unicode_set_error_mode — Set the error mode for strings conversions
说明
bool unicode_set_error_mode
( int $direction
, int $mode
)
This function sets the error mode for string conversions between different
encodings. An error can occur during conversion when an illegal character
is encountered or if a character cannot be represented into the new encoding.
By default, when an error is encountered, the conversion stops.
参数

conversions from a unicode string to a binary string
or TO_UNICODE, which will set the error mode
for conversions from a binary string to a unicode string.
-
mode
