IntlDateFormatter::parse -- datefmt_parse — Parse string to a timestamp value
面向对象风格
$string, int &$offset = null): int|float|false
过程化风格
Converts string to an incremental time value, starting at
offset and consuming as much of the input value as possible.
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.
Timestamp of parsed value, or false if value cannot be parsed.
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');
?>
以上例程会输出：
First parsed output is 630201600 Second parsed output is 630201600
