Hey!
I'm just trying to replace some of the more bad words with their slightly
censored counterparts like so
$bad_words = array(/*Well you know the words so am not going to write them
here*/);
$bad_words_replacements = array(f*ck, f*cking);
$comment = str_replace($bad_words,$bad_words_replacements, $comment);
My question is this, for just two words its fine to use the above, but a pal
tells me that if using a lot of words (eg: 15) and the $comment is big then it
can take quite some time and be a bit of a processing strain as well because
php first checks the first word from the good list against all the 15 words in
the bad list against the comment then moves to the second word etc.
The above isn't fine since it will never work. The reason for that is
the fact that you enclose your array in quotes. This is something I've
never understood, I've seen tons of people do it, and to me it looks
like someone doesn't have a CLUE what he's doing. Why am I ranting about
this? This is why:
$some_string = 'this used to be an a, but is now also a b';
$bad_words = array('a','b');
echo str_replace($bad_words, 'something else', $some_string);
What does this mean ? If you remove all variables, you'll get:
echo str_replace('array', 'O', 'this used to be an a, but is now also a b');
And the result you'll get:
this used to be an a, but is now also a b
However, leaving away the quotes, since they're useless around a single
variable anyway (what, don't you think PHP knows the variable is a
string without you adding quotes around it?), like so:
echo str_replace(array('a','b'), 'O', 'this used to be an a, but is now
also a b');
you'll get:
this used to Oe On O, Out is now Olso O O
Hmm, there's a difference! :o
- Tul
P.S. IMO people should never write $var, if they REALLY want to cast
it to a string, do it explicitly like so: (string) $var; it keeps things
obvious and simple, not to mention working.

Instead of using str_replace, what about using preg_replace, which gives you a bit more control over the words that you are replacing, for example, only words on their own, etc. This will also let you get around deliberate mis-spellings of a profanity, such as 'fcuk', by using an expression like /f[uc]k/iw Obviously, this list could get pretty comprehensive, so like Andrew said, maybe you should look to see how some of the open source projects do it.

Do you want to cache the XSLT files themselves or do you want to cache the result of *applying* the XSLT files to the input XML? If you just want to cache the XSLT itself (e.g. loaded into a DOM document object) then there is little point as you would have to serialize and deserialize the dom document objects before storing them (via extending the class and adding __sleep() and __wakeup() methods) as I am pretty sure Dom Document doesn't do this automatically (last I checked which was admittedly a while ago!). This only saves a small amount of overhead. If you are looking for a good set of classes that can handle generic caching, I'd strongly recommend using the Zend_Cache system. http://www.framework.zend.com/manual/en/zend.cache.html Zend cache will support disk-based caching and memcache or APC too all via the same API.

Re: [PHP] Re: Interactive canvas example
JS I suppose. Though it creates a DIV element on demand. The function
in question is RGraph.Tooltip() in RGraph.common.js.
OK, I found it. Thank you for showing me. I was thinking of something
similar recently.
/**
* Shows a tooltip next to the mouse pointer
*
* @param text The tooltip text
* @return The tooltip object - a DIV
*/
RGraph.Tooltip = function (canvas, text, x, y)
{
/**
* Hide any currently shown tooltip
*/
if (RGraph.tooltip) {
RGraph.tooltip.style.display = 'none';
RGraph.tooltip = null;
}
/**
* Show a tool tip
*/
var obj = document.createElement('DIV');
obj.style.position= 'absolute'
obj.style.backgroundColor = '#E1';
obj.style.border = '1px solid #333';
obj.style.borderRight = '2px solid #333'; // Set the right and
bottom borders to be a little thicker - gives the effect of a drop
shadow
obj.style.borderBottom= '2px solid #333'; // Set the right and
bottom borders to be a little thicker - gives the effect of a drop

obj.style.display = 'block'
obj.style.visibility = 'visible';
obj.style.paddingLeft = '3px';
obj.style.paddingRight= '3px';
obj.style.fontFamily = 'Tahoma';
obj.style.fontSize= '10pt';
obj.innerHTML = text;
document.body.insertBefore(obj, canvas);
obj.style.left= (canvas.offsetLeft) + x + 3;
obj.style.top = (canvas.offsetTop + y) - obj.offsetHeight;
/**
* Install the function for hiding the tooltip.
*
* FIXME Not sure how this will affect any existing document.onclick
event
*/
document.body.onclick = function ()
{
RGraph.tooltip.style.display = 'none';
}
/**
* Keep a reference to the object
*/
RGraph.tooltip = obj;
}
Now I wonder why you are creating a new tooltip each time the user
clicks on the graph?
Why not do it the following way?
RGraph.Tooltip = function (canvas, text, x, y)
{
try {
if (RGraph.tooltip) { // if tooltip already drawn
RGraph.tooltip.innerHTML = text;
RGraph.tooltip.style.left = (canvas.offsetLeft) + x + 3;
RGraph.tooltip.style.top = (canvas.offsetTop + y) -
RGraph.tooltip.offsetHeight;
} else { // create tooltip if not drawn yet
var obj = document.createElement('DIV');

obj.style.backgroundColor = '#E1';
obj.style.border = '1px solid #333';

Re: [PHP] PHP XSLT caching
Thank you Col I will go into Zend_Cache as you suggested. One more thing- does Zend_Cache saces data into file or use a server memory?

I was thinkging about memcahce php(dunno if it will work on windows server and tbh never used it before). So i am sure that there must be several ways to cash xslt files. I google for this, but i am not sure that i found any solution i can use. What would be the best approach to solve this? I just would like to see more ideas :) LOL sure, if someone already have a good working solution i would appreciate any link or code :0) Well you have to define what you actually want to do do here as it's a little unclear from your description. Do you want to cache the XSLT files themselves or do you want to cache the result of *applying* the XSLT files to the input XML? If you just want to cache the XSLT itself (e.g. loaded into a DOM document object) then there is little point as you would have to serialize and deserialize the dom document objects before storing them (via extending the class and adding __sleep() and __wakeup() methods) as I am pretty sure Dom Document doesn't do this automatically (last I checked which was admittedly a while ago!). This only saves a small amount of overhead. If you are looking for a good set of classes that can handle generic caching, I'd strongly recommend using the Zend_Cache system. http://www.framework.zend.com/manual/en/zend.cache.html Zend cache will support disk-based caching and memcache or APC too all via the same API.

Very nice. Looks good on Kubuntu FF3.

Re: [PHP] Re: Interactive canvas example
Now I wonder why you are creating a new tooltip each time the user clicks on the graph? Why not? There's no need to cache it and it lessens the complexity if I don't. Why not do it the following way?

Ash www.ashleysheridan.co.uk The way Drupal handles such filtering is simple caching. As a policy we never filter general content on save, because we may want to change the filter format later and destroying user-submitted data is *not cool*. However, we do apply a number of possible filters on display (add line breaks, convert URLs to clickable, do bad word filtering, or any number of other things) and then just cache the result. The cache lookup (based on a hash of the string being filtered and the ID of the filter set to apply) is far faster than reapplying the filters every time. We've found this mechanism to scale very well. -- Larry Garfield [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Usually the database is just 10 MB, but when a search engine crawls our calendar, then the storage is quickly 108 MB. The system reports then mathematically correct: Space left on database -8MB !!! I plan therefore a web page, which is triggered by cron every hour and will just clear the table. Can I use just: mysql_query(DELETE FROM cash) or die(mysql_error()); If you really want to delete all rows, use truncate cash; otherwise the db deletes the entries row by row - which will be slow, and also it has to update all indexes on the tables as it is doing it. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] question about using sql server with php
i have a question about how to use sql database with php instead of using my
sql database
when i use my sql database the php code to connect to the my sql database is
=
$conn = mysql_connect($hostname, $user, $password);
if(!$conn)
{
echo Unable to connect to Database;
}
else
{
mysql_select_db($database, $conn);
$query = mysql_query($selectquery);
mysql_close($conn);
}
if i have to connect to a sql databse instead of my sql database as some
companies use sql database, how can i change the php code to connect, run a
query and close connection to the sql database.
apart from changing the code to connect to sql database is there something
else i need to do.
please advice.
thanks

You should print the results that you are looking for!
Are you looking for something like this?

[5] = Array
(
[1] = Array
(
[0] = some text

Re: [PHP] Dynamically creating multi-array field
No offense, but I thought it's obvious what I want to print.
print_r() shows null, and it should print what you just wrote = array field.
It works when first defining with eval():
eval('$tpl'.$node.'=array();');
I guess that's the only way.
Anyway, I appreciate your quick reply,

Nope, you have to use the eval() everytime for read/write.
