Repost as I got zero replies. Does anyone know why this is? Seems like a bug
to me, or at least should be documented as such whacky behavior. Are there
any solutions to this or work-arounds?

Why does it give me sub-objects and not just empty strings for tags that
have no values as I'd expect??!
I tried all those options above and none of them make a difference.

[PHP] I've some doubts if I should go with 5.2 or go already with 5.3 (for a course)
I'm giving a PHP course next semester (3 hours all saturdays for 22 weeks) and I just realized that PHP 5.3 is coming very soon (2 days now!). So, my plans of teaching PHP 5.2 are starting to change, and I think it's a good idea to teach them 5.3 already. While the majority of the students use Windows, I'm aware that a vast amount will be using Ubuntu/Debian (and some use Gentoo, Fedora and Arch) distributions of Linux, so I'm hoping there won't be too many problems on installation. I don't want to waste the entire first class fixing installation problems, because that kills the student's motivation. The course starts on August, but I'm preparing it during the last two weeks of July. You think that installation packages will be bulletproof by then? Or should I just teach 5.2 and wait for another semester before starting on 5.3? I mean, most hosts will remain with PHP 5.2 for the rest of the year, so I'm a bit confused on what I should do. I'm just a university student that wants to spread PHP, for I've been using it for many years now =) Thanks for the advices, Mamsaac

Why not give a presentation, like in the first few, about compiling PHP for yourself, as that's a pretty useful skill that's oft neglected?

Well I'd imagine the vast majority of your course will be covering the basic principles of PHP coding, techniques, GPP, frameworks etc. Generally most people will want to use a Framework, (Zend, Cake, etc.) which will take a while to adopt PHP 5.3 anyway (some still support PHP4 so what hope is there to use features of PHP5.3 anyway soon!) so I'd suggest teaching the basics on a PHP5.x system and then perhaps spend two or three sessions at the end covering the newer stuff from PHP 5.3. That's probably the way I'd go, and you can give people some prior warning to try and get a PHP 5.3 install up and running for the x'th week of the course.

I getting data from a form with POST method like following. $x = htmlentities($_POST['y']); . After getting all form daha I save them into DB, I used mysql_real_escape_string. Don't try to home brew your own. You'll miss stuff. Use an input filter class that is developed by and tested by a large number of users. http://htmlpurifier.org/ is what I recommend. Also, with respect to mysql_real_escape - if you use prepared statements, escaping isn't an issue. Personally I recommend a database extraction later. Pear MDB2 is a good one. It makes your code portable to other databases as long as you stick to standard SQL (which usually is pretty easy to do).
Re: [PHP] I've some doubts if I should go with 5.2 or go already with 5.3 (for a course)
The thing is, that part of the planned course was to develop a small framework, so that they could see the dynamic and OOP posibilities that PHP offers. With PHP 5.3, there are namespaces, which change a lot the design of a framework, as well as true lambdas with closures. So, naturally, the architecture of this minimalistic framework changes and I have plans to write it before the course starts. Why a framework? If you know how an MVC framework is created and how it works, you will most likely get into Zend Framework or CakePHP much faster. Plus, it's a very good way to learn the language. It wouldn't be the first one I've written, so it's not much trouble. That's why I care about PHP 5.3. Now imagine if there were Traits! Anyway, I think I will do as someone mentioned, and teach them 5.2 during the entire course and then at the end show them some of 5.3. -- Forwarded message -- From: Per Jessen p...@computer.org To: php-general@lists.php.net Date: Tue, 23 Jun 2009 10:12:55 +0200 Subject: Re: [PHP] I've some doubts if I should go with 5.2 or go already with 5.3 (for a course) Manuel Aude wrote: I'm giving a PHP course next semester (3 hours all saturdays for 22 weeks) and I just realized that PHP 5.3 is coming very soon (2 days now!).

Using package repositories for php installs is suggested as security fixes can be updated with ease. As someone running a newer version of php (5.2.9) than what my distro ships with, here are some of the issues: A) I needed to create packages so that I could RPM install various stuff, like Squirelmail, etc. - and get the security updates for them from my OS vendor (CentOS or EPEL repods). So to do that, I used the Fedora src.rpm. B) When building php rpm's on my system, the %check portion of the spec file (runs make test I believe) fails sometimes if there is an existing php install. To solve that, you have to build it in mock. C) Mock needs a lot of disk space and will download a lot of packages, if you don't local mirror the update repositories, it can be really time consuming. Furthermore, occasionally the build list for mock is broken making it un-usable for package building. I have to use 5.2.x because I need a pecl extension that does not work with 5.1.x - and building rpm myself lets me add suhosin patch (to the fedora spec file) but unless your Linux students want to do absolutely everything php by source and not have anything installed from the package managers that rely on php, I would highly suggest that they use whatever version of php their distro of choice has in its stable repositories. -=- Since you are teaching students, one pet peeve of mine that I see in web app after web app after web app - they have an admin interface that writes a php file which the app then parses as php. Often they even instruct the person installing the web app to have 777 permissions of directories and/or files within the web root. There's a better way. Either store the configuration settings in a database (obviously can't store database connection setting in the database ...) or store them in an xml file, not php. You can write and read the xml file with any number of existing php functions. And the config file should not be in the web root, nothing the web server can write to should be in the document root. Applications (like Gallery and I think joomla and wordpress) often want write permission to the document root so they can have a web interface to install/update their modules - but it creates a security risk. It's better to install the modules you want from a distro vendor repository so you can keep them up to date that way, and hence, it's better to use a packaged php install so that the dependencies are met. Sorry for rambling, but the trend of web server having write permissions to files the web server then executes (and often in the web root) is a trend that needs to stop.

[PHP] Echo result in a loop on each instance
I have a question regarding echo of a var/string in a loop on each instance
A shortened example:
Lets say I have an array of values (rather big), and then I loop
through this array:
for or foreach :
{
$value = $arrValAll[$i];
echo test.$i.-- .$value;
}
When the script runs it will only start to echo values after certain
period ... it does not echo immediately ... how can I force it start
echo as soon as the first echo instance is done ? I thought ob_start
does this but I have tried it and not getting what I want.
Is there some other way/correct to do this?

I have a question regarding echo of a var/string in a loop on each instance
A shortened example:
Lets say I have an array of values (rather big), and then I loop

for or foreach :

$value = $arrValAll[$i];
echo test.$i.-- .$value;
}
When the script runs it will only start to echo values after certain
period ... it does not echo immediately ... how can I force it start
echo as soon as the first echo instance is done ? I thought ob_start
does this but I have tried it and not getting what I want.
Is there some other way/correct to do this?
call flush() after each echo to flush the buffer to the client.
That should work...

So, my plans of teaching PHP 5.2 are starting to change, and I think it's a good idea to teach them 5.3 already. While the majority of the students use Windows, I'm aware that a vast amount will be using Ubuntu/Debian (and some use Gentoo, Fedora and Arch) distributions of Linux, so I'm hoping there won't be too many problems on installation. I don't want to waste the entire first class fixing installation problems, because that kills the student's motivation. The course starts on August, but I'm preparing it during the last two weeks of July. You think that installation packages will be bulletproof by then? Or should I just teach 5.2 and wait for another semester before starting on 5.3? I mean, most hosts will remain with PHP 5.2 for the rest of the year, so I'm a bit confused on what I should do. I'm just a university student that wants to spread PHP, for I've been using it for many years now =) Many hosts are still on php 5.1.x (IE RHEL based hosts). I would be worried that many popular classes and apps might be quirky under 5.3. I've not played with it at all, and probably won't for some time, but I've been bitten by that more than once. Nice thing about 5.2.x as far as linux goes anyway, installing it is cake from the package repositories. Using package repositories for php installs is suggested as security fixes can be updated with ease. As someone running a newer version of php (5.2.9) than what my distro ships with, here are some of the issues: Manuel, You might want to check on the release schedules for PHP 5.3(.1?) by the major distributions. Even if they are close to the end of your class schedule, will they be deployed that quickly to sites your students could be working on? Or will they still be working with 5.2 for the foreseeable future? I have recently been told that we are switching from compiling Apache, PHP and PostgreSQL ourselves to only using the official RedHat RPMs on our production servers[*]. This is coupled with a move to a managed hosting service. But since RH is not even shipping the most recent version of 5.2, I don't expect to see a 5.3 RPM for some time. Maybe it will have enough improvements to trigger an early update from them, but who knows. After they release it, it will still be a while before we pick it up, test it and deploy it. So even though I like some of the changes in 5.3, I am stuck with 5.2 for at least another year, maybe two. Bob McConnell [*] No, I don't like this at all. I see it as the antithesis of both the Open Source and Free Software philosophies. It means we give up control of some of the options we were selecting at compile time and have to settle for somebody else's idea of the perfect server.

interesting that it is possible to use another file for the action - but
that seems a bit redundant as you have to populate that file with almost
the same stuff that is in the original form file...
I'm making progress, but I don't think I'm learning a lot other than to
contain my frustration. ;-)
if(is_numeric($bid)) {

After this code there will always a number, If the id variable is 0, bid
will be 0 and you can control it.

Hi Caner,
Thanks for the input. I'm not sure that would do it as the first
instruction on the page is :
$bid = $_GET['id'] ;
thus, the page cannot even be loaded if there is no id in the uri - it
generates a number of errors.
In order to use the feature of editing, I use a search page and then set
up an href to the edit page with the id of the item to be edited.
I finally figured out to do the action=another_page.php and with
slight modifications to the form, things finally work.
And, to delete the item (all records related to the item), I set up 2
submits - 1 to update.php and one to delete.php
Maybe it's all cumbersome and maybe it is possible to streamline the
whole process, but then it does work and I am just learning... :-)
Thanks again.

Hi,
You can use a variable to that. Like following. Example if the variable
is 1
you start to processing form input.
Example
form method=post action=file.php?action=1
And in file.php you check the action variable if it is 1 you can start
the
processing data.
If($_GET['action']==1) {
Echo done;
}
Thanks.

Subject: [PHP] resubmit form after validation error
I'm having a bit of a time figuring out how to resubmit a form after
obligatory field missing error.
The problem is that the page is accessed from a search page href where
the uri is like = file.php$=123.
Since the method=post action=file.php?=?php echo $number; ? does
not work nor does PHP_SELF, I have set the action=otherfile.php. All
is well, if all fields are properly entered, but if there is an error,
how to resubmit the form for correction and resubmission without using
js or functions or redoing it all from scratch?

The performance hit isn't that great, and now you're potentially storing more data since individual characters (generally 1 or 2 bytes) are inflated to entities that are often around 6-8 bytes. Additional Cons: If the content ever needed to be formatted for something other than html (either now or in the future) you'd have to remove the entities every time you read the database. So now you have a stupid wast of performance again AND you're still storing the extra bytes in the database.

Cons: 1. Can't easily edit information in the database 2. Can't display raw for the user (e.g. edit a forum post) 3. Uses more space in the DB 4. Isn't as easily indexed 5. Breaks il8n support of internal search engines (sphinx, lucene, etc.) You're NEVER supposed to santize before inserting in the DB. Ever. Regarding the performance boost, if your application is written so well that calling htmlentities() is hurting the performance, I bow to you as writing the highest performing PHP I've ever seen.

$kvpair is modified, but that change is ignored by implode() with

So why doesn't the change to $kvpair get brought in by implode? What

Here is the sequence I am trying to implement without the database
portion. (This is typed in since the VNC I am using doesn't support
pasting from a Linux client to a MS-Windows server.)
-
$buff = key1|value1~key2|value2;
$lines = explode (~, $buff);
foreach ($lines as $kvpair) {
$line = explode (|, $kvpair);
if ($line[0] == key1) {
$line[1] = value3;
$kvpair = implode (|, $line);
break;
}
}
$newbuff = implode (~, $lines);
-
$kvpair is modified, but that change is ignored by implode() with
$newbuff still containing key1|value1.
So why doesn't the change to $kvpair get brought in by implode? What
should I do to update that value?
Bob McConnell
See the second note at
http://www.php.net/manual/en/control-structures.foreach.php
Either of these should do what you want:
?php
$buff = key1|value1~key2|value2;
$lines = explode (~, $buff);
foreach ($lines as $kvpair) {
$line = explode (|, $kvpair);
if ($line[0] == key1) {
$line[1] = value3;
$kvpair = implode (|, $line);
break;
}
}
$newbuff = implode (~, $lines);
?
?php
$buff = key1|value1~key2|value2;
$lines = explode (~, $buff);
foreach ($lines as $key = $kvpair) {
$line = explode (|, $kvpair);
if ($line[0] == key1) {
$line[1] = value3;
$lines[$key] = implode (|, $line);
break;
}
}
$newbuff = implode (~, $lines);

Not to mention, every error thrown is overhead in the system, regardless if it is being displayed or logged. (as Rasmus says, write error free code) Behavior changes that can affect people's code from either the I assume this is defaulted this way, behavior changes or deprecation changes from what I can grok from that - quite a few that people should probably be looking for ahead of time, and writing 5.3 safe versions of their code, and ensuring they have the ini variables defined to what they want that will be changing their defaults too... - **namespace** and **goto** are now reserved keywords. - **Closure** is now a reserved class. (Used by lambda and closure.) - The array functions natsort(), natcasesort(), usort(), uasort(), uksort(), array_flip() and array_unique(), no longer accept objects passed as arguments. If you need to access their properties using an object, you will need to cast the objects to arrays first. - The behaviour of functions with by-reference parameters called by value has changed. Where previously the function would accept the by-value argument, a warning is now emitted and all by-ref parameters are set to NULL. - The magic methods __get(), __set(), __isset(), __unset() and __call() should always be public and can no longer be static. Method signatures are enforced. - The __toString() magic method can no longer accept arguments. - count() vs count_elements() handler resolution rules have changed. (This could potentially break custom PHP extensions.) - The trailing / has been removed from SplFileInfo and other related directory classes. - The new mysqlnd library necessitates using MySQL's newer 41 byte password format. Continued use of the old 16 byte passwords will cause mysql_connect() to produce the following error message: mysqlnd cannot connect to MySQL 4.1+ using old authentication (perhaps an E_WARNING ?) - define_syslog_variables() is deprecated.(not sure if this will throw any E_DEPRECATED or anything) - All ereg functions are deprecated and emit E_DEPRECATED errors. Use PCRE (preg_*()) instead. - The following ini directives will now emit an E_DEPRECATED warning upon startup if they are activated: - define_syslog_variables - register_globals - register_long_arrays - safe_mode - magic_quotes_gpc - magic_quotes_runtime - magic_quotes_sybase Extensions moved out to PECL and actively maintained there - fdf - ming - ncurses c. with changed behaviour - datetime: date/timefunctions will no longer use the TZ environment variable to guess which timezone should be used. - hash: The SHA-224 hash algorithm is now supported. - oci8: Calling oci_close() on a persistent connection, or on a variable that references a persistent connection going out of scope, will now roll back any uncommitted transaction. You should explicitly commit or rollback as needed. Setting oci8.old_oci_close_semantics=On in php.ini gives the old behaviour. - session: Sessions will no longer store session-files in /tmp where open_basedir restrictions apply, unless /tmp is explicitly added to the list of allowed paths. - zend_extension_debug and zend_extension_ts have been removed. Instead use the zend_extension directive to load all Zend Extensions. - zend.ze1_compatibility_mode has been removed. If this ini directive is set to on, then an E_ERROR is emitted at startup. - The default value of session.use_only_cookies has changed to 1 Windows has some changes too, but I think only if you're running pre Windows 2000 will it make a difference.

If you don't do html...() before putting to textarea this can happen: textarea blabla b/textarea blabla /textarea See? 3. Uses more space in the DB True, although I use htmlspecialchars() which doesn't replace that many characters. That makes it no better of a practice to pre-sanitize. You've still yet to offer any compelling reasons why you think this is a good idea. It's DEFINITELY easier to store RAW data to DB, because it won't give you any headaches in the future - when you might need to add some other functionality requiring this.

[PHP] modifying within foreach
In the following example:
foreach ($results as $key = $item) {
//bla bla bla -- unset some of the $items
}
I want to modify $results within the foreach. In other words,
during a given pass of this iteration, I want to delete some
of the items based on particular conditions. Then on the next
pass thru the foreach, I want $results to be the newer, modified
array.
This does not seem to work. It appears that the foreach statement
is implemented such that $results is read into memory at the start
so that any modifications I make to it during a given pass, are ignored
on the next pass. Is this true?
If so, is there a way that I can tell the foreach statement to re-read the
array $results? Or am I just going against the grain here?

[PHP] best way to communicate between PHP, Flash/Actionscript across LAN
I have a demo to create for a tradeshow. We have 3 touch screens and 3 50 plasmas and 3 G1 (android WiFi) phones. Our own LAN/Router/Wi-Fi. I need a way so that I can use web pages and Flash (actionscript) to make stuff happen on any of the displays/phones. So you click a button on the touch screen and see something happen on the plasma. Or G1 interface application triggers .flv on touch screen, etc. So I need some kind of messaging queue over the LAN and that each CPU can both send and recieve? I could use mySQL as an intermediary to store the data (like strings of text entered or whatever and pass the record IDs around), or use some other XML/JSON/AJAX or something. I just don't even know what I'm talking about really. Is this what DBUS is for? It must work with PHP as we'll have web pages triggering the .flv as well and of course ActionScript has to be able to work with it (that's why I was thinking mySQL, AJAX, XML, etc.). Ideas? Suggestions? someone was telling me about AMQP or RabbitMQ. But neither is PHP-ified that I can tell. http://www.nabble.com/PHP-AMQP-client--td12935751.html ...and I realize that PHP will run in a web page mostly and I'll have to do some magic like polling something (like a daemon or DB) via JS/AJAX to see if I need to pop-up an alert or whatever -- much like a bulletin board does when you get new mail.

[PHP] Deleting a file after download/upload
Hi there, I am writing a PHP FTP client for my project. I want to put a download option and an upload option, but I don't know how. My problem is this: How can I make the server the PHP script is on delete the file after uploading it to the SFTP, or after the user has finished downloading it from the server the PHP script is on? Let me put the question this way. My server connects to an FTP. Then, it downloads a file from the FTP, and then sends me the link to that temperary file on the server. Now, when I download it from my server, my script should delete the file. How can I make it wait until the download of the file is finished? Same goes for uploading.

Re: [PHP] modifying within foreach
I do not want to delete the whole array, only a particular $item.
given this $results array:
Array
(
[key1] = Array
(
[0] = value1
[1] = value2
[2] = value 3
(
[key2] = Array

It is a value item that I want to delete based on a particular criteria.
In each pass I may delete a value item. However, it seems that each
subsequent pass operates on the original $results array and not
the modified one.

RE: [PHP] modifying within foreach
Dude. Use your common sense and the example I just provided:
foreach ($results as $key = $item)
{
if ($item == 'foo')
unset($results[$key]);
else ($item == 'bar')
$results[$key] = 'new value';
}
so using your example:
foreach ($results as $key = $item)
{
if ($item[0] == 'value1')
unset($results[$key][0]);
else ($item[0] == 'bar')
$results[$key][0] = 'value4';
}
But since you have a multidimensional array, you have to really do two loops
to be useful:
foreach ($results as $key = $item)
{
foreach ($item as $i = $value)
{
if ($value == 'value1')
unset($results[$key][$i])
else ($value == 'bar')
$results[$key][$i] = 'value4';
}
}
Or something to that effect, I just wrote that freehand, but you should get
the idea.

Hi all! Built an appointment scheduling app, but now the client wants it to send out an email with the appt attached in iCal format. I've never dealt with anything iCal before. I searched around a bit, and know that there iCal php scripts available, but I don't need a bunch of rigamarole, just need to create the attachment and send it on the fly. But I'm having trouble finding the format. Anyone know what this looks like? Or can point me to a resource? Rather not scrounge thru someone else's code, or have to install something just to run it for the format...if I can help it. :) Thank you, Jason

Hi PJ,
You can use the structure following

YOU, always need to have error_reporting on and display errors on, and
also be logging errors so that you can see parse errors in the log.
Always check the log after a empty screen. I've seen many posts from
you where you get a blank, empty, white screen. This is most always a
parse error!. Get an editor that will show you bad syntax like the
above. It is a freaking parse error because you don't have matched
parentheses!
Shawn, I always have error_reporting on and display errors on.
Ok, I didn't see the error above; but in my defense (no defense really),
I should have thought about it) i just copied the code I was given.
Dumb, dumb, dumb. Thanks for pointing it out.
And yes, I do have a lot of problems with curly braces parentheses.
I eventually do find them... but...
I have been thinking about what editor would show me bad syntax...
I've been using HOMESITE+ for no other reason than that it allows me to
switch between files quickly ... I do have Netbeans, but it screwed me
once when I accidentally closed it and I lost the whole file and had to
redo it all, so I'm a bit wary...
And I'm not too keen on getting into some IDE... tried them and found
them cumbersome to set up learn.
Any suggestions?

Re: [PHP] I've some doubts if I should go with 5.2 or go already with 5.3 (for a course)
Let's put it this way: MVC frameworks with namespaces are going to change a lot. The architecture can be made much cleaner and class names won't have to be so long (Zend_Db_Adapter_Db2_Exception), for instance. The design part of coding is __VERY__ important, and this changes are specially for that. See PHAR extension, which will be enabled now, which allows for easier distribution of software. And closures, which simply have so many uses in design and save you from clustering your code with too many function names. Sure, it doesn't change the language, and it doesn't really break apps that were written in PHP 5.2, but if you're going to design an application, thinking about this options is very useful. Too bad we don't get Traits yet =( Horizontal re-use is very nice.

So, my plans of teaching PHP 5.2 are starting to change, and I think it's a good idea to teach them 5.3 already. While the majority of the students use Windows, I'm aware that a vast amount will be using Ubuntu/Debian (and some use Gentoo, Fedora and Arch) distributions of Linux, so I'm hoping there won't be too many problems on installation. I don't want to waste the entire first class fixing installation problems, because that kills the student's motivation. The course starts on August, but I'm preparing it during the last two weeks of July. You think that installation packages will be bulletproof by then? Or should I just teach 5.2 and wait for another semester before starting on 5.3? I mean, most hosts will remain with PHP 5.2 for the rest of the year, so I'm a bit confused on what I should do. I'm just a university student that wants to spread PHP, for I've been using it for many years now =) Thanks for the advices, Mamsaac Many hosts are still on php 5.1.x (IE RHEL based hosts). I would be worried that many popular classes and apps might be quirky under 5.3. I've not played with it at all, and probably won't for some time, but I've been bitten by that more than once. Nice thing about 5.2.x as far as linux goes anyway, installing it is cake from the package repositories. Using package repositories for php installs is suggested as security fixes can be updated with ease. As someone running a newer version of php (5.2.9) than what my distro ships with, here are some of the issues: A) I needed to create packages so that I could RPM install various stuff, like Squirelmail, etc. - and get the security updates for them from my OS vendor (CentOS or EPEL repods). So to do that, I used the Fedora src.rpm. B) When building php rpm's on my system, the %check portion of the spec file (runs make test I believe) fails sometimes if there is an existing php install. To solve that, you have to build it in mock. C) Mock needs a lot of disk space and will download a lot of packages, if you don't local mirror the update repositories, it can be really time consuming. Furthermore, occasionally the build list for mock is broken making it un-usable for package building. I have to use 5.2.x because I need a pecl extension that does not work with 5.1.x - and building rpm myself lets me add suhosin patch (to the fedora spec file) but unless your Linux students want to do absolutely everything php by source and not have anything installed from the package managers that rely on php, I would highly suggest that they use whatever version of php their distro of choice has in its stable repositories. -=- Since you are teaching students, one pet peeve of mine that I see in web app after web app after web app - they have an admin interface that writes a php file which the app then parses as php. Often they even instruct the person installing the web app to have 777 permissions of directories and/or files within the web root. There's a better way. Either store the configuration settings in a database (obviously can't store database connection setting in the database ...) or store them in an xml file, not php. You can write and read the xml file with any number of existing php functions. And the config file should not be in the web root, nothing the web server can write to should be in the document root. Applications (like Gallery and I think joomla and wordpress) often want write permission to the document root so they can have a web interface to install/update their modules - but it creates a security risk. It's better to install the modules you want from a distro vendor repository so you can keep them up to date that way, and hence, it's better to use a packaged php install so that the dependencies are met. Sorry for rambling, but the trend of web server having write permissions to files the web server then executes (and often in the web root) is a trend that needs to stop. So flunk the students that do it ;) And how do you propose people get around open_basedir restrictions which is common in many Plesk environments? There is nothing wrong with having the above mentioned write access if it is properly protected. Nothing wrong other than any vulnerability in apache (or a module apache loads or cgi/server script code) that allows a malicious user to write data as the apache user can now do so inside the web root where they can then request it causing php/perl/python/whatever to execute the code they just wrote. Every single web host I have ever used that has a shell account given me a directory that is not inside the web root.

[PHP] PHP module portability on OSX 10.4
I know this is a bit OS specific but it's for PHP so I'm hoping someone here has run into it before and can answer. I've compiled php_gd.so for use on an XServe running OSX 10.4. It works fine there. When I copy it to another XServe it fails because of missing dependencies (don't remember the exact error but that was the jist of it). I used otool -L php_gd.so and got the following... php_gd.so: /usr/local/lib/libpng12.0.dylib (compatibility version 33.0.0, current version 33.0.0) /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.11) libz.1.dylib and libSystem.B.dylib exist on a raw machine so I assume it's just the libpng. So... Can I just ALSO copy the libpng file, drop it in the right place and have it work? It seems like it should work... but at the same time, something in my head is telling me it shouldn't work... Barring that does anyone have steps written down that I can follow to compile php_gd.so with libpng compiled in somehow so it is only one file? Thanks in advance!

Hi PJ,
You can use the structure following
$bid = htmlentities($_GET['id']);
the code below
if(empty($bid) {
$bid=0;
}
produces an empty screen with no error messages...
I have been having some trouble understanding empty() -- it doesn't
seem to want to work for me in any situation
YOU, always need to have error_reporting on and display errors on, and
also be logging errors so that you can see parse errors in the log.
Always check the log after a empty screen. I've seen many posts from
you where you get a blank, empty, white screen. This is most always a
parse error!. Get an editor that will show you bad syntax like the
above. It is a freaking parse error because you don't have matched
parentheses!
Shawn, I always have error_reporting on and display errors on.
Ok, I didn't see the error above; but in my defense (no defense really),
I should have thought about it) i just copied the code I was given.
Dumb, dumb, dumb. Thanks for pointing it out.
And yes, I do have a lot of problems with curly braces parentheses.
I eventually do find them... but...
I have been thinking about what editor would show me bad syntax...
I've been using HOMESITE+ for no other reason than that it allows me to
switch between files quickly ... I do have Netbeans, but it screwed me
once when I accidentally closed it and I lost the whole file and had to
redo it all, so I'm a bit wary...
And I'm not too keen on getting into some IDE... tried them and found
them cumbersome to set up learn.
Any suggestions?
If you are on Winbloze, I thing the free notepad++ has syntax
highlighting for PHP.

When I wanted to search for something and amp; was in the value, typing would not find the result. I fixed that by not using htmlentities() before inputing data into the database. IMO, using htmlentities() or htmlspecialchars() before inserting into db is inherently wrong. Making calls to those functions should have negligible impact on the application - there are other ways to improve the performance of your application.

[PHP] Re: Deleting a file after download/upload
Parham Doustdar wrote:
Hi there,
I am writing a PHP FTP client for my project. I want to put a download
option and an upload option, but I don't know how. My problem is this:
How can I make the server the PHP script is on delete the file after
uploading it to the SFTP, or after the user has finished downloading it from
the server the PHP script is on?
Let me put the question this way.
My server connects to an FTP. Then, it downloads a file from the FTP, and
then sends me the link to that temperary file on the server. Now, when I
download it from my server, my script should delete the file. How can I make
it wait until the download of the file is finished?
Same goes for uploading.
Thanks!
Well if you write a download script, then you can delete it at the end
and it won't be deleted until after the download completes:
//Do your ftp from remote to local'/path/to/file.ext'
exec('ftp_get.sh remotefile.ext /path/to/file.ext);
//or
$conn_id = ftp_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
ftp_gett($conn_id, '/path/to/file.ext', $server_file, FTP_BINARY)
ftp_close($conn_id);
?php
//send proper headers for download
readfile('/path/to/file.ext');
unlink('/path/to/file.ext');
?
For upload, depending upon how you're doing it, a call to unlink()
shouldn't execute until your FTP is done and exited:
?php
//User uploads file to '/path/to/file.ext'
exec('ftp_put.sh /path/to/file.ext);
//or
$conn_id = ftp_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
ftp_put($conn_id, $server_file, '/path/to/file.ext', FTP_BINARY)
ftp_close($conn_id);
unlink('/path/to/file.ext');
