RE: [PHP] Radio buttons problem
Why do you? There's no reason you *have* to have consecutive indexes -- just iterate over the resulting array with foreach, and there's no problem. There is, the entries are grouped by its index. So, I group name[0], email[0], and sex[0] as one. The problem if I don't maintain the index for radio buttons, the index could go wrong. In the previous example I gave, if entry2 is deleted (and I don't maintain the index) then entry3 will contain name[1], email[1], and sex[2] which isn't desirable. -- View this message in context: http://www.nabble.com/Radio-buttons-problem-tp24786766p24897287.html Sent from the PHP - General mailing list archive at Nabble.com. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Very interesting. Excellent debugging advice. It's giving me a 500 error, probably why the Rackspace techs told me to check my code: HTTP/1.0 500 Internal Server Error Date: Sat, 08 Aug 2009 00:01:10 GMT Server: Apache/2.0.52 (Red Hat) X-Powered-By: PHP/5.2.10 Content-Disposition: attachment; filename=Installer.bin Content-Length: 23223296 Connection: close Content-Type: application/octet-stream I'm at a loss. Nothing changed in the code and it works for ZIP files. I notice the X-Powered-By header shows you are running on PHP 5.2.10. This was released on 18-June-2009, so Rackspace must have upgraded your PHP installation some time after that. I think it's a reasonable assumption that something is behaving differently in PHP 5.2.10 from how it did in whatever version you were running under before. You need to track down what that something is, and fix it! Cheers!

Something like:

verse_of_the_day_activate, ...))) {
should work.

Put all the compared values into an array, then check that $page is not

[PHP] Is there any considerations for not putting php scripts in tmpfs?
Hi php-general, sorry if it is a wrong lists for this question. I have read many articles/messages about using tmpfs store temp files, for example, php session data, smarty compied templates and so on. An obvious reason for that is: it doesn't matter about data loss caused by machine restart/poweroff. since it is not that difficult to restore files on a tmpfs from a disk-based dir when machine boot up. so may i put all my php scripts on a tmpfs to speed it up? would that cause other issues? thanks for your advices.

Thought I tried that. Apparently not exactly; it works now! Thanks. I
know it is clunky but I wanted to see how compact it could be done.
If you switch it around you'll get a notice because the IF evaluates
from left to right. So you just want to make sure you check isset() first.
This would throw a notice:

solution?

Two reasons:

I would have thought both would have to be true on their own (without
notice) in order for the the combined expression to be true (without
notice). But Shawn pointed out that the order matters; if we check
for the var's value before checking if it isset then we get a notice,
but if the order is reversed, then we get no notice.

That's logically correct, and while PHP does implement this
short-circuit logic, not all languages do. In that regard, I
appreciate what John meant by saying it makes it look more
intelligent. Some languages evaluate each of the conditions to their
respective boolean results before evaluating the logical operators.

This intelligence is given by the laziness of the operator.
$res = a() b(); # if a() is false then b() does not evaluate
$res = a() b(); # b() evaluates no matter a()'s result
so, order matters.

AW: [PHP] reason for a Notice:.. on one site but not another? (Same code.)
the single is a logical AND so a() NOR b() is evaluatet ! its usually used on
binary integer.
e.g. 0x0001 0x0001 = 0x0001 equlals TRUE while 0x0002 0x0001 equals FALSE
so something like $a $b guides to some very interisting results depending of
their values
but nothing u expect.
while tells 'evaluate' the expressions on both sites and combine its results
in an AND operation.
thats why compilers and interpreters do have a definition what value TRUE has.
its very likely that TRUE is 1 and false is 0
lets say
$a = 1
$b = 1
then
$a $b is 1 or true and it would give the same like
$a $b in that case
at that point its also to mention that an empty string in PHP is NOT == FALSE
this gives the following result on an empty string:
$a = ;
isset( $a ) == TRUE
while
$a = null;
isset( $a ) == FALSE;
for the same story there are the
==
===
and
!=
!===
operators

This intelligence is given by the laziness of the operator.
$res = a() b(); # if a() is false then b() does not evaluate
$res = a() b(); # b() evaluates no matter a()'s result
so, order matters.

That's logically correct, and while PHP does implement this
short-circuit logic, not all languages do. In that regard, I
appreciate what John meant by saying it makes it look more
intelligent. Some languages evaluate each of the conditions to their
respective boolean results before evaluating the logical operators.

Gmail automatically sent my last email, apologies.
I am creating an order form for tickets for a list of performances at a
performing arts center.
Currently, the form is on paper, and is set up as follows:
-Title - date - time - price - soldout - quantity - total($)
-Nutcracker - Tues 10/13 - 9am - $4.00 - yes/no - - __
-Nutcracker - Tues 10/13 - 11am - $4.00 - yes/no - - __
-Mayhem P.. - Thur 01/21 - 9am - $4.00 - yes/no - - __
-Mayhem P.. - Thur 01/21 - 11am - $4.00 - yes/no - - __
-Max and... - Tues 04/21 - 9am - $4.00 - yes/no - - __
A given show may have between 1 and 4 performances, and I figured the best
way to approach this was to consider each show time for each show as an
entity. There are 19 unique titles, but given different showtimes, it
becomes 38 'shows'.
I have the shows in an array ($shows), and the details for each show in its
own array (eg. $show_01) embedded into the show array.
I need to generate a row for each show (so 38 rows), and assign quantity and
total input fields a unique name and id.
I can't seem to get my foreach loops to work, will PHP parse embedded loops?
Here is an example of my embedded arrays:
[code=shows.php]
$shows = array();
$shows['show_01'] = $show_01;
$show_01 = array();
$show_01['title'] = 'Van Cliburn Gold Medal Winner';
$show_01['date'] = 'Tues. 10/13/2009';
$show_01['time'] = '11am';
$show_01['price'] = 4.00;
$show_01['soldout'] = 0; //IF THE SHOW SELLS OUT, CHANGE 0 to 1
(without quotations).
$shows['show_02'] = $show_02;
$show_02 = array();
$show_02['title'] = 'Jack and the Beanstalk';
$show_02['date'] = 'Fri. 10/23/2009';
$show_02['time'] = '11am';
$show_02['price'] = 4.00;
$show_02['soldout'] = 0; //IF THE SHOW SELLS OUT, CHANGE 0 to 1
(without quotations).
[/code]
And here are the foreach loops I'm trying to build the rows with:
[code=order.php]
?php
foreach ($shows as $key = $value) {
foreach ($value as $key2 = $value2) {
print ' td bgcolor=#DD'. $value2 .'/td';
}
print 'trtd';
print ' td colspan=3 bgcolor=#DDinput
name='.$value.'_qty type=text id='.$value.'_qty size=5 //td';
print ' th bgcolor=#DDspan class=style6$/span';
print ' input name='.$value.'_total type=text
id='.$value.'_total size=15 maxlength=6 //th';
print ' th bgcolor=#DD class=instructyes/no/th';
print '/tr';
}
?
[/code]
In case you were wondering why I embedded the foreach statement, I need each
array (eg. $show_22) to display in a row, and I need PHP to build as many
rows are there are shows.
Is this something I need to have in a database to work?
Thanks!
Embedded loops are OK, actually I don't know a language where you can't do it :)
I think that your problem is the $shows array creation, you do this:
$shows = array();
$shows['show_01'] = $show_01;
$show_01 = array();
Note that you are assigning $show_01 to a key in $shows before
creating $show_01, you should first create and fill $show_01 and then
assign it to a key in $shows.
Hope that helps.

John,
I did this, and got my arrays dumped (on one line). After adding line
returns, here is a snippet:
[code=array dump]
array(38) {
[show_01]= array(5) {
[title]= string(29) Van Cliburn Gold Medal Winner
[date]= string(16) Tues. 10/13/2009
[time]= string(4) 11am
[price]= float(4)
[soldout]= int(0)
}
[show_02]= array(5) {
[title]= string(22) Jack and the Beanstalk
[date]= string(15) Fri. 10/23/2009
[time]= string(4) 11am
[price]= float(4)

[/code]
and for reference, my original php used to set up arrays
[code=shows.php]
$shows = array();
$show_01 = array();
$show_01['title'] = 'Van Cliburn Gold Medal Winner';
$show_01['date'] = 'Tues. 10/13/2009';

You can do this...
for( $b=true; your-statement; $b = !$b )
{
your-code
}
I usually use this solution
$types = array( 'one', 'two' );
foreach( $list as $item ) # -- your set of (many) items
{
echo current( $types ); # -- this prints the current class
# code
next( $types ) or reset( $types ); # and this do the magic
}
Hey! look, this solution can work with more than 2 types...
try it with many types: $types = array( 'one', 'two', three', 'four' );

In the PHP code snippet you pasted above, you're using single-quotes to delimit your literal strings. In-between single-quotes, '\n' is not converted to a newline character. It's interpeted completely literally: http://us.php.net/manual/en/language.types.string.php#language.types.string.syntax.single Also, are you looking to insert a line break into the HTML itself -- just to keep your HTML code clean -- or into the visible page that's rendered from the HTML? Because newlines don't have any significance in HTML. You'd need to insert a br / or close a block-level element to get the effect of a line-break in the visible page.

On Mon, Aug 10, 2009 at 4:58 PM, Daevid Vincent dae...@daevid.com wrote: From: Robert Cummings [mailto:rob...@interjinn.com] However, accelerators don't make scripts faster per se. They merely cut out the script reading and parsing time. Which is a HUGE portion of time since PHP is a two-pass step. One that reads and compiles to opcodes (with syntax checking) and another which actually executes it. obviously, this is sensitive to the amount of code being run in a single request. the more code, the more parsing / compile time. but even that has no bearing on how long the code of the script will run (as rob said). if youre dependent on remote resources, eg a database or other network requests, like soap or rest to other remote servers, those are the sorts of things that generally dominate the time spent handling a request. even for scripts run through the webserver, an opcode cache is a secondary performance booster, where optimizing things like database performance will usually drawf the returns a site gets from apc. that being said, you obviously want all the juice you can get, so running apc aside a tuned database is ideal :) So, while you may experience 10% gain within the first second of your script running, the use of an accelerator should have no bearing down the road except for the initial dynamic load of other scripts at runtime. This is sort of misleading. You will experience faster page loads if it's a web php file, and if APC does allow you to run cached scripts via CLI, then these scripts will start execution immediately too. right, but from what ive seen the php environment is not persistent on the cli like it is inside a webserver. therefore, when the second request comes in, apc will have to re-cache all of the scripts it cached the first time. afiak anyway. if there is persistence in cli php, then how would one clear out the cache for the cli based scripts?? apc gives you no tools to accomplish this that im aware of, and theres no way you could do it from a webserver either, since im pretty sure, cached scripts, just like apc 'user' variables are only visible w/in a single domain (def correct me on that part if im off base, i know eaccelerator handles things that way) Long running scripts will see almost no benefit from an accelerator. PHP scripts are (like it or not) NOT designed to be daemons and run for long periods of time. def not inside of the webserver, but on the cli i see no reason why php cant be long running - and good at it. you just have to like actually start cleaning up old variables, lol. so while its not as forgiving as the webserver php environment, i doubt there are any real reasons to stay away from a long running php cli app except performance vs. alternatives. The GC is no optimized for such things. It's quite inneficient from what I've read. The whole purpose of a PHP _page_ is to get in and get out. Hit it and quit it. Therefore memory efficiency is not as important as speed and ease of use. This is the general reason why CLI acceleration isn't very useful. That said though, one could certainly glean an advantage if they had a cron job or other daemon that was loading a script often. As is probably often the case, moreso than a long running script. I think a code optimizer is what would be desired if you're trying to make a faster script. However in this day and age, I suspect that the 2nd phase of the compiler already does all the optimizing it can before creating the byte code. im guessing the optimization inside of apc is currently pretty weak, since eacellerator has been the system most popular for optimization thus far, and since apc is adding optimization as a future component of the project, officially, which is still in alpha. http://pecl.php.net/package-info.php?package=optimizerversion=0.1alpha1 -nathan

RE: [PHP] how to say inverse your value (to a boolean)?
Then YOU have more aggressive error_reporting than the default setting
turned on. You might consider turning it down a notch. NOTICEs are basically
useless and bloat your code IMHO -- and apparently the PHP devs too as per
this...
http://us2.php.net/manual/en/function.error-reporting.php
// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);
Don't tell me what to do! You're not my father! ;-)

Some people, when confronted with a problem, think 'I know, I'll use XML.'
Now they have two problems.

Use...
$dr = !$dr
if you want
Notice: Undefined variable: dr
All variables MUST be initialized before using.
If you PHP does not complains about it you should read about
error_reporting

Just do this. It's quick and simple:
CSS:
.dataRow1 { background-color: #DFDFDF; }
.dataRow2 { background-color: #FF; }
foreach ($foo_array as $foo) {
?tr class=?= ($dr = !$dr) ? dataRow1 : dataRow2
?td?= $foo
?/td/tr?php
}
No need to initialize $dr as by default PHP will make it a
boolean false,
then each itteration, it will toggle true/false and
substitute the CSS
class

[PHP] Sending email w/ attachments
Hey all,
Trying to send emails with attachments, first try at this. And
am trying to adapt sample code I found here:
http://www.webcheatsheet.com/PHP/send_email_text_html_attachment.php
Trying this:
($data contains the contents of the file; I've verified this)
$hash = md5(date('r', time()));
$attachment = chunk_split(base64_encode($data));
$body_attachment = --PHP-mixed-$hash--\n .
Content-Type: application/octet-stream; name=\$filename\\r\n .
Content-Transfer-Encoding: base64\n .
Content-Disposition: attachment\n.
$attachment . \n .
--PHP-mixed-$hash--\n;
I then append $attachment this to the end of the email body
and send it on. I've verified it is reading the file properly,
in this test case it is a place text file. But I've tried a
PDF and that did not work as well.
What happens is the email comes through and shows an
attachment paper clip icon in Thunderbird, but when the email
is clicked on the icon disappears and the email is empty, even
the body is not there and no attachment either.
A final question I have is does the content-type value need to
change for text files, Word Docs, PDFs, Excel files, etc, or
is there one type that can handle any file type?
Any help would be great. I'm rather stuck and floundering here.
Thanks,
Skip

RE: [PHP] Re: how to say inverse your value (to a boolean)?
Pretty much the best operator ever invented IMHO. And Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise. Awesome! Also, Adam Randall set up us the bomb. ;-) (http://www.youtube.com/watch?v=qItugh-fFgg) -Original Message- From: Adam Randall [mailto:randa...@gmail.com] Sent: Monday, August 10, 2009 6:41 PM To: php-general@lists.php.net Subject: Re: [PHP] Re: how to say inverse your value (to a boolean)? http://us3.php.net/manual/en/language.operators.comparison.php Find Ternary on that page.

No...not zerowing...no... But yes, the ternary operator is the bomb, which you can get carried away with. Daevid knows what I mean :) Adam.

Re: [PHP] Sending email w/ attachments
Funny, I just had to figure out today how to nicely do HTML e-mails. I
ended up using PEAR:Mail_mime, and it worked pretty well. It will also
work for your attachments. I believe that PHP itself recommends it on
their mail() function reference page.

Wow, were to start with all the problems in the above code:
1. Short tags?
2. Not using echo or print. You actually recommend breaking in/out of php?
3. Using uninitialized variables (I run with the E_ALL crowd)
4. Using the tr class='' and not the td class=''... Hmmm
}
No need to initialize $dr as by default PHP will make it a boolean false,
then each itteration, it will toggle true/false and substitute the CSS class
