PHP-HEXからEBCDICへの変換

Question

Hexの値をPHPのEBCDICに変換するにはどうすればよいですか？

これを行う最も実際的な方法は何ですか？

Hex : 313233343536373832313332333435 
Ascii: 123456782132345 

使用することにより：

hex2bin($foo); 

Answer 1

の場合）（あなたの `HEX2BIN後`）（ `ascii2ebcdicで試してみて、`、私達に私に教え

function ebcdic_to_ascii($ebcdic_hexstring /*expecting something like F0F1....*/)

    return $asciiOut; 

} 

?> 

Answer 2

strtrを使用すると、ASCIIへのマッピングEBCDICを提供する場合、仕事をしなければならない私がこれまでAsciiからhexで何をしたか

。

アルファベット3文字のための例マッピング：

$ebcdicSet = "\x81\x84\xa2"; 
$asciiSet = "ads"; 

$ebcdic = "\x81\xa2\x84\x81\xa2\x84"; // 6 bytes 
$ascii = strtr($ebcdic, $ebcdicSet, $asciiSet); 

echo $ascii; // outputs "asdasd" 

あなたの入力はバイナリ進が、16進数表現で刺されていない場合、あなたはそれを最初にHEX2BINする必要があります。

$ebcdic = "81a28481a284"; // 12 bytes 
$ascii = strtr(hex2bin($ebcdic), $ebcdicSet, $asciiSet); 
echo $ascii; // outputs "asdasd"
