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'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?

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."

You can add this to apache conf:


ForceType application/x-httpd-php


Then make a file called phpscript without extension and drop it in the
web root.

Re: [PHP] Variables are empty only in fwrite

Hello, when I pass a variable whose value originally came from $_GET
or $_REQUEST to fwrite, fwrite behaves as if it was passed an empty
string. Note that the file is successfully opened and written to by
the script, but the variable that originally came from $_GET does not
have its value interpolated in the text file, even though it does get
interpolated in the echo().

 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!

Is that definitely the exact code you're running? Nothing added, nothing 
removed? I ask because it works for me...

 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

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.

 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.

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

 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.

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()!

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 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():



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

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.

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.

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?

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

In your form, do this






Then in PHP do this.  This is if the form was sent via POST

 $packages ) {
 foreach ( $packages AS $package_id => $value ) {
 // At this point, the only way you would get here is if
 // a person was to place a check mark in the check box
 // So, one would assume that this component/package
 // combo was infact checked.
 }
}

?>






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.

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:



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

check/filter/process the submitted value before being so careless as to

"variable variables" will do it.

But 99.% of the time, you're better off just using an array.

Surf directly to your CSS URL and see what happens.

Your CSS has  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:


  ForceType application/x-httpd-php



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:



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.

You are on your own to fix the 50-line OOP mess to solve a 1-line
problem... :-)

does php interpret the file or not?
you can decide it if you request the css file directly with a browser.
if you see 
  ForceType application/x-httpd-php
"
(quoted from Richard Lynch's earlier post)

another problem may be if you do not send correct content-type header.
the first line should be something like



before the css stuff.

*I did not read your full email, sry...
But i think you are not right using PHP in this case, or atleast not
in this way.
There are 2 ways to solve this quite easy
1) use javascript to randomly select a image from a predefined array.
example:



var theImages = new Array()

theImages[0] = 'images/001.png'
theImages[1] = 'images/002.png'
theImages[2] = 'images/003.png'
theImages[3] = 'images/004.png'
theImages[4] = 'images/005.png'
theImages[5] = 'images/006.png'
theImages[6] = 'images/007.png'
theImages[7] = 'images/008.png'
theImages[8] = 'images/009.png'
theImages[9] = 'images/010.png'
theImages[10] = 'images/011.png'
theImages[11] = 'images/012.png'
theImages[12] = 'images/013.png'
theImages[13] = 'images/014.png'
theImages[14] = 'images/015.png'
theImages[15] = 'images/016.png'
theImages[16] = 'images/017.png'
theImages[17] = 'images/018.png'
theImages[18] = 'images/019.png'
theImages[19] = 'images/020.png'
theImages[20] = 'images/021.png'
theImages[21] = 'images/022.png'
theImages[22]= 'images/023.png'
theImages[23] = 'images/024.png'
theImages[24] = 'images/025.png'
theImages[25] = 'images/026.png'

var j = 0
var p = theImages.length;
var preBuffer = new Array()
for (i = 0; i < p; i++){
  preBuffer[i] = new Image()
  preBuffer[i].src = theImages[i]
}
var whichImage = Math.round(Math.random()*(p-1));
function showImage(){
document.write('');
}


2) or you could generate the images with PHP
so you would call your image with http://server.com/myimage.php";> (or maybe from CSS.
and your myimage.php would contain something like


And that should do the same

$VarName = 'xyz';
$String now has "Blah Blah Blah xyz Blah Blah Blah" in it.

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;
}

I'll warn you right now that whatever it is you are doing, there is
PROBABLY a better easier way to do it, but you've put on blinders to
other solutions and only asked us how to do what you think you want to
do, which is probably not what you really want to do...

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

your function MySpecialFunction() will recieve the following string:

which apart from being (probably) incorrect SQL, is just a string -
how is your special function supposed to tell which chars are part of

how would the function find out what those variables we're called to
begin with (it can't).

I'm not sure what your trying to do but well,

The 'problem' was in fact register globals. I did a little research

$_POST['foo']. Thanks.

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.

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  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_var\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.

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'];
 }


$result = mysql_query("SELECT * FROM table2 WHERE kind LIKE '20'");
 while($record=mysql_fetch_assoc($result))
 {
 echo "  
 
 
 test
 
 
 
 
 
 
 
 
 
 
 
 
 ".$show_var."
 
 
 
 
 ";
 print "
 
 window.print();
 ";
 }

_

Needles to say, I hope, that it doesn't work!

[PHP] Re: php variables in a backtick command

[Jonathan Duncan]

So I tried it that way and it worked, that is annoying though, having to add 
extra lines to the code and assign the contents of one variable to another. 
Any way around this?

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 
 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  tags:

{edit-news.php]
 . . . 

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 . . 
. that might explain why they weren't passed -- I must be getting old :> . . 
.

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?



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

How
do I make it so that I can use $blah anywhere in the script?
[/snip]

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

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.

Don't you need to set a return?

Return $blah;

At the bottom of your function block.

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);

Thank you!  It looks like it was a combination of my NOT using the $_POST

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

> Reports received between  "".$_POST['startdate'].""; ?> and :


something like that

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);
   }
}

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.

Subject: [PHP] Variables not working!


Hi,

I am new to PHP scripting and struggling with the following problem.

I have two files, an HTML file and a PHP file.
HTML file contains a form with one text field and a submit button.
When a user pressed the submit button, it calls the php file ().
What the php file does is just echo back the text  received from html file
to the user again.
Name of the text field is 'fname'. When I used this variable in the php file
(as $fname) it does not contain the value of the text field. Query-string
appended to the url during the submission is also correct.
I checked for all syntax errors, but the codings are perfect.

Do I have to change php.ini file to fix this problem.

Could anyone can help me to solve this problem.

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.
