[PHP-DEV] XOR congruentation breaks PHP
Hey Folks!
I've been writing some code for a small project and saw PHP crashing every
time.
The Code:
?php
/*
* XOR buffer v1
*/
class XoRb {
/* Set buffer ( - write genPad to file ) in bit */
public $buffer = 4096;
public function encrypt($InputString, $KeyPhrase){
$KeyPhraseLength = strlen($KeyPhrase);
for ($i = 0, $strlen = strlen($InputString); $i
$strlen; $i++)
$InputString[$i] = chr( (
ord($InputString[$i]) ^ ord( $KeyPhrase[ ( $i % $KeyPhraseLength ) ] ) ) );
return $InputString;
}
public function genPad ( $input ) {
for ( $i = 1, $o = null, $strlen = strlen($input);
$i = $strlen; ++$i )
$o .= chr( mt_rand( 10, 300 ) );
return $o;
}
public function writePad ( $file, $byte, $buffer = false ) {
$fo = fopen( $file, a+);
if ( !$buffer ) $buffer = $this - buffer;
if ( $byte $buffer ) $buffer = $byte;
for ( $i = 1, $o = null; $i = $byte; ++$i ) {
$o .= chr( mt_rand( 10, 300 ) );
if ( strlen( $o ) = $buffer + 20 )
print Writing buffer . chr ( $i %
$buffer ) . \n and fwrite( $fo, $o ) and $o = null;
}
}
}
$xor = new XoRb;
$xor - buffer = 1024;
$xor - writePad ( 'int.dat', 8192 * 1000 );
/* //Interface
while ( true ) {
print Input: ;
$input = trim(fgets(fopen(php://stdin, a+)));
print \tPad: . ($str = $xr-genPad($input));
print \n\tOutput: . $xr-encrypt($input, $str) .
\n\n;
}
*/
?
PHP now breaks at:
chr ( $i % $buffer ) ,
in:
if ( strlen( $o ) = $buffer + 20 ) print Writing buffer . chr ( $i %
$buffer ) . \n and fwrite( $fo, $o ) and $o = null;
while $I = 5k ± 2k.
Tested within CLI on Windows, I don't think, it'll break on Linux, nor
Apple.

Hello Christopher! It crashes now at $i = 40k ± 5k, while ( 5k ~ 0.5 second ). Rather ugly, isn't it ?

Re: [PHP-DEV] casting doubles to ints
Hi Lain! As much as I did understand, this might be a pretty good idea. Anyhow, you want to make this variable to be constant? I think, this might break some calculations.- And another question: Does anyone knows, why PHP is showing 2147483647 as PHP_INT_MAX ? *truly, I'm running x64* Thanks, -- (c) Kenan Sulayman Freelance Designer and Programmer Life's Live Poetry 2009/2/4 Iain Lewis ile...@uk.ibm.com Hello all, I wanted to suggest back porting the behaviour of the DVAL_TO_LVAL macro from zend_operators.h from 5.3 to 5.2, and wondered whether people thought this was a good idea or not? The reason I want to do this is that while writing some tests, I noticed that the behaviour of casting a float to an int is a bit counter-intuitive on 64bit platforms for PHP 5.2. It looks as though this has been fixed in 5.3, and it would seem like a good idea to put this change back to 5.2 as well. From a personal point of view, it would mean I could write one test that would work on both 5.2 and 5.3, but it also seems like a sensible change, as the current behaviour is non-obvious. The change would cause some current tests to break, but I am happy to do the work to fix those up. This is how a few expressions get evaluated at the moment. Changing the macro would make the 5.2 behaviour match 5.3 Expression 5.3 (RHEL5-64) 5.2 (RHEL5-64) (int) (PHP_INT_MAX) 9223372036854775807 9223372036854775807 (int) (PHP_INT_MAX + 1) 9223372036854775807 -9223372036854775808 (int) (PHP_INT_MAX + 1000) 9223372036854775807 -9223372036854775808 (int) (PHP_INT_MAX + 1) 9223372036854775807 -9223372036854765568 Does this seem like a good change? -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DEV] New function proposal: spl_class_vars / params / contents
Thanks, I did propose the function because the construction in user-land is quite expensive; Actually tests showed: the user-land algorithm of mapping these objects (regarding a count of thousand; up to a half million objects / iterations) took 0,2 - 70 seconds to execute! Therefore: I would be very, very gracefully, if someone may implement this thing into the PHP engine.

The way we solved it for FLOW3 is to create a ReflectionService that caches such information as long as the source doesn't change. yeah its a general problem .. but so far the decision has been that we should move away from adding more and more functions/methods for highly specialized cases (as in not continue in the get_class() etc. approach). now speeding up reflections is a very real issue .. suggestions in this regard are quite welcome. maybe offering a cache service as part of core is one approach .. Yes, please. Keep clutter out of the engine especially for stuff which should not be used often. If you are relying on Reflection to be fast for you everyday code then you're IMHO doing something weird and it is ok that you have to write your own caching for it (-:C seems to me that many of the new requests coming in, including my own stupid ones are because people want to build fast decent orm's in php - a definitive list of what one needs to make an orm in php, the userland approaches possible, what could be implemented in php and what couldn't might be good. address the whole thing in a oner. quite sure the requests and need is only going to grow.. imho it's being encouraged by the increasing numbers using PDO - it kind of suggests building an orm :p also, very unlike me, but a service to cache reflection classes is quick and simple to implement in userland - (although if there is a free speed up to reflection going I'll 'ave some) -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] New function proposal: spl_class_vars / params / contents
Hi,
I'd like to propose a new function: spl_class_vars / params / contents.
Notice: I haven't figured out a name yet Please help me find one.. :-)
The function returns an array of the contents of the given class-object.
The class-object parameter may be text or rather directly the object ( new
foo() ).
Example, while the function-name 'spl_class_contents' is being used :
?php
class foo {
public $data = array();
public $lastbit = null;
public $passive = null;
public static $bar = null;
public $foo = true;
public function registerCall ( $key, $call, $passive =
false ) {
return $this -foo;
}
private static function bregisterCall ( $key, $call,
$passive = false ) {
return $this -foo;
}
}
print_r ( spl_class_contents( 'foo' ) );
print_r ( spl_class_contents( new foo() ) );
?
Expected
Ex. 1:
?php
print_r ( spl_class_contents( 'foo' ) );
?
should return the following array: ( print_r 'd, cause the returning value
should be usable for other functions )
Array
(
[data] = Array
(
[0] = public
[1] = array
)
[lastbit] = Array
(
[0] = public
[1] = null
)
[passive] = Array
(
[0] = static
[1] = null
)
[foo] = Array
(
[0] = public
[1] = true
)
[registerCall] = Array
(
[0] = public
[function] = Array
(
[0] = key
[1] = call
[passive] = false
)
)
)
Ex.2.
Example 2 should return the same as the above example.
Cheers,

Par example:
As normally used:

Suggestion:
?
$c = function (~) { ~ }

More Simple, have a better point of view and a bit easier.
