I think, but i am not quite sure, that this can be done with AJAX. Also some Java-Applets are able to do stuff like that. It will still be tough since you have to tell your browser somehow that he has to reload the image. Not quite easy.

[PHP] Problems with Arrays and print and echo
Slowly I am getting the output I want.
Trying to use dynamic arrays, does creat the array I want, but getting
the info is sometimes surprising.
I notice a difference between arrays used locally in a function, and
arrays used as a 'var' in a class function (all in PHP 4 atm).
Code snippet:
echo ROWS returned are: $max\n;
$this-count = $max;
while ($max--) {
$row = mysql_fetch_row($result);
$this-name[$max] = sprintf(%s, $row[0]);
$Name[$max] = sprintf(%s, $row[0]);
echo init \$this-Xame[$max] = $row[0];
echo $Name[$max] $this-name[$max]\n;
$regionID[$max] = $row[1];
$constellationID[$max] = $row[2];
$this-ID[$max] = $row[3];
printf(%d:%d/%d/%s\n,$max,$regionID[$max],$constellationID[$max],
$this-name[$max]);
}
Line wrap is messing things up a bit.
Was trying sprintf to see if the was a buffer problem coming from mysql.
Problem seems to be the same, regardless.
Also, the names changes ($this-name[] versus $Name[]) are deliberate,
for just in case
Output (debuging):
ROWS returned are: 7
init $this-Xame[6] = 8-TFDX 8-TFDX Array[6]
6:1003/2044/8-TFDX
init $this-Xame[5] = B-E3KQ B-E3KQ Array[5]
5:1003/2044/B-E3KQ
init $this-Xame[4] = BR-6XP BR-6XP Array[4]
4:1003/2044/BR-6XP
init $this-Xame[3] = G5ED-Y G5ED-Y Array[3]
3:1003/2044/G5ED-Y
init $this-Xame[2] = O-LR1H O-LR1H Array[2]
2:1003/2044/O-LR1H
init $this-Xame[1] = UL-4ZW UL-4ZW Array[1]
1:1003/2044/UL-4ZW
init $this-Xame[0] = Y5J-EU Y5J-EU Array[0]
0:1003/2044/Y5J-EU
++
Thanks for your ideas, help, etc..
Maybe it is somethign as simple as can't do that with echo, but when
the arrays are all single element ( foo_array[0] is only element ) all
statements work as expected.

[PHP] make global variables accessible to functions?
Hello,
We use PHP 4.3.9. 'register_globals = Off' is set in php.ini. I've heard
using 'global' could cause security problems. Is using $GLOBALS still not
more secure than using the 'global' keyword? How should function foo()
obtain the value of $a?
?php
$a = 'one';
foo();
function foo () {
global $a;
echo a is $a;
}
?

That way is secure and has nothing to do with register_globals ;)
What you can do too is this:

Re: [PHP] IF or SWITCH (asinine?)
Ray said: I'm pretty sure he's ONLY talking about IF/ELSEIF and not IF in general. That's what I got from the message. Correct me if I'm wrong. Of course, you're absolutely right -- I said specifically IF/ELSEIF. My objection is not with the IF statement, of course I use that. In fact, I use if/else for two choices and switch for three or more. I find it interesting that some programmers, who have to be exact with their syntax, can't read a simple statement containing proper syntax without misreading it. --- John C. Nichel IV said: I remember IF constructs from BASIC and PASCAL, but no switch statements (somebody correct me if I'm wrong). But what I'm wondering is how in the world did you do conditional checking if there were no switches, and you don't use IF's? Did you not code error handling, different cases based on user input, status of a data stream, etc in all the years prior to something like switch being introduced??? I'm no programming historian, but from memory, Fortran, BASIC, and PASCAL all started without a switch construct. However, later-on BASIC most definitely provided a SELECT/CASE and PASCAL had a case operation of some type -- as for FORTRAN, it's been a long time since I did anything in it, I don't know. As for how did I did conditional checking, I did it like every other programmer of that day -- and without ELSE/IF's. You certainly can't use the construct if it's not there -- using IF's sufficed and as I said above, I NEVER said that I don't use if/else -- what I said was I don't use if/elseif. Actually, by you misreading my post, you provided support for my claim that the use of if/elseif is confusing and thus less readable. Clearly if I had said that I don't use the switch, there would have been less confusion on your part, right? --- Rob said: I think I may have read too much into your previous post. Are you saying specifically that you never use the elseif construct or any of the if, elseif, else constructs? If the latter then I think your methodology is somewhat asinine since I'm sure 99% of the programmers out there would view code consisting entirely of switches in place of ifs with a huge grain of WTF :) You read too much? No, the case is that you didn't read enough -- or you didn't comprehend what I wrote. I said that I NEVER use the IF/ELSEIF construct. I did not say that I don't use IF/ELSE (forgive my double negative). Don't be what you called my methodology. As for what the 99% of programmers out there -- Locus ab auctoritate est infirmissimus. Also would you care to provide proof for your statistics? --- Kevin provided: benchmarks can be hazardous, but lets look at them at their most basic level. By this I mean how folks use them every day... http://www.phpro.org/benchmarks/if-switch-benchmark.html Thanks for the link. That fits with my tests -- however, the speed difference, which in not significant IMO, is not at issue with me -- it's the readability. To me, the switch wins hands down in readability over the multiple if/elseif's. However, I realize that's a personal decision and do not claim good/bad practice in using either. --- M said: If it can be used, I'd go for the clarity of switch. I have yet to find a single problem where a switch can't be used to replace multiple if/elseif's. I even posted an open query to this list in that regard, and while at least one was compelled to call my methodology asinine, no one could provide an example otherwise. So my claim stands that you simply don't need the if/elseif construct -- for it can be totally replaced with the switch. Now, someone prove me wrong -- please -- I would like to know why the construct is still around after being the evolutionary step between if/else and switch. Is it just habit, or what? Personally, as I said before, I use if/else for two conditions and switch for three or more. Your mileage may vary, but it's truly a matter of choice and is not one of asinine methodology.

However, I've been asked to look in the possibility of the teams completing the form offline, and uploading when they have access to a connection. It looks like I might be able offer something like Microsoft InfoPath forms (better recommendations?) to generate an XML file, and then use a PHP file to upload the file into the database. Additionally, I could also do with this process uploading a number of other files (e.g. images, text files) to the server.

Anyone else have any experience with something like this, or any other helpful suggestions for making the page load time a little less cumbersome? Brad, If the data and the application permit, you can split the list into a series of nested lists and let the user drill down to the desired item. (If it's a multiple-selection menu, this could get tricky.) If the user can select from one or more category menus to get to the finest granularity of detail, they will have multiple steps to perform but the wait-time on each step will be far less than downloading a 12,000-option list, and therefore the user's perception of wait-time will be less. There are serious usability issues with very long lists -- for example, the scrollbar button on the list control can become so small that it's difficult to grab, and paging down a few hundred times isn't fun. You can help ameliorate this by ordering the options alphabetically so the user can at least jump to the desired initial letter. Even so, 12,000 / 26 is still 461, a huge number of options to have to scroll through. Here's one example of a drill-down in which all the category menus remain on the screen: http://www.dandemutande.org/ResourceGuide/ Paul -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You may want to use this forms generation class that comes with a linked select input plug-in . You can link an unlimited number of select inputs making one show a sub-set of the options depending on the value selected in the previous select. The good part is that it can retrieve the options of each select from static arrays or dynamically a database via AJAX. This means that when you change the value of one select the new set of options of the dependent select are loaded without page refresh. Despite it can use AJAX, you do not have to learn a single line of Javascript. All is achieved with PHP code. The plug-in takes care of any Javascript generation. It supports MySQL databases directly or any other database using Metabase or PEAR::MDB2 API. Here is a live example of the static array mode. http://www.phpclasses.org/browse/view/html/file/9879/name/test_linked_select_page.html There are examples of the dynamic mode in the class page. http://www.phpclasses.org/formsgeneration -- Regards, Manuel Lemos Metastorage - Data object relational mapping layer generator http://www.metastorage.net/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Completing forms offline with PHP/MySQL
If your users are using Windows, then something like http://www.hypervisual.com/winbinder/ might be good on the user side, as you can bundle the PHP binary and everything else needed into one executable (with some work of course) And then they can create a file formatted to your specifications to upload sometime later. Or you can use some other UI like QT to create the XML document on the client side which would be cross-platform. The only way to re-use what you have in an offline web environment would be like Jay said to install the required software on the client's / user's computers, and is that really something that is maintainable? The key question: is the additional work required really beneficial?

I was assuming that you meant that the string Hello $foo --
including the dollar sign -- came from the database.
If $foo exists as a native PHP variable, I'd want to see your actual
code to tell why it's not being properly evaluated by the parser.
Sometimes you need to use curly braces to help the PHP interpreter
differentiate a variable from the surrounding text:
$bar = Hello ${foo}amaran;
If you escape the dollar sign, the variable won't be evaluated:
$bar = Hello \$foo;
RESULT: Hello $foo

Re: [PHP] Re: make global variables accessible to functions?
Thanks for the response.
That way is secure and has nothing to do with register_globals ;)
Good. That's what I wanted to hear. I know by default some pre-defined
global variables can be accessed through $GLOBALS. If I don't want end
users to add their own user defined variables in the superglobal area, how
should I do that?
What you can do too is this:
?php
function foo($a) {
echo a is $a;
}
?
Yeah, I know it works this way. The reason I don't go this way is I have
quite a few variables that need to be passed to the function, it's not
feasible to pass all them as funtion parameters.

Re: [PHP] microtime questions
Tedd, The only way that I can even think of this as being possible is if you call microtime() instead of microtime(true). The former will return 'msec sec' separated by a space which can produce a negative number because you've essentially got two different types of measurements there. IMHO PHP should probably throw out an error when two strings are used in a mathematical way - in this case (without the TRUE arg) here is a possible equation that could be evaluated. 0.15290800 1144430717 - 0.86641600 1144430716 PHP evaluates this to -0.713508 (or 0.15290800 - 0.86641600) It's negative because we're not talking about msecs from the same second - it ignores the seconds and only pays attention to the microseconds. So if you're using microtime(true) how can this happen on your machine? Well, off the top of my head I think you should verify that your machine (or your hosting service) is running PHP5 || . IF not, and error reporting is turned off, then you'll get a negative number from time to time since the seconds are being ignored. http://php.net/microtime has an example of how to emulate microtime(true) on PHP 5 Hope that helps! -Joe On 4/7/06, Brad Bonkoski [EMAIL PROTECTED] wrote: How is the CPU not in question?

Re: [PHP] how to run 'periodic'
Frank, It sounds like you need to run this as a job through crond. I'm not sure what the OSX version is (maybe they have a port of crond?) but you could set that up to execute the specific code, as root, whenever you want. As far as I can think, and maybe Chris Shifflet can confirm/deny this, you shouldn't be running into any additional security issues by executing the script as root - As long as it's running through the CLI version of PHP. Just make sure it's only executable by root and then root should be the only one allowed to create that mammoth ;-) - Joe On 4/6/06, Frank Arensmeier [EMAIL PROTECTED] wrote: Hi.

That's what I was thinking. Even if data is a number, I still generally put
quotes around it to make sure I don't have an issue.

Re: [PHP] Parse Error on SQL Insert
Mi vote goes to the curly braces
The error is given by php, not by SQL
When exploding variables within double quotes it is hard for php to
distinguish when a variable end unless it is a simple variable like $foo.
When it is an array element and even worst, when it is an element of a
multidimensional array, php cannot assert when it is over (really, it is
not a bug, try to figure out how to do it and you'll see it is not easy) so
you tell php by enclosing the whole variable in curly braces.
Which it says so in the manual

Let's say we have 10 parts ordered, if we split that amongst vendors, even paying a higher shipping cost in some cases can be cheaper. We can send 2 of those parts from this vendor and 3 from another and so on. We have an ID, price, ship price and vendor to consider that is retrieved via the api with each vendor.

[PHP] Re: Parsing variables within string variables
Thanks for all these responses, but unless I'm missing something none of them work for what I need. Quotes are irrelevant: with the string Hello $foo in $bar echo $bar echo $bar both produce Hello $foo and echo '$bar' produces $bar I can't use any of the answers like 'Hello'.$foo because I have to parse the string 'Hello $foo' as it comes from the database: I don't get to construct it. I did hold out more hope for the eval function, but it seems to me that this is for PHP code in a database, not to evaluate variables. If anyone else can provide the silver bullet, I will be very grateful. David.

Re: [PHP] Parsing variables within string variables
Dear Paul,
this is exactly the problem: the string including the dollar sign comes
from the database.
The problem I have is that the echo statement parses the $bar reference,
but not the $foo reference within it.
So
echo $bar
generates
Hello $foo
which is better than
$bar
but doesn't get as far as
Hello cat
What I think I need is to send the results of the first echo to a second
echo for parsing. Is there some way of doing that?
Thanks for any help...
David.

I was assuming that you meant that the string Hello $foo --
including the dollar sign -- came from the database.
If $foo exists as a native PHP variable, I'd want to see your actual
code to tell why it's not being properly evaluated by the parser.
Sometimes you need to use curly braces to help the PHP interpreter
differentiate a variable from the surrounding text:
$bar = Hello ${foo}amaran;
If you escape the dollar sign, the variable won't be evaluated:
$bar = Hello \$foo;
RESULT: Hello $foo

I did hold out more hope for the eval function, but it seems to me that this is for PHP code in a database, not to evaluate variables. David, please try the eval() route: it will do what you want. You say, this is for PHP code in a database, not to evaluate variables, but evaluating variables is absolutely part of PHP code processing! Eval() will operate on $x = 4; just as easily as on Hello $foo. You should not use eval() frivolously because it presents a potential vulnerability in your code. You may wish to ensure that the database text it operates on is first cleansed of any other PHP syntax -- similarly to the way we should all ensure that any incoming data is clean before we process it and incorporate it into our scripts. Here's an example of variaible evaluation: ___ $bar = cat; $foo = Hello \$bar.; echo $foo; RESULT: Hello $bar. By escaping the $, I have made it a literal character in the text, the same as if I'd read Hello $bar from a database. ___ eval(echo \$foo\;); RESULT: Hello cat. This is equivalent to scripting: echo $foo; I'm using eval() to execute the echo command and interpret the PHP variable $foo. ___ eval(\$dog = \$bar;); echo dog = . $dog; RESULT: dog = cat Here I'm using eval() to set one PHP variable equal to another. ___ You can't simply write: eval(\$bar;); or $x = eval($foo); because everything inside the eval() parentheses needs to be a complete PHP statement. The eval() function itself doesn't return the value of an evaluated expression. To capture the value of an expression, you must evaluate a complete statement that sets a variable equal to the expression as above. ___ Clear as mud?

Chris:
As I am sure you know, passing by reference is simply passing the
memory address of the variable to a function instead of it's value.
If the receiving function does something to the variable at that
address, then the value at that address is changed. You can test this
by simply checking the value before and after it's returned from the
function.
For example, the following just passes the memory address of variable
$a to a function. After which, the function alters the variable at
that memory address, but doe not return a value. But, echoing the
variable after the function call shows that the variable has indeed
been altered.
?php
$a = 10;
echo($a br/);
ref($a);
echo($a);
?
?php
function ref($a)
{
$a--;
}

Re: [PHP] IF or SWITCH (asinine?)
Personally, as I said before, I use if/else for two conditions and
switch for three or more. Your mileage may vary, but it's truly a
matter of choice and is not one of asinine methodology.
tedd
I think that's a fairly good methodology to follow. I usually do that...
except when I run into a huge list of multiple conditions for each
possibility (TRUE FALSE OR FALSE TRUE) etc. To me IF/ELSEIF is easier
to ready in that case,
The true false scenarios require me to work up a truth table, for
I have great difficulty figuring that out in my head.
and SWITCH is a LOT easier to read if you have one
variable and have a CASE for each possibility of that variable.
I believe (until someone informs me otherwise) that your statement
above is a common misconception of the switch conditional -- you
don't need a single variable to evaluate. Case in point, try this
(taken from your own code).
$who_cares = 1;
switch ($who_cares)
{
case $numFFELP 1 count($FFELP_Lenders) 1 $numFFELP == $numTotal:
$retVal = array(TRUE, 'A');
break;
case $numFFELP 0 $enumFFELP 0 count($FFELP_Lenders) 1
$enumFFELP + $numFFELP == $numTotal:
$retVal = array(TRUE, 'A');
break;
}
Note, it's not actually required to have a variable to be evaluated
for each case statement. Each case statement stands on it's own
independent from the evaluation.
This has always worked for me in other languages and I am assuming
that it works the same in php.
Does anyone disagree or will correct me?
HTH's.

Good. That's what I wanted to hear. I know by default some pre-defined

should I do that?
What you can do too is this:

Yeah, I know it works this way. The reason I don't go this way is I have
quite a few variables that need to be passed to the function, it's not
feasible to pass all them as funtion parameters.

Some SMTP servers are attached to MTA, so they can receive messages to be resent to their final recipients. PHP under Unix/Linux calls the sendmail program. Every Unix/Linux MTA emulates sendmail, including exim. The sendmail program just attempts to resend the message or queue it for later delivery attempt.
