apd_set_socket_session_trace
Since Apache 1 & 2 use diffrent methods (Unicode vs. UTF8) on Win32 platforms to encode urls, i've implemented the following workaround to get around this "bug" (which is actually known behaviour and wont get fixed). This workaround is really usefull when writing PHP scripts which have to work on all platforms (Windows, Linux, BSD etc.), must process URLs and must work under both Apache versions.
<?php
$httpd = explode(' ', $_SERVER['SERVER_SOFTWARE']);
if(substr($httpd[0], 0, 6)=='Apache' && substr($httpd[0], 7, 1)==2 && $httpd[1]=='(Win32)')
{
if(isset($_SERVER['REQUEST_URI'])) $_SERVER['REQUEST_URI'] = str_replace('%2F', '/', rawurlencode(utf8_decode(rawurldecode($_SERVER['REQUEST_URI']))));
if(isset($_SERVER['REDIRECT_URL'])) $_SERVER['REDIRECT_URL'] = str_replace('%2F', '/', rawurlencode(utf8_decode(rawurldecode($_SERVER['REDIRECT_URL']))));
override_function('urlencode', '$url', 'return str_replace("%2F", "/", rawurlencode(utf8_encode($url)));');
}
?>
override_function
(PECL apd:0.2-1.0.1)
override_function — 組み込みの関数を上書きする
説明
bool override_function
( string $function_name
, string $function_args
, string $function_code
)
シンボルテーブルを書き換えることで、組み込みの関数を上書きします
パラメータ
- function_name
-
上書きする関数。
- function_args
-
関数への引数をカンマ区切りの文字列で指定します。
通常は、このパラメータだけでなく function_code パラメータも (シングルクォート区切りの文字列で) 指定することでしょう。シングルクォートで囲んだ文字列を使用する理由は、 変数名がパースされないようにするためです。 ダブルクォートを使用するなら、変数名をエスケープして \$your_var のようにしなければなりません。
- function_code
-
関数の新しいコード。
返り値
成功した場合に TRUE を、失敗した場合に FALSE を返します。
例
例1 override_function() の例
<?php
override_function('test', '$a,$b', 'echo "DOING TEST"; return $a * $b;');
?>

I thought the example was not very helpful, because it doesn't even override the function with another function.
My question was: If I override a function, can I call the ORIGINAL function within the OVERRIDING function?
ie, can I do this:
<?php
override_function('strlen', '$string', 'return override_strlen($string);');
function override_strlen($string){
return strlen($string);
}
?>
The answer: NO, you will get a segfault.
HOWEVER, if you use rename_function to rename the original function to a third name, then call the third name in the OVERRIDING function, you will get the desired effect:
<?php
rename_function('strlen', 'new_strlen');
override_function('strlen', '$string', 'return override_strlen($string);');
function override_strlen($string){
return new_strlen($string);
}
?>
I plan to use this functionality to generate log reports every time a function is called, with the parameters, time, result, etc... So to wrap a function in logging, that was what I had to do.
