odbc_binmode — Handling of binary column data
$result_id
   , int $mode
   )Enables handling of binary column data. ODBC SQL types affected are BINARY, VARBINARY, and LONGVARBINARY.
When binary SQL data is converted to character C data, each byte (8 bits) of source data is represented as two ASCII characters. These characters are the ASCII character representation of the number in its hexadecimal form. For example, a binary 00000001 is converted to "01" and a binary 11111111 is converted to "FF".
| binmode | longreadlen | result | 
|---|---|---|
| ODBC_BINMODE_PASSTHRU | 0 | passthru | 
| ODBC_BINMODE_RETURN | 0 | passthru | 
| ODBC_BINMODE_CONVERT | 0 | passthru | 
| ODBC_BINMODE_PASSTHRU | 0 | passthru | 
| ODBC_BINMODE_PASSTHRU | >0 | passthru | 
| ODBC_BINMODE_RETURN | >0 | return as is | 
| ODBC_BINMODE_CONVERT | >0 | return as char | 
If odbc_fetch_into() is used, passthru means that an empty string is returned for these columns.
result_idThe result identifier.
       If result_id is 0, the
       settings apply as default for new results.
       
Note: Default for longreadlen is 4096 and
modedefaults to ODBC_BINMODE_RETURN. Handling of binary long columns is also affected by odbc_longreadlen().
mode
       Possible values for mode are:
       
ODBC_BINMODE_PASSTHRU: Passthru BINARY data
         
        ODBC_BINMODE_RETURN: Return as is
         
        ODBC_BINMODE_CONVERT: Convert to char and return
         
        
   Returns TRUE on success or FALSE on failure.
