Re: [PHP] My truth comes out [1]
settype looks like a no-go for this; per the php docs... http://php.net/manual/en/function.settype.php -- $bar = true; // boolean settype($bar, string); // $bar is now 1 (string) -- I think using a conditional here is the best (only?) way. $bool = (strtolower($string)=='true')? true: false; and if the default should be true... $bool = (strtolower($string)=='false')? false: true; If you you're going to use it a lot then wrap it in a function. Also, (as was stated) preg_ is overkill here. php has a lot of nifty string functions that should be taken advantage of before jumping onto regex. Chris.

Re: [PHP] Execute a php page and don't wait for it to finish
What about simply having the script trip a flag that another background script checks every 60 seconds or so? Once a minutes a background script checks to see if it needs to preform any tasks. When a user hits a certain page it does an ajax request to trip this flag and immediately returns. The next time the background script checks if it needs to do anything, it sees the tripped flag and preforms the relevant database copy - or whatever :-) Chris.

Re: [PHP] require_once
I see! Yes using an autoloader typically requires following a naming convention for your classes (though you can get around it by defining your own naming rules). I didn't care for it much at first, but it's nice that class names are explicit (less confusion when you have several) and not worrying about requiring all your files is a plus. Chris.

Re: [PHP] simple class constructor
Can you paste the index page's code here? If the page is going blank
there's probably an error (syntax, bad file path, etc). If you have access
you can turn error reporting on so you can actually see the error - or
better yet check the php error log file. Settings for both of these are in
the php.ini file, though sometimes they can be overridden by apache
directives (depending on the setup).

Re: [PHP] Buffering output to allow headers late in code?
I'm working through my class on PHP and I tried to put information from my sign-on process in the navbar. This didn't work well, since I had to reload the page to see it as the navbar was constructed earlier in the code than the signon process. (Hard to explain, as we are building a dynamic web page with lots of include files to fill in the main contnt portion of the page.) I don't know if this will be much help, but I try to do all the controller / model work before I mess with the view side. So the controller starts off with the ball, then he and the model pass it between each other a few times until the controller finally hands it over to the view, who does her magic and makes the score! ... Perhaps that analogy went to far. At any rate! Ideally the sign-on task would be done before any tasks that would use sign-on data. Additionally, the layout of your page should not necessarily dictate the order of any tasks (i.e. the sign-on box being below the welcome box should not mean that the sign-on task gets done before the welcome task). Hope that helps! Chris.

Re: [PHP] Re: Buffering output to allow headers late in code?
Then someone said that using buffering was a bad idea and I should disable it. I think it leads to poor habits like calling controller methods out of the view (essentially what you are wanting to use it for). Using it like that is asking for spaghetti code that's hard to maintain, scale, and train new developers on. I'd imagine it also adds overhead, though I don't know how much - my guess is negligible. OB can be a great tool, but it shouldn't be a hack to get around sloppy architecture. Just my 2 cents :) Chris.
Re: [PHP] class object vs array for db table model
On Tue, Oct 12, 2010 at 2:38 AM, Tommy Pham tommy...@gmail.com wrote:
Hi everyone,
It's been a couple years since I've did a project in PHP. The current
project I'm working on is for PHP 5.3 and I noticed a performance issue.
Is
it just me or is there a BIG difference in performance between class object
vs array for PHP 5.3? Below is the sample:
class MyTable
{
private $_id; // int
private $_name; // varchar
private $_description; // text
public function __construct() {}
public function getId()
{
return $this-_id;
}
public function getName()
{
return $this-_name;
}
public function getDescription()
{
return $this-_description;
}
public function setId($id)
{
$this-_id = $id;
}
public function setName($name)
{
$this-_name = $name;
}
public function setDescription($description)
{
$this-_description = $description;
}
}
$my_table = array ('id' = 'id value', 'name' = 'name value',
'description'
= 'long description text');
The above are representations for my table as class and as array,
respectively. The only difference is how I represent the results from db:
1) as class object
$list = array();
while ($row = $db-fetch($result))
{
$my_table = new MyTable();
$my_table-setId($row['id']);
$my_table-setName($row['name']);
$my_table-setDescription($row['description']);
$list[$my_table-getId()] = $my_table;
}
2) as table
$list = array();
while ($row = $db-fetch($result))
{
$my_table['id'] = $row['id'];
$my_table['name'] = $row['name'];
$my_table['description'] = $row['description'];
$list[$my_table['id'] = $my_table;
}
The performance difference I get is about 1.4 seconds with the array in the
lead!!! Does anyone have the same problem?
Thanks,
Tommy
PS: The above executed in 4.2 sec and 1.8 sec (on average) respectively w/o
actually showing the results to html, while my ASP.NET project executes it
and displays in html in about 2 seconds for all 3684 rows, using class
similar to the MyTable. All codes, PHP ASP.NET C#, access the same
MySQL
DB on the same development box.
When you are adding a row as an object you are calling 4 user
functions: MyTable::__construct(), MyTable::setId(),
MyTable::setName(),
and MyTable::setDescription(). This adds some overhead for sure, so you
might want to think about passing the row array into the construct and doing
away with the setters (at least for the initial instantiations).
Something like this...
-
public function __construct($dataArray=null)
{
foreach ((array)$dataArray as $rowKey = $rowValue)
{
$this-$rowKey = $rowValue;
}
}
==OR==
public function __construct($dataArray=null)
{
// maybe add casting here as well?
$this-_id = isset($dataArray['id'])?
$dataArray['id']: null;
$this-_name = isset($dataArray['name'])?
$dataArray['name']: null;
$this-_description = isset($dataArray['description'])?
$dataArray['description']: null;
}
==And instantiate like this==
$list = array();
while ($row = $db-fetch($result))
{
// I also changed setting the $list's key with $row['id'] instead of
using the MyTable getter.
$list[$row['id']] = new MyTable($row);
}
---
I don't know how much faster that will run for you (if at all) but using
your method you were calling 5 user functions per result set from the db
(that's the construct, the getter to set the $list key, and 1 for each of
the 3 properties of the result) for a total of 18,420 user function calls.
With my method I'm calling 1 user function (the construct) for each set,
for a total of 3,684 calls. Of course a down-side is that if there's any
logic in your setters then that needs to be replicated in your construct.
Another method is to use a single object for all 3684 records. Perhaps you
can use the built in Iterator interface which lets your class's objects be
used as if they were an array for the purposes of foreach loops.
http://php.net/manual/en/language.oop5.iterations.php
You would set a pointer to the record you wish to use, and your getters and
setters would key off that element of the master array. This should be a
fast solution, while still giving you the power of encapsulation, getters
and setters.
Hope that helps!
Chris.

Hi Chris,
Thanks for the reply. The sample I made is just for simplicity and
comparison. As for function calling 'get's, I think the speed would
come out to be same in your sample since you're doing isset()
checking. My actual class is more sophisticated having the psuedo
overloading as you mentioned. The class is generated from a PHP class
builder - to save on typing - I made a long time ago with some minor
update.
Anyway, I was frustrated as to why my code took so long to execute and
had to dig deep. As it turns out, I had xdebug loaded with all
options on ... lol. Removed the extension and all is good in the
world. The script runs in less than 150ms :D!!!
Thanks,
Tommy

...

foreach ($_SESSION['life_coaching_order'] AS $coaching_fee_theme_reference

In this example $value would be an array. To test if it is a gift or not you
would do this from within the foreach loop:
//gift
if ( isset($value[1]) isset($value[1]['quantity']) )
{
$gift_quantity = $value[1]['quantity'];
}
//personal use
if ( isset($value[2]) isset($value[2]['quantity']) )
{
$personal_quantity = $value[2]['quantity'];
}
Technically the above IF's are optional, but they are proper syntax.
I don't know how you are with OOP, but you may have more luck using objects
instead of a complex array.

It doesn't have to use the braces. The braces only tell PHP exactly
where to stop parsing the current variable name. The following examples
wouldn't work without them:
$var = 'hello ';
$arr = array('msg 1'='hello','msg 2'='world');
echo {$var}world;
echo {$arr['msg 1']}{$arr['msg 2']};
Without the braces, in the first example PHP would look for a variable
called $varworld, and in the second it would be looking for a simple
scaler called $arr, not the array value you wanted.

Just to add in here, they are also required when calling an object's
properties, if - ready for this? - that object is itself a property of
another object.
so while this would work,
$circle-circumference
this would NOT work
$circle-circumference-inches
The later would be injecting the $circle-circumference property, followed
by string literal -inches. So to get it to work you would need to use
curlys.
{$circle-circumference-inches}

I would say yes to the way you are asking. Take the following two

script.
Application A:
?php
class foo {}
$db = new foo();
$outA = barA();
function barA() { global $db; include(Application B); }

Application B:

class bar {}
$db = new bar();
$outB = barB();
function barB() { global $db; }

The bridge project is operating in A and include()'ing the script that is B
(as I have not found an API for B). $db in B is colliding with $db in A.

[PHP] PHPExcel with large files (27,000+ rows)
I'm currently working on a project that requires the parsing of excel files. Basically the user uploads an excel file, and then a script needs to save a row in a Postgres database for each row in the excel file. The issue we are having is that when we task PHPExcel with parsing an excel file with, say 27k rows, it explodes with a memory error. I've read up on the PHPExcel forums and we've tried cell caching as well as ReadDataOnly, they do not seem to be sufficient. Does anyone here know of a way to do this? Surely there is a way to parse a large excel file with PHP. This is also NOT an on-demand service. That is, when someone uploads a file they get a task_id which allows them to check the status of their excel file. So the solution does not need to be a fast one! Thanks, Chris.

$insertSQL = sprintf(INSERT INTO family (firstname, lastname, email,

Re: [PHP] Little Parsing help...
Don,
How far along are you? To get started something like this may work for
you...
preg_match_all('/[A-G]{1}#?/', $line, $matches);
That SHOULD return each note of the line (you can retrieve them via the
$matches array), given that there are no other upper-case characters that
are not notes. Also this assumes that $line has exactly one line in it. :)
If you get that working, perhaps you can setup something using the
preg_replace method?
http://php.net/manual/en/function.preg-replace.php
Another option is to use the str_replace function.
http://us3.php.net/manual/en/function.str-replace.php
I gotta run (else I would type some more) but let me know if you want any
advice on using those!

The logic I need is pretty straight forward, but I am having a hard time
replicating it using PHP functions. I will try to break it down to it's

I have a field that has several lines of text. Chords and Song Lyrics.
The Chord lines begin with an asterisk * and end with the line break.
This is the string I want to parse. Lines with no asterisk at the beginning
are ignored.
Based on 3 arrays of NOTES, I want SUBSTITUTE the text (based on exact text
character patterns - just NOTES not the chord type) of the lines in my field
that start with an asterisk *.
original_chord_array = A, A#, B, C, C#, D, D#, E, F, F#, G, G#
transpose_up_array = A#, B, C, C#, D, D#, E, F, F#, G, G#, A
transpose_down_array = G#, A, A#, B, C, C#, D, D#, E, F, F#, G
It is important that it only effects EXACT strings. Notes will always be
capitalized and chord types will be lower case. Maybe we can use that
characteristic to better identify what to change. Here are some examples of
chords:
A
Asus7
Csus add9
Dmaj7
F#m7
G#
C#dim no3
When I transpose UP these chords, just the NOTE should change:
A#
A#sus7
C#sus add9
D#maj7
Gm7
A
Ddim no3
When I transpose DOWN these chords, just the NOTE should change:
G#
G#sus7
Bsus add9
C#maj7
Fm7
G
Cdim no3
I am working on a function, but still not producing the proper results.
Hopefully this break down is more clear and someone will bail me out ;-)
Thanks again for the feedback.

is exactly this same as doing this...

$normal = array();

Re: [PHP] Copying an Object
You could create a method of class B that takes an object of class A as a
parameter and copies each property line by line (or method of class A that
takes an object of class B...). If you don't want to add a method you could
just do the same thing, but procedurally. The issue with this (aside from
being bad oop) is that you can't copy private properties unless you have all
the required getters and setters. The issue with both of these is that it's
ugly, high maintenance code.
There is the iterator class, extending from which would allow you iterate
through all of your properties in a foreach, but if you don't want to add a
new method then you likely don't want to add a parent class.
I don't care for any of these options, but as far as I know there's no
internal PHP mechanism to to copy all the properties from one object to
another object of a different class - please correct me if I'm wrong. Is it
possible that there's a more elegant solution to your problem that does not
include a mass copy of all an object's properties? (e.g. using statics like
Mr Bungle suggested or perhaps some nifty design pattern?)

My thought is to adjust the session expiration in the table based on the client currently logged in. I don't know if there's a better way, but I would probably just do that. The expiration would be set to whatever the client's preference is, and default to 8 hours if he doesn't have one.

No access whatsoever! Normally, I would just set up a field in the database and have that set to yes or no as to if the employees could access the database, or not. But in this case, the boss does not want even that type of access to the database permitted. Repeat -- No access whatsoever! I was thinking of the boss' script writing to a file that accomplished the yes or no thing, but if the boss did not log off properly then the file would remain in the yes state allowing employees undesired access. That would not be acceptable. So, what methods would you suggest? Cheers, tedd You sure know how to pick'em Tedd. This is the second whacky client you've posted about on the list...

I don't have a complete solution for you as I just don't care enough about helping this Dbag lord over his employees like that, but I suspect you could have /etc/init.d/mysql start or stop at some pre-determined times like 8am - noon. Then noon till 5pm. Or something. RDBMS are not really designed to be turned on and off like that. Another option is to maybe use M$ Access instead (which does have a multi-user mode). Use ODBC to connect via PHP to it. So then he would start up the DB when he likes and shut it down when he likes. (note that a logout of Windows will NOT prevent the ODBC connection as it is a service -- as God intended RDBMS to be) http://www.configure-all.com/php_access.php This guy is making me angry just thinking about it! d Yes I've been following this post purely in the hope that someone gets Tedd is explain the client's logic on this one.

Great idea! And when he makes a suggestion we can totally ignore him! SQL - Shmeequal Rant aside; I would defer the logistics to the client. He wants the DB to shutdown when he's not in the office? Ok no problem - not what it was designed to do, but no problem! How would you like the system to be aware of rather or not you're in the office? It can assume you are between these hours; You can log into a screen that unlocked it, but then you have to logout; we can put a motion detector in your office; ... etc. This would put the consequences of the system off on the client.

[PHP] Zend framework
Hello all, I'm starting a new project and I'm thinking about building it on Zend framework and possibly Zend server. I've only used the framework slightly and I've never really used Zend server. That being said I hear that the framework is pretty decent to work with. I want something that is strict and uses OOP MVC well, and I hear it does; though I also have the impression that it's slow and bloated... Anyways, I was curious if any of you have some general advice / good things / horror stories on the Zend framework? Thanks, Chris.
Re: [PHP] Reformat array result.
Paul,
How are you matching the records in the event count array to the ones in
the timestamp array?
Is it safe to say that:
$timestamp[ $i ] corresponds to $eventCount[ $i ]?
If so, you could just iterate through the timestamp array; on each iteration
create a record in a new array that holds the timestamp and whatever the
corresponding eventCount record is. Something like:
$newTimeArray = array();
foreach ($timestamps as $i = $singleTimestamp) {
$newTimeArray[ $i ] = array(
'timestamp' = $singleTimestamp,
'count' = $eventCounts[ $i ]
);
}
Now if $timestamp[ $i ] does NOT correspond to $eventCount[ $i ] then I
think we'll need you to explain how that relationship works, unless I missed
something :)

Lets say that coming into this, I knew that the query spanned 36 hours
and started at 01:00. How can I manipulate the resulting array to
contain the missing time stamps and a value of 0.
The effect I am shooting for looks like this:
http://www.pintumbler.org/example.png
So 0 - 23 will be static and I just walk through the array and
populate those. If we hit 23, start a new row and continue. The matrix
will always be the same though.
I think I know what needs to happen, I just cant come up with the logic.
Any push in the right direction would be appreciated.

Hi list,
I know that some languages such as C++ can overload functions and

arguments, and the compiler internally sorts things out, but I can't
seem to find a similar way to do this with PHP.
Basically, what I've got at the moment is a class method with 2
arguments, and I need to be able to overload the method with 3
arguments. The following which would work in other languages doesn't
seem to bring any joy in PHP:
class foo
{
public function bar($arg1, $arg2)
{
// do something with $arg1 $arg2
}
public function bar($arg1, $arg2, $arg3)
{
// do something different with all 3 args
}
}
Is there any feasible way of doing this? The method names really need to
remain the same as they exist as part of a framework, but the arguments
really server quite different purposes between the two methods, so
there's no nice way of just merging the two functions without breaking
the naming conventions, etc used.

Re: [PHP] It's Friday (a MySQL Question)
Well you certainly can not use this without the command line, however some
hosts restrict you from the command line but still allow you to run commands
via php's exec() function (Rackspace Sites is an example of this).
pseudo code example:
exec('mysqldump [options] --all-databases ... ');
Of course this is only if your hoster supports it, and if the user has
proper mysql privileges (which I think are SELECT, LOCK TABLES, and SHOW
VIEW).
mysqldump is a great program with many options so you can dump your db just
the way you want it ;) If it's something you can and choose to use I would
suggest reading over the link I sent you so you can customize it's output.

Re: [PHP] Setting up a 2 Column Display for SQL Recordset
Dave I would look into something like the array_slice function.
http://us3.php.net/manual/en/function.array-slice.php
With this function you could create two arrays - one for the left column,
and one for the right column - and iterate through them simultaneously.
i.e. untested: given $allNames is an array with all 200 names
--
$firstNameSet = array_slice($allNames, 0, 100);
$secondNameSet = array_slice($allNames, 100);
foreach ($firstNameSet as $key = $nameA) {
$nameB = $secondNameSet[$key];
...
...
}
-
Alternatively you can use a nested query to pull the results in two sets
directly from the sql db.
Hope that helps
