说明
面向对象风格
$value
[, int &$position
] )过程化风格
$fmt
, string $value
[, int &$position
] )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
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' );
