IntlDateFormatter::parse -- datefmt_parse — Parse string to a timestamp value

说明

面向对象风格

public IntlDateFormatter::parse(string $string, int &$offset = null): int|float|false

过程化风格

datefmt_parse(IntlDateFormatter $formatter, string $string, int &$offset = null): int|float|false

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

参数

formatter: The formatter resource
string: string to convert to a time
offset: Position at which to start the parsing in string (zero-based). If no error occurs before string is consumed, offset 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 offset > strlen($string), the parse fails immediately.

返回值

Timestamp of parsed value, or false if value cannot be parsed.

示例

示例 #1 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
);
?>

示例 #2 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');
?>

以上示例会输出：

First parsed output is 630201600
Second parsed output is 630201600

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.
