datefmt_is_lenient() example
<?php $fmt = datefmt_create( 'en_US', IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'America/Los_Angeles', IntlDateFormatter::GREGORIAN, 'dd/mm/yyyy' ); echo 'lenient of the formatter is : '; if ($fmt->isLenient()) { echo 'TRUE'; } else { echo 'FALSE'; } datefmt_parse($fmt, '35/13/1971'); echo "\n Trying to do parse('35/13/1971').\nResult is : " . datefmt_parse($fmt, '35/13/1971'); if (intl_get_error_code() != 0) { echo "\nError_msg is : " . intl_get_error_message(); echo "\nError_code is : " . intl_get_error_code(); } datefmt_set_lenient($fmt,false); echo 'Now lenient of the formatter is : '; if ($fmt->isLenient()) { echo 'TRUE'; } else { echo 'FALSE'; } datefmt_parse($fmt, '35/13/1971'); echo "\n Trying to do parse('35/13/1971').Result is : " . datefmt_parse($fmt, '35/13/1971'); if (intl_get_error_code() != 0) { echo "\nError_msg is : " . intl_get_error_message(); echo "\nError_code is : " . intl_get_error_code(); } ?>
OO example
<?php $fmt = new IntlDateFormatter( 'en_US', IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'America/Los_Angeles', IntlDateFormatter::GREGORIAN, "dd/mm/yyyy" ); echo "lenient of the formatter is : "; if ($fmt->isLenient()) { echo 'TRUE'; } else { echo 'FALSE'; } $fmt->parse('35/13/1971'); echo "\n Trying to do parse('35/13/1971').\nResult is : " . $fmt->parse('35/13/1971'); if (intl_get_error_code() != 0){ echo "\nError_msg is : " . intl_get_error_message(); echo "\nError_code is : " . intl_get_error_code(); } $fmt->setLenient(FALSE); echo 'Now lenient of the formatter is : '; if ($fmt->isLenient()) { echo 'TRUE'; } else { echo 'FALSE'; } $fmt->parse('35/13/1971'); echo "\n Trying to do parse('35/13/1971').\nResult is : " . $fmt->parse('35/13/1971'); if (intl_get_error_code() != 0) { echo "\nError_msg is : " . intl_get_error_message(); echo "\nError_code is : " . intl_get_error_code(); } ?>
以上例程会输出:
lenient of the formatter is : TRUE Trying to do parse('35/13/1971'). Result is : -2147483 Now lenient of the formatter is : FALSE Trying to do parse('35/13/1971'). Result is : Error_msg is : Date parsing failed: U_PARSE_ERROR Error_code is : 9
