Yes. It matches any character based on the latin 'a' that is not
followed by an 'e'. It keeps the pattern from matching the 'a' when it
immediately precedes an 'e' for the character 'ae' for words like
these:

I was intrigued by your example, so I played around with it some more

highlighting search terms, but none that I found did what you're
after. (I admit I didn't look very deep.) I was up to something like
this before your reply came in. It's still by no means complete. It
even handles simple English plurals (words ending in 's' or 'es'), but
not variations that require changing the word base (like 'daisy' to
'daisies').
?php
function highlight_search_terms($phrase, $string) {
$non_letter_chars = '/[^\pL]/iu';
$words = preg_split($non_letter_chars, $phrase);
$search_words = array();
foreach ($words as $word) {
if (strlen($word) 2 !preg_match($non_letter_chars, $word)) {
$search_words[] = $word;
}
}

RE: [PHP] Math Weirdness
On 14 July 2008 20:47, tedd advised: Round-off errors normally don't enter into things unless your doing multiplication and division operations. At that point, what you get back from the operation is an approximation and not the actual number. Bull! Nearly all computer floating point numbers are approximations because of being held in binary rather than decimal. Any number with a (decimal) fractional part that doesn't end with the digit 5 is necessarily an approximation, and that's only half the story. So as soon as you involve numbers like 0.1 or 0.2, you've already got minor inaccuracies which will propagate through any kind of arithmetic -- it's just worse with multiplication or division because these tend to result in inaccuracy in more significant digits! Bottom line: a floating point value should *always* be treated with an appropriate degree of suspicion. Cheers!

The original problem may just have been that the /usr/local file system was mounted read-only after the power outage (perhaps due to some disk corruption caused by the failure?). Since then you have reinstalled apache, but possibly not in the place your PHP script expects it to be. That would be my first thing to check... This sounds really dumb, but it turned out that I have some inconsistencies going on in my httpd.conf file. Now I have changed both groups to daemon, and changed to owners as Rob suggested. Now it is finally working fine. Would I still need to change everything back to 0755? Or, should I ask, what is the appropriate permission I should be using here? Alice At least that explains why the problem arose from a power failure: you had some new settings in the configuration which needed an apache restart to make them happen, and when the server rebooted, apache picked up the new settings... The problem is that if you did chmod -R 777 /var, you changed every file /var and ALL of its subdirectories to have 777 permissions, and there's not an easy way

Yes. It matches any character based on the latin 'a' that is not

[PHP] DB search and case sensitive comparison
Hi all,
I have a question and I can't seem to get around the problem or finding a
total solution.
I have a DB with a list of entries, one of the tables has fields and one of
the fields is called the lookup_string field.
This field is used to checkup values when users enter the site (explained
below).
So basically what happens is that the user will enter the site and I will
get their user agent from the $_SERVER variable.
What I want to do is to find out which entries in the DB are present in the
useragent string.
Eg:
lookup_string (in db): Mozilla
useragent: 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.15)
Gecko/20080623 Firefox/2.0.0.15'
So what I did was I used the locate function in my mysql query which gives
me the correct result set.
Now what I need to do is to ensure that the lookup_string is in the
useragent string and the CASE is the same: IE: Mozilla and not MOZILLA or
mozilla etc...
I am using the following If (however it fails because its part of the
useragent string and not the whole complete string therefore providing a
mismatch).
if(strcmp($userAgent, $lookup_string)==0){
//matches
}
Else
{
//doesn't match
}
Which way could I accomplish searching for the lookup_string in the
useragent and that it's the correct case?
Thanks in advance.

strpos(), ereg() or preg_match() should work, take your pick. strpos()
most likely faster for this simple match.

So as soon as you involve numbers like 0.1 or 0.2, you've already got minor inaccuracies which will propagate through any kind of arithmetic -- it's just worse with multiplication or division because these tend to result in inaccuracy in more significant digits! Bottom line: a floating point value should *always* be treated with an appropriate degree of suspicion. Cheers! Mike Mike: No reason to be rude. I said: Round-off errors normally don't enter into things unless your doing multiplication and division operations. And that is not Bull -- it's true. You can add and subtract all the floating point numbers (the one's we are talking about here) you want without any rounding errors whatsoever. Sorry, I do apologise if I came over too strongly -- there was no intention to offend. However, you really can't dismiss the effects of round-off errors on addition and subtraction as lightly as that. It's simply not true that approximations only occur at the point of doing multiplication and division -- there *are* approximations involved in addition and subtraction, and it is necessary to be aware that this is the case -- as Jay proved, 0.1+0.2 is hardly ever exactly 0.3. In this sort of case, it may well be that an appropriate degree of suspicion is simply to round to 2 decimal places at every stage, or compare the absolute difference to .001, but nonetheless one has to *know* that this is necessary.

The setcookie line needs to come before you output anything. Move your html
output at the top past it, and you should be good.

I said that if all he was doing was adding and subtracting, then he wouldn't have any problems -- those operations are not subject to the rounding errors that division and multiplication induce. And experience has shown me that my claim is true. I can add and subtract dollars and cents all day without an error whatsoever. Now, if you get into more complicated math, such as multiplication/division then of course rounding errors come into play much more noticeably. It is true that not every number can be represented in binary because of the limits of the processor. Take for example pi, no computer in the world has capabilities to represent that number in it's totality (i.e., unlimited precision). However, if one defines the precision, then that's a different matter. As with the OP's problem, the precision he was dealing with was simply 0.00 and addition and subtraction operations don't come into play at the precision level (i.e., 0.10 + 0.20 will equal 0.30 no matter how many times you add it). In addition, the algorithm that used to round the number also comes into play. For example php always round down and that introduces bias, as proved here: http://webbytedd.com/bbb/rounding/ So, all in all, I agree with your statements, but I just don't think you fully appreciated what I was trying to communicate to the OP.

It is true that not every number can be represented in binary because of the limits of the processor. Take for example pi, no computer in the world has capabilities to represent that number in it's totality (i.e., unlimited precision). Umm... here it is to unlimited precision: π Cheers, Rob. -- http://www.interjinn.com Application and Templating Framework for PHP -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] mkdir permission errors
Nope, I have set mine to 755, and it does not seem to be giving me any errors. This is the safer way to do it, right? Alice Alice, At this point, you need to re-install the OS or prepare to get your machine completely hacked and trashed. With your permissions that badly screwed up, it is only a matter of time before someone finds it and has their own ghost server. First, go pick up a System Admin book for Redhat Second, READ IT, Especially the parts on permissions and changing users Third, Re-install the OS Fourth, read the CLI vs. HTTP differences on programming languages you are using. Obviously Perl and PHP are going to give you the same errors when using the HTTP and will operate differently from the CLI unless running as the same user. This might even help your schooling. Hopefully your classroom exercises are further along then these basic principles, but if not I have severe doubts in anyone graduating with an MIS from Indiana University.

It looks like the array is sorted.

Re: [PHP] case and accent - insensitive regular expression?
The original problem was User X submits a character string A. A PHP scripts uses A to search for it's occurences in a DB, ignoring special characters. The result of ze search is a list of character strings M-LIST with matches. This list gets outputted to the user X, but before that all the matching strings should be replaced with 'span style=color: #FF'..'/span' If i clearly got the OP then he is using MySQL to perform the search. I guess he is doing it with MATCH. So MySQL already found the match and in PHP it has to be done again ... eg. The table has 2 entries, string1 and string2 .. string1 = 'Thís ís an éxámplè stríng wíth áccénts.' string2 = 'This is an example string without accents.' Now the user searches for ample: search = '*ample*' Both string have matches due to accent-insensitivity (AI).

Especially a locate function got my interest. http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_locate Now shouldnt it be possible to create a query that searches the db for matches and additionally uses the string function? I have no idea, but maybe some MySQL-expert out there has ... Yeti There are definitely possibilities there. Personally, I tend to be biased against using the database to format output for presentation, so I'd rather not push the task off there. Still, I know lots of developers do not share this bias, so I'll address a couple other issues I see with this approach: 1) If the search word appears multiple times, LOCATE() will only find it once. I'd probably use REPLACE() instead. This leads to the next problem: 2) I'm not sure if the OP wants this or not, but if he wants to highlight each of multiple search terms the way many sites do, he would have to split the terms and build a SQL phrase that like this (there are probably other approaches available in MySQL to do the same thing): -- search phrase 'quaint french cafe' SELECT REPLACE(REPLACE(REPLACE(`my_column`, 'quaint', 'span class=keysearchquaint/span'), 'french', 'span class=keysearchfrench/span'), 'cafe', 'span class=keysearchcafe/span') FROM ... In this case, he should get all instances of each word highlighted, but the accented characters would again be replaced with a particular style. (Not to mention the size and complexity of the query being passed from PHP to the database or the potential size of the result being passed from the database to PHP since it now could have lots of formatting text embedded in it.)

[PHP] is there a problem with php script pulling HTML out of database as it writes the page??
Hello. Again, I'm fairly new to php so please forgive me if my question is a very simple or obvious one. I've just tried testing for the first time some php code that is pulling text out of a database to print it on the webpage. Some of this text includes HTML, specifically in this case an img src=x statement. Much to my surprise, this is not working. Is there a problem with pulling HTML out of a database like this as the page is being written? There's no problem of course if my php code is writing the HTML to the page - in this case, the img src=xx statement works fine and the image is displayed. Why is it a problem when my php script pulls the HTML code out of a database and writes it to the page from there?? It would appear that when my php script writes HTML to the page a process of some kind is executed to, in this case, get the image and put it on the page. Apparently this same process is NOT executed if the HTML is retrieved from a database and simply written to the page from there. Is this correct? And, if it is, can anyone suggest a workaround, another way to get done what I'm trying to do here? Thanks for any help you can give me.

Re: [PHP] is there a problem with php script pulling HTML out of database as it writes the page??
Yes, here's the code that is retrieving news items from the database
and printing them on the page (I do some other stuff with the text
before, and after, I print it, for example, find the sentences, so I can
print complete sentences, and not just pieces of sentences). As I say,
occasionally these news items contain some HTML, e.g., the img
src=xxx statement. All of the text is being correctly retrieved
from the database and written to the page, including the img
src=xxx statement, because I see it all in the page source of the
page in my browser. However, the img src= statement is NOT
working, that is, the image does NOT appear on the page.

Sorry, I'm back again with this same problem! Apparently the only
reason it looked like it was solved an hour ago was because the img
src=xx statement I tried reading out of the database was pointing
to an image already on the page!
When the img src=xxx statement points to an image NOT already on
the page, it doesn't work.
I thought the size of the image might be the problem, but no matter how
small I make the image, it doesn't work.

OK. Once again, a problem I thought was abstruse and formidable turns
out to be ridiculously simple and embarrassingly obvious (once you
realize what it is - image not in web server directory!!!) But I
didn't know until this happened that the browser sends a follow-up
request to the web server for the images it finds specified on the
page. This is a very useful piece of knowledge!! It made it obvious
that I was looking for the problem in all the wrong places! Sorry for

It would appear that when my php script writes HTML to the page a
process of some kind is executed to, in this case, get the image and
put it on the page. Apparently this same process is NOT executed if
the HTML is retrieved from a database and simply written to the page
from there. Is this correct? And, if it is, can anyone suggest a
workaround, another way to get done what I'm
Re: [PHP] Changing PHP.ini
By visiting php.info in a web browser I have confirmed the location of my php.ini file as /usr/local/php5/lib/php.ini. I open that file and edit the line: ; - display_errors = Off and change it to display_errors = On I then retstart Appache and visit php.info which still reports display_errors = Off. What else can I do? Should be simple: create a script with the following code: ?php phpinfo(); ? Then open that script in your browser. The generated output does also provide information about the path of the loaded php.ini. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Downloading a file
I am having trouble getting a file to download to work in Internet Explorer.
The site works fine in FireFox. The page retrieves the contents of a file
from a database and outputs the following
?PHP
header(Content-type: application/octet-stream);
header(Content-Disposition: attachment; filename=\{$data['filename']}\);
header(Content-Description: PHP Generated Data);
echo $data['file'];
?
Where $data['filename'] is the name of the file as stored in the database
and $data['file'] is the contents of the file. The script used to download
the file is called view.php. As I mentioned, this works great in FireFox
but with Internet Explorer, I get the following error:
Internet Explorer cannot download view.php from www.yourdomain.com.
Internet Explorer was not able to open this Internet site. The requested
site is either unavailable or cannot be found. Please try again later.
Any help would be greatly appreciated.
