[PHP] Recommendation request: Use Magento or build my own eCommerce?
Hi, I'm in a difficult situation here. I have a list of requirements for an eCommerce system (Magento) where i'm getting mixed opinions about what to do. Note: i do consider myself to be a quite experienced PHP programmer and certainly have the skills to either make the extensions or make everything from scratch. Both do require month of work! First - for the complete picture - the list of requirements for the eCommerce system: - (buld into magento) Multishop has to be possible - Different payment modules have to be possible (buckaroo, afterpay, ...) - Online chat (with for example zopim) has to be possible - Advanced product permissions (magento only has manage not more specific as in edit) - Setting pruduct margins - Abandoned cart alerts - One page checkout - Some javascript/ajax things like instant cart - A very specific order page (the Booking and Reservations plugin can do that) Thus far it's all oke. However, if i go to the magento irc channel i'm getting really mixed opinions about what to use and what to create myself. They basically say that i should prevent installing as much extensions as possible and try to make most of the things myself. This is where i'm getting really confused. There are two possible routes to take here. 1. I can go for the magento route and just take the very steep learning curve it has. It will be a slow process to make the modules required (mainly the advanced permissions, setting product margins and a abandoned cart extension). Two of those three are very difficult to make. Certainly if you consider that i'm just starting developing in any eCommerce system. 2. Considering the steep learning curve of making extensions for Magento it might be easier - in the long run - to build it all myself. In the beginning that will be an even slower process then using Magento, but once the structure is build it will be a much faster development process for any extension. I know it's usually a bad thing to reinvent the wheel and i am certainly not intending that. However, right now i really get the impression that i'm better of making it all myself. Both approaches take many months of development where the self made version is going to pay off in development time in the long run when compared to magento. I am just not sure what the best solution might be. So here is a list of pros and cons that i can think of for both approaches. Pros/Cons for using magento - [pro] a lot of existing extensions - [pro] i don't need to worry about security updates since the come from magento - [pro] living community around it to help out if there are any issues - [con] very steep learning curve - [con] not straightforward to start developing in - [con] takes a lot of time till you can even use the basics Pros/Cons for self made - [pro] Development will go a lot faster - [pro] i can make it more specific for one goal - [pro] a much easier extension model - [con] security all depends on me - [con] i have to make complicated extensions like buckaroo and afterpay myself - [con] no existing library of extensions to use Again, i'm puzzled by this. If i follow the #magento (on freenode) list then i should pick magento, but make every extension myself or only use the really good ones. Thus that will require a lot of time to develop them. I 'm guessing about half a year. Then again, if i make it all from the ground up it's probably also going to take half a year to develop (or slightly more) but it will obviously be much easier to maintain since i know every single line of it. What is your recommendation? Build it myself? Use Magento? or another option that i didn't even consider yet? Kind regards, Mark

The PluginLoader is loading the plugins.
The PluginInterface defines an interface which each plugin has to implement.
PluginOne and PluginTwo are plugins that implement the interface.
Each plugin (PluginOne and PluginTwo) are stored in their own folders.
So the folder structure would be somewhat like this:
|- Plugins
|- - PluginOne
|- - - PluginOne.php
|- - - other possible files
|- - PluginTwo
|- - - PluginTwo.php
|- - - other possible files
|- PluginLoader.php
|- PluginInterface.php
Now making this structure isn't an issue. I can do all of that just
fine. The place where i'm actually going to make a plugin instance is
where things get a little more complicated. The PluginLoader simply
reads all the dirs in the Plugins folder and tries to find a filename
with the same dir. So if it reads the dir Plugins/PluginOne it will
try to include the PHP file: Plugins/PluginOne/PluginOne.php. That's
fine and working.
To actually make a plugin instance i can do two things that i know of:
1. use eval like so: eval('$obj = new '.$pluginName.'();'); and
register it to the PluginLoader.
No need to use eval, you can simply do this:
$obj = new $pluginName();
See here: http://php.net/language.variables.variable
Ahh right, i completely forgot about that option. That might just work
the way i want it :)
2. Let the plugin itself (so in this case PluginOne.php) open itself
and register it to the PluginLoader.
With the first option i have to do eval which i try to avoid if possible.
With the second solution the PluginLoader probably has to be a singlethon.
Why does it need to be a singleton?
Well, i would then do something like this from within the included
plugin file after the class:
PluginLoader::getInstance()-registerPlugin(new PluginOne());
Or something alike.
Now my question is: what is the right way of loading plugins like
this? Is there some other option then the two i described above? My
PHP limitations are the newest version so no limitation there :)
I'm kinda leaning towards the second option now since that seems to be
quite stable and not very error prone. The eval one is much easier to
break :p
If you're happy for each plugin to be in a separate directory then what you
have in option 1, minus the eval, will work perfectly well. I don't know what
your use case is but if there's a chance a single plugin might want to
provide several classes then I'd require an init.php in each plugin folder
and have that register the class names with the class loader. It could also
then pass along some meta information such as a description of what each
class does. If this is for use in web requests you might want to stick to
what you currently have as there's a lot less overhead.
Yeah, if i extend it more that will certainly be an requirement.

Well, i'm making the classes up as i type. I don't actually have a
PluginLoader yet. Or rather, i'm just beginning to make it right now.
What it's doing is very simple. Read through the directory of the
plugins and load every single plugin it finds in memory. Then every
plugin registers the mime types it can handle. That information is
stored in the PluginLoader upon which some other place can call:
PluginLoader::pluginForMime(text/html). Though i still have to take
a good look at that.

Ahh, I see. Personally I'd go with the following (pseudocode)...
Inside the PluginLoader constructor (or other method)
foreach (plugindir)
require plugindir/plugindir.php
$plugindir::init($this)
The static init() method calls PluginLoader::registerPlugin('mime/type',
'PluginClassName'). Then pluginForMime does a lookup for the mime type and
returns an object of the corresponding type. That way a single plugin can
support multiple mime types.

[PHP] What's the best way to make a dynamic plugin architecture?
Hi,
Envision the following plugin architecture:
class PluginLoader
{
}
interface PluginInterface
{
.. some function definitions ..
}
class PluginOne implements PluginInterface
{
}
class PluginTwo implements PluginInterface
{
}
The PluginLoader is loading the plugins.
The PluginInterface defines an interface which each plugin has to implement.
PluginOne and PluginTwo are plugins that implement the interface.
Each plugin (PluginOne and PluginTwo) are stored in their own folders.
So the folder structure would be somewhat like this:
|- Plugins
|- - PluginOne
|- - - PluginOne.php
|- - - other possible files
|- - PluginTwo
|- - - PluginTwo.php
|- - - other possible files
|- PluginLoader.php
|- PluginInterface.php
Now making this structure isn't an issue. I can do all of that just
fine. The place where i'm actually going to make a plugin instance is
where things get a little more complicated. The PluginLoader simply
reads all the dirs in the Plugins folder and tries to find a filename
with the same dir. So if it reads the dir Plugins/PluginOne it will
try to include the PHP file: Plugins/PluginOne/PluginOne.php. That's
fine and working.
To actually make a plugin instance i can do two things that i know of:
1. use eval like so: eval('$obj = new '.$pluginName.'();'); and
register it to the PluginLoader.
2. Let the plugin itself (so in this case PluginOne.php) open itself
and register it to the PluginLoader.
With the first option i have to do eval which i try to avoid if possible.
With the second solution the PluginLoader probably has to be a singlethon.
Now my question is: what is the right way of loading plugins like
this? Is there some other option then the two i described above? My
PHP limitations are the newest version so no limitation there :)
I'm kinda leaning towards the second option now since that seems to be
quite stable and not very error prone. The eval one is much easier to
break :p

Thanks. Jeff In addition to Ashley's response, server variables can be populated with different values on PHP/Apache/Linux versus PHP/IIS/Windows. This can be a particular issue if you're writing 404 handlers or anything that relies on query strings. In particular you need to test and check for differences between Apache and IIS in how the REQUEST_URI, QUERY_STRING, URL, and ORIG_PATH_INFO variables are populated depending on whether your script is being called directly or as a 404 handler. When redirecting due to a 404 or some other redirect or error IIS will populate some variables with values like this /404.php?404;http://www.server.com:80/blah.php?v=1t=2; whereas Apache will populate the same variable with /blah.php?v=1t=2 in the same situation. This means the query string needs to be parsed differently. You need to test for your own usage scenarios. -- MarkR PGP public key: http://www.signal100.com/markr/pgp Key ID: C9C5C162 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Just to clarify on this point, Windows (or rather NTFS) permissions use full ACLs and so, for each file system object, any number of users and/or groups can have any number of allow or deny permissions assigned to them for a range of activities (e.g. read, write, append, delete, create, execute, traverse, read/write attributes, read/write permissions, etc.).

Give it a default (possible empty) value:

Using an empty string and the empty() function in this way can lead to subtle
and hard to find bugs - for example if $z = 0, the code will not be executed.
Note the list of things that are considered empty:
http://uk.php.net/manual/en/function.empty.php
Instead, consider setting the default value for $z to boolean false:
function MyFunction ($x, $y, $z = FALSE) {
if ($z) {
// do stuff with $z
}
}
In this way almost any value in $z will trigger the conditional code,
including 0 or an empty string. The exceptions are FALSE and NULL. If you
explicitly need to react to a NULL value, use is_null() to detect it.

Re: [PHP] Including files on NFS mount slow with APC enabled
Thanks for your answer. I have tested this option before, and it indeed
disables the stat() operation. However, it doesn't disable the open()
operation, which is about 10x slower than the stat() call (see my
example trace).
On 08/16/2010 07:21 PM, Jonathan Tapicer wrote:
Hi,
APC checks by default if every included file was modified doing a stat
call. You can disable it, setting apc.stat to 0
(http://www.php.net/manual/en/apc.configuration.php#ini.apc.stat). Try
if that improves the performance. Of course, you should manually
delete the APC opcode cache every time you modify a PHP file, since
APC won't detect that it was modified.

?
The query should be:
SELECT * FROM `userinfo` WHERE `user` = '$user' AND `pass` = '$pass'
Remember: ` for tables and columns, ' for strings.
Also, look up SQL Injection, as your script contains a huge vulnerability.
This can be fixed using mysql_real_escape_string, so it is this:
ELECT * FROM `userinfo` WHERE `user` =
'.mysql_real_escape_string($user).' AND `pass` =
'.mysql_real_escape_string($pass).'

The query should be:
SELECT * FROM `userinfo` WHERE `user` = '$user' AND `pass` = '$pass'
Remember: ` for tables and columns, ' for strings.
Also, look up SQL Injection, as your script contains a huge vulnerability.
This can be fixed using mysql_real_escape_string, so it is this:
ELECT * FROM `userinfo` WHERE `user` =
'.mysql_real_escape_string($user).' AND `pass` =
'.mysql_real_escape_string($pass).'

[PHP] Checking correct usage of fopen(), stream_set_timeout() and fread() [newbie]
Hi,
I have some code to download large files as part of a larger class. I've
been in a discussion with the developer of a library that I'm using who has
told me clearly that my code will not work at all, even though it does. He
is suggesting my problems are due to my not understanding the nature of
fread() even the code is very similar to examples on php.net.
I do get very rare timeout problems where the stream_set_timeout() does not
seem to be firing, and PHP exits on a general timeout. However I'm using
this under Tomcat and the logs are not giving me as much information as
under Apache webserver, where I have been unable to reproduce this problem.
So it's proving difficult to track down and I'm not able to reproduce the
error consistently. I would appreciate any comments about the validity of
the code (at the bottom) so I have a better idea whether it is my problem,
or not. It might be that I need to catch and handle the error, but that is
an area where I have no experience as yet.
I'm aware the code could be rewritten in CURL, but for now I'm more after an
understanding of what problems there might be, if any, with this approach.
The server is returning content-length in the header, and chunk encoding is
not an approach I'm intending to use right now.
Also, I'd appreciate any ideas on what the developer might mean by the
following quote. He's asked that I do not use his mailing list anymore and
should take my questions to php-general, so it would be impolite to ignore
this so I can ask him to explain further:
3. The network buffer used by the PHP streams implementation reads data
eagerly. If you fread($socket, 1024) and the network buffer already
contains 24 bytes, PHP will try to read 1000 bytes nevertheless.
My understanding is the fread() will wait until is has 1024 bytes (in this
example) and then return that, unless EOF is encountered when the data up to
and including EOF is returned. I'm not sure what he's trying to say.
Many thanks for any advice on this.
Mark...
Code:
(The intentions are: used for downloading very large files while avoiding
memory problems, this is contained in a loop for a list of files, if the
socket is unavailable then the download is not attempted for that file, if
the socket is available but no data is received in a 30 second period, then
that download should be aborted and retried up to 5 times)
$download_attempt = 1;
do {
$fs = fopen('http://' . $host . $file, rb);
if (!$fs) {
$this-writeDebugInfo(FAILED to open stream for , http://;
. $host . $file);
} else {
$fm = fopen ($temp_file_name, w);
stream_set_timeout($fs, 30);
while(!feof($fs)) {
$contents = fread($fs, 4096); // Buffered download
fwrite($fm, $contents);
$info = stream_get_meta_data($fs);
if ($info['timed_out']) {
break;
}
}
fclose($fm);
fclose($fs);
if ($info['timed_out']) {
// Delete temp file if fails
unlink($temp_file_name);
$this-writeDebugInfo(FAILED on attempt .
$download_attempt . - Connection timed out: , $temp_file_name);
$download_attempt++;
if ($download_attempt 5) {
$this-writeDebugInfo(RETRYING: , $temp_file_name);
}
} else {
// Move temp file if succeeds
$media_file_name = str_replace('temp/', 'media/',
$temp_file_name);
rename($temp_file_name, $media_file_name);
$this-newDownload = true;

[PHP] Intermittent etwork connection errors with apache. Restarting apache temporarily fixes the problem. PHP or apache problem?
Hi - At the top of my php scripts, I have code to connect to our ldap server, in order for the scripts to make ldap requests. I don't have any disconnect call in my code. Lately I have noticed that the apache server will get into a state where connection requests will occasionally fail. When I refresh the page, the connection almost always succeeds on the 2nd attempt. If I restart the apache server, the problem totally goes away for a long period of time. So I assume that somewhere, something is causing connections to stay opened when the script ends, rather than automatically closing them. This error occurs with other types of network connections that the script makes (besides ldap), so it's not an ldap issue. How does Apache automatically close connections when the script ends? Is it possible that connections are being left opened? Is there any way to debug the problem, i.e. to see if connections are left opened in some way? I'm running redhat 5, httpd-2.2.3-31.el5_4.2 php-5.1.6-23.2.el5_3 Thanks. - Mark -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

How do I read the [0] value? $Result[0] gives me nothing.
Although I'm not that familiar with SimpleXML, since the value returned

Before:
After:
Before: test

After: testamp;test

Re: [PHP] what to use instead of foreach
Hi Phil.
On Monday 13 April 2009, PJ wrote:
Thanks for the suggestion, Mark. I've already experimented with count;
you're close, but there is still a small glitch and that's in count();
foreach doesn't give a damn about count so you can't use that - it is
reset once inside the foreach loop.
Look again at the code - the count() is not inside the foreach, so it is
not reset, simply stored in $lastIndex for comparison.
If your array is associative then simply use another variable to find the
last value in the array - the code doesn't need to change much.
Try actually running the code below - it does work, as does the previous
version I posted if the array is not associative.
I'd prefer it if in future you didn't tell me that my code didn't work
without actually trying it - I tested that snippet before posting it, as I
did with the following.

?php
// Non-associative array (the code I posted previously).
$a = array('1','2','3');
$lastIndex = count($a) - 1;

foreach ($a as $index = $value) {
if ($index != $lastIndex) {
$outputString .= $value, ;
} else {
$outputString = rtrim($outputString,', '); // Strip last comma.
$outputString .= $valuebr /;

echo $outputString;
// Associative array (changed only very slightly).
$a = array('martha' = '1','jock' = '2','dave' = '3');
$lastIndex = count($a);
$counter = 0;
$outputString = '';
foreach ($a as $index = $value) {
$counter++;
if ($counter != $lastIndex) {

Like that? If your array is associative you can drop the $lastIndex calc
and adjust the loop to update a counter instead.

foreach isn't really like that. it uses (IIRC) an internal pointer of

Re: [PHP] SOLVED: Calendar Date Help
Mark Weaver wrote:
Hi all,
I've put this off as long as possible, however I think I've reached an
impasse.
I've got an application that I've been writing. One of the modules for
this app is an event calendar. I've got the calendar to the place where
it displays the current month as well as previous and future months. The
place I'm stuck is it will only show months in the past or the future
that are months in the current year.
Basically the method I'm using to move backward and forward is with Unix
timestamps.
1. When the calendar first loads the what is checked for;
// passed in via $_GET
$what == current, prev, or next
a. current is the default
$now = time()
$prev = date('n',$now)-1
$next = date('n',$now)+1
b. Timestamp values are then stored in an array and then
sent to client in session cookie which is then accessed
upon each subsequent request to display the event calendar.
My question/boggle is why, when the calendar advances to
December(current year) it will display January, but of the current year.
The same happens in reverse.
Once I reach the end of the year either in the past or future the month
increases or decreases accordingly, but the year doesn't change. Since
the year value isn't changing the month calendar days that are displayed
simply repeat themselves.
I know there's something I'm missing, but I am definitely not seeing
what it is...
/** code below /
$cal = new Calendar;
$calpos = array();
// check incoming values
if ($what === current){
$cal-setCal(0,0,0,date('n'),1);

$next = $cal-getStamp(date('n',$now)+1,1);

$calpos['prev'] = $prev;
$calpos['next'] = $next;
$_SESSION['calendar'] = $calpos;

Just in case:
The solution was right in front of my all along. When setting the
calendar object I was giving the class everything it needed except the
{year} value. I _ass_-umed it was being set auto-magically; possibly by
fairies or tree elves. Turns out I needed to set that parameter. Imagine
that... :)

function setCal($h=0,$m=0,$s=0,$offset,$dayVal=1){
$stamp = date('U',mktime($h,$m,$s, $offset,$dayVal,date('Y')));

Solution:
setCal function from Calendar Class:
function setCal($h=0,$m=0,$s=0,$offset,$dayVal=1,$yrVal)
current: $cal-setCal(0,0,0,date('n',time()),1,date('Y',time()));
$prev value coming from session cookie
$now = $session['prev'];
prev: $cal-setCal(0,0,0,date('n',$now),1,date('Y',$now));
$next value coming from session cookie
$now = $session['next'];
next: $cal-setCal(0,0,0,date('n',$now),1,date('Y',$now));
It all works very nicely now.
Thank you Robert for the push to seriously scrutinize my code.

Thank you Robert for the push to seriously scrutinize my code.
It's far more important to learn to build complex code from simple code,
than to try and understand complex code and then refactor it to simple
code. Just a thought for the future since as it stands you have a very
convoluted system of moving back and forth between months.
Cheers,
Rob.
The particular block of code you're referring to definitely needs to be
re factored, however at the moment I don't know enough about php to
accomplish that. I think one of the bad habits I got into early on was
coding verbosely so I wouldn't have to comment as much. That definitely
doesn't serve very well at times.

[PHP] Calendar Date Help
Hi all,
I've put this off as long as possible, however I think I've reached an
impasse.
I've got an application that I've been writing. One of the modules for
this app is an event calendar. I've got the calendar to the place where
it displays the current month as well as previous and future months. The
place I'm stuck is it will only show months in the past or the future
that are months in the current year.
Basically the method I'm using to move backward and forward is with Unix
timestamps.
1. When the calendar first loads the what is checked for;
// passed in via $_GET
$what == current, prev, or next
a. current is the default
$now = time()
$prev = date('n',$now)-1
$next = date('n',$now)+1
b. Timestamp values are then stored in an array and then
sent to client in session cookie which is then accessed
upon each subsequent request to display the event calendar.
My question/boggle is why, when the calendar advances to
December(current year) it will display January, but of the current year.
The same happens in reverse.
Once I reach the end of the year either in the past or future the month
increases or decreases accordingly, but the year doesn't change. Since
the year value isn't changing the month calendar days that are displayed
simply repeat themselves.
I know there's something I'm missing, but I am definitely not seeing
what it is...
/** code below /
$cal = new Calendar;
$calpos = array();
// check incoming values
if ($what === current){
$cal-setCal(0,0,0,date('n'),1);
$now = time();
$prev = $cal-getStamp(date('n',$now)-1,1);
$next = $cal-getStamp(date('n',$now)+1,1);
$calpos['curr'] = $now;
$calpos['prev'] = $prev;
$calpos['next'] = $next;
$_SESSION['calendar'] = $calpos;
}

Hi Rob,
Changing:
function setCal($h=0,$m=0,$s=0,$offset,$dayVal=1){
$stamp = date('U',mktime($h,$m,$s, $offset,$dayVal,date('Y')));
To:
function setCal($h=0,$m=0,$s=0,$offset,$dayVal=1){
if (date('Y') date('Y',date('U',mktime($h,$m,$s,
$offset,$dayVal,date('Y')
{
$stamp = date('U',mktime($h,$m,$s, $offset,$dayVal,date('Y')+1));
}
else
{
$stamp = date('U',mktime($h,$m,$s, $offset,$dayVal,date('Y')));
}
Makes no change. Strange condition still exists. I was rather hoping
that if date('U',mktime($h,$m,$s, $offset,$dayVal,date('Y')))
is smart enough to know to increase or decrease the month value that it
would do the same to the year value accordingly.
$offset contain either date('n',$timestamp)-1 or date('n',$timestamp)+1
The $timestamp value comes from the array being stored in the
$_SESSION['calendar'] as either 'current', 'prev', or 'next'.

the solution, but essentially what I need to do in the getStamp function
is test the {year} of the stamp that results from the incoming $dateStr
against the actual {year} value of the current year's timestamp time().
In case it helps below is the code being used in it's entirety.
The first block of code is the Calendar class and the second is the code
for the page which displays the event calendar.
my appologies if it's all jumbled up.

Well, of course it's sloppy. I've only been coding PHP OOP since
January. :) Given the app is barely in the alpha stage I wanted to start
with a simple premise and wait till development is further along to make
the ugly bits more elegant.
At the moment I don't understand why getStamp() isn't taking $dateStr
and returning the the {year} for date stamps in past or future outside
the current year.
(value being passed to getStamp() inside $dateStr is 'date('Y')-1')
When I can understand what I'm currently doing wrong premise changing
will likely make a lot more sense.

Ok... I've made a change to getStamp() using the two lines above to see
what would happen, however the results are the same. If I move through
the months up to December the calendar moves normally and correctly.
But, once I get to January it displays January for 2008 and never
increments the year.
getStamp() now looks like this:
public function getStamp($stamp,$d){
if ($d === 1){
return strtotime( '+1 month', $stamp );
}
elseif($d === 0){
return strtotime( '-1 month', $stamp );
}
}
I know it's a matter of me not understanding fully what I'm doing; I'm
just not sure where to go from here.

[PHP] Two word array Value
I am trying to use array's to populate a group of check boxes for a form. I

getting part of the array.
Form Page:

Break Out Classroom, Gym = Gym,
Firearms Range = Firearms Range, EVOC Track = EVOC Track);
$cols = 4;

foreach($vars as $key = $value){

echo tdinput name=.$key. type=checkbox
value=.$value./tdtd.$value./td;
$cols++;
}
echo /tr/table;
echo br /;
When I submit the form I am only getting the following having checked the
boxes for Mail Classroom and Break Out Classroom. If I eliminate the spaces
between the words, I get everything, but when I put the spaces between the
words in the array, it cuts off the second word. Not sure what is
happening?

It shows me everything that has been submitted but NOT any of the above

IE7 _not_ in FF (am using 2.0.0.13)
Anybody else face anything like this?
Is this a bug in FF? Is $_REQUEST wrong to catch this?
Dont know what the @#$@ to do... ANY help even a link to a site which can shed a little light would be appreciated.
Thanks in advance.

Hi Ryan,
Since I'm relatively new to PHP I could be off on this, but I'd say yes,
$_REQUEST is wrong. I would think you'd want to use $_POST to receive
the incoming values from a form.

That doesn't make sense. You're selecting a group function (COUNT)
along with other columns which you're not grouping on. It might help
if you told us what you were trying to accomplish with the query.
But you'd be better off asking on a SQL list instead of a PHP one.
FROM sales
LEFT JOIN IGuser ON sales.IGuid = IGuser.IGuid
LEFT JOIN branch ON IGuser.branchID = branch.branchID
LEFT JOIN company ON branch.companyID = '{$companyID}'
WHERE maincompanyid = '{$mcid}'
GROUP BY branch.branchID
ORDER BY branch_name ASC
However, i do not want those join records to be appended, only to return the
count of records from sales.
So why are you joining in the first place?

Do a preg match to find one or preg_match_all to find all the john in the

preg_* is overkill if you're just searching for a literal string. use
it if you're searching for any strings matching a pattern, part of

for, strstr() is both more efficient and easier to use.
Now, strpos() is more efficient still, but arguably more annoying to
use because of the 0 but true issue that necessitates checking for
!== false.
Besides efficiency, the only difference between strstr() and strpos()
is what they return. strpos() returns the index of the first match,
while strstr() returns the entire string starting from that point;
it's the building of the copy of the string that causes strstr() to be
less efficient.
Both functions have case-insensitive variants stristr and stripos.
In each case, if the substring occurs more than once within the outer
string, the return value is based on the *first* occurrence. strpos()
(but not strstr()) has a variant that uses the *last* one instead:
strrpos() (r=reverse), which also has a case-insensitive version
strripos(). You can easily define a strrstr() though:
function strrstr($where, $what) {
$pos = strrpos($where, $what);
return $pos === false ? false : substr($where, $pos);
}
And for good measure, a strristr:
function strristr($where, $what) {
$pos = strripos($where, $what);
return $pos === false ? false : substr($where, $pos);
}

$name = John Taylor;

[PHP] objects stored in sessions
Hi All, I've got something on my little mind, and please keep in mind I'm still somewhat new to PHP Oop, so please excuse my silly ass if I ask something that should be obvious. I've got an application that I'm re-writing from PERL to PHP Oop. At the beginning of the application, at log in, a session is created for this user. What I would like to do is create a user object and store object properties in that session. So, if I create a user object, set the properties of said user object and store that object in the user session will that object be available throughout the application from the session? thanks, -- Mark - the rule of law is good, however the rule of tyrants just plain sucks!

Re: [PHP] Arbitrary mathematical relations, not just hashes
As far as languages with two-way relation go, there are many; perhaps
the most prototypical is Lisp, in that either member of a pair within
an alist can be used to look the pair up, with no extra function or
second map definition required.
But PHP has pretty good support, too, actually. If you have a 1-to-1
relation, you can use array_flip() to get a second array with the keys
and values swapped in one go. If you have a 1-to-many, as in this
case, you can use the optional search parameter to array_keys:
$color = array('apple' = 'red', 'ruby' = 'red', 'banana' = 'yellow');
array_keys($color, 'red')
Array
(
[0] = apple
[1] = ruby
)

Huh, didn't notice the cross-posting. But no, you're not subscribed

Since we're cross-posting, the translation of my sample would be
apropos. Here are a few different takes on a loopless versions in
Ruby. Given:
color = { :apple = :red, :ruby = :red, :banana = :yellow }
This is, I think, the most straightforward:
color.keys.find_all { |k| color[k] == :red }
But having to repeat the hash name is inelegant. Which leads us to this:
color.find_all { |k,v| v == :red }.collect { |p| p[0] }
Building up a list from the elements of a Hash would seem to be a
natural application of Hash#inject, although the fact that the inject
block has to return the accumulator makes it a little less elegant
than it could be, IMO:
color.inject([]) { |a,p| a p[0] if p[1] == :red; a }
In Perl5 I don't have a better solution than the first one above:
my %color = ( apple = 'red', ruby = 'red', banana = 'yellow');
grep { $color{$_} eq 'red' } keys %color;

[PHP] Cookie Trouble: getting the information back out...
Hi all,
I suspect I already know part of the answer to this, but I'm not sure
which way to go with it. I've got a project I'm working on and one of
the things it's got to do is set cookies and then read them later. When
the app was first written I was doing everything in PERL and cookies are
fairly straight-forward, however I'm finding cookies in PHP somewhat
problematic.
Setting the cookie is a snap, however getting the info back out is,
well... problematic.
this is basically what I'm doing, what I'm seeing in the cookie, and
what I'm getting back out.
Setting the cookie
==
$values = blah|blah|blah;
setcookie(cookiename, $values, time()+$timevalue);
Inside the Cookie
==
Content: blah%7Cblah%7Cblah
Getting info Out Of Cookie
==
list($first,$second,$third) = explode(|, $values);
Cookie Test Page
==
if (isset($_COOKIE[cookiename])){
list($first,$second,$third) = explode('|',$_COOKIE[cookiename]);
echo pI found your cookie/p\n;
echo pThe following Values were Contained in the cookie:BR
Username: $firstBR
Password: $secondBR
Type: $third/p\n;
}
else{
echo pI wasn't able to find your cookie./p\n;
}
Now, I've constructed a cookie_test.php page to check things out and the
strange behavior I'm seeing is, upon first execution I get the else
block, but if I hit the browser's reload button I get the if block. At
first I thought the cookie wasn't being read at all because of weird
characters, but then upon reloading the page and seeing the if block
being displayed I'm thoroughly confused. It's gotta something simple I'm
missing.
and I swear if someone tells me to RTFM I'm gonna shit and go blind
cause I haven't got a clue as to which part of the FM to read
concerning this. :)
thanks,
--

Is this block of code executed immediately after the cookie is
set? Sometimes PHP works too fast for its own good and the client
doesn't even realize it has a cookie yet. Try setting it with one
page and either sleep()'ing for a bit or forcing a link-click or page
refresh before checking for the cookie.
Um... Cookie data ISN'T available to the same script that sets it. If
you use setcookie(), all it does is send a header to the browser
immediately ahead of the output of your script telling the browser to
store those values in either memory or on disk. The value will not
appear in the $_COOKIE array until the browser requests the next page
and includes the Cookie: header as part of the request.
The part of the manual that applies is this line:
Once the cookies have been set, they can be accessed on the next page
load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.
$_SESSION variables are available immediately as soon as you set them.
The session cookie still isn't set on the client until the browser
processes the response headers at the end of the transaction, but the
values are already in the array and, if the session cookie works they
will be accessible on successive requests.

The problem that you are encountering is because the $_COOKIE array is
populated when the script is executed. More then likely the other
languages that you used, would allow you to set a cookie and then they
would enter them into the global array for you, and not make you wait
until the next page load.
You could accomplish this yourself by making a wrapper function for the
setcookie() function and have your function set the data using
setcookie() and having it enter the data directly into the $_COOKIE array.
Something like this should do the trick
?php
/*
bool setcookie ( string $name
[, string $value
[, int $expire
[, string $path
[, string $domain
[, bool $secure
[, bool $httponly ]] )
*/
function mySetCookie($name,
$value=null,
$expire=0,
$path='/',
$domain=null,
$secure=FALSE,
$httponly=FALSE) {
if ( is_null($domain) )
$domain = $_SERVER['SERVER_NAME'];
if ( setcookie( $name, $value, $expire,
$path, $domain, $secure, $httponly) ) {
$_COOKIE[$name] = $value;
return true;
}
return false;
}
?
Wow! very sweet!!
Thank you Jim. I'm getting my brain good and wrinkled today.

Log Directory permissions: /mystuff/logs rwx-rwx-rwx
(777)
Log file permissions: /mystuff/logs/run.log rwx-rwx-rwx
(777)
At any rate, the following is the information I'm getting in the apache
error_log while working on this particular portion of the application:
PHP Warning: fwrite(): supplied argument is not a valid stream resource
in /mystuff/inc/Log.inc on line 22,
PHP Warning: fclose(): supplied argument is not a valid stream resource

The Log class:
-
class Log{
public $path, $entry, $logfile;
public function Log(){}
public function setLog($path,$file){
$this-path = $path;
$this-logfile = $file;
}
public function writeLog($entry){
// open the file, in this case the log file
$h = $this-path/$this-logfile;
fopen($h, 'a+');
fwrite($h,$entry);
fclose($h);
}
}
Code snippet where attempting to write log entry from program:
$pl_log = new Log;
$pl_log-setLog($logpath,run.log);
$usernanme = $_POST['username'];
$password = $_POST['secret'];
/**

$pl_log-writeLog(getDateTime(): Incoming values from Login
Form:
blah...blah...blah\n);
Any help with this would be most appreciated. (be gentle... I'm a PERL

As Stut pointed out, you've misunderstood the difference between a file
resource and a file name.
Try something like:
public function writeLog($entry)
{
// open the file, in this case the log file
$fileName = $this-path.'/'.$this-logfile;
$h = fopen($fileName, 'a+');
fwrite($h,$entry);
fclose($h);
}
The file resource that fwrite and fclose need is the *result* of opening
the file, not the file name as you were doing.
Ideally, you would check the value of $h after the fopen call, to make
sure that it had successfully opened the file.
Also, I changed the way you were constructing the file name:
interpolating the variables in a string is slightly less efficient than
concatenating the bits together, and there are possible gotchas when
using the $this-variable structure in a string like that.
An alternative syntax is to escape the variables with braces:
$fileName = {$this-path}/{$this-logfile};
Hi Peter,
Thank you for that information. I'm rather new at this sort of PHP
coding and a bit embarrassed at the amount of OOP I've forgotten since
college. Clearly there's a lot to learn. Like this concept of escaping
you've mentioned. Until now the only type of escaping I'm familiar
with from PERL is something like this: \$$some_dollar_amount, but I have
a feeling escaping things in PHP oop is quite a bit different. I
haven't quite gotten my head around some of the stuff I've been reading
about, but it's coming.

[PHP] forms and php
I am fairly new to the php/mySQL combo and just noticed an unusual behavior and don't know where to find the answer to fix this. It is probably common knowledge, but not to a newbie. If I fill in the fields of a form and hit the enter key to submit the form, no variables seem to be passed along. If I use the submit button, everything works perfectly. It seems that other forms on the web work with the enter key just fine, so I am probably doing something to cause this yet I don't know what. I am hosted at hostgator.com and it has php version 4.4.4 and mySQL version 4.1.22-standard. Thanks, Mark Pashia
