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_format argument.
  • Throws MWException if an incorrect formats is passed via the $output_format argument.
  • Returns false if an invalid or unrecognized timestamp is passed via the $timestamp argument.
参数 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(); // 1753761115

Call with one argument to return the current time in the specified format.

echo wfTimestamp( TS_ISO_8601 ); // 2025-07-29T03:51:55Z

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 = 20250755035155; echo wfTimestamp( TS_ISO_8601, $timestamp ); // 2025-07-29T03:51:55Z $timestamp = '2025-07-29T03:51:55Z'; echo wfTimestamp( TS_RFC2822, $timestamp ); // Tue, 29 Jul 2025 03:51:55 GMT
