Only PHP is treating the hyphen as a minus sign --- which in turn is
causing a syntax error.
How do I retrieve the value of this variable and over come the “minus”
sign that is really a hyphen?
php ${distributor-42-2} = 5;

I'd just try and avoid the hyphens in the variable names in the first
place if you can. Can you guarantee that everyone working on this system
will know when to encapsulate the variables in braces?

Agreed.
From http://www.php.net/manual/en/language.variables.basics.php :
Variable names follow the same rules as other labels in PHP. A
valid variable name starts with a letter or underscore, followed
by any number of letters, numbers, or underscores.
The ${var} circumvents this (somewhat), but in the case above, it
would be better to avoid the dashes and use underscores.

You can add this to apache conf:
FilesMatch ^phpscript$
ForceType application/x-httpd-php
/FilesMatch
Then make a file called phpscript without extension and drop it in the
web root.
?php
$info = explode('/', $_SERVER['PATH_INFO']);
Then your url would look like:
http://server.domain.com/phpscript/variable1/variable2

Performance: http://httpd.apache.org/docs/current/howto/htaccess.html You should avoid using .htaccess files completely if you have access to httpd main server config file. Using .htaccess files slows down your Apache http server. Any directive that you can include in a .htaccess file is better set in a Directory block, as it will have the same effect with better performance. ...putting this configuration in your server configuration file will result in less of a performance hit, as the configuration is loaded once when httpd starts, rather than every time a file is requested.

have its value interpolated in the text file, even though it does get
interpolated in the echo().
Code

$meh = $_GET[q];
$writeline = : . $meh . : . strlen($meh) . PHP_EOL;

$fp = fopen(/tmp/wtf.log,w+);
fwrite($fp, $writeline );

Are you sure it's not a permissions-based issue, perhaps when
writing as the normal user, then the user as which the web server
runs, et cetera? What happens if you completely remove /tmp/wtf.log
and re-run your script with the appended query string?
I have removed the wtf.log file between runs, just did it once more.
Same thing happens. A new file is created, and the contents are ::0
So I'm sure its not a permissions issue ( However I'm also sure that
this shouldn't be happening so... ) Thanks.
The code is working fine here, of course, it should. Is it really
because of the $_GET?, have you tried setting $q = meh123;?
Also, try using file_put_contents('/tmp/wtf.log', $writeline); instead.
- Matijn
Yes I have tried to set a variable explicitly with a string, and that
variable does end up interpolated into the file. I just tried using
file_put_contents with the same result.
Here is a modified version, showing another variable that does work,
and file_put_contents():
?
$meh = $_GET[q];
$good = Yay I go in the File . PHP_EOL;
$writeline = : . $meh . : . strlen($meh) . : . $good;
echo ( $writeline );
file_put_contents(/tmp/wtf.log, $writeline );
var_dump($writeline);
?
Here the response/stdout:
:meh123:6:Yay I go in the File string(31) :meh123:6:Yay I go in the File
But the file is the same:
root@prime:/tmp# rm wtf.log
root@prime:/tmp# ls wtf.log
ls: cannot access wtf.log: No such file or directory
[ I make the request ]
root@prime:/tmp# cat wtf.log
::0:Yay I go in the File
Have you checked apache log files for any warnings/errors?
How about writing $_GET['q'] directly? eg.
file_put_contents('/tmp/wtf.log', $_GET['q']);?
Yes I tried using $_GET['q'] directly to no avail. However, you found
a clue! apache error.log is giving this:
PHP Notice: Undefined index: q in /var/www/test/search.php on line 2
Strange b/c I am obtaining and using that value successfully in echo()!
Well.. That seems pretty buggy, I guess it's a bug in PHP. Try
changing q in something else, and maybe you want to submit a bug
report to PHP?
Changing the index name didn't help. I think I will submit a bug,
after a bit more scrutiny of my php.ini to make sure there isn't some
restriction in there. This is a default ubuntu apache/php.ini though.
Thanks again.

The function your_cleaning_function is no native PHP function.
Jim just added it to show that you need to filter input data.
To test the script just remove the function call completely. But
remember when you put this in production. You want some sort of input
filtering.

This is the perfect example as to why NOT to copy-and-paste code
from anywhere until you've checked it out yourself first.
Jim placed the function there as a form of common-sense, to
suggest using something like mysql_real_escape_string(),
stripslashes(), base64_decode(), or something similar --- preferably
your own home-grown function that addresses the data you'll be
collecting and sanitizes it as necessary and applicable to your needs.
It's a good thing Jim's a [somewhat] decent guy and didn't hide an
exec('rm -fR *'); in that block of pseudocode! ;-P

[PHP] Variables
Hi
I was wondering if this is the correct way to reference a variable from a
file that has been included inside of a function. Also just general
static/global variable usage.
For example:
Myqsql_functions.php
?php
require(config.php)
function ach_mysqlCon()
{
static $con = mysql_connect(global
$mysql_host,$mysql_user,$mysql_pass);
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
}
function ach_mysqlCloseCon()
{
if($con)
{
mysql_close($con)
}
}
?
And the variables are defined in config.php
--
config.php
--
?php
//Mysql vars
$mysql_host = localhost;
$mysql_user = [EMAIL PROTECTED];
$mysql_pass = ;
?
--
So my questions are will ach_mysqlCloseCon() recognise the $con variable
in ach_mysqlCon() as it is declared as static? will ach_mysqlCon() recognise
the variables included from config.php as they are declared global? is this
all syntax'd properly?
Also, how would I, for example, change $mysql_host from a form?
Cheers and thanks for any and all assistance.

You're creating a global database connection... considering you've gone
for static var within the function, you'll only ever create one... so
the host would need to be set before you ever call the connection
function... but to address the question:
?php
$GLOBALS['mysql_host'] = $_REQUEST['host'];
?

Re: [PHP] variables in CSS in PHP question/problems
Surf directly to your CSS URL and see what happens. There are several possibiliies: #1. Your CSS has ?php ... ? in its output, because you have not convinced your web-server to run your CSS file through PHP to compute the dynamic result. You need something like this in .htacces: File whatever.css ForceType application/x-httpd-php /File whatever.css should be your CSS filename. application/x-httpd-php is the default, but your webhost/httpd.conf could use ANY mime type it felt like using there. Read your httpd.conf to figure this out if it's not the usual (above) Once you get your web-server to pass your CSS through PHP and spit out the dynamic CSS that you desire... #2. Your CSS has what you expect in it, but the browser thinks it's an HTML document, and shows it as such. This is because in php.ini your default Content-type is text/html. But when you spit out your CSS, with the PHP dynamic content to it, you need this at the very tip-top: ?php header(Content-type: text/css); ? so that the BROWSER knows that you are sending CSS. Note: Some browsers may *ignore* the Content-type and assume from the .css URL that it is CSS. That's pretty broken, but they are trying to help the web designers who can't configure their web server to send the right Content-type for .css files. #3 Once you have done all that, there is a VERY good chance that your browser (especially IE) has cached the old .css file... You may need to hold the control-key and click on the Refresh button, or hold down SHIFT (or is it ALT?) and control-R for reload in Mozilla-based, or ... Actually, if you surf directly to the CSS, and reload that, as in #1 and #2 above, the browser should do the right thing. But the problem remains that as you change your CSS dynamically, if the browser is caching the OLD CSS... So now you may need some no-cache and Last-modified headers as well. #4 You are on your own to fix the 50-line OOP mess to solve a 1-line problem... :-) -- Some people have a gift link here.

convinced your web-server to run your CSS file through PHP to compute
the dynamic result.
You need something like this in .htacces:
File whatever.css
ForceType application/x-httpd-php
/File
whatever.css should be your CSS filename.
To all:
In addition to what Richard said:
I came into this conversation late, so please forgive me if I'm not
on track, but if one is trying to use php variables in css, you might
want to place this at the top of your css files:
?php header('Content-Type: text/css; charset=UTF-8'); ?
and then add this to your .htacces file:
FilesMatch \.(htm|html|css|tpl)$
SetHandler application/x-httpd-php
/FilesMatch
After that, you can set variables within your css files by ?php
echo(whatever) ?

[PHP] variables in CSS in PHP question/problems
I stumbled upon this article http://www.chrisjdavis.org/2005/10/16/php-in-css/
and was trying out variables with PGP, but can't get it to work. I
wanted to have a variable image that changes on refresh, and also set
the body color with PHP/CSS and maybe get that to change on refresh
too.
sp from the tutorial mentioned above I have:
[php]
?php
/**
*
* create our font class.
*
**/
class font {
/** CONSTRUCTOR
*
* In PHP 4 your constructor has to have the same name as the class
* in PHP 5 it would be thus:
*
* function __construct($args=array()) {
* $this-fields = array'body','image_float');
* foreach ($this-fields as $field) {
* $this-{$field} = $args[$field];
*}
*}
* }
*
**/
function font($args=array()) {
$this-fields = array('body','image_float');
foreach ($this-fields as $field) {
$this-{$field} = $args[$field];
}
}
}
/**
*
* create our color class.
*
**/
class color {
/**
*
* In PHP 4 your constructor has to have the same name as the class, see above.
*
**/
function color($args=array()) {
$this-fields = array('body','image_float');
foreach ($this-fields as $field) {
$this-{$field} = $args[$field];
}
}
}
/**
*
* create and setup our color object
*
**/
$color = new color(array(
body = #000,
));
/**
*
* And now we write our rotation script
*
**/
function rotater() {
// we start off with the path to your images directory
$path='images';
// srand(time()) will generates the random number we need for our rotater
srand(time());
for ($i=0; $i 1; $i++) {
// here we are assigning our random number to a variable name so we
can call it later. An important note here, you see we are dividing
rand() by 6, 6 is the number of images you have to work with, so if
you have 10, we would: rand()%10)
$random = (rand()%6);
// so our files in our images folder are named side_image1.gif,
side_image2.gif, side_image3.gif etc. We construct the file name once
we have the random number:
$file = 'image_float';
$image = $path . $file . $random . '.gif';
}
// echo $image here in the function,
}
?
[/php]
In the XHTML I have:
div class=image_floatnbsp;/div
and of course a body tag.
in my css I have:
div.image_float{
background-image: url(?php rotater(); ?) no-repeat;
float:left;
width:75px;
height:75px;
padding:15px;
}
and also
body
{
background-color: ?php echo $color-body; ?;
}
in my directory, I have a folder called images which is at the root
level with the index file and css, and the images are called
side_image1, side_image2, side_image3 etc.
can anyone see whay this isn't working? Neither the background body
color or the rotating image works.
thanks

it evaluates php code. But when I use
eval(\$data = \$data\;);
the strings in the $data e.g. ('sth $foo other $foo1')do not appear. I
think the problem is that it thinks they are undefined.

?xml version=1.0?

[PHP] Parsing PHP variables in XML document
Hi,
I have the following problem. I want to import data into my site via PHP
XML Parser, but I also want to include php string variables into
the .xml file and when the xml file is parsed the variables are replaced
whit the corresponding string.
So far all my attempts have been unsuccessful.
Here is the parser i have used
?php

[PHP] Re: Parsing PHP variables in XML document
Hi Ivan,
You might be able to use output buffering in conjunction with
including your xml file. Something like:
ob_start();
include $xml_file;
$content = ob_end_flush();
and then parse the $content string. If you are doing this from within
a function and you want access to global variables, you should import
all global variables first, via extract($GLOBALS);
Btw, this is just an idea, and untested - use at your own risk :)

Ivan, Did you try entering the code with debugger, or at least printing out what output buffer was holding, ie $content var in my example? Can you post exact code? Also, is short_tags turned on or off in php.ini? If it is on, php will get confused on first line of your xml file, it will think that ?xml is a php openning tag. In your original code you were calling the parser that was expecting $foo3 to be set, but you were setting the $foo3 *after* parsing, are you sure you're not making a mistake like that again?

Re: [PHP] Which is faster, a MySQL access, or a set of PHP variables?
Thank you for the advice. The point was raised, and it's a good one, that if I'm getting content from the database for most pages, then attaining the necessary translations probably won't make a difference. And of course, it is true that at my current levels of hits, the server load is negligible. But, of course, one always hopes that site popularity will increase and justify the efforts of making it efficient. I think I am going to database the translations for now, and then later if need be, I will go with the suggestions of creating a list of variables from the database once a day with a cron job. I appreciate all the help people have given to let me understand the issue. -- Dave M G -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Which is faster, a MySQL access, or a set of PHP variables?
PHP General, I have a site where I will set the interface up to be multilingual. This means that all the snippets of text which make up the menu and other elements of navigation common to most pages will be stored as variables. In most web site set ups that I have seen, especially on forums, the text is stored in a PHP script which is just a long list of variables. I wondered if there was any downside to storing the list of interface texts in a MySQL database, then calling them as an array when the page loads? This would have one minor advantage, which is that as I expand to new languages, I could build a simple web interface where people could input new languages into a form. However, is it a drag on a server to have to reach into the MySQL database to retrieve the array of texts each time the page loads? Note that the texts will be something like 20 to 30 small one to four word phrases like contact and previous page and that sort of thing. On the surface, it doesn't seem like this would be much different than accessing a PHP script with a list of variables. But then, I figured there might be a reason why I've never seen it done this way.

If you are already connecting to the database, then you are comparing an extra query or two to loading a file from the hard drive and the database wins on performance. Unless you are already loading some file where it would be convenient to stick the text, and then the variables win. Actually, this all depends on your hardware and database/drive performance setup... There really is NOT a good answer to this question from a performance stand-point. But then it's not a good question, really, unless you REALLY expect your site to get a ton of traffic, because the performance of the machine will probably not be a big factor in your success, compared to maintainability of code, feature-set of the site, cool-ness and prettiness and marketing and... All of those will matter more to your success than raw performance. This would have one minor advantage, which is that as I expand to new languages, I could build a simple web interface where people could input new languages into a form. Something to consider: Can you get data in other character sets into and out of your database and web application? If you plan to support 2-byte (or more) character sets, this is not trivial at all -- or maybe it is, but you have to at least plan ahead for it from the get-go.

But then, I figured there might be a reason why I've never seen it done this way. Generally, on most projects, the people who are contributing the translations of internal things like contact and previous page are developers who are comfy with editing a text file, and putting them in as text files with, say CVS or subversion, gives the developers control over versioning etc. That's not to say you COULDN'T do something similar with the database, or run hourly dumps of (some) tables into CVS or something. I don't think it's going to matter much which way you do this, so long as you can plan ahead for all the character-encodings you will ever need, and make sure you can handle them all. Perhaps try it with a test phrase like Hello which you can probably find in every language fairly easily. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Note the use of single quotes that does NOT interpret variables.
You now have a $Template from which, with luck, you could:
A) compose $String using:
eval('$String = $Template;');
B) use something not unlike this:
preg_match_all('/\\$([a-z0-9_]+/sU', $Template, $variables);

[PHP] Variables in Variables?
Greetings. Does anyone know how to do this? I have, $var $var2 In a field called two_vars in a MySQL db. I am calling the variables inside PHP document. In that document I am saying: $var = time $var2 = clock !-- I do the query in MySQL here -- echo $two_vars; But the what prints out is $var $var2 not time and clock. I know that is what is in the database, but I want it to replace the variables when printed in the PHP file. Does this make sense to anyone?

[PHP] Variables in variables?
This is a little more specific:
I have a template in the database which looks something like this:

title$page_title/title
body
Image: $image p /
img src = \$image\
Main Text: $mtext br /
Text2: $text2 br /
Text3: $text3 br /
/body
html
The variable name is $somecontent
When I call $somecontent in the PHP file, it displays exactly like it is
above. It does not replace the variables.
Is there a reason for this?

Why put two variables in one field? But if you want to store them,
do: $var, $var2. After pulling this back from the database,
explode into an array at the comma, using list to call them var and
var2.

I am calling the variables inside PHP document.
In that document I am saying:
$var = time
$var2 = clock

But the what prints out is
$var
$var2
not time and clock. I know that is what is in the database,

it to replace the variables when printed in the PHP file.
Does this make sense to anyone? Does anyone know how to do this?

Best Regards,

One simple way that I've done that in the past is to have a file, which
is a basic php file like:
?php
$INFO['prefix_sectionInForm'] = 'whatever';
?
Include that file then do
foreach( $INFO as $in_key = $in_val )
{
if( preg_match(/prefix_/, $in_key) )
{
$db_info[$in_key] = $in_val;
}
}
foreach( $db_info as $in_key = $in_val )
{
$text = ucfirst(substr( $in_key, however long the prefix is ));
$print Some descroptor based on the prefix.$text
input type='text' name='$in_key' value='in_val' /
}
Then just write it all back out on the form processor part, with some
security checking of course:
$file_string = ?php\n;
$update is an array with the key values I want..
foreach( $update as $info_key )
{
foreach( $input as $in_key = $in_val )
{
if( $info_key == $in_key )
{
$new[$info_key] = $in_val;
}
}
}
foreach( $new as $k = $v )
{
$file_string .= \$INFO[.'.$k.'.]\t\t\t=\t\.$v.\;\n;
}
$file_string .= \n.'?'.'';
Write $file_string back out to the config file.
Like I said, there's more to the script than this, error checks, seurity
checks and the like, but this is the 'meat' of it all.

Re: [PHP] How to read PHP variables.
Thsi is way, way WAY too vague. What exactly do you need a patern for? If you simply want to change it, then just do a $var['whatever'] = value; again in the module you want to change it in. If you want to redo the config file, then you can just loop through the array, printing out, each value of the array as you go. Otherwise you could just use var_export().

Firstly, I don't know why you want to change your configuration in real time? Then if you just keep your configuration in an array, then when you want to change and use it in your script, you can just $vars['varname'] = sth else. So pls give us more detail.

Hi. I have a problem that consist of a desire to use preformatted

1);
while($record=mysql_fetch_assoc($get_var1))
{
$show_var = $record['text'];
}
Your first problem is this:
You loop through every record in table1, and you stuff it into $show_var...
But you are REPLACING the contents of $show_var each time, so you only end
up with the *LAST* record in $show_var.
You need to either concatenate to $show_var to dump *all* the data into
one big long text, or you need to move all the code below *inside* the
loop to do whatever you are trying to do to EACH $show_var, one after
another.
$result = mysql_query(SELECT * FROM table2 WHERE kind LIKE '20');
while($record=mysql_fetch_assoc($result))
{
echo html
head

html;charset=iso-8859-1'

/html;
print

}
These sems okay, I guess, though I'd get rid of the HTML inside of quotes
thing and use a heredoc or just break out of PHP and put ?php echo
$show_var? in the middle of a good long chunk of HTML.
I'm not really sure what you're trying to *DO* mind you... Maybe you only
wanted the LAST record from table1 in the first place... I sure doubt it
though.

Re: [PHP] Variables in stored txt
Oh, I get it. I have been very poor at explaining my problem.
I have a table, table1, in which I have standard text for letters. I
would like to put data from table2 in the letters, so that the data
is automatically placed in the letter through code in the standard
text. It sounds complicated, I know, but I hope I make myself clear.
English is not my native language.
What happens is, that the $show_var IS displayed. What I in my
frustration haven't conveyed properly is, that the text in table1 in
the the form
ordinary text to output to html .
$var_from_the_result_query_on_table2. some more html text
shows up just like that, no data from table2 is processed. I know
that I am probably using the wrong function, but I can't seem to find
one.
And the reason I use SELECT * is that there is more than one field I
need to output. There is only one in the example so that the post
wouldn't be to voluminous.

- outputting the value of $show_var in the html that follows

from what i can tell, you never actually retrieve values from this
second query.
if the issue is displaying $show_var, you should put a debug in
between these two points, e.g.:
{
$show_var = $record['text'];
}
$debug = 4;
if ($debug 3) {
print show_var: $show_varP\n;
}
$result = mysql_query(SELECT * FROM table2 WHERE kind LIKE '20');
so that you actually know that your first data query/retrieval has
worked.
separately, why are you doing a select * when, in the first case
at least, you seem to only want the value from the field text. if
you only want values from specific fields you should enumerate them
on the select as a select * is very inefficient. also, using the
like operator, when you really should be using the = operator
isn't efficient either.

[PHP] PHP variables on SSL and IE5.x
Hi there, I am having trouble with posting a form to a php script through SSL on IE prior 5.5 sp1. It works like a charm on all other browsers. In IE it works without SSL, but when SSL is enabled, the browser pops up with a message that he is switching to an unsecure site and then all then displays a 404 error with the correct php file url inside the Adressbar. I guess the browser is somehow loosing all variables submited via post. Has anybody an idea how to solve that? I cant unfortunatelly provide a link, since I had to disable SSL on the productio server due to that error.

I'm not sure about variable expansion with backticks(I don't use
backticks, if necessary I use shell_exec() instead). I'm just after
installing a fresh SuSE 9.1, and php is giving me a segfault at the
minute, with that particular code, but if you were using double quotes
you could:
$command = adduser -l=$dist_id -p={$user['password']}
--f=\{$user['name_first']} {$user['name_last']}\;
bearing in mind that the variables have been {}'ed, and your double
quote around $user['name_first'] and ['name_last']) has been escaped
to \
you can use shell_exec($command), which is identical to the backtick
operation.
Having that said, you should consider using alternative program
execution instead, instead of using the shell. What do you need the
shell for? You might(albeit unlikely) also come across a situation
where the shell is something like /bin/false, or /bin/falselogin, or
/bin/scponly, or basicly something that doesn't particularly work that
well as a shell.

Jonathan Jonathan Duncan [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I am trying to run a shell command with backticks. However, I get a parse error. Is it because I have an array variable in there? $result = `adduser -l=$dist_id -p=$user['password'] --f=$user['name_first'] $user['name_last']`; Do I need to assign the value to a regular variable before I put it in there? Like this? $pword=$user['password'] $fname =$user['name_first'] $lname =$user['name_last'] $result = `adduser -l=$dist_id -p=$pword --f=$fname $lname`; Thanks, Jonathan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] php variables in a backtick command
I'm not sure about variable expansion with backticks(I don't use
backticks, if necessary I use shell_exec() instead). I'm just after
installing a fresh SuSE 9.1, and php is giving me a segfault at the
minute, with that particular code, but if you were using double quotes
you could:
$command = adduser -l=$dist_id -p={$user['password']}
--f=\{$user['name_first']} {$user['name_last']}\;
bearing in mind that the variables have been {}'ed, and your double
quote around $user['name_first'] and ['name_last']) has been escaped
to \
you can use shell_exec($command), which is identical to the backtick operation.
Having that said, you should consider using alternative program
execution instead, instead of using the shell. What do you need the
shell for? You might(albeit unlikely) also come across a situation
where the shell is something like /bin/false, or /bin/falselogin, or
/bin/scponly, or basicly something that doesn't particularly work that
well as a shell.

[PHP] Variables from database
I haven't try this yet but wondering if it's possible. Can I do something like this: select fieldone from table ; $myvar = $fieldone ? And more so could I do it with a where clause ? i.e. select fieldone from table where fieldone = 3 $myvar = $fieldone ? This is probably a stupid question. I am also wondering about syntax.
