Converts string to an incremental time value, starting at
offset and consuming as much of the input value as possible.
formatterThe formatter resource
stringstring 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.
Example #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
);
?>
Example #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
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.
