Okay, Shakespeare... 2B || !2B is an example of what we were talking about. As to Shakespeare spelling his name consistently, I can't comment. But there is a story where Shakespeare assisted in the translation of the King James version of the Bible. Shakespeare was born in 1564 and supposedly worked on the Bible when he was 46 years old. The Bible was published one year later in 1611. In King James version of the Bible one can go to the 46th Psalm and count 46 words from the beginning and find the work Shake. Similarly, one can count 46 words forward from the end of the 46 Psalm and find the word Spear. For proof of the word count, here's a link (count for yourself): http://bartelby.org/108/19/46.html Was this Shakespeare's addition or a coincidence? It's probably a coincidence for I find it highly unlikely that Shakespeare influenced the writing of the Bible, but I find it interesting speculation.

Re: [PHP] Generic decorators and type hinting
Is there another way to cleanly wrap method calls for timing/logging purposes? I have a possibly-evil idea that gets around type-hinting by dynamically declaring decorator classes as children of the real classes that need to be timed. You end up with as many decorators as you have classes that need to be timed, but if this is for dev/QA purposes only, that might not be a problem. This method can't have the conceptual simplicity of yours, unfortunately, because __call() will never be invoked in a child class. The original parent's methods will just be called instead. But you can still override the parent's methods with wrapper methods in the child class. I've got some sample code written that first calls get_class_methods() to list the names of all the visible methods of the parent object, then constructs code to declare a child class that overrides those methods with wrapper methods, and finally eval()s the declaration and instantiates an object of the new class. The basic concept seems to work and to get along fine with type-hinting. I'm happy to share the test code if you're interested. Not sure how it would end up working in real life, and I'm guessing there are more sophisticated ways to achieve the same concept, perhaps using the Reflection API. I suspect it also needs some refining to handle protected methods. But it might be a start. Ben -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You don't even need to do that; it'd generate way too much redundant
code. Instead, just use interfaces. The only real downside is that
all the classes you want to decorate would need to implement them and
that would cause a wee bit of ugliness in the code/class declaration.
But if you are fine with that, it's a perfect solution, particularly
since you can type hint interfaces.
interface iDecorator {}
class Thing implements iDecorator {}
class Timer
{
public static function time( iDecorator $obj ) {}
}
$obj = new Thing();
Timer::time( $obj ); // $obj becomes a Timer obj with $obj inside it
$obj-thingMethod(); // Timer passes call to Timer-obj

The primary thing you need to do to make a class a singleton is
disallow the instantiation of a class directly. Which means using
visibility, which is conspicuously absent from your example above.
So, to prevent normal instantiation, we make the constructor private.
Also, we need a method to retrieve the instance. Static members serve
this purpose:
class Singleton {
private static $instance;
private function __construct() { }
public static function getInstance() {
if( ! self::$instance instanceof Singleton) //replace Singleton
with class name
self::$instance = new Singleton; //replace Singleton with class name
return self::$instance;
}
public function __clone() {
throw new Exception('Cannot clone a Singleton');
}
}
This class shell will prevent people from instantiating it ($foo =
new Singleton is an error). Instead, deployment will look like `$foo
= Singleton::getInstance()` which, as you can tell, always returns the
same instance. Throwing an exception out of __clone() will prevent
something like `$foo = Singleton::getInstance(); $bar = clone $foo;`
which is something I see overlooked a lot.
So, if you wanted to convert your full class to a singleton it would
look something like:
class config {
private static $instance;
private static $cfg;
private function __construct() {
if(!is_array(self::$cfg)) {
if(defined('CFGFILE')) {
include(CFGFILE);
self::$cfg = $config;
} else {
self::$cfg = array();
}
}
}
public function getInstance() {
if(!(self::$instance instanceof config)) {
self::$instance = new config();
}
return self::$instance;
}
public function __clone() {
throw new Exception(Cannot clone a Singleton.);
}
public function item($index) {
if(array_key_exists($index, self::$cfg))
return self::$cfg[$index];
else
return null;

Re: [PHP] Generic decorators and type hinting
code. Instead, just use interfaces. The only real downside is that all the classes you want to decorate would need to implement them and that would cause a wee bit of ugliness in the code/class declaration. Can you explain a bit more? As I understood the OP, the challenge was to take a large, already-built code base that relies on Zend Framework (which itself has 1600 classes), and wrap arbitrary existing methods with timing logic -- without significant code changes. As I understand your solution, it would require all pre-existing classes to be modified to implement the iDecorator interface -- and even then, pre-existing methods in those pre-existing classes would not actually be affected. So those would have to be modified also. But maybe I'm totally missing something? Ben -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks for reply, but I want to:
unset($ARR['a']['b'])
Imagine I have this:
$KEYS = array('a', 'b', 'c');
And I want to:
unset($ARR['a']['b']['c'])
It's probably impossible, unless I do something dirty like this:
list($rootA, $rootB, $rootC) = $KEYS;
if (isset($rootC)) unset($x[$rootA][$rootB][$rootC]);
elseif (isset($rootB)) unset($x[$rootA][$rootB]);
elseif (isset($rootA)) unset($x[$rootA]);

This is possible. You're just not giving enough consideration to your
exit strategy :)

RE: [PHP] Converting URL's to hyperlinks.
Maybe I misunderstood the OP, but wouldn't this (or something like it) be

Throw any random web site to an HTML validator

The correct solution is of course:
$u = htmlspecialchars ($url);

Instead this:

unset($array);
This:
unset($array[$final]);

[PHP] Searching on AlphaNumeric Content Only
Is there is a way to search only for the alphanumeric content of field in a db? I have an itemID field that contains item #'s that include dashes, forward slashes, etc, and I want people to be able to search for an item # even if they don't enter the punctuation exactly. Here's an example: let's say there is an itemID of 4D-2448-7PS but someone omits the dashes and searches on 4D24487PS. Is it possible in PHP to have the find be successful, even if the search criteria doesn't exactly match what's stored in the field? If this is possible, I'd appreciate it if someone could just point me in the right direction so I can read up on it.

Re: [PHP] Searching on AlphaNumeric Content Only
Hi,
It's definitely possible to do when you do it in PHP, but not sure about on
the database side. You could read all records into memory and then iterate
over it with something like:
$toSearch = 4D24487PS
$charsToIgnore = array('-','+',...);
foreach ($items as $k=$item) {
$itemVal = str_replace($charsToIgnore, '', $item);
if (strcmp(str_replace($charsToIgnore, '', $toSearch), $itemVal) == 0) {
$return = $item;
break;
}
}
This however might use a lot of memory, but if your DB is a manageable size
it should be ok. You can probably optimise it by iterating over a db result
set instead of reading everything into an array.
Cheers,
Tim

I have an itemID field that contains item #'s that include dashes, forward slashes, etc, and I want people to be able to search for an item # even if they don't enter the punctuation exactly. Not sure if there's anything specifically PHP-ish that will help you here, but I would be inclined to start by storing a stripped-down version of the item ID (alphanumeric characters only) in a separate column in the database table. Then, when a user enters some search data, I would remove non-alphanumeric characters, if any, from the user's input, and then search the stripped column with this normalized version of the input. If you want even fuzzier matching (inadvertent transpositions or an omitted character or two OK, for example), you might read about Levenshtein distance: http://en.wikipedia.org/wiki/Levenshtein_distance PHP has a levenshtein function but you'll have to figure out a way to use it efficiently with your data set. Or, if Levenshtein isn't quite right for your needs, the article above might at least point you in a useful direction.
