But Perl isn't going to *SEE* \\s !!!
PHP is going to *EAT* \\ and make \ out of it.
That's why \ is an escape character in PHP.
It's also an escape character in Perl/PCRE.
Some days I think PHP's escape character should have been | or
something, just so this topic wouldn't come up every damn month.
All true, except you would then end up having problems with regexs like
(this|or|that) :)

Personally, I have never used \\ in PCRE when looking for things like
spaces (\s), word boundraries (\b), etc. and it's all worked out fine.
It will work fine, but only because those (\s and \b) just happen to not
be special characters in PHP *at this time*.
It's sloppy programming because the backslash is known to be a special
character, and \s or \b could conceivably become special characters at
some time in the future. It's unlikely, but possible.
Not only that, but it makes it more likely that you'll forget and put \n
when you meant \\n, \r when you meant \\r, \t when you meant \\t, and so
on...
Also people thinking that PHP's single-quoted strings don't have any
escape sequences run into trouble when they have backslash as the last
character of the string:
$path = 'c:\';
This will give you parse error because the parser would think that you
wanted literal ' character and looks in vain for the string end. The
correct line should be:
$path = 'c:\\';

I don't explode the result of the ping.
If it was me, I'd try opening a socket connection to the host instead,
and check to see if you can connect or not. Whether or not that is
suitable to your application I don't know...

Hi!
I did following script:
?php
// Exec a ping
exec('ping -c 5 192.168.236.3',$result);
// Take result from icmp seq = 2
$icmp = strpos($result[2], 'time=');
$icmp = $icmp + 5;
$fin = strpos($result[2], 'ms');
// This is my end
$fin = $fin - $icmp;
// I take only the ms time
$text = substr($result[2],$icmp,$fin);
// Strip whitespace
$ms = trim($text);
if (!is_numeric($ms)) {
$a = '[EMAIL PROTECTED]';
$asunto = Servidor Caido;
$mensaje = Posible caida del servidor. No responde PING.;
mail($a, $asunto, $mensaje);
}
?
It's very simple, but i think that is working. I will add other options.

[PHP] how to know when a php library is installed
Hello all:
I need to test whether a library is installed with php or not. In this
case it's the tidy library I need for a project.
After getting a message from the hosting administrator that the tidy
library was installed and ready to use I ran a phpinfo() to find out
details:
There's nothing that looks like tidy in the Configure Command:

However there is a section in the phpinfo output that shows:
tidy
Tidy supportenabled
libTidy Build Date 1 July 2005
Directive Local Value Master Value
tidy.default_config no valueno value
Tidy Configuration DirectiveValue

I've tried to run this php code to call tidy functions:
?
$html = '
html xmlns=http://www.w3.org/1999/xhtml; xml:lang=en lang=en
headtitletitle/title/head
body
pparagraph bt /
text/p
/body/html
';
$tidy = new tidy;
$tidy-parseString($html);
$tidy-CleanRepair();
if ($tidy-errorBuffer) {
echo The following errors were detected:\n;
echo $tidy-errorBuffer;
}
?
And always get the error cannot instantiate nonexistent class.
Any input, comments are more than welcome,
Lizet

[PHP] Problem between php4.4 and mysql
Hi there, I discovered that our website was not working properly today (To my horror). Hosted on redhat enterprise 4. I think that there is a problem with php 4.4 talking to Apache mysql 4.1 as the php pages which do not talk to the DB are working but other php pages are working. I restarted apache using the inetd script as well as mysql using the inetd script. However the problem exists. I can enter mysql through the shell and tables seem intact. I have no relevant errors in my log file. One thing I noticed was that when I went to restart Apache it said ( before restarting): [Sun Aug 21 10:39:08 2005] [warn] module php4_module is already loaded, skipping Should I try to be loading that module, somehow? Any suggestions in how to get PHP working with mysql again would be much appreciated as it is a busy sight, so slightly stressed.

[PHP] Need help with for loop, pulling MySQL data, completely lost
Hello, all -
As a pet project of mine, I've decided to write a bit of code. This is
what I have, and it's not working as expected:
if ($action == prepareforupdate) {
@unlink(UPDATES/.$id./9.jpg);
$query0 = SELECT * FROM updates WHERE id=.$id.;
if (!$dbdata = mysql_query($query0)) {
echo Can't run query: .mysql_error();
die;
};
for ($i = 9; $i = 0; $i--) {
$j = $i - 1;
echo Getting ready to rename UPDATES/$id/$j.jpg to
UPDATES/$id/$i.jpg || nbsp;nbsp;nbsp;nbsp;br /;
@rename(UPDATES/$id/$j.jpg,UPDATES/$id/$i.jpg);
$returned = mysql_fetch_assoc($dbdata);
$query1 = UPDATE updates SET . $i . d = '
.$returned[$j.d]. ' WHERE id=' . $id . ';
if (!mysql_query($query1)) {
echo MySQL Error: .mysql_error();
};
}
}
I have a database in the following format. Let's say that d stands
for date, and t stands for times, and I have ten days' worth of
archives going on:
|id|1d|1t|2d|2t|3d|3t|...|8d|8t|9d|9t|
I'm trying to move the contents of the previous field to the logical
next field, so the value of field 8d becomes 9d, the value of 7t
becomes the value of 8t, and so on.
The problem that I'm having here is that only the first iteration of the
for loop work properly. Everything after that, is not being pulled up
properly, I suspect. This is what MySQL shows:
174 Query SELECT * FROM updates WHERE id=5

Re: [PHP] Need help with for loop, pulling MySQL data, completely lost
Dan,
When you run the second query ($query1), its results overwrite the
results of your first query ($query0). `mysql_fetch_assoc()'
returns results from the _most recent_ query, so after the first
iteration, the call to `mysql_fetch_assoc()' is returning results
from `query1', not from `query0'.
To solve this, retrieve all data from `query0' before iterating over
it. Sample code in /painstakingly exact/ PHP which I have tested
extensively:
?php
run query0
while( rows exist )
$rows[] = get next row
foreach $rows
for i = 0; i = 0; i-- {
build query1
run query1
}
?
Excellent description of your problem, by the way; this one's tricky
and definitely had me for a while when I first ran into it.

|id|1d|1t|2d|2t|3d|3t|...|8d|8t|9d|9t|
I'm trying to move the contents of the previous field to the
logical next field, so the value of field 8d becomes 9d, the
value of 7t becomes the value of 8t, and so on.
The problem that I'm having here is that only the first iteration
of the for loop work properly. Everything after that, is not being
pulled up properly, I suspect. This is what MySQL shows:

Re: [PHP] PHP and Prolog
I've never really examined the code behind the PHP/MySQL API, but I would assume, that it is mainly a wrapper for the C MySQL API. Do you know how to interact with this database in any other language such as C, Perl, Java etc? I don't know much about prolog, but a look at www.swi-prolog.org suggests that it has a two-way C interface. You'd exploit this, by writing a php Extension in C(see PHP manual), that would interact with your prolog app, using the two-way C/C++ interface. I don't know Prolog, nor anything about it, except that it seems to be a functional programming language, so take these comments in that reference frame.

Hello, Evan, and thanks for your reply -
I was under the impression that, since I specified $dbdata as the
argument to mysql_fetch_assoc(), that this would work exclusively with
query0. I'm a bit confused as to how query0's return is getting
overwritten, since I've tried to keep query0 and query1 seperate.
I'm going to drop this whole script, since I've found a much better way
of keeping records of updates involving one big-ass database, but I'd at
least like to know what I did wrong in this instance, so that I at least
learn something. Your explanation was very helpful, but please clarify,

[PHP] Resizing thumbnails to the browser

I'm wondering if anyone can point me at some code that would achieve this? All of the thumbnails are in jpg format.

That doesn't tell you if $mydata-email contains something. It tells you
whether the value of $mydata-email, when cast to boolean, equals TRUE.
If $mydata-email equaled zero or the string 0, it would still contain
something, but that if statement would not get executed.
In MySQL, it would depend on the datatype. You could do any of the
following, depending on what you actually want to do:
colname''
colname0
colname IS NOT NULL
Or, if you're in MySQL = 5.0.2 and are using true boolean values:
colname IS TRUE
or, if you just want to check if it's TRUE or UNKNOWN:
colname IS NOT FALSE

So, essentially, I'm trying to resize the thumbnails down to 140px wide while maintaining the aspect ratio of the image's height. The scaling is easy. It's getting the damn browsers not to screw up that's hard :-) Actually, a cheap and easy way would be to just use: img src=/image150.jpg width=140 The penalties are: 1. The browser downloads a 150x??? image which is a TINY bit larger than 140x???, but, really, this is negligible. 2. The browser has to scale the image, and that's slow if it's a really really old slow computer. But, to do it right server-side. 1. Edit a .htaccess file and add this to it: Files thumbnail ForceType application/x-httpd-php /Files This informs Apache that your 'thumbnail' file is REALLY a PHP file, even without the .php on the end. 2. Put this in 'thumbnail': ?php //Untested... $path = /full/hard/drive/directory/path/to/your/images/; $image = imagecreatefromjpeg(filename($path . $_SERVER['PATH_INFO'])); $width = imagesx($image); $height = imagesy($image); $new_width = 140; $new_height = round(140 * $height/$width); $new_image = imagecreatetruecolor($new_width, $new_height); // resource dst_image, resource src_image, int dst_x, int dst_y, int src_x, int src_y, int dst_w, int dst_h, int src_w, int src_h imagecopyresamples($new_image, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height); ob_start(); imagejpeg($new_image); $data = ob_get_contents(); ob_end_clean(); header(Content-type: image/jpeg); header(Content-length: . strlen($data)); echo $data; ? Now, to use this script, make an IMG tag like: img src=thumbnail/original150image.jpg width=140 The browser will never know the image is dynamic, nor that you are using PHP, and that's the way you want it. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Should I just not bother closing the connection, letting PHP deal with it - the object will not attempt to re-use the stale connection because it will get a new instance courtesy of __wakeup when unserialized. The persistence is all on the MySQL side -- From PHP's perspective, it's more like a re-usable or a return for deposit connection :-) When you close the persistent connection, MySQL still keeps around the data structures to re-use it for the next script, which is what persistent really means. You don't have to close the connection -- PHP *is* going to close it for you as the script ends. When the same process (Apache child) asks for a connection with the same username/password from MySQL, MySQL can re-use the existing data structures to save the time of building them. That time is actually rather expensive, as it involves a lot of buffers, structures, and, I believe, a fair amount of resource-locking to be sure the current connection will not be in a race condition with other connections for things like mysql_insert_id() and, if you use innoDB, transactions. So saving this time for MySQL to build a connection from scratch instead of using the parts laying around from the last one is the persistent connection. HTH NOTE: Be sure you have a few *more* max_connections in /etc/my.cnf than the number of Apache MaxChildren -- Otherwise your Apache children can lock up all the MySQL persistent connections and leave you with Apache children starved for MySQL connection, as well as NO WAY for you to use mysqladmin or mysqldump since *ALL* the available connections are taken up by your Apache server.
