Another technique could be.
$s = $mydata->restored;
if($s[0]==$s[1]
&& $s[1]==$s[2]
&& $s[2]==$s[3]
&& $s[3]==0){
do_work();
}
But I think you got the best solution already.

maybe another way can be
$str = explode('-',$mydata->restored);
if($str[0] == '0000') { dostuff();}
;)

Overkill?
<?php
$o[] = '0942-23-23';
$o[] = '0000-00-00';
$o[] = '1238-00-00';
$o[] = '0001-23-45';
$o[] = '0000-11-22';
$now = microtime();
for($i=0;$i<count($o);$i++) {
if(preg_match('/^[0]{4,}\-/U',$o[$i])) {
//echo "Offset #".$i." matches: ".$o[$i].PHP_EOL;
}
}
echo (microtime(1) - $now)."\n";
$later = microtime();
for($i=0;$i<count($o);$i++) {
if(substr($o[$i],0,4) == "0000") {
//echo "Offset #".$i." matches: ".$o[$i].PHP_EOL;
}
}
echo (microtime(1) - $later)."\n";
?>
Sample Output:
1264522257.0001
1264522257
The preg_match() method, which is more expandable and adaptable
than relying on static position, took less than one-ten-thousandths of
a second longer to calculate than substr().
Just an FYI before you start worshipping pasta, Mr. Vincent. ;-P

Not yet! I'm on windows and I'm not confident enough to put extensions
I've built out on the live servers.
Also, it is using VC8 and I'm on 5.3 (VC9, x86, nts). So not tested.

HI Angus,
+1 I agree on what Paul already said .
As in fact you were just to sent out low volume mails.
Create a table and queue all pending mails in that then use windows
scheduled tasks to perform the actual work
if that is not a real-time mail.
One thing to note, php on windows does't support specify username and
password.
But only hostname / IP Address and port only.
I can not help much
but just few more suggesions.
Hope these help
Eric,
Regards,

As another option, I have a simple SMTP script (Perl) that listens on
port 25, accepts all forwarded messages and appends them to a text file.
Since it doesn't actually do anything, it is all but instantaneous. I
use it as a black hole relay MTA for development and test servers that
can't reach the real world. If anyone is interested, let me know and I
can send you a copy. It is adapted from something I found via Google.

With a constant, PhpDoc will pick up the value of the constant and
incorporate it into the documentation.
With a method, there is no way to know the return value. The type,
sure, but not the value.
Setting a constant is by far the simplest way to deal with this.
A method to return a constant is one method unneeded.
But, as I've said, I completely missed defined().
That's all I needed.
If the kill interface is applied to a class, then the parent class can
quite happily use defined(get_called_class() . '::KILL_SWITCH_SET') to
see if the class is defunct (or whatever).
Really. It was just the defined() call I missed. Everything is now working fine.

Hello list :)
I have this problem, a certain string can contain the following information:

What I want is to be able to get this result:

(the order of appearance doesn't matter)
Is it even possible to do this with regular expressions? Or should I first
look if there is some kind of match and then apply an
str_replace($match,'',$string) and add the $match again?
Greetings !
Assuming the duplicate segments are identical.....
I'd use explode() and convert the string to an array. Use "}" for the delimiter.
Then use array_unique()
And then use implode() to restore the string.

Just did a bit of hunting as I know I've seen something similar to what
you're asking before.
If you're on a Linux system, try this:
awk '!x[$0]++' inputfile > outputfile
This seems to be the best way to remove duplicate lines and still
preserve the original order of the unique lines.

Really nice solution indeed :D I didn't know array_unique() (well, that's
not entirely true, I had read about it once or twice, but didn't remembered
it).
Anyway, I remembered after I sended the mail that the order DO matter, but
that is just reversing an array :)
Just for the record, the applied code is:
$string =
implode('}',array_reverse(array_unique(array_reverse(explode('}',$string)))));
First, an explode of the string to create an array, than I reverse it so
that the last ocurrence of the repeated part will always be last, after that
I apply array_unique, de-reverse it and implode it all back together as a
string.
Result?
input:
hi{value1;value2}bye{value1;value3}hi{value1;value4}hi{value1;value2}bye{value1;value2}
output:
bye{value1;value3}hi{value1;value4}hi{value1;value2}bye{value1;value2}
Thank you very much !
@Ashley: It must be done in PHP, because it should run in any environment.
But thanks anyway, any help is apreciated: you just saw that there was a
much easier way than trying to use regular expressions or str_replace when
using arrays is considerably faster (especially because the $string won't be
a few bytes, it could range from ~5 bytes up to ~300+ KiB).
Greetings!

No, I do NOT want to use nl2br.
For one thing, nl2br isn't xml safe so I'd have to do another
preg_replace to fix that. My bbcode parser is xml safe.
For another thing, my bbcode parser doesn't like html in its input, and
this needs to be done before the parser.
'/\n/','[br]'
works exactly as I want it to right now except I do not want it replace
the newlines inside [code][/code] as that messes up the syntax
highlighting that is then done one the code block.

I got it, though it may not be the most elegant way.
I split the input up into array and do the preg_replace on array
elements that are not inside [code]. Seems to work, and also solves the
other problem (other problem being proper application of strip_tags
except inside [code].

I think generally though, it's usual to have the pages created and
output on the fly, rather than output the .html page. Some CMS's do
publish the .html pages, but unless the page is created from very
complex content, or your site is expecting a large amount of traffic,
there's not much use to do it. I've heard people mention SEO as a
reason, but I've not seen any evidence, and there are ways via
mod_rewrite to mask the actual content pages.

Yes, though often using a cache if it is dynamic content that doesn't
change often. No reason to hit the db continuously if the content is the
same as when you hit it the last 278 times.

sounds to me like the objects are a stored in a variable, each time
the same variable that the var in question is assigned by reference
(this is done in php4 code quite a bit so that objects that are
passed around are not copied - which makes them useless in many instances)
the following code mkight help you to understand what it is (that I think)
is happening:
// php4 compatible class
class Foo { var $s; function Foo($s) { $this->s = $s; } };
$store = array();
$var = new Foo("A");
$store["A"] =& $var;
$var = new Foo("B");
$store["B"] =& $var;
$var = new Foo("C");
$store["C"] =& $var;
var_dump($store);

Exists any reports generator that exports directly to html/php?

Hey all,
I have an SQL query that's stumping me.
I have two date variables, $start and $end that are in mm/dd/yyyy
format and two database fields, start_date and no_donations. The
start date is mm/dd/yyyy format and no_donations is an integer that
represents the number of months from start_date that donations will
be made.
So if start date is say 02/01/2010 and no_dations is 4 then
donations will be made four times from the start date for four
months.
What I need to do is come up with a query that will determine if the
start_date + no_donations falls within $start and $end.
But I'm pretty stumped. How can I convert start_date + no_donations
in the database to the date when the last donation will take place
so I'll now if the donations fall between $start and $end?
Any suggestions would be very help and appreciated,
Skip

Skip:
Here's a snip-it of code from one of my projects:
$qry = "SELECT SUM(amount) AS subtotal, COUNT(*) AS num
FROM transaction
WHERE product_type = 'video'
AND UNIX_TIMESTAMP(transtime) > " . strtotime($startd) . "
AND UNIX_TIMESTAMP(transtime) < " . strtotime($endd) . "
AND is_charged = 1
AND notes = 'Approved'
AND is_refunded = 0
AND transnum NOT LIKE 'TEST-PNREF'
AND product_id LIKE '$key' ";
$db2->select($qry);
while ($db2->readrow())
{
$rev = $db2->data["subtotal"]; // this is the total amount
collected for the sale
$num = $db2->data["num"]; // this is the number
of this type of sale
}
Clearly, you don't need everything there, but the timestamp notation
will give you better insight into how to use dates in your query.

I use seconds from epoch in the database simply because it works so well
with the php date() function.
If you need something where Julian day really is better, I assume it
isn't that hard to convert between posix and julian day, though it seems
odd to me that it isn't part of the date() function. It probably should be.
When I do date comparisons in MySQL I use the to_days() function.
> What I need to do is come up with a query that will determine if the

In the given example one could determine that a month is always 30 days
and then say to_days(start_date)+(no_donations*30) < to_days(end). This
would however be a very loose method. You could go for finding the
number of days in the current month and substract that (10th. = 30-10),
play with MySQLs left() function
But Skip, as the others say, use a date class, since you're passing a
php var on to the SQL anyway, then you could determine the exact days
from start to end of donation. Combine this with to_days and you have
your solution

I've looked through the docs but was unable to find out if this is possible;
I hope it is. Is there a way that you get the size/length of the collection
to be iterated (e.g. the total number of files) without having to iterate
through at least once?
thnx,

Well if the Iterator has the whole of the collection in order to be able to
iterate over it, I would think that it should be able to return the size of
that collection... :(
