Question

$my_var = "1";

$connection = db2_connect ( "*LOCAL", "ISCSC", "ISCSC" );

$strSql = 'CALL LMTLIB.ARTEST(?)';

$stmt = db2_prepare ( $connection, $strSql );

db2_bind_param($stmt, 1, "my_var", DB2_PARAM_INOUT, DB2_CHAR);

$rc = db2_execute ( $stmt );

echo $my_var;

执行此代码块时，$ my_var的值为|-|

正在调用的测试RPGLE程序正在返回哇

当程序被更改时，我回来的字符是不同的...所以我知道我从程序中获取值。唯一的问题是，如何将这些字符从EBCDIC转换为ASCII。

修改

我尝试过使用以下内容：

mb_convert_encoding($my_var, "ASCII", "cp037");
mb_convert_encoding($my_var, "ASCII", "EBCDIC");
iconv("cp037", "ASCII", $my_var);
iconv("EBCDIC", "ASCII", $my_var);

但是我得到了这个错误：“错误的字符集，不允许从”ebcdic“转换为”ascii“”

并且，“错误的字符集，不允许从”cp037转换为ascii“”

Answer 1

这对我们在几个系统上起作用（IBM i v7r1，PHP Version 5.4.16）：

$ ascii_value = iconv（“IBM-1047”，“ISO8859-1”，$ ebcdic_value）; // EBCDIC-＆gt; ASCII转换

Answer 2

使用以下PHP函数：

$recoded = recode_string ('EBCDIC..ASCII', $my_var);

Answer 3

在CREATE PROCEDURE语句中，使用与您的语言匹配的CCSID。对于美国英语，那将是37.例如：

CREATE PROCEDURE buck.phptest(         
 inout parm_inout varchar (5) ccsid 37)
LANGUAGE RPGLE                         
NOT DETERMINISTIC                      
CALLED ON NULL INPUT                   
EXTERNAL NAME buck.phptest             
PARAMETER STYLE GENERAL

Answer 4

内置函数EBCDIC到ASCII

我必须在窗口环境中执行此操作

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

        //need to delcare it to avoid warning
