    过程化风格

    datefmt_set_lenient(IntlDateFormatter$formatter, bool$lenient): void

    Define if the parser is strict or lenient in interpreting inputs that do not match the pattern exactly. Enabling lenient parsing allows the parser to accept otherwise flawed date or time patterns, parsing as much as possible to obtain a value. Extra space, unrecognized tokens, or invalid values ("February 30th") are not accepted.

    参数

    formatter

    The formatter resource

    lenient

    Sets whether the parser is lenient or not, default is true (lenient).

    返回值

    成功时返回 true， 或者在失败时返回 false。

    示例

    示例 #1 datefmt_set_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     "\nNow lenient of the formatter is : ";
    if (    $fmt->isLenient()) {
    echo     'TRUE';
    } else {
    echo     'FALSE';
    }
    datefmt_parse($fmt, '35/13/1971');
    echo     "\nTrying 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();
    }

    ?>

    示例 #2 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     "\nNow 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();
    }

    ?>

    以上示例会输出：

    lenient of the formatter is : TRUE Trying to do parse('35/13/1971'). Result is : 66038400 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
