Hi all,
I've found a strange bug with extract($GLOBALS, EXTR_REFS), and it
only shows up if you try to access a non-existent variable or array
member before that. Here's a demo script:
// Uncomment this line to see the problem
// $return = @$_GET['xx'];
function extr_globals() {
extract($GLOBALS, EXTR_REFS);
};
function test($msg) {
$x = 'OK';
$msg = 'wrong';
return $x;
};
echo test('login') . "\n";
extr_globals();
echo test('login');
If you run this script, it will output two OKs, as it should. If you
however uncomment the first line, one with $_GET assignment, it will
output an OK and then text "wrong". Tested with php 4.3.10 and 5.0.3 on
a windows machine.
What actually happens is that extract($GLOBALS, EXTR_REFS) really messes
up nametables. If you step into test function with debugger, you will
see that all variables inside the function will already be "initialized"
to the value of the parameter $msg, and assigning to one var will
overwrite values in unrelated variables. I repeat, this only happens if
you tried to access non-existent var or array member before that.
So it's a bug. Do I get a PHP T-shirt ? :-)
Boban.

Yeah, that was my instinct too... Just could not find anything to
confirm it after a quick browse through the spec. Though can you find
anything in the spec via a quick browse.. ;-)
However, after a closer look I still can't find (at least in plain
English) anything that says this is NOT OK. Though the parser does
return '[xml_error] => not well-formed (invalid token)'.
Good stuff....

Thanks for the options David.
I think I'll go for the last option as I'm determined to get to grips
with REGEX, and your first choice of REGEX won't work for me as the
'RV-6' bit can be too variable with what it contains, whereas the \(EX\)
bit IS more constant...it's only the EX bit that changes.
I knew I had to to escape some characters but got confused as to how
many times to do each one.
I have tried using your example as follows:
$postScriptData =preg_replace("/\\\(.*?\)\\/","",$postScriptData);
and get the following error:
Warning: No ending delimiter '/' found in...
Any suggestions?
Cheers
Alexis

I assume that the text inside can change around a fair bit. If the
string is of a fixed with or simple format you can just use substr() and
friends, it's simpler and faster.
That said, there is really two approaches that I can see with this string.
You can match on the spaces to extract the 'RV-6', something like
'/\s\S+\s/' should do the trick, that pulls out some non-whitespace
characters from between two whitespace characters, including the
whitespace characters. Then just add the () on again afterwards.
The other approach would be to use preg_replace to get rid of the \(EX\)
portion by replacing it with an empty string. Personally I would
probably use the first technique as I generally don't like using replace
functions in this way. A pattern which should match is '/\\\(.*?\)\\/',
the mess of \ is because \ ( and ) all need to be escaped with a \.

Hi,
I'm still trying to get to grips with REGEX and have hit a hurdle with
the following:
I have this bit of text:
(\(EX\) RV-6 )
I want to remove the '\(EX\)' part of it
so leaving just: ( RV-6 )
Any suggestions would be most appreciated.
Thanks

I simple wrote a small C program that basically sent a bell, 0x07
and it opened my cash drawer. In php I just did system('bell'); and
it worked fine.

Hi:
Interesting! The statement system('bell'); is new to me.
If I'm writing code on a hosted domain, and using that statement,
who's bell am I ringing?

bell is his C program... :) Outputs an ascii 7 (bell) at the machine
where it runs. It basically outputs a character to stdout or stderr.
He probably has that machine next to his cash drawer...

Ask not for whom the bell tolls, it tolls for thee!

Hi,
I have a class in PHP which offers some API functions. I want to access
this API with other languages (such as C/C++, Java, Perl, etc), so the
functions will run from PHP.
How can I do that?
-thanks.

I could be wrong on this, but I think your best hope is something
using web services like SOAP, or XML-RPC.

Sorry if this question seems stupid - I've only had 3 days of PHP
experience.
When using the following string format, I get an error from PHP.
$text['text'] = "String Text" ;
Can someone help me?

This seems ok and should not give any error. Mabye the error is of
something else.
What's the error you get?

Hi Philip,
If that's literally a line from your script, my guess is that "text"
is a reserved word and can't be used as a variable name. Try $sText
or $sSomethingMeaningful.
In this and future postings, it would help us help you if you share
all relevant details such as the exact error message you see.
I've gotten into the habit of prefixing all my variable names with their type:
$aSomething - array
$sSomething - string
$iSomething - integer
$nSomething - numeric
$bSomething - Boolean
In a language like PHP in which data typing is so loose, I find that
prefixing the variable type a) helps me keep variables straight and
b) prevents me from inadvertantly using reserved words as variable names.
Great resource:
http://php.net/
You can quickly look up details from the reference guide by entering
key words after the domain name, for example:
http://php.net/array
gets you a page of array functions.
Have fun,
Paul

could someone please help me on that one? http://hashphp.org/pastebin?pid=6156
basically this is how I do:
I display a mysql table in an html table and I put each value in an
input text box.
At the bottom I put a submit button to update changes.
My question is how do I update everything knowing that I don't know in
advance the name of all the input textbox?
Here is the code to display the table:
<table width=\"1\" border=\"1\">
<tbody>
<tr>
<td><strong>English</strong></td>
<td><strong>Français</strong></td>
<td><strong>Español</strong></td>
";
$getdisplaycatname = "select
catid,categoryfr,categoryen,categoryes,categoryar from category";
$getdisplaycatnameq = mysql_query($getdisplaycatname);
while ($getcatrow = mysql_fetch_array($getdisplaycatnameq)){
//$display_category=mysql_result($getcatnameq, 0);
$showcatid=$getcatrow['catid'];
$showcat=$getcatrow['categoryfr'];
$showcaten=$getcatrow['categoryen'];
$showcates=$getcatrow['categoryes'];
echo " <tr>
<td> <input type=\"text\" name=\"<????>\" value=\"$showcaten\"
size=\"18\"/></td>
<td> <input type=\"text\" name=\"<????>\" value=\"$showcat\"
size=\"18\"/></td>
<td> <input type=\"text\" name=\"<????>\" value=\"$showcates\"
size=\"18\"/></td>
</tr>
";
}
echo "
</tr>
</tbody>
</table>
<br /><input type=\"submit\" name=\"update\" value=\"update\" /></form>
";
thanx in advance
Pat
