IntlDateFormatter::parse()

datefmt_parse

(PHP 5 >= 5.3.0, PHP 7, PECL intl >= 1.0.0)

Parse string to a timestamp value

说明

面向对象风格
publicIntlDateFormatter::parse(string $value[,int &$position]): int

过程化风格
datefmt_parse(IntlDateFormatter$fmt,string $value[,int &$position]): int

Converts string $value to an incremental time value, starting at $parse_pos and consuming as much of the input value as possible.

参数

$fmt

The formatter resource

$value

string to convert to a time

$position

Position at which to start the parsing in $value(zero-based). If no error occurs before $value is consumed,$parse_pos will contain -1 otherwise it will contain the position at which parsing ended(and the error occurred). This variable will contain the end position if the parse fails. If $parse_pos > strlen($value), the parse fails immediately.

返回值

timestamp parsed value, or FALSE if value can't be parsed.

范例

OO example

<?php
$fmt = new IntlDateFormatter(
    'en_US',
    IntlDateFormatter::FULL,
    IntlDateFormatter::FULL,
    'America/Los_Angeles',
    IntlDateFormatter::GREGORIAN
);
echo 'First parsed output is ' . $fmt->parse('Wednesday, December 20, 1989 4:00:00 PM PT');
$fmt = new IntlDateFormatter(
    'de-DE',
    IntlDateFormatter::FULL,
    IntlDateFormatter::FULL,
    'America/Los_Angeles',
    IntlDateFormatter::GREGORIAN
);
?>

datefmt_parse() example

<?php
$fmt = datefmt_create(
    'en_US',
    IntlDateFormatter::FULL,
    IntlDateFormatter::FULL,
    'America/Los_Angeles',
    IntlDateFormatter::GREGORIAN
);
echo 'First parsed output is ' . datefmt_parse($fmt, 'Wednesday, December 20, 1989 4:00:00 PM PT');
$fmt = datefmt_create(
    'de-DE',
    IntlDateFormatter::FULL,
    IntlDateFormatter::FULL,
    'America/Los_Angeles',
    IntlDateFormatter::GREGORIAN
);
echo 'Second parsed output is ' . datefmt_parse($fmt, 'Mittwoch, 20. Dezember 1989 16:00 Uhr GMT-08:00');
?

以上例程会输出：

First parsed output is 630201600
Second parsed output is 630201600

参见

• datefmt_create() Create a date formatter
• datefmt_format() Format the date/time value as a string
• datefmt_localtime() Parse string to a field-based time value
• datefmt_get_error_code() Get the error code from last operation
• datefmt_get_error_message() Get the error text from the last operation

Please note:
* on a 32-bit system, parse() will return float if the value gets out of integer range
* while parse() parses fractional seconds with a format like 'yyyy-MM-dd HH:mm:ss.SSSSSS', it only returns an int. This is also true when the value is returned as float, msecs remain absent in the return value.
