[PHP] PHP Source File Encoding
Gotta a question whose answer should be really obvious to me but, for some reason, is just eluding me. Which encodings can PHP handle for source files? I've been using iso-8859-1 but what about utf-8? Thanks, C Drozdowski -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Including class of Exception in exception message
I'm using Exceptions and variously handling them in try..catch blocks or defaulting to my set_exception_handler handler. When I create an Exception I'd like to prepend the class of the Exception to the message. Can this be done with code or do I have to hard code the name of the Exception class into the message every time I throw the exception? For Example: I'd like to turn this... throw new myException(myException: So this is it, we're going to die); into... throw new myException( CODE . : So this is it, we're going to die); where CODE is some php code that refers to the class of the exception being thrown. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Smart Trimming of UTF-8 Entities for Database
I need to be able to store UTF-8 characters from a form into a MySQL table. But I need to support pre-UTF-8 MySQL ( 4.1). So I'm converting UTF-8 characters into their numeric entities (e.g. ñ = #241;). The problem is that if the user enters a character that gets converted to an entity, the string might end up being longer than the field definition in the table allows. For example, if I have a varchar(5) column and try to insert señor (which has been converted to sen#241;or), I get sen# in the table which is useless. Has anyone dealt with this and if so how? Thanks in advance for any advice, or pointers to any code that deals with this. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Why do I have to declare __set if I declare __get for read-only properties?
Howdy,
I'd like to access some of the private members of my classes as
read-only properties without resorting to function calls to access
them. (e.g. $testClass-privateMember instead of
$testClass-privateMember(), etc)
Based on my research and testing, using the __get and __set overloading
methods appears to be the only way to do so. It also, based on testing,
appears that these private members must be in an array.
What I do not understand is that if I declare a __get method I MUST
also declare a do nothing __set method to prevent the read-only
properties from being modified in code that uses the class.
For example, the code below allows me to have read-only properties.
However, if I remove the do nothing __set method completely, then the
properties are no longer read-only.
I'm curious as to why I HAVE to implement the __set method?
Example:
?php
class testClass
{
private $varArray = array('one'='ONE', 'two'='TWO');
public function __get($name)
{
if (array_key_exists($name, $this-varArray)) {
return $this-varArray[$name];
}
}
public function __set($name, $value)
{
}
}
$test = new testClass();
$test-one = 'TWO'; // doesn't work
echo $test-one; // echo s 'ONE'
?

[PHP] Using header(0 to manage user inactivity
I'd like to be able to timeout a user if they are inactive for X
minutes. Say, if they walk away from the browser leaving sensivive data
in plain view.
Is there any reason that using the header() function as below wouldn't
be a reliable way to do this (albeit user-unfriendly)? It works for
me on my Mac with various browsers, but I wonder how universally it
will work.
$timeout = 900; // 15 minutes
header('Refresh: ' . $timeout . ';url=www.whatever.com/logout.php');

[PHP] Re: mySQL outputting XML
There is a pear package that does this: XML_sql2xml. It's at: http://pear.php.net/package-info.php?pacid=18 There is more info at: http://php.chregu.tv/sql2xml/ It's pretty flexible.

[PHP] Borrowed code- how to give credit
Hey, I used a single line of code (ver batim) from a pear class in my own code. I try to always be honest and not steal code but this single line does exactly what I need. The code is for a NPO website and will never be sold or anything like that. How should I give credit for the line of code in my own code? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] PHP 5 DOM, XPath, UTF-8, and Form Input
I have been doing some testing and need confirmation that the following is correct. You have a DOMDocument that potentially contains UTF-8 encoded data (it might not however). You want to search it via DOMXpath-query() using a value that comes from a $_POST value. If the page that posts the data via a form to the search script IS NOT encoded in UTF-8, then the value must be converted to UTF-8 before it is used in the query expression. Else, if the posting page IS UTF-8 encoded, then the $_POST data does not need to be converted before being used in the expression. Is this correct? Also, if the $_POST data comes from a UTF-8 encoded page, and it needs to be sanitized before use, will the basic PHP string functions work on the data (e.g. htmlentities, stripslashes, trim, preg_replace, etc)? If not what do I have to do? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] XPath Query Exressions and Quote Characters
I've got a problem with quote characters and building XPath query expressions (PHP 5.0.3). What do I need to do to get them to work? I've tried various encoding functions but cannot figure it out. Given this expression, if $id contains one or more double quotes, an error is thrown. $query = '//book/chapter' . '[EMAIL PROTECTED]:id=' . $id . ']'; Given this expression, if $id contains one or more single quotes, an error is thrown. $query = //book/[EMAIL PROTECTED]:id='$id']; I need to be able to build an exression that contains either double or single quotes in the search regarding of how I programatically build the expression. Any insight would be appreciated. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: XPath Query Exressions and Quote Characters
It's just a coincidence that I used xml:id as part of my query
expression. If I use following code method to build my expression:
$query = '//book/chapter[section=' . $section . ']';
or say
$query = '//book/[EMAIL PROTECTED]' . $title . ']';
I get an Invalid Predicate... error when either the $section or
$title variable contains a double quote.
However, here's an example:
XML:
?xml version=1.0 encoding=UTF-8?
table
row
mod_idhome/mod_id
mod_access1/mod_access
mod_nameHome/mod_name
/row
/table
XPath Expression:
$query = '//table/row[mod_name=' . $name . ']';
Variable Assignment:
$name = utf_encode('Home');
Using the expression throws the Invalid Predicate Error.

First of all check the XPath documentation:
http://www.w3.org/TR/xpath
http://www.w3.org/TR/xpath#path-abbrev
AFAIK your expression above is the way to build this query. Give us a
link to the XML doc if you want us to take a look at that specific doc.
Also make sure you referenced the correct DTD. And (just to be sure)
try to validate you document against the DTD.
Given this expression, if $id contains one or more single quotes, an
error is thrown.
$query = //book/[EMAIL PROTECTED]:id='$id'];
I need to be able to build an exression that contains either double or
single quotes in the search regarding of how I programatically build the
expression.
A couple of things that may be in play here...
- First of all I recall there was a specific bug with xml:id, although I
can't recall off the top of my head what it was...
- Secondly the XPath querying interface in PHP will only return simple
data at this point. In fact, I think it will only return strings.
http://www.w3.org/TR/xpath#attribute-nodes
But if your ID is simple data (integer / string), I can't imagine it
would be a problem for XPath to return it.
