Re: [PHP-DEV] SSL streams switching to blocking socket
I found same problem in IIS recently.
When SSL connection established and read to eof,I can't write anything
to stream again.
It's trow :SSL operation failed with code 1. OpenSSL Error messages:
error:140D00CF:SSL routines:func(208):reason(207).
My php version is 5.2.9

[PHP-DEV] any solution about array_walk with pass-by-reference UseData?
In Online Document say's:
Users may not change the array itself from the callback function. e.g.
Add/delete elements, unset elements, etc. If the array that
array_walk() is applied to is changed, the behavior of this function
is undefined, and unpredictable.
So I'm use Use Optional param( [, mixed $userdata ])
here is my code
$return=array();
$disable_full=array('a','b','c');
$disable_start=array('_','!','HTTP'/*,'ddd','ddd','ddd','ddd','ddd'*/);
$check_array=array("a"=>1,"_POST"=>'c',"HTTP"=>"f","ddd"=>array('fefe'));
array_walk($check_array,'walk_fun_with_foreach',&$return);
print_r($return);
function walk_fun_with_foreach(&$source,$key,$return){
global $disable_full,$disable_start;
//var_dump($key);
if(is_array($source)){
array_walk($source,'walk_fun_with_foreach',&$return);
}else{
if(in_array(strval($key),$disable_full)){
//exit;
return;
}else{
foreach($disable_start as $key1 => $value){
if(strpos($key,$value)===0){
//echo $key;
return;
}
}
}
//echo $key;
$return[$key]=$source;
}
}
==
it's print :
Array ( [0] => fefe )
but in version php5.2.x and higher version,display Warning message:
Warning: Call-time pass-by-reference has been deprecated in
If I'm change
array_walk($check_array,'walk_fun_with_foreach',&$return);
to
array_walk($check_array,'walk_fun_with_foreach',$return);
and
declare function like
function walk_fun_with_foreach(&$source,$key,&$return)
no Warning Display
But result is not my needed.
Anyone has solution about is?I'm don't like use foreach for
instead,beacuse of some preformance reason.
