[PHP] Variable names

2002-04-02 Thread kodrik

If I have a variable, how do I extract the name of the variable.

In principle:

$varname=somefunction($myvar);

The value of $varname is then "myvar"

How do I do it?

RE: [PHP] Variable Appended To The End of a URL Is Not Working in SQL Query

2002-04-02 Thread Rick Emery

Jason means that you should execute it from the mysql command line;
In your PHP code:  print $sql.
Then copy from that window and paste into mysql command line and execute.
What are the results?

The "your_variable" thing was just an example. It actually uses $id (an a
real URL).

Well, there's not $id variable.  And you're trying to select it.

Should be this:
$php_errormsg");
// next line has changed
 $sql = "SELECT * FROM tblArt WHERE IDArt = $your_variable";
 $cursor = @odbc_exec($db, $sql) or exit ("Error

Consider yourself lucky. Taking a variable supplied by a user and dumping
it into a SQL query like that is basically the same as printing your
database password on your front page. If it's a number, take intval() of
it. If it's a string, addslashes() it or make sure that magic_quotes_gpc
is on. And take your user-posted variables from $_REQUEST rather than from
the variables that get created automatically (which you should turn off
unless you REALLY know what you're doing because it's a dangerous
feature).

[PHP] Variable Appended To The End of a URL Is Not Working in SQL Query

2002-04-01 Thread Dr. Shim

I have a variable which is appeneded to the end of a URL, like

http://www.your_web_site.com/your_page/?your_variable=your_value

This would return "your_value";

echo $your_variable;

But this wouldn't work, and returns an error

$sql = "SELECT * FROM fldField WHERE IDField = " . $id;


What could possibly be wrong? If you need more info, then tell me. Here's my
code:

$php_errormsg");
 $sql = "SELECT * FROM tblArt WHERE IDArt = $id";
 $cursor = @odbc_exec($db, $sql) or exit ("Error
occrued:$php_errormsg");

[PHP] Variable Variables and Mulitdimensional Arrays

2002-03-15 Thread Charlie Killian

Hi. I want to be able to access a key in a multidimensional array at some
depth "n" without knowing before runtime what the keys are.

I thought this might be possible using variable variables. Here's some
sample code using variable variables and multidimensional arrays:
$y = 'a';
$z = 'b';
$t = 'c';
$x = array("a"=>array("b"=>array("c"=>TRUE)));

print_r($x{$y}{$z}{$t}); // Prints 1.


// I want to be able to concatenate the array indexes into one variable
variable. This would be done in a loop at runtime.
$u = ${$y.$z.$t};

print_r($x{$u}); // Doesn't work.

Any help would greatly be appreciated,

Charlie

Shouldn't be. A variable is valid from the point it's declared until 
it's unset(), or goes out of scope (the function within which it was
declared ends), or the script ends. 

Can you provide a short script which exhibits this behaviour?

I have a little chunk of code that checks to see if a variable exists and if

}

I then end that part of the php script after doing what I need to. Then I
start up again on the same html page and I assumed that $page had a value

this supposed to happen or is something weird happening. I added that little

[PHP] Variable problem with a function calling a ext. librairy

2002-02-21 Thread Marc Andre Paquin

Hello,

I created a librairy with configuration setting: background color, font size, 
customer's name, etc. Like this:
(lib_config.inc)

$bgcolor = "#ff";
$co = "ABC enterprise";

A second file is building html page headders:
(lib_intra.inc)

function title($name_section,$name_page){
print "\n";
print font_titre3."$co\n";
print font_titre2."$name_section\n";
print font_titre2."$name_page\n";
print "\n";
}

Finnaly, I call the title function in a web page to dynamicly create the code:
(test.php)

echo title("General presentation","The annual report");

My problem (you guessed it!) is that the file lib_intra.inc is beeing processed 
by php (when callled by my web page test.php) and the 2 variables are sent ok 
but NOT the $co wich is in the 1st file (lib_config.inc). Of course my 
lib_intra.inc has a: require ("lib_config.inc");

Because I dont want to duplicate infos that are used in many files, the 
lib_config.inc is important and must be called to supply the data I need.

How can I set this so all the variables will be process under php?

Thanks to all!

I think one $.
$func = "make_" . $wat;
$temp = $func($this);
will work

Use variable function names, like so:




Essentially, if you stick an argument list on the end of 
a variable name, that variable will be evaluated and used as
the name of a function to call.



Hope this helps,

RE: [PHP] Variable Problem

2002-01-19 Thread Philip Olson


Just to add a bit to this thread.  The following can be 
bad:

  
  
  

A potential gotcha.  Be sure to either define an array key 
and/or a value.  Because assuming all the above are checked, 
the following will result:

   $foo = array('on','on','on');

If two are checked, then we'll get:

   $foo = array('on','on');

Doesn't matter which two were checked :)  And as you 
guessed/know, if no value is set, 'on' will be the value as 
'on' is the default value for checkboxes.  And, if something 
is not checked, no value is passed at all.

That said, either do one of the following formats, feel 
free to mix and match, it doesn't matter.  Just know 
what you're doing :)

  

  

  

Then work with array foo as you see fit.  Be sure to read 
that faq (link posted earlier), it covers this.  Regarding 
your words, you guessed right, the second wrote over 
the first.  PHP requires [brackets] for arrays in forms.

And on a related note, a good way to "debug" arrays 
is through using print_r or var_dump.  You said you 
use PHP3, so use var_dump().

  var_dump($HTTP_POST_VARS);

It's been so long since PHP3 was cool, I barely remember 
how it works.  Maybe just try phpinfo() :)  But if 
track_vars are on, predefined php variables such 
as $HTTP_POST_VARS will exist.  And $foo should exist, 
anyway, enough on that.  Try hard to get PHP4 :)

  http://jp.php.net/manual/ja/language.variables.predefined.php

That page is in Japanese, hope it makes sense to you 
as it sure doesn't to me :)

Philip Olson

I hope im on the right track Cause im jumping in on this post.

 $MYCHK isn't an array cause you aren't using array syntax or simply left
out the brackets.

 try:

 ( for the checkboxes )
 
 

I have done this 100's of times.

I don't know whether the following works for PHP3, but for PHP4 you would use:

  
  

You could even use multi-dimensional arrays:

  

You would reference this as $MYFORM['CHECKBOX']['A'] in your php code.

Yes, I think too, it's better way to use an array rather than a dynamic

I thought that the first question means how to use a dynamic variable.

Does this technique work fine on the version 3.0.14 later to 3.0.18
 of PHP? (Not PHP4)

I tried an array in forms simply like below in the other day,
 but this didn't work fine...

( for the checkboxes )



Unfortunately, I had thought that it could be got as an array,
 but variable $MYCHK is overwritten by the last value "B" always.

(To mention about java servlet, this value could be retrieved by
 the syntax as below.

(HttpServletRequest)request.getParameterValues("MYCHK")[0]

off course, such a syntax occurs an error on PHP. ;D)

It's a good question, but why?  Most likely an array will work best for
this job, arrays are good:

  http://www.php.net/manual/en/language.types.array.php

The man page on foreach is nice too, and has many examples which include

How do I combine the following so it is treated as one variable

$i=10

$result$i="test";


I want this to be:


$result10="test";


$i changes so I cannot just put in 10 instead of I.


anybody know how i can do that?

What about

$i = 0; // set the start (or use for())
while ($i<$loopcounter) {
>   $temp = "size". $i; // $temp = 'size1', 'size2'...
$valueofsize = $$temp;
$i++;   # untested code, should be OK though
} 

No messing around with evals neccessary.

RE: [PHP] variable variables

2002-01-17 Thread scott [gts]

there's one example of var-of-vars along with arrays below my rant


var-of-var is almost always an evil thing.  there are some
rare instances where they're necessary, but i assure you
that your script would be MUCH cleaner and easier to modify
in the future if you used a simple array.

compare: $value = $form[$temp . $i];
to: eval('$valueofsize = $'. $temp . $i .';');


$form['size1'] = "hey";
$form['size2'] = "there";

$size1 = "hey";
$size2 = "there";
$loopcounter = 2;

while ($i++ < $loopcounter) {
$temp = "size";
eval('$valueofsize = $'. $temp . $i .';');
print $valueofsize;
print $form[$temp . $i];
}

[PHP] variable variables

2002-01-17 Thread Mike Krisher

I can not wrap my head around variable variables today, not awake yet or
something.

For instance I trying something like this:

while ($i<$loopcounter) {
$temp = "size";
$valueofsize = $$temp$i;
$i++;
}

this doesn't work obviously, $valueofsize ends up with a literal value of
"$size1". But I need it to equal the value of a variable named $size1. Do I
need to use a eval() or something?

$row["columname_$variable"] should do it.
$row[constant] is threaten as constant which is normally not the programmers
intention (set_error_reporting(0) and you'll see PHP's complaints about it)
so PHP converts it to $row['constant'].
You may now understand, that PHP "translates" your code to
$row['coloumname_$variable'] whre $variable is a string and not a variable.

Re: [PHP] printing php variable into html > print $result; ?

2002-01-03 Thread Philip Olson

A quick rewrite of your code:

";
  }

?>

Your question was how to print the query, in this case you'd just print
$sql.  That was the point of the above but I got a bit carried away :) Oh,
mysql_error() can be very useful for debugging.  Regarding the type
resource, have a look here:

[PHP] variable scope / preg_replace_callback question

2001-12-03 Thread Peter Bowyer

Hi,

Does anyone know of a way of passing other variables to the function being called by 
preg_replace_callback?  For instance, I have the following code:

function smarty_compile_lang($tpl_source) {
// en.php contains a very large array, $_lang
include_once '/home/test/en.php';
global $_lang;
return preg_replace_callback('/##(.+?)##/', '_compile_lang', $tpl_source);
}

function _compile_lang($key){
// If I include $_lang here then it gets
// loaded again and again - bad for performance as it is _very_ large
return $_lang[$key[1]];
} // End _compile_lang

Somehow I need to make $_lang global, or pass it through the function 
preg_replace_callback as an arguement for _compile_lang() - which I don't think is 
possible?

What can I do?  I've tried a global statement everywhere I can think of... and I don't 
want to include en.php outside the functions, as it'll be included then whether the 
templates are being compiled or not.  I'm 
guessing that I may want to look at a higher level of abstraction from these 
functions, as even if I have the include in the current place, it means that every 
time a template is compiled it gets reloaded (though that's 
not as bad as every time preg_replace_callback() finds something) whereas the best way 
would be to load it once per script invocation - and then only when the templates wer 
being compiled...

Suggestions?

Peter.

[PHP] Re: How to get mysql-result into a php variable

2001-11-17 Thread Fred

I'm not sure where you found the function mysql_store_result, but it is not
a built-in PHP function and that is why you are getting an error.

If you just want to return Match if one or more rows in the group match the
first name use something like this:

function LookupFirstname ($FName, $Group, $Conn)
{
$SQL = "SELECT .";
$Result = mysql_query($SQL,$Conn) or die (mysql_error());
if (mysql_num_rows($Result) > 0)
{ $Match = "Match"; }
else
{$Match = "NoMatch";}
return $Match;
}

[PHP] How to get mysql-result into a php variable

2001-11-17 Thread Olav Drageset

This is perhaps elementary, but I cannot find solution in the documentation

I want to transfer to a php variable wheter I find a matching firstname in a  group 
from mysql db

function lookupFirstname ($fname, $gr, $conection)
{ $sql =  "SELECT  firstname AS matches ";
  $sql .= "FROM persons ";
  $sql .= "WHERE firstname = '$fname' AND group='$gr';";

if (!$sql_result = mysql_query($sql,$connection) ) 
{echo "query: "; echo mysql_error(); }
  
  $store = mysql_store_result($conn);
  $result = mysql_num_rows($store);

 IF ($result > 0) {return 'match' ;} ELSE {return 'nomatch';}
}

I get error message that funcion mysql_stor_result() is not defined
How shall I use thees two funcions?

Thank you
Olav

RE: [PHP] Variable definitions...

2001-11-13 Thread Neil Kimber

BTW, the official explanation is wrong.

"local part this variable is destroyed and declared again"

is incorrect. The global variable is not destroyed. The local namespace
pushes the variable name onto the stack and gives it a value for the
duration of the function. Every time you try and access this variable it is
taken from the stack by the parser. Once you exit the function the local
namespace is destroyed and all the local variables are popped from the
stack. If the call stack is in the Global area then all variabels are
accessed from the heap,  so your original variable (and its original value)
are still accessible.

Re: [PHP] Variable definitions...

2001-11-13 Thread Chris Hobbs

Hi Stephan,

IMHO, I think the answer requested is the only one that really makes 
sense - as soon as I read it, _my_ first thought went to scope.

If a variable changes values, the other value is no longer usable, and 
thus there aren't really two variables with the same name in that case. 
When comparing global to local scope, however, you can definitely have 
the same name in use in two places.

Of course, I wasn't a CS major, so someone else might be able to give 
you an answer that will help you justify yours - but prima facie, you 
got it wrong :(

Now, if you're talking about the compiler level, then no two variables 
(which are actually memory registers at this point, iirc) can share the 
same memory space with different values - this is just logically 
impossible. But the question is certainly referring to source code, and 
so scope is the only reasonable answer.

HTH!

[PHP] Variable definitions...

2001-11-13 Thread Stephan

Hello,

first of all I didn't exactely know where the right place is to ask this
question.

Well, my problem is that I just had some exams and am very unhappy on
how certain things were rated.

There's especially one question and I try to translate it as exact as
possible:

When is it possible that two variables have the same name but display
different variables?

The official solution was when in a script a global variable is declared
and then in a local part this variable is destroyed and declared again
with the same name (maybe even using different data type).

As for me, I'm of the opinion that this definition according to the
question is too narrow minded. I think that a variable is already
different if the the value within the variable is changed due to script
OR if you appoint a new value to the variable OR if the variable is an
array and some elements are accessed / elements are added / elements are
removed.
The reason why I think variables with different values can be considered
as different variable according to the question asked in the exam is
that when you declare a variable it also has a value even if this value
is NULL.

Now I'd like very much to hear your opinion on this issue since for me
very much depends on that (3 years of studying at college).

Spunk

Could you post some excerpted code please? 

You seem to have multiple issues:
1 communication between a 'mainline' and INCLUDEd code
2 communication between a 'mainline' and a function
3 working with scalars and arrays
4 working with text strings and ?text arrays
- which may or may not be related/relevant

Let's start with simple ideas:
0 put debug echo statements into the function (or everywhere) to track progress
1 if you take the processing code out of the INCLUDE file and put it in the 
'mainline', does it then work as planned?
2 do you have an & to indicate a pass by reference cf a pass by value (see manual)?
3 and 4 does the processing use tools/approach/functions that only work with 
scalars/arrays/strings?
A process of elimination...

Keep us posted,
=dn

[PHP] variable gets lost in function problem again...

2001-10-26 Thread Spunk S. Spunk III

Sorry all but I really need to figure this out. Here's a recap of my
problem:

I have an two dimensional array that is returned from code from an included
file. I'm assigning parts of the array to variables ( $variable =
$array["key"]["value"]; ). This works fine and can be printed until I send
it through a function eg. ( ereg_replace(" ", "_", "$variable"); ). After
this, $variable is blank.

I don't think it's my code because substituting a text string for the array
data (eg. $variable = "this is some text";) works just fine.

It has something to do with the assigning array data to a variable or
perhaps that the data comes from an included file... This could be a bug in
PHP? 

Does this sound familiar to anybody? I can't figure it out! Any help would
be much appreciated.

Thanks,
Spunk

[PHP] variable operators in queries

2001-10-19 Thread Sander Peters

Hello,

Is it possible to put variable operators in queries?
I tried this (the real variable comes from a form)

$Date_Operator =(">=");

sql="SELECT * FROM poeple WHERE age $Date_operator 20";
$result_id = mysql_query($sql);

It doesn't work like this. I also tried:

sql="SELECT * FROM poeple WHERE age \"$Date_operator\" 20"
$result_id = mysql_query($sql);

it didn't work either.

Or should I use a have to make a IF-Then construction?

If $Date_Operator == (">=")
then
{
sql="SELECT * FROM poeple WHERE age >= 20"
}
etc...




Can anybody help me with this?

Thanks in advance!

[PHP] Variable & Configuration Problem

it.

The problem I have now is this:
I want to read the data passed from a form trough a variable.
Let's say the form field is called Test. I want to use $Test in my PHP script to read 
that variable.

But all variables stay empty. I don't wan't to use the Query_string to get my 
variables.

Can anybody tell me what INI-setting(s) I got to turn on or off??

Re: [PHP] Variable declaration

2001-09-27 Thread

> > its really a big headache with compilers like c bugging all the way just for 
>declarations.

One remark, btw. Using explicit declarations isn't really more of a
headache then _not_ using expl.decl. When you don't
use explicit declarations, you'll need to check wether or not a
variable is defined at (almost) any point where you want to use it.

But... like I said; it's more a matter of preference.

Only thing is that when I look at quite a lot of people who post on
this mailinglist, I think it shouldn't be such a bad idea to force
them into coding a bit stricter. Many people just start using
variables "because they'll probably already been defined". That's
not something you can depend on. Same with people who think they can
just use variables that have been posted from a form. No need to
check them for being defined?!? I think you should. You cannot
depend on user-inputs. And there's always a possibility of people
bookmarking specific pages or typing URL's themselves. You'll always
need to check variable before you use them.
Explicit declaration at least address a part of this problem. It
forced people to code a bit stricter.

I think it's just a matter of preference. I like this, you like
that. No harm to that. That's why I proposed the
E_EXPLICIT_DECLARATION. That way I can choose to use it, and you can
leave it for what it is. Kinda like what Perl does with "use
strict;". If you don't like being forced to declare every variable
before you use it, you just don't type "use strict;" at the start of
your script. People like me, who do like to do that, _do_ use that
option. Everyone gets it his/her way and it bothers noone.

But anyway... I don't think they'll ever implement this, so (...)

NOTE:
PHP Rulz and this is just a small thing that doesn't change anything
to the superb power of PHP webbuilding! :)

That is the nature of a loosely typed scripting language.  If you prefer a
strongly typed compiled language, there are plenty of those available.

What he (Alberto) is looking for, and what I would prefer to, is to
really explicitly declare a variable. There's a difference between a
compiler that requires you to declare (integer $Test;) a variable
_before_ you start using it ($Test = 3;). Ofcourse I know that PHP
internally declares it, but it's not the same thing.

When the compiler forces you to declare all variables you're gonna
use it gives a better view of which variables are used in the
script, and besides that it doesn't allow you to make any mistakes
of using undefined variables like it does now.

The PHP compiler doesn't really check your code intensively. You can
use any variable without the compiler complaining. Only at the
moment that it reaches the variable and finds out it isn't defined,
it tells you. It would be better to explicitly have to declare the
variable. When the compiler starts it then shouldn't execute the
code when it contains any variable that is not explicitly declared.

But like I said, FAFAIK explicitly declaring variables isn't
supported by PHP :(

Nop! This is just starting to use a variable. Something like:

What do you mean force declaration?  That's what you are doing with this
line:

  $Test = 3;

This declares $Test to be an integer with the value 3.  Assignment and
declaration is done in one step.  There is no mechanism to do it in two.

Re: [PHP] Variable variables

2001-09-26 Thread Philip Olson


If I'm reading your snippet correctly, then :

  $foo = 'bar';
  $bar = array('apple','banana');

  print ${$foo}[0]; // apple

Note the use of {braces}.  The last paragraph in the manual describes this
a bit :

  http://www.php.net/manual/en/language.variables.variable.php

Although I don't see the point of $newvar as you're keeping track of $a in
the array itself.  Looks like the below code will create a ton of
variables (arrays) each with one $a as the single key.  Just using
$finalresult may be more appropriate, hard to say.

And some tips :

  $arr[foo] will create an error/warning here, $arr['foo'] will not.
  "$foo" isn't as pretty as $foo

Philip Olson

[PHP] Variable variables

2001-09-26 Thread Richard Baskett

I can not figure out why this is not working!

for ($j=0; $j<$resultNum; $j++) {
  $newvar = "finalresult".$a;
  $$newvar[$a][name] = $resultRow[name];
  $$newvar[$a][title]= $resultRow[title];
  $$newvar[$a][descript] = $resultRow[descript];
  $$newvar[$a][countkey] = substr_count("$resultRow[keywords]", "$keyword");
  a++;
}

This is how you use variable variables, is it not?  Is it because it's a
multidimensional array?  or am I missing something else?

I'd say there are 2 solutions: 

1) Set the default value in the dropdown box to '%'.

2) Just set $cat to whatever you want, when it is 'x'
if ($cat == 'x')
{
$cat = '%';
}

There are several possible solutions here, starting with seting a default 
selection in your dropdown so you avoid the problem.

Otherwise you could test whether the dropdown value is empty, and if so, 
not add the 'AND productcategory.ID' clause to your select.

[PHP] variable variables and eval

Hash: SHA1

Hi All,

i have come across a strange problem with variable variables. Basicly i'm
doing the following and its not working:

$section = 'data["SITE"][0]["NAME"][0]';
$pData = 'My Site.';
${sprintf('$%s', $section)}.=$pData;

but it is not working. But if i do this:

eval('$'.$section.'.="'.addslashes($pData).'";');

it works and all is well. I don't really want to use eval() and just
wanted to see if anybody has any ideas why the above doesn't work.


Thanks,
William.

RE: [PHP] Storing Java Script Varable into php variable

2001-07-20 Thread Erik H. Mathy

Hi Mike!

Generally the only way to send information from a clientside javascript to
a serverside language (in this case PHP) is via a form submit or putting
that value into an HREF the user will click. For example:












Save your screen settings...

(please note: this is all rough code off the top of my lacking caffeine
head...it has not been debugged or anything else. or in other words, it's an
approximation. ;] )

Hope this helps,
- Erik
