 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;
php  echo ${distributor-42-2};
5

I think that's it.

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.

   I don't want to see what the script is, for example I don't want it

   Is this possible through PHP only, or do I have to write a rewrite

 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

As this method requires an Apache restart, I don't see what advantage

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.

Hello, when I pass a variable whose value originally came from $_GET

 Code

 Request 

/search.php?q=meh123

 Response --- ( expected )

:meh123:6 string(10) :meh123:6 

 Contents of /tmp/wtf.log 
::0

Some sort of security setting in php.ini maybe? If so, I'm not only
curious in how to fix it but also how this actually happens. Does the
value assigned to $writeline not get immediately evaluated? I mean,
does $writeline know it contains variables from elsewhere, instead
of just containing a string of chars?

Thanks!


I'm not at all sure what's going on with your code and/or site. Please  
look at:

To see the php code, and:

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

The code is working fine here, of course, it should. Is it really

    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

 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);

 --
 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?

It's all wrong looking :/

Myqsql_functions.php

require(config.php)

function ach_mysqlCon( $init=true )
{
static $con = null;

if( $init  $con === null )

$con =

}
}
}

function ach_mysqlCloseCon()
{
if( ($con = ach_mysqlCon( false )) )
{
mysql_close( $con )
}
}

?

 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'];

?

I've intentionally used request since I don't know if you would do it

Re: [PHP] variables in CSS in PHP question/problems

[Richard Lynch]

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... :-)

?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) ?

I believe what Jochem is trying to tell you is that when you assign the
string variable, the variable names are expanded to their values, so the
names are no longer available.


exactly - nicely put Jim.



Consider this:

$partname='widget';
$amount=100;

$string=This $partname costs $amount dollars;

/*
$string now equals This widget costs 100 dollars, so when you pass it to
your function, it has no way to know for sure what the variables were, or
that there even were ANY variables involved in the generation of the string.

The variable NAMES are not passed because PHP expands them to their values
and sets $string accordingly.
*/

$string='This $partname costs $amount dollars';

$string now equals This $partname costs $amount dollars.  In this case, I
used single quotes.  The values are not expanded and the variable NAMES are
passed.  The VALUE of the variables are not.  So you could then have a
function look for any word that starts with a $ and return an array of
names.

There is *NOTHING* left to indicate that xyz came from a variable.

You simply do not have the context available to do what you want.

Now, you *COULD* do like this:

$VarName = 'xyz';
$Template = 'Blah Blah Blah $VarName Blah Blah Blah';

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, $variables);
foreach($variables[1] as $varname){
  echo $varname = , $$varname;

Keep in mind that the variable name in a double quoted string is
interpreted, you would have to use an outside process to read each line of

 Hi. I have a problem that consist of a desire to use preformatted
 text in a while-loop while inserting data from another search. The
 code is as follows:


 

 $get_var1 = mysql_query(SELECT * FROM table1 WHERE id LIKE '1' LIMIT
 1);
  while($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
  meta http-equiv='content-type' content='text/
 html;charset=iso-8859-1'

  /td
  /tr
  /table
  /body
  /html;
  print 
  script type='text/javascript'
  window.print();
  /script;
  }

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

[Niels Riis Kristensen]

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.

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.

 $pword=$user['password']
 $fname =$user['name_first']
 $lname =$user['name_last']
 $result = `adduser -l=$dist_id -p=$pword --f=$fname $lname`;

 Thanks,
 Jonathan

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.
you can use extract()

Good.

 The second and third pages [edit-news-x.php/ edit-submit.php] are pure php
 (a pass-through page) -- I wasn't aware they needed these tags as well. Hmm

I'm not sure what you mean by pass-through page. But whenever you're using any 
form elements then they should always be wrapped with properly constructed 
form tags. Some browsers are more lax than others but you should always try 
to make your pages browser independent particularly when it comes to 
something as basic and mundane as forms.

Hi Jason,

Yes the first page has the appropriate form tags:

{edit-news.php]
form action=edit-news-x.php method=post . . . /form

The second and third pages [edit-news-x.php/ edit-submit.php] are pure php (a

Thanks -- I've stared at these pages way too long. Also, it's not my code, but 
I'm patching new stuff into working code - oh ugh!

Thanks,
I'll try adding the tags.

Why not just unset the variables you don't want in the list?

?php

$uservars = get_defined_vars();
unset ($uservars['_SERVER']);
unset ($uservars['_ENV']);

 I am relatively new to PHP. But something I can't seem to make work is

 I call one of the functions I have made and a variable is set inside that
 function
 eg. function blah ($bl,$ah) {
 $bl++;
 $ah++;
 $blah=$bl+$ah;

 I then echo $blah; somewhere else in the script but nothing is echo'd. How
 do I make it so that I can use $blah anywhere in the script?
 
 Thank you in advance for any help.

RE: [PHP] Variables inside a function

[Alex Hogan]

If I read his post correctly he was looking to make blah() available and not
$blah.

In my mind that meant that he would be calling his function named blah not
the variable.

Then if he called the function blah he would get the value of $blah inside
his function.

Of course obviously being one of the OP you refer to I have read the manual
 Variables  Variable scope.  In this case I don't see how it related to
his post, even though he stated that he was trying to echo $blah

One of those letter of the law vs intent of the law sort of things.

But thanks for the condensintion..., maybe I can return the favor sometime.

I went back and re-read the post, and his question above is the
important one

First you must return something from the function, then you must assign
the returned data to a variable...

long-hand

function blah ($bl,$ah) {
 $bl++;
 $ah++;
 $blah=$bl+$ah;
 return $blah;
}


$dork = blah($foo, $bar);

$dork is now the value of the returned $blah and $dork may be used with
the value over and over until it is re-written or over-written

Re: [PHP] Variables not passing...

[daniel]

Is there a session_start() on the second page ?

Also i didnt know u could set an action to a jscript popup, it may not be
posting to the second page. What you could try is posting to the second
page like a normal post, u need to do something like


session_start();
$_SESSION['startdate'] = $_POST['startdate'];
$_SESSION['stopdate'] = $_POST['stopdate'];

in the second page

u only need this if u are then redirecting to yet another page

else just do a

 h1 align=centerstrongReports received between ?php echo
 .$_POST['startdate'].; ? and ?php echo $_POST['stopdate']; ?
:/strong/h1


something like that


 Okay, I am sure this will be painfully simple, but I have looked it
 over for a couple of hours now, and I am obviously missing something.
 I am trying to get a start date and a stop date via input from a user
 to use as variables in a MySQL query, but for some reason, I can't get
 the variable to pass from one page to the next...  Will one of you
 masters help me find my goof?

 First page has the following at the top of the code:
 ?php
 session_start();
 $_SESSION['startdate'] = $startdate;
 $_SESSION['stopdate'] = $stopdate;
 ?


 Then I am getting the data entry in the following form code:
 form name=viewbydate method=post
 action=javascript:popUp('viewbydate.php')
  li All reports from one date to another: Start
input name=startdate type=text size=15 maxlength=30
Stop
input name=stopdate type=text size=15 maxlength=30
input name=button2 type=submit value=GO
  /form


 The second page starts by displaying this info:
 h1 align=centerstrongReports received between ?php echo
 $startdate; ? and ?php echo $stopdate; ?:/strong/h1


 The regular text displays, but there is just white space where the
 $startdate and $stopdate should be.

 Thanks in Advance!!

Re: [PHP] Variables not passing...

[Chase]

One other irritation for the evening...  The MySQL query that I am trying to
create needs to use the date the user enters and then add  @ 12:01am EST
to it so it will acutally match the data in the table.  Below is my quesry
line, but I don't know how to add that chunk to each of the variables...

$result = mysql_query(SELECT * FROM $table WHERE 'submit_date' =
'$startdate' AND 'submit_date' = '$stopdate' ORDER BY 'submit_date' DESC,
$link);

 Is there a session_start() on the second page ?

 Also i didnt know u could set an action to a jscript popup, it may not be
 posting to the second page. What you could try is posting to the second
 page like a normal post, u need to do something like


 session_start();
 $_SESSION['startdate'] = $_POST['startdate'];
 $_SESSION['stopdate'] = $_POST['stopdate'];

 in the second page

 u only need this if u are then redirecting to yet another page

 else just do a

  h1 align=centerstrongReports received between ?php echo
  .$_POST['startdate'].; ? and ?php echo $_POST['stopdate']; ?
 :/strong/h1


 something like that


  Okay, I am sure this will be painfully simple, but I have looked it
  over for a couple of hours now, and I am obviously missing something.
  I am trying to get a start date and a stop date via input from a user
  to use as variables in a MySQL query, but for some reason, I can't get
  the variable to pass from one page to the next...  Will one of you
  masters help me find my goof?
 
  First page has the following at the top of the code:
  ?php
  session_start();
  $_SESSION['startdate'] = $startdate;
  $_SESSION['stopdate'] = $stopdate;
  ?
 
 
  Then I am getting the data entry in the following form code:
  form name=viewbydate method=post
  action=javascript:popUp('viewbydate.php')
   li All reports from one date to another: Start
 input name=startdate type=text size=15 maxlength=30
 Stop
 input name=stopdate type=text size=15 maxlength=30
 input name=button2 type=submit value=GO
   /form
 
 
  The second page starts by displaying this info:
  h1 align=centerstrongReports received between ?php echo
  $startdate; ? and ?php echo $stopdate; ?:/strong/h1
 
 
  The regular text displays, but there is just white space where the
  $startdate and $stopdate should be.
 
  Thanks in Advance!!

Escape it.

$string = \\;

Or, use single quotes:

$string = '\';

Re: [PHP] Variables not working!

[Alvaro Zuniga]

Try this for a generic fix if it is the globals issue:

Place this somewhere to set to TRUE or FALSE when needed

$GLOBAL_FIX  = TRUE;

use an include on every script:

if($GLOBAL_VARS_FIX) {
   if( phpversion() = '4.2.0' ) {
  extract($_POST);
  extract($_GET);
  extract($_SERVER);
  extract($_ENV);
  extract($_COOKIE);
   }
}

Hi Kaushan

Little bit difficult without seeing the code, but what you are probably sitting with 
is an 
issue with globals - depending on your method of submitting (GET or POST)you can try 
and check one of these two $_POST['fname'] or $_GET['fname'] for the value of the 
text field.

RE: [PHP] Variables not working!

[Larry Brown]

It is most likely globals.  Access the variables by...

echo $_GET['fname'];

or $_POST['fname']; if you are using post which it doesn't appear you do.

Larry

PS it is adviseable to leave globals alone in php.ini since it is set that
way for security concerns.

I have some code to pull a question out of a database and display it on

Currently, the display bit works fine.
The only problem is the hidden var only has the first word of the

Eg.

If the question is: What is the problem with this stupid thing?
The hidden var will contain: What
What am I missing? Why has the rest of the question packed it's things

Code Snippet

while ($newarray = mysql_fetch_array($result)) {

$question = $newarray['question_text'];
echo brfont face =
