im guessing those are newline characters in windows format that arent
getting interpreted correctly on the
client side. you might try stripping out the newline characters prior to
encoding the data.
$jsonOut = json_encode(utf8_encode(str_replace("\r\n", '',
$stringToEncode)));
also, what are you trying to encode? if you are encoding arrays or objects
(php that is) you will have to
utf8_encode all the elements of those complex datums prior to handing them
to json_encode() for
the final output.

Hi everybody!
I'm building a small ajax app which consists of only 3 php files.
index.php which contains all the app and has a couple of
links. When a
link is clicked an Ajax request is sent to the server (using
prototype)
to the
url central.php with only one parameter 'id'. Depending on that
parameter, central.php should look for the appropiate
content, in this
case link1.php.
Then I return a JSON object with the "things" that should be
updated on
index.php
So this is the pseudo-code:
index.php
<html>...
<body>
<a href="" onclick="[send the Ajax request using prototype
with the id =
1]>Link #1</a>
<div id="theUpdatableDIV"></div>
</body>
central.php
<html>...
<body>
<?php
[read the id parameter]
switch(id){
case 1: //which is the only case for now!!
//build the JSON object
$output = array("title" => "Link #1 Title!",
"content"=>file_get_contents("link1.php"));//here I read the
last file
which has the content to be updated asynchronously
return [the JSON object based on $output];
break;
}
?>
</body>
link1.php
<div>Welcome to the content of link #1 which was updated using <a
href=" ajax.org <http://ajax.org>">ajax</a></div>
the JSON object is formed ok, now, my problem is that
link1.php outputs
like this:
<div>Welcome to the content of link #1 which was updated
using <a
href="ajax.org <http://ajax.org>">ajax<\/a><\/div>
So at the moment I update the <div id="theUpdatableDIV">
element on
index.php, I get no "real" content, but a string with the
strange slashes.
I've tried:
stripslashes, ereg_replace, str_replace and strtr to
eliminate the
wierd slashes.
Can anybody tell how to do it right?
how are you building the json object?
i recommend
json_encode(utf8_encode($dataToEncode));
if youre using php5. if youre using php4, try this:
http://mike.teczno.com/JSON/JSON.phps
also, you might want to check out firebug for firefox. it will
let you
easily analyze the interaction between the client and server.
also, to verify that the json object youre generating is infact ok;
run it through here:
http://www.jslint.com/
-nathan
Hi Nathan,
I'm using php5, and I'm building the JSON object just like that,
with the json_encode.
The problem with using utf_encode apart from the original is that
I get the \n\r for each line in the file read.
Any suggestions?
Thanx
are you running windows?
im guessing those are newline characters in windows format that arent
getting interpreted correctly on the
client side. you might try stripping out the newline characters prior
to encoding the data.
$jsonOut = json_encode(utf8_encode(str_replace("\r\n", '',
$stringToEncode)));
also, what are you trying to encode? if you are encoding arrays or
objects (php that is) you will have to
utf8_encode all the elements of those complex datums prior to handing

-nathan
Hi again Nathan,
well I actually did that before, using the str_replace to eliminate al
the windows \r\n, but the big problem isn't that
the HTML code is being escaped too.
I get something like <div>this is the content<\/div>
it seems like the '/' is being escaped, but I need it as HTML.

how are you using the json object on the client-side after its sent by the
server?
below is a json snippet from an application of mine, many of the tags look
the same
as what youve shown (because theyve been encoded the same way).
ive have not encountered the problem you have, that is, the escape
characters do
not pass though when i splice them into the DOM.
im using the same encoding technique i recommended within PHP. on the
client side
i instantiate the json object as follows:
var htmlUpdates = eval("(" + transport.responseText + ")");
if you use a string directly on the client side, the escape characters will
pass
through, however, if you run it through eval(), the escape characters will
be stipped
out by the javascript interpreter. im not sure whats going on, but im
starting to think
its something on the client side..

As previously posted, you need to work with your mail server admin.
sendmail is not normally on WinDoze boxes, so do some googling for the
setup you have, and talk with your admins to see what you need to do to
get it set up to work correctly.

If I had to venture a guess, you nested 100 functions (called 100 functions in
a stack), and therefore reached the maximum limit in PHP. That is, you
overflowed the stack. You may have a recursion problem, especially if you're
using an XML parser that is not the PHP 5-native one.

since when is there an arbitrary maximum recursion limit???

thats you think, personally I test this kind of thing when Im
not sure:
php -r 'function foo() { static $x = 1; echo "foo ", $x++, "\n"; foo(); }
foo();'
which proves quite adequately that there is no function recursion limit as such,
and that the error message is simply 'Segmentation Fault' as opposed to some
message
about recursion limit being reached.
therefore the recursion limit, whether in defined in php source or in user land
code
is something specific to the XML extension/code the OP was using.

Running your code shows that there is a limit. Although it doesn't throw an
error.
It just stops after n recursive calls:
php4 recursive calls: 796
php5 recursive calls: 49841
php6 recursive calls: 6007

A. this is not the output of the script
B. do you think these numbers are the same for everyone?
heck they're not even garanteed to be the same between 2 runs
on the same machine with the same php binary.
C. it doesn't just stop, a segmentation fault occurs.
e.g.:
last 2 lines of output for 4.3.10-19:
foo 11137
foo Segmentatie fout
last 2 lines of output for 4.3.10-19:
foo 11147
foo Segmentatie fout
last 2 lines of output for 5.1.1:
foo 37435
foo Segmentation fault
last 2 lines of output for 5.1.1:
foo 37436
foo Segmentation fault
last 2 lines of output for 5.1.2:
foo 30795
foo Segmentatie fout
last 2 lines of output for 5.1.2:
foo 30787
foo Segmentatie fout
Therfore there is NO recursion limit in php (not withstanding a specific limit
in functions belonging to an XML extention). the percieved limit is php running
out of memory ... as long as there is memory php will continue to recurse.

Hello everybody,
I am trying to get googiespell running but it looks like I
do need PHP5 installed with pspell. Am I right?
The doc's on the site are not clear about this. I am currently running
php 4.x The doc page lists GSpellerServer, but it makes the impression
that this is optional.

Hi,
just found the problem. PHP has to be compile with ssl. I am using a

to redeclare the inner functions, which will generate an error."
So, as you're not calling salestax() anywhere, the convert_pound function
isn't defined.
I wasn't aware of nested functions before your question, but reading the
above on how the declaring function can only be called once, I feel they are
best avoided. Does anyone have anyone have any examples where using them
would be beneficial?

Ok.If I use the code below :
<?php
function salestax($price,$tax) {
function convert_pound($dollars, $conversion=1.6) {
return $dollars * $conversion;
}
$total = $price + ($price * $tax);
echo "Total cost in dollars: $total. Cost in British pounds: "
.convert_pound($total);
}
salestax(15.00,.075);
echo convert_pound(15);
?>
I get no errors but I still get only the 1st line executed.

Ok.It was simply an oversight from my side.If I put a <br /> I get the
two results clearly.Here is the clearer code :
<?php
function salestax($price,$tax) {
function convert_pound($dollars, $conversion=1.6) {
return $dollars * $conversion;
}
$total = $price + ($price * $tax);
echo "Total cost in dollars: $total. Cost in British pounds: "
.convert_pound($total);
}
salestax(15.00,.075);
echo "<br />" . convert_pound(15);
?>

That's still pretty nasty though:
<?php
<snip>
salestax(15.00,.075);
salestax(15.00,.075);
?>
gives:
Total cost in dollars: 16.125. Cost in British pounds: 25.8
24
Fatal error: Cannot redeclare convert_pound() ...
What's wrong with non-nested functions? i.e.:
function convert_pound($dollars, $conversion=1.6) {
return $dollars * $conversion;
}
function salestax($price,$tax) {
$total = $price + ($price * $tax);
echo "Total cost in dollars: $total. Cost in British pounds: "
.convert_pound($total);
}

That may be so, but this is a PHP mailing list. I don't mean to sound
harsh, but if you need help configuring a mail server this is not the
place to find it.

The SMTP server you are using is not configured to allow the machine
you're running PHP on to send mail. This is not a PHP problem - speak
to your mail server administrator.

This is wonderful to know! Is this documented in the PHP manual (if so,
where), or are you just brilliant? =D

I am on a Win2k3 server running PHP5 (manual install) and IIS6. I've

to the php5isapi.dll in IIS. I'm assuming b/c I do this that I am using

You're not running any exe file. IIS uses php5isapi.dll instead of an
exe file - they essentially do the same job but the dll is designed to
be loaded into another application.

I don't know if this is detailed in the manual - I just know a bit about
how Windows and PHP work.
As for my brilliance, I'm not qualified to comment.

first you read lots about php and programming, whilst your doing that
you you try out lots of code to see what it does ... eventually your
understanding gets to a level where you are capable of writing some code
to do something you want.
easy really.
this mailing list is not here to turn whatever idea you happen
to have today into working code.
