reads in all
links within a file and then looks if they're broken and collects some
information. Unfortunately I didn't find a simple, free link-checker
that's why I write my own. It would be good to find out the complete
url, because I want to collect the file-endings (.php,.html, ...).
Another thing is that my script is recursive, so I need a function
absolute_link() which takes a (possibly relative) path and an url to
find out which page to go next.
Example:
$url = http://www.example.com/foo/bar/
Somewhere in the source code:
... a href=../articles/page.html / ...
My script reads in $path='../articles/page.html'. The function
absolute_link($url, $path) should return
'http://www.example.com/foo/articles/page.html'. However $url could be
http://www.example.com/foo/bar (bar can be file or dir here imho) or
http://www.example.com/foo/bar/index.php and in any case absolute_link()
should return the same. Of course this function is easier to implement
if I always have something like
http://www.example.com/foo/bar/index.php. Maybe there's already a useful
function besides parse-url() I can use here.

[PHP] Cleaning up HTML table structure
The following problem seems to be hard to solve: A PHP-Script reads in an HTML-File and removes linebreaks, tabs and not needed spaces. After that the script should reconstruct the table-structure this way (example): table ... tr ... td ... table ... tr ... td ... ... /td td ... ... /td /tr /table /td /tr /table The next thing is that lines longer than for instance 80 chars ($maxlength) should be split up into several lines. Is there any good way to solve this? Regular expressions seem to be of limited use because the recursion of tables can be infinitely deep and the lines between td and /td must not not be longer than $maxlength and should have the appropriate number of spaces before it. Stepping through the string (the whole file is a string) with simple String-functions is very complicated either. I hope you can give me some hints how to find a (simple) solution for this problem.

[PHP] RegExp for Forum-List-Code
Hi out there,

[list]
[*] item 1
[*] item 2
[*] item 3

should be converted to
ul
liitem 1/li

/ul
Now I need a Regexp for converting every [*] foo to lifoo/li.
I started with
$text = preq_replace('/\[\*\]([^(\[\*\])]*)/i','li$1/li',$text);
The RegExp starts from [*] and saves every char in $1 until [*]
occurs again. That's fine, but what I need is a RegExp which starts
from [*] and saves every char in $1 until [*] OR /ul occurs in
$text. I tested a lot, but didn't find a solution. I'd be glad about
any help.

Re: [PHP] ini_set('register_globals',0) doesn't work
Thank you for answer. I didn't expect ini_set('register_globals','Off') to
work, that's why I had a look at the documentation. There should be
PHP_INI_PERDIR, PHP_INI_SYSTEM but not PHP_INI_ALL
in the table (so it's a mistake in the documentation).
Anyway it may be possible to use this, if the variables are unset. This
is overload of course, because the variables are first set (because of
register_globals=On in php.ini) and are unset if I call
ini_set('register_globals','Off'), but this could be a nice feature,
making it easier to work with register_globals=Off while other
old projects still work. Do you consider this a good idea? Does
anything except performance speak against doing this manually?
Jens
register_globals affects things that happen before PHP parsing begins, so
by the time you get to your ini_set() it is too late. So no, that won't
work. You need to set it in your php.ini, httpd.conf or .htaccess.

Well, I'm not sure, because I think we're talking at cross purposes. I'm *still* not sure what you want gmtime() to achieve that's different from time(), because, as far as I can see, the two scenarios you describe above actually return the same value. Or, to put it another way, because a timestamp is *always in GMT*, it returns the time since 1-Jan-1970 00:00:00, full stop, period, end of story. In other words, timestamps operate in a single timezone, and it's up to anything else that works with a timestamp to do the timezone (and daylight-savings) corrections. (This is also why you get the anomaly of 23- and 25-hour days in areas which have daylight-savings timeshifts.) Let's take some detailed examples, and maybe you can explain what you're trying to get with your gmtime() (and why!): In a purely GMT zone, with local time 27-May-2002 12:00:00, the UNIX timestamp is 1022500800. In a nominally GMT zone, but with daylight-savings in effect (such as British Summer Time!), with local time 27-May-2002 13:00:00, the UNIX time stamp for this is also 1022500800. Likewise, in a GMT+0200 zone, a local time of 27-May-2002 14:00:00 also gives a timestamp of 1022500800. In fact, this same timestamp of 1022500800 also represents all of these local times: 27-May-2002 04:00 -0800 27-May-2002 07:00 -0500 27-May-2002 17:00 +0500 27-May-2002 23:00 +1100 and even such oddities as: 27-May-2002 21:30 (Western Australia / Northern Territory) Thus, given the timestamp of 1022500800, it's the job of date() to determine the correct timezone and daylight-savings offset and apply them before formatting the output; gmdate() just formats it without applying any offsets. Likewise, mkdate() and gmmkdate() translate the other way respectively with and without timezone correction. Forgive me if I've gone on at what seems like excessive length, but I just wanted to make sure we both know exactly what it is we're talking about! Cheers!

(I used the Windows installer anyway and have again carefully followed the changes needed to the INI file.) Still the problem. A PHP FAQ says that if you get a 500 error (internatl config problem) it is worth testing with the command line: php.exe -i so I did this in DOS. Reams of HTML stuff whizzed by. According to the FAQ answer this means PHP is OK. So back to Apache. But that is as above. I tried Netscape version 2 and IE6 - both give the same answer. So it is not the browser because I have tried different ones. It is not PHP because on the command line that works OK and shows PHPINFO stuff. It is not Apache because it says it is running in the browser windows when you call localhost. So - I am being driven slowly nuts with frustration. May I ask for any ideas? (I should add that I am a rank amateur trying to do all this so please take it slowly).

[PHP] gmtime?
Any reasons why there's no gmtime()-function in PHP? I'd like to hear your thoughts. Jens Lehmann -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] gmtime?
Did you see gmdate()? http://www.php.net/manual/en/function.gmdate.php Yes, of course. I can do time()-date(Z) to have gmtime (or maybe) something better, but wouldn't it be better to have gmtime() implemented anyways? Please tell me if I missed something. Thank you. Jens Lehmann PS: date(U) and gmdate(U) return the same results -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] gmtime?
I don't know what gmtime() is supposed to do. But is gmmktime() similar? time() returns the number of seconds since the Unix Epoch to the current local time gmtime() should return the number of seconds since the Unix Epoch to the current GM-time Do you understand now? gmmktime() does exactly what I want if I don't pass arguments but since this behaviour is not documented it's probably confusing to a lot of people, isn't it?

[PHP] Re: accessing a mysql column by number
Is there a way to access a column in Mysql just by using a number? Please refer to the MySQL-Documentation. A database doesn't have any predefined structure, so you're responsible for doing this. Can you explain why you need this feature? Like if you had three columns called column1, column2, and column3 and I wanted to access column3 just by using the number 3 This could simply be done by using prefixes: $col = $prefix.$number Jens -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: accessing a mysql column by number
Hi Rick, thanks for correcting me. (numeric order) I thought he just wants to select one col. (SELECT 3rd column FROM table ... ) I didn't read your answer because it was not in the same thread (reading the news with MS Outlook Express), because the subject-line changed. Can you suggest me a newsreader which can manage this? I assume this is the wrong place to ask, so if you don't want to answer, please tell me where to find the answer. (I didn't find it in any FAQs.) Sorry for asking such a stupid question. Jens Jens, A database does have a structure. The order in which the columns/fields are defined is their numeric order. Second, mysql_fetch_row() will accomplish what he needs. Third, we answered this yesterday. -Original Message- From: Jens Lehmann [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 28, 2002 8:18 AM To: [EMAIL PROTECTED] Subject: [PHP] Re: accessing a mysql column by number Is there a way to access a column in Mysql just by using a number?
