Hi all,
When I do this:
$associacao_dao->listar($limit, $offset);
I can var_dump the correct $limit.
I can var_dump the correct $offset.
I CAN'T access the object that I was hoping to get, called $records.
After this, I was hoping to do var_dump($records); and see the stdClass
object.
Here is the listar method:
public function listar($limit=null, $offset=null)
{
$query_str="SELECT * FROM associacao";
$stmt = $this->_dbh->prepare($query_str . ' LIMIT ?, ?');
$stmt->bindParam(1, $limit, PDO::PARAM_INT);
$stmt->bindParam(2, $offset, PDO::PARAM_INT);
$stmt->execute();
$records = $stmt->fetchAll(PDO::FETCH_OBJ);
return $records;
}
Any help will be greatly appreciated.
Thanks a lot in advance,
Márcio

Solved. Forget to assigning the return value of the method to anything. :S
Sorry.

Then make it a requirement when you are choosing a (shared) hosting
provider.

Have you checked to see if you hosting environment allows custom php.ini files?
If so, then ask them for information that governs their setup on your server.

Meh, there is that! Find a host that has requirements you are looking for.
Which reminds me... I do allow this in my hosting packages.

Actually, I don't think that regexp's are very slow :)
But I haven't tested them from that perspective.
You should just benchamrk different approaches :)
btw, not sure that substr will help you a lot:
first you have to get a begining of the time, block, then you have to find
next X chars.
Btw, you can also do it with a quite simple regexp:
preg_match_all('#\[(.{20})#', ..
(where 20 is amount of characters you want to extract.)
or:
preg_match_all('#\[(.{8})(.{12})#', ..
(where 8 is first part of date, and 12 is second part of date.)
But then you will have to parse this string, to convert it to time, which
could take time.
You should just benchmark different approaches, and check which is fastest.
PS: numbers 20,8, 12 are random, just put whtever you need :)
PPS: haven't tested regexps, just check the idea)
I was trying to stay away from regex as much as possible due to the
overhead? I might be wrong here.
This script will be parsing a lot of requests/sec. Thousands, maybe
more, which it also needs to toss into a DB. I want to try and keep it
as fast as possible. This is tricky when you don't know what you are
doing :). My coding is limited to hammering away at the search box on
php.net until I get a push in the right direction. It's just a hack
from there.
Using phpster's substr suggestion has already sped this up considerably.

Whats the cleanest (I have a really ugly) way to break this:

...
Why not just use regexp ?
For example:
$string = "long text.. multiply lines...
[21/Jul/2009:00:00:47 -0300]
[ 1/Jul/2009:00:00:47 -0300]
[22/Jul/2009:00:00:47 -0300]";
preg_match_all('#\[([ 0-9a-zA-Z/]+):([0-9:]+)
[^]]+\]#',$string,$matches,PREG_SET_ORDER);
print_r($matches);
Output:
Array
(
[0] => Array
(
[0] => [21/Jul/2009:00:00:47 -0300]
[1] => 21/Jul/2009

'Twas brillig, and Miller, Terion at 31/07/09 17:11 did gyre and gimble:
If (ctype_digit($row['critical'])){ echo(" Critical violations found: ".
$row['critical'] .". ");
Remember that empty() does clever stuff for you.
empty('') == true
empty(0) == true
empty('0') == true
empty(1) == false
empty(2) == false
empty('foo') == false
I suspect you were just being bitten by a misconception of what empty()
was supposed to do when you passed certain values to it.
isset() and empty() are subtly different.

Is anyone here interested in discussing programming strategy, or or know of a
discussion
group which is interested in the subject?
The sorts of questions I am interested in are:
1. I have a highly variable program which always shows the same page, but which
includes
different modules to give different results. The various modules call on
different
functions. Is it better to minimise memory by including only the functions
actually
required, but increase the number of files included, or to bundle all the
functions into
one file, thereby reducing the number of files included but increasing the size
in memory?
2. As PHP is an interpreted program comments certainly increase the memory
requirements,
and presumably they slow down the operation of the program. Would stripping out
the
comments before uploading the production version give any visible improvement in
performance?

That depends greatly on your usage patterns. Does your application make lots
of "sideways" calls to integrate different modules, or is just "switch on a GET
parameter, run this function, done"? If the latter, then lazy-loading just
the one or two files you want is probably better. If the former, you'd need a
lot of interesting logic to make lazy-loading work well enough to be justified.
(I've been working on such a system for Drupal for the past year, and it's not
easy to get right because there can be a fair bit of overhead.)
If your application is heavily OOP then PHP supports dynamic autoloading of
classes, which can greatly simplify your code logic but at the same time the
autoload mechanism itself is not free either.
The age of the computer matters, too. Modern hard drives are faster than they
used to be, and more recent OS versions can do some fairly aggressive caching
if the files you're reading all fit inside the OS cache somewhere in memory so
you may not actually hit disk to "load" each of your files.

I actually benchmarked that once. I had a reasonably large PHP file that was,
in fact, over 50% docblocks. That's not even counting inline comments. While
trying to find things to optimize, removing about 800 lines worth of comments
(all of the docblocks) did, in fact, produce a noticeable performance
difference. It was only barely noticeable, but it just barely registered as
more than random sampling jitter. I actually concluded that if cutting the
file *in half* was only just barely noticeable, then it really wasn't worth the
effort.
Just install an opcode cache. That will take care of most of your memory
issues. :-)
