Manual:wfTimestamp/zh
概要
wfTimestamp() (part of GlobalFunctions.php) provides functionality to convert between common timestamp formats, including MediaWiki timestamps, UNIX timestamps, MySQL DATETIME format, RFC 2822 format and more.
有关完整列表，请参阅下面的 格式。
Timestamps will be output without a timezone or in the GMT timezone, as specified by the particular format.
Never use wfTimestamp() when inserting a timestamp into the database. This will break in Postgres and possibly other non-MySQL databases. 改用$dbw->timestamp()
用法
wfTimestamp( $output_format, $timestamp )
- Returns a timestamp of type string in the format specified by the
$output_formatargument. - Throws
MWExceptionif an incorrect formats is passed via the$output_formatargument. - Returns
falseif an invalid or unrecognized timestamp is passed via the$timestampargument.
| 参数 | 默认 | 注释 |
|---|---|---|
$output_format
|
TS_UNIX
|
Must be one of the constants listed in the formats table. |
$timestamp
|
本级路径 | Should be a literal timestamp (e.g. 2010-12-03 22:07:25). Any format listed in the formats table can be used.
|
- Call with no arguments to return the current time in UNIX time format.
echo wfTimestamp(); // 1713094343
- Call with one argument to return the current time in the specified format.
echo wfTimestamp( TS_ISO_8601 ); // 2024-04-14T11:32:23Z
- Call with two arguments to return an arbitrary timestamp in the specified format.
Note that the timestamp can be in any format that wfTimestamp() can output.
$timestamp = 20240423113223;
echo wfTimestamp( TS_ISO_8601, $timestamp ); // 2024-04-14T11:32:23Z
$timestamp = '2024-04-14T11:32:23Z';
echo wfTimestamp( TS_RFC2822, $timestamp ); // Sun, 14 Apr 2024 11:32:23 GMT
