Hello.
I have an application that generete HTML5 form in PHP.
The form is written in a while loop and therefore the form field has exact
same name for every row in the loop.
And that is the problem. Because when my PHP document shall handle
submitted data it only take the very last row in the while loop and show
the result of it.
if(isset($_POST['update_explosive'])){
$item_serial_number = $_POST['item_serial_number'];
$update_item_in_store = $_POST['update_item_in_store'];
if($item_serial_number === ETX1.22X1000){
echo h1$update_item_in_store/h1;
}
if($item_serial_number === ETX1.17X460){
echo h1$update_item_in_store/h1;
}
}
I think the solution will be to create different and unike fieldname
dymamic. For example I tried to write input type=text name=?php echo
$item_serial_number; ? value=?php echo $item_serial_number; ? in
the HTML5/PHP form.
But the problem is that periode . not is allowed as $variable_name.
I then try to write it this way:
if(isset($_POST['update_explosive'])){
$item_serial_number = $_POST['ETX1.22X1000'];
$update_item_in_store = $_POST['update_item_in_store'];
if($item_serial_number === ETX1.22X1000){
echo h1$update_item_in_store/h1;
}
if($item_serial_number === ETX1.17X460){
echo h1$update_item_in_store/h1;
}
}
But this last part did not make any sense to me. I recive no output when
tried that one.
One problem is that I have between 2 and 25 items with different serial
number. Sometimes only 5 of this shall be updated and other times all 25
items. I like to do this through one simple form and not for one time for
every single item. (I know how to do when select one by one and update
them, but that is a long and hard way for people using my application. A
better solution is to just use one form and view all items there. Then just
write the amount of item in input type=number
name=update_item_in_store size=6 field.)
If you have time to help me *understand* this newbie question by explain or
give me an example or post a link to a tutorial that can help me though, I
am very thankful.

Make your names on your input tags like this:
if you currently have
input type='text' name='field1'
then change it to this:
input type='text' name='field1[]'
This will give you an array of in your POST/GET array.

The deal is that if you use the / then strtotime interprets it as m/d/y
and if you use - it interprets it as d-m-y.

Yes, I knew the '-' format would work, I just didn't know quite how to
convert the '/' to '-'. A very simple and clean solution.
The final form is:
function read_data($filename)
{
$f = fopen($filename, 'r');
while ($d = fgetcsv($f)) {
$ts = strtotime(str_replace('/','-',$d[0]));
$data[] = array($ts, $d[1]);

[PHP] Re: Newbie Question about Conditionals
Matty Sarro wrote:
Hey all!
This is probably my second post on the list, so please be gentle. Right now
I am running through the Heads First PHP and MySQL book from O'Reilly.
It's been quite enjoyable so far, but I have some questions about some of
the code they're using in one of the chapters.
Basically the code is retreiving rows from a DB, and I'm just not getting
the explanation of how it works.
Here's the code:
$result=mysqli_query($dbc,$query)
while($row=mysqli_fetch_array($result)){
echo $row['first_name'].' '.$row['last_name'].' : '. $row['email'] . 'br
/';
}
Now, I know what it does, but I don't understand how the conditional
statement in the while loop works. Isn't an assignment operation always
going to result in a true condition? Even if mysqli_fetch_array($result)
returned empty values (or null) wouldn't the actual assignment to $row still
be considered a true statement? I would have sworn that assignment
operations ALWAYS equated to true if used in conditional operations.
Please help explain! :)
Thanks so much!
-Matty
Others have explained in detail, but I will tell you why you and many
beginners may have been confused by this. On this list as well as in
other help sites for PHP, beginners post code that contains something
like this, and wonder why it always echoes TRUE:
$value = 'bob';
if($value = 'test') {
echo 'TRUE';
} else {
echo 'FALSE';
}
They normally get an answer such as: You need to use == for
comparison, = is an assignment operator and the assignment will always
evaluate to true. Well, this is true for this assignment because the
non-empty string 'test' evaluates to true. But without explanation it
may sound as though ANY assignment will evaluate to true just because
the actual assignment itself was successful. This is obviously not the
case. This echoes FALSE:
$value = 'bob';
if($value = '') {
echo 'TRUE';
} else {
echo 'FALSE';
}

Hi all,
When I do this:

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

Hi all,
A little doubt caught me while I was writing this snippet of code for
a wordpress template:
?php if (the_title('','',FALSE) != 'Home') { ?
h2 class=entry-header?php the_title(); ?/h2
?php } ?
I always thought that php was called only between the ?php ? tags,
and I'm pretty sure that's right, while HTML code was simply wrote in
document as is, without further logic.
Now, I can't figure out how this snippet works: I mean, shouldn't HTML
code be simply put on document, as it is outside php invoke?
Effectively if the title of page is 'Home', the HTML part is totally
skipped.

You made a mistake in your code:
?php the_title(); ?
must be:
?php echo the_title(); ?
?= the_title(); ?
also works.

Hi all,
A little doubt caught me while I was writing this snippet of code for
a wordpress template:
?php if (the_title('','',FALSE) != 'Home') { ?
h2 class=entry-header?php the_title(); ?/h2
?php } ?
I always thought that php was called only between the ?php ? tags,
and I'm pretty sure that's right, while HTML code was simply wrote in
document as is, without further logic.
Now, I can't figure out how this snippet works: I mean, shouldn't HTML
code be simply put on document, as it is outside php invoke?
Effectively if the title of page is 'Home', the HTML part is totally
skipped.
Is the if construct that does all the magic inside?

RE: [PHP] Re: Newbie: Composition by Association - Pagination Class general question.
As for (1) even in my pre-OO days I was used to using a single generic DAO for all database access. The only time that more than one DAO existed was for a different DBMS engine. This is why I have one DAO class for MySQL, one for PostgreSQL and another for Oracle. If you are incapable of writing a single generic DAO then it just shows that you still have a lot to learn. For an idea on how this works take a look at http://www.tonymarston.net/php-mysql/databaseobjects.html I'm absolutly sure that I have a lot to learn. Really a lot. :-) I have post some days ago, a way for using a generic CRUD class and DAO, but I get no replys so I wrongly suppose that my question was a nonsense question, and that CRUD and DAO would be a nonsense. As for (2) it should be obvious that pagination is not an entity in its own right that has its own properties and methods, it is merely a function which can be performed on any entity within the system. Ok... It should also be obvious that the requirements of pagination cannot be satisfied in a single class as some of the processing has to be handled in the presentation (UI) layer while the remainder is handled in the data access layer. That's why I was thinking on using a Decorator Object on the Pagination Class (that will retrieve DAO values to operate). The presentation layer needs a means to submit a request for a particular page number as well as the page size (rows per page). These two values are sent to the DAO which then translates them into values for LIMIT and OFFSET. After the DAO has issued the sql SELECT statement it needs to return two values - the current page number and the last available page number. The presentation layer then needs a mechanism to display these two values. This is explained in http://www.tonymarston.net/php-mysql/pagination.html Thanks for explain the workflow! I will read. If you still don't see how this works then you can run my sample application at http://www.tonymarston.net/php-mysql/sample-application.html You can even download the code so that you can step through it with your debugger. I haven't learn how to use a debugger yet. And I'm sure it would help me a lot on understanding some data workflow...

RE: [PHP] Re: Newbie: Composition by Association - Pagination Class general question.
Why not? Why can't you replace a call to a mysqli function with a call to a PDO function? It's not just a simple replacement - I need to add bindparam, prepare, execute, placeholders and fetchObject. But I will give it a try... Also, I also intend to use fetchObject method instead of fetchAssoc quite often, Why? What's the benefit? The fetchAssoc method gives you an array of values, while the fetchObject method gives you a container for an array of values. You still still have to work with an array of values. FetchObject maps the field names from the database as object properties with the values stored in the database. Seems quite nice. Then, to access a specific column data I just needed to: $myhandler-my_database_column_name (it seems quite nice to me) :) Why don't you learn how to use the mysqli functions before you handle the switch to PDO? What do you have to lose? I already work with PDO so, no need to switch. :-) If you read my tutorial you should see that building a SELECT statement is nothing more than combining several small strings into a larger single string. String manipulation is simple in PHP. Using this technique I can create very complex SQL statements, so don't tell me that it can't be done. I was not talking about your tutorial. I was talking about those two links, mainly the first one where, unfortunately, the difference between the code and the sql sintax is that we don't have the word SELECT and WHERE. :s However, as a positive point, this class uses BindParam and ? placeholders. But I get your point, we can cut it into smaller strings. Because you have less code to maintain. If you look carefully you should see that the only difference between the DAO for TableA and the DAO for TableB is the table name and the table structure. If you could pass these as arguments into a generic DAO then you would not need a separate DAO for each table. Yes. But you still need, for each table, to fill one or several (depending on what mysql connection method we use) arrays with values. So that less code maybe isn't that much in a way where you *significantly* reduce your maintenance burden, if you take into consideration that we take the queries for each table, but a) we add arrays and b) use a less intuitive way to add/remove/delete values to the database. As an example I have give link 1, where the difference was more or less two or three words - and the way to use the arrays where far more complicated to understand then a simple Select Sintax - hence, not that relevant. OOP is about creating reusable code to reduce the maintenance burden, so if you insist that a separate DAO for each individual table is the way to go then you don't understand how to apply the principles of OOP correctly. I will never insist just because some silly reason comes to my mind. I will however not follow a method without knowing the reasons and be convinced of them. I'm not 100% convinced of the reducing benefits for the reasons a) and b) stated above, still, maybe I get more benefits the more I add methods to the DAOs. In the next few days I will try to, based on your code, create a general DAO class that deals with PDO. And post back my frustrations back here. :D Please have patience. :D Regards, Márcio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Otherwise, how would you handle this? Paul Such things can be handled automatically by my generic DAO. Amongst the details which are exported from my data dictionary into each table structure file (which is accessed by the database table class) is a list of all the parent/foreign tables, the foreign key field(s), and which fields to retrieve from the parent table. So when the sql SELECT statement is being constructed it can use this information to add a JOIN to the parent table in order to retrieve the specified field(s). This is documented in http://www.tonymarston.net/php-mysql/data-dictionary.html#sql.joins Any number of parent relations can be defined for a table, and any number of fields can be retrieved from those tables and added to the SELECT list. All the developer has to do is define the relationship in the data dictionary and the framework will handle the boring stuff of generating the necessary SQL. So, using your example, I would define my customer table as a parent to my invoice table, identify which foreign key field relates to which primary key field in the parent table, define customer_name as the field to be retrieved from the customer table, then sit back and watch the framework do its stuff. Each time I read from the invoice table the result would automatically include the customer name. Easy peasy lemon squeezy.

Watch out for this!
You're doing a test that is an assignment..
You are assigning the value .jpg to the variable $file. You are
then comparing this to the value true and (due to the loose variable
types) this succeeds.
Although some people consider it ugly, it is a *very* good practice to
put the constants on the left hand side of the comparison like so:
if (true == (.jpg=$file)) {
I've kept your error above, but if you try and run this code, you will
get a syntax error.
The correct comparison is to do:
if (true == (.jpg==$file)) {
Note the double ='s signs.
As you have VB experiences, this is different, but follows the
conventions of a lot of languages (C, C++, C# etc.). VB inferred whether
you wanted assignment or comparison depending on the context, but this
came at the expense of not being able to nest complex statements.
Of course your example above could probably have been achieved by doing
if (file_exists(.jpg)) {
but that's beside the point :)

Cool @ hosting4days . com

Probably the most similar that allows some wildcards (pattern matching)
is ereg(). You have more power in that you can control what must match
and how much.
In MySQL 'a' = ' a ' is true but 'a' LIKE ' a ' is false. So you need
to use the wildcard % to match anything ' xxaxx ' LIKE '%a%' is true or
_ to match one character ' a ' LIKE '_a_' is true.
The problem with similar_text() is that it gives you a percentage of
similarity which may be misleading unless you also figure in the return
of how many chars match. For example similar_text('CAT', 'CA', $p) $p
would be 66.6%, is that like or not?

Rod [EMAIL PROTECTED] Firstly, if you have a form and you are sending it using GET, then why don't you use a input type='hidden' name='thread' value='yet another new thread' / element to send the parameter - that's what input tags are for. I have a feeling that the ?foo=bar bit is stripped off a GET request URL if there are other form elements, although it's not always stripped off a POST... maybe it's browser-dependent. Secondly, when you refresh the second form, you are making a POST request - that's what generated the form in the first place, so you would expect the message about POSTDATA - and (in Firefox at least), to view the source the browser repeats the page request, effectively the same as refreshing the page. If you want to see the source without repeating the POST request, you need to use something like the WebDeveloper tool bar - it has a View Generated Source function which extracts the source from the DOM model the browser used to render the page. -- Peter Ford phone: 01580 89 Developer fax: 01580 893399 Justcroft International Ltd., Staplehurst, Kent -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Newbie ' If Statement' Question
heredoc is probably the best way to go. There's no way you can mess up your
quotes, and you don't have to worry about escaping. Altough I wonder what
would happen if you put ? in a heredoc, would it stop processing the php,
thinking that it was the end of the php file, or would it just treat it as a
string still?

[PHP] Re: Newbie asks about multi-lingual website strategies
Wow! I love this group, ask and you shall receive. Thanks everyone for the
comments and suggestions.
The following snippet from Andrés Robinet would actually suit my current
project..
define('DEFAULT_LANG_ID', 'en');
function getLanguageId() {
// Allow for language id override in $_GET, $_POST and $_COOKIE
$req_lang_id = $_REQUEST['lang_id'];
// Retrieve the one stored in the session if any
$sess_lang_id = $_SESSION['lang_id'];
// $lang_id will contain the lang id retrieved from request (overrides
session),
// or from session or a default one
$lang_id = isset($req_lang_id) ? $req_lang_id : (isset($sess_lang_id) ?
$sess_lang_id : DEFAULT_LANG_ID);
// Save it for next time
$_SESSION['lang_id'] = $lang_id;
return $lang_id;
}
but the idea of getting a preferred language from the browser is also a
great strategy ( I didnt know you could do that, Im such a noob) so I
think that I will investgate that further.
The problem with IP address is that usually it is not tied to one particular
user so I will scrap that idea.
Am I correct that if two people are logged on using two different languages
that the session var will keep track of the different users (by IP I assume)
and the server wont mess up?
Anyway thanks everyone for all the great help, Im on a nearly vertical
learning curve here and its great to have this community to draw on. Im
pretty much working in a vacuum otherwise.

Sessions are per-user and are not global (you'd need to use something like memcache or similar for global persistence). PHP is different from e.g. ASP/JSP which implement a Share everything system, vs PHP's Share nothing (these are real terms believe it or not!). Sessions usually work via a cookie that PHP set's automatically the is stored for the duration of their visit on your site (till they restart their webbrowser). By default the cookie is called PHPSESSID. If a user has cookies disabled PHP can rewrite your HTML URLs on the fly to include the argument on the GET vars (sess_use_trans_id) but this is far from reliable.

I am doing a website and my client wants the bulk of the text to be

Drawbacks?
2: Cookies again not too big a deal, never used cookies either but it
doesn't seem to be mystifying however the fact that the user can turn
cookies off makes me not want to go this route.
3: Use the mysql database and log each ip address and record the preference
and maybe the last time on the site. I am leaning in this direction because
I think it is the most robust but will it be slow? First I have to get the
ip then I have to check to see if it is in my data base and then get the
language preference. It would be great to have a standardized function that
I could use on all of my sites. I live in a bilingual country (Canada) so
this could be a real selling point for my services.
Any any and all comments are welcome, it will be a learning curve no matter
which route I take so a little advice on the best direction pros cons would
be great.
And of course knowing that I will have many many thousands of people on my
site (hee hee) which option will perform best once I start accumulating
vistors. That's one problem I see with the mysql solution, I think it may
start to be slow unless I start purging vistors who have not shown up in a
while or limit the number of entries.
First of all you can use the browser supplied language preferences (if
available) to try and guess the users preferred language. It should be
obvious from phpinfo() and a half decent browser what vars you need to
inspect ($_SERVER['HTTP_LANG'] or something like that - can't remember
of hand!).
You could do soemthing like:
1. Check session for lang preference and use it.
2. Regardless of the result of 1, check GET for a preference and store
in session if present and use it.
3. If neither 1 nor 2 has any preference, use the browser supplied
preference.
4. If nothing else, use a hard coded default.
OK, that selection taken care of :)
For hard coded strings in your PHP code use Gettext and bind to standard
your catalog files and use the language choice from the above algorithm.
xgettext can extract strings from PHP files easily enough. You just have
to make sure you write in your default language and do not use variable
substition as you normally would in PHP.
e.g.
BAD:
echo gettext(Hello $user, welcome to my site);
GOOD:
printf(gettext(Hello %s, welcome to my site), $user);
printf and sprintf are your friend!!
If you use modules, be sure to write all your strings with a gettext
domain. It's a pain to go back and do this later!!!
I'd recommend looking at the gallery2 codebase for a nice example of
well internationalised and modular string handling.
As for the database contained strings there are multiple approaches here.
You could have a general linking structure that uses tables to store the
different strings. This is simple conceptually but also a pain to
implement in terms of SQL code.
I've actually created a set of custom functions for MySQL (in C) which
pack and extract multilingual content into text fields. It's a bit of a
pain in terms of standards complient SQL but it makes coding much simpler.
I would do e.g. INSERT INTO table (mystring) VALUES(LANG_PACK('en',
'Hello', 'fr', 'Bonjour'));
Then
SELECT LANG_EXTRACT(mystring) FROM table;
(Hello - defaults to first string)
of
SELECT LANG_EXTRACT(mystring, 'de', 'fr') FROM table;
('Bonjour' - can't find de but finds fr).
I've wrapped up the calls to LANG_EXTRACT in the SQL to use the user's
language preference automatically which works quite well.
There are lots of solutions here and if I were to think about it again
I'd maybe reconsider what I've done. It's convenient in some ways but
not so in others!
Hope this gives food for thought.

RE: [PHP] Re: Newbie asks about multi-lingual website strategies
My approach to multi lang abilities uses the following db structure base_name is the input field name and the basic raw label for the field lang_1 lang_2 ... lang_12 prompt_1 prompt_2 ... prompt_12 since i currently need to support 12 languages in the initial concept when the user signs on, i equate the language to an offset on the table to be able to pull the correct language out of the tables. I have the prompts in there to provide prompts for input fields as required. These values are then input thru a translation interface. Using the interface, i build up translatable values for the controls as well, where items like radio buttons and selects are done in the following manner base_name lang_1 lang_2 ... lang_n salutation Salutation Salut something base_name.db_value_1 = first option mr Mister Monsiour base_name.db_value_2 = second option mrs Mrs Madam ... base_name.db_value_n = n option Then for each option value i have a function that pulls the the correct values and builds the options list for each control type Our final step to improve perfomance (note that this is, sadly, ASP / vbscript ) was to take the translation table into an XML application level object to cache the data since its relatively immutable. Now when I write this same app in php, I am more likely to skip the caching portion of this in favor of templating the forms for each language. I would use a folder for each language. hth bastien To: php-general@lists.php.net From: [EMAIL PROTECTED] Date: Tue, 27 Nov 2007 15:18:45 + Subject: [PHP] Re: Newbie asks about multi-lingual website strategies Jeff Benetti wrote: I'm a noob so keep the comments to a noob's level please.I am doing a website and my client wants the bulk of the text to be bilingual (French and English).

That would work, but I think you're probably not approaching the question
properly. Why do you need to redirect the user first, then log the request?
PHP/MySQL are fast enough that logging first and then redirecting will have
no noticeable impact on performance or your user experience. (I'm assuming a
logging process here that's only 1-3 queries.) It sounds like you're trying
to over-optimize, which is always a bad idea as it makes the code harder to
understand later. :-)

Means you're passing the variable as reference.
This means that any change in the variable inside your function will affect
the variable outside your function, in other terms:
if you have
function myfunc($var){
$var = 5;
}
$a = 6;
myfunc($a);
will result in having $a=5 after the function all.

This seems to be a hair faster. I extended the test to 1 requests
(still concurrency 10) to make the test a little more reproducible:
echo str,var,str did 604.65 requests a second where trtd?= $x
?/td/tr did 599.63 requests a second. I also tried echo str . var .
str, and it came in at about 584.55 requests a second. printf(str %i
str,var) came out at 547.01 requests a second and printf(str %s
str,var) was only 452.03 requests a second.
Can you try and time that one so we have comparable results? This one
should be second best:
for ($x=0;$x1000;$x++) {
echo trtdX is $x/td/tr;
}
Approximately 330 (?!) requests a second for that one.
Back again to what would be 'longer', well, in your example, the whole
header, up to the loop itself should be faster if sent out of PHP.
Likewise, you could echo $buffer right after the loop, drop out of PHP
and send the footer as plain HTML. This, of course, is harder to time
since it happens only once. I admit though that I did time the
options I listed and on the 'dropping in and out of PHP' I'm relying
on the PHP manual ( see
http://www.php.net/manual/en/language.basic-syntax.php, the first
paragraph after the examples) and the source of the lexical scanner,
which supports that, though your numbers do contradict it. Interesting.
I'm not sure that my results would count as contradictory - I'm running
APC which would likely throw performance related numbers out of whack as
compared to out-of-the-box PHP.
Because of that, I wouldn't recommend anyone take my numbers too
seriously - they're just an example taken from my server: 1.8 GHz
SMP/1G/RAID5/Linux 2.6.17.7/Apache 2.2.3/PHP 5.1.6/APC 3.0.12p2. Anyone
else's results would probably vary widely.

Doesn't seem to make a difference - I didn't expect it to. I also tried this on my own server. With the opcode cache, the results seem to be the inverse of yours without. I would have been surprised if an opcode cache had made a huge difference. I don't think the Zend Engine is intelligent enough to compile the various different tests to the same set of opcodes - but I could be wrong. I'm still quite new to the PHP internals. Also, with either server, the first three results seem to vary wildly, but the last two always seem to come out the same. I'm not sure why that is...

While the differences on the rightmost column (except for the second one, which is way off) are no more than 5%, in the middle column the differences are up to 10 to 1. But then there is that second row, which is so much higher and it is so in both columns. Unfortunately, I cannot make much sense about all this. I don't get it. Nevertheless, something it is clear is that buffering all the output first and then pushing it out all at once seems to beat them all, specially using single quoted strings.

Then simply echo $report; Actually, in my experience, that is not the case, my e-mail from more than a year ago must be somewhere there in the archives, but what you sugest is not the fastest. The fastest is to escape out of php (with a ? ) for the longer invariable parts of immutable HTML. Stepping out from PHP and in again is handled by the lexical scanner, it doesn't even reach the parser level so, for all effects, the PHP interpreter is basically frozen at the point before the ? was found. For the sake of completeness, the ? is translated as a ; for the parser so it ends any statement that could have been left open, but it does not bother the parser at all for all the rest of the characters found until a ?php tag (or equivalent) is found. If the lexer didn't issue a ; for a ?, the following code would be valid: echo 'This ' , ? is ?php 'not valid'; For the variable parts, the best is to issue as little echos as possible with its arguments separated by commas, not with dots. Most people don't realize that echo taks a list of arguments, a list separated by commas. Thus, in the ratings, from best to worst, it goes: echo 'p' , $something, '/p'; echo p$something/p echo 'p' . $something . '/p'; echo 'p'; echo $something; echo '/p'; The reason for this is that generating a single string either from variable interpolation as in the second case or by concatenating the arguments, as in the third, requires a lot of memory handling for the strings and its intermediate and final results. Some of it might be delayed until the page is served so the time the garbage collector takes to clean it up might not be fully reflected in the processing time of a single page, but it does affect the overall throughput of the server. Notice also that I have used single quotes whenever possible, which is slightly faster since the parser has much less to look for within it. Finally, the first option is the fastest just as a C++ iostream or a Java StringBuffer are faster than plain strings: since you know you will only append to the end of them, the characters echoed go into a much more efficient character buffer instead of a more complex string which has to be available for all sorts of string operations.

In my message I was careful to mention that stepping in and out of PHP was
good 'for the longer invariable parts of immutable HTML'. What could be
considered 'longer' is certainly a matter discussion, your results prove
that this is not long enough. Notice that when the parser finds the '?=',
it converts it into the equivalent of ? echo, thus, though the echo is
not explicitly there, from the parser on is as if it were. Then, since you
have an echo, why not use it for all of the output?The equivalent to
what I showed as the second best, which would be the first best with
'shorter' strings would be the following:
for ($x=0;$x1000;$x++) {
echo ' trtdX is ' , $x , '/td/tr';
}
Can you try and time that one so we have comparable results? This one
should be second best:
for ($x=0;$x1000;$x++) {
echo trtdX is $x/td/tr;
}
Back again to what would be 'longer', well, in your example, the whole
header, up to the loop itself should be faster if sent out of PHP.
Likewise, you could echo $buffer right after the loop, drop out of PHP and
send the footer as plain HTML. This, of course, is harder to time since it
happens only once. I admit though that I did time the options I listed and
on the 'dropping in and out of PHP' I'm relying on the PHP manual ( see
http://www.php.net/manual/en/language.basic-syntax.php, the first paragraph
after the examples) and the source of the lexical scanner, which supports
that, though your numbers do contradict it. Interesting.

I appreciate your reminding me. Because I am new enough that I still find a magical thrill every time I pull *anything* from the database, I have been approaching this from this point of view: 1. Make db 2. Try to get page to connect 3. Try to print what I want by setting the variable $r so I can point to it 4. Fix it so that if someone asks for anything other than an existent ?r=x it kicks back a webpage which just shows links to existing pages.

[PHP] Re: [NEWBIE] How to allow for a href tags but no others?
The solution for this problem (doing it in the matter that you are suggesting) is certainly going to involve preg_replace(). However, this will require you to match only the tags you want to let through (which is always dangerous) and then strip out all of the rest of them. This can be very tricky to say the least. A common way that forums deal with this problem is that rather than letting users create url links they create their own specialized format for letting users create urls. For instance: [url=http://somesite.com/path/to/somepage.php] This way you can still strip out all and characters as well as the text in between them. And now you've limited the problem text to everything inside the pattern [url=*]. You'll still have to look out for MySQL commands, but you've at least limited the problem with tags. -- Teach a man to fish...

[PHP] Re: [NEWBIE] Trying to combine array into one string
while ($tantoData = mysql_fetch_array($tantoResult))

$tantoEmailArray[] = $tantoData;

now all the values are stored into an array ($tantoEmailArray). to convert
an array to a string and join the elements together by a delimiter, use
implode.
hence: implode(,,$tantoEmailArray);
so final email command could be:
mail(implode(,,$tantoEmailArray), $subject, $mailcontent, $addHeaders);

My own code is obviously flawed in syntax in logic, so I searched
the manual and this list's archives under the terms array,
concatenate, convert, append and string in various combinations.
However, while I learned some interesting tips on a variety of topics, I
suspect I'm missing some essential description that will lead me to the
command I need.
The Question:
How do I take the contents of an array and turn them into a single
string?
For Reference:
Here is the code I have. I know it's flawed, but hopefully it will
give an indication of what I'm trying to achieve:
--code--
$tantoQuery = SELECT forum_members.emailAddress AS email FROM
forum_members, event_tanto WHERE forum_members.ID_MEMBER =
event_tanto.tanto AND event_tanto.event =' . $show . ';
$tantoResult = mysql_query($tantoQuery);
while ($tantoData = mysql_fetch_array($tantoResult))
{
$tantoEmail = $tantoEmail . , . $tantoData;
}
mail($tantoEmail, $subject, $mailcontent, $addHeaders);
--code--
Any help would be much appreciated.

That way, if any of us see a question that we KNOW is answered in FAQ or php.net/xyz and that is not a Reply of some kind, we can let the robot handle it. What do you think? Worth doing? Waste of time? You interested in implementing or testing it? Got a server where you control smrsh and whatnot enough to handle it? [/snip] I like it a lot. And I would be glad to put in my 0.02.

[snip] I'm not going to promise any of this. If someone else is willing to donate the hardware to make this happen then contact me / the list. Of course anyone else that wants to donate coding time is more than welcome to join project ParrotHeadPoster. :) I can already imagine it now... I'm a talking phParrot and I think I can help you. Try reading what you find at the following link(s): [/snip] Cool, a ParrotHead reference and name for the project in one post.

...lots of really good stuff...

So, basically I saw 3 possible action items from this discussion...
1. phParrot development
2. Weekly CRON of NEWBIE GUIDE (once I get the e-mail portion figured
out)
3. OT posts should contain a TIP or TRICK? If we did this we could
harvest them once in a while for dissemination to the group. How you
say? You could contain the tip in a tag, example...
[tip type=query error checking author=Jay Blanchard]
When issueing a query to the database I always find it healthy to do
error checking in this form
if(!($resultOfQuery = mysql_query($query, $databaseConnection))){
echo This gave me an error . mysql_error() . \n;
exit();
}
If an error is thrown the application exits immediately so that I can
correct and move on.
[/tip]
As you can see, using some reasonable regex would get the tip out. Also,
when phParrot is up and running a tip can be given with each reply if a
databse of these tips was gathered. Someone then could gather all of the
tips, publish a book and make us all famous.
I may have had too much caffeine this AM -- looks like my enthusiasm
level is set to 'HIGH'

As we are developing a knowledge base for our internal users and this falls along the same lines I would have to say to count me in. I like the sound of it too. shall we crystalize what we want/decided into a new post? 1. what we want: i.e. repository of list tips/solutions etc 2. a parrot 3. where to host 4. who/where to run the parrot 5. any other business Jay maybe your the man for that job? not trying to force anything on you but I reckon we could do with a 'lead man' of some sorts to do a little coordinating and possibly just make a decision (avoid endless discusion about minutae) Also I may have a machine capable of running the parrot - its on the same subnet as nl2.php.net so connection speed is no probs but I have no idea how process intensive the parrot would be (if its too heavy I would have to decline cos there are commercial site running on the same box which expect a certain level of performance :-) ...paying customers, you get the picture!).

4. a website/subsite related DB to store data for phParrot, tips, etc.
phparrot.net is up for grabs - I'm happy to register it (can't grace the list
with
ace mathematical explainations :-) but I'm happy to shell out a few bucks as a
way
of giving back a little) - and I'd just as happily transfer the domain into the
hands
of an 'official' php organisation if and when people think its required (at no
charge).
or maybe someone else want to register it?
also nobody seems to dare speak up regarding a 'front man'?
