本文介绍了在几天前更改PHP日期的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在Joumla上使用一个组件，该组件以以下格式返回日期：2个月零6天。 但是我需要这样显示日期： xx秒前或xx分钟前或xx小时前或xx天前。

I am using a component on Joumla that returns dates in this format: 2 months and 6 days ago. But I need the date to be displayed like this: xx seconds ago or xx minutes ago or xx hours ago or xx days ago.

开发人员告诉我，我必须修改此代码，但我对Php完全陌生。今天我整天连续尝试了12个多小时，而我成功完成的工作就是破坏我的网站。

The developer told me I have to modify this code, but I am completely new to Php. I tried all day today for over 12 hours in a row, and all I was successfully accomplish was to breakdown my site.

所以有人可以帮我这个忙。如果需要，我愿意授予FTP访问权限。这是代码：

So Could anyone give me help with this. I am willing to grant FTP access if is need. this is the code:

function dateFormatFromTo($from, $to = null) { $par = JComponentHelper::getParams( 'com_djclassifieds' ); $to = (($to === null) ? (time()) : ($to)); $to = ((is_int($to)) ? ($to) : (strtotime($to))); $from = ((is_int($from)) ? ($from) : (strtotime($from))); $output = ''; $limit = $par->get('date_format_ago_limit','2'); $units = array ( "COM_DJCLASSIFIEDS_DATE_YEAR" => 29030400, "COM_DJCLASSIFIEDS_DATE_MONTH" => 2419200, "COM_DJCLASSIFIEDS_DATE_WEEK" => 604800, "COM_DJCLASSIFIEDS_DATE_DAY" => 86400, "COM_DJCLASSIFIEDS_DATE_HOUR" => 3600, "COM_DJCLASSIFIEDS_DATE_MINUTE" => 60, "COM_DJCLASSIFIEDS_DATE_SECOND" => 1 ); $diff = abs($from - $to); $suffix = (($from > $to) ? (JTEXT::_('COM_DJCLASSIFIEDS_DATE_FROM_NOW')) : (JTEXT::_('COM_DJCLASSIFIEDS_DATE_AGO'))); $i=0; foreach($units as $unit => $mult){ if($diff >= $mult){ if($i==$limit-1 && $i>0){ $output .= " ".JTEXT::_('COM_DJCLASSIFIEDS_DATE_AND').' '.intval($diff / $mult)." "; }else{ $output .= ", ".intval($diff / $mult)." "; } //$and = (($mult != 1) ? ("") : (JTEXT::_('COM_DJCLASSIFIEDS_DATE_AND'))); //$output .= ", ".$and.intval($diff / $mult)." "; if(intval($diff / $mult) == 1){ $output .= JTEXT::_($unit); }else{ $output .= JTEXT::_($unit."S"); } $diff -= intval($diff / $mult) * $mult; $i++; if($i==$limit){ break; } } } $output .= " ".$suffix; $output = substr($output, strlen(", ")); return $output; }

因此，如果有人可以帮助我，我将不胜感激。如果需要，我可以授予FTP访问权限。 我有PHP 5.3

So, I would greatly appreciate if someone can help me out. I can give FTP access if needed. I have Php 5.3

谢谢

推荐答案

此是 Date_HumanDiff 类的改编

date_default_timezone_set('GMT'); function getDifference($timestamp, $reference = null) { static $MINUTE = 60; static $HOUR = 3600; //static::$MINUTE * 60 static $DAY = 86400; //static::$HOUR * 24 static $WEEK = 604800; //static::$DAY * 7 static $MONTH = 2628000; //static::$YEAR / 12 static $YEAR = 31536000;//static::$DAY * 365 $formats = array( array(0.7 * $MINUTE, '%d seconds ago', 1), array(1.5 * $MINUTE, 'a minute ago', 1), array( 60 * $MINUTE, '%d minutes ago', $MINUTE), array(1.5 * $HOUR, 'an hour ago', 1), array( $DAY, '%d hours ago', $HOUR), array( 2 * $DAY, 'yesterday', 1), array( 7 * $DAY, '%d days ago', $DAY), array(1.5 * $WEEK, 'a week ago', 1), array( $MONTH, '%d weeks ago', $WEEK), array(1.5 * $MONTH, 'a month ago', 1), array( $YEAR, '%d months ago', $MONTH), array(1.5 * $YEAR, 'a year ago', 1), array(PHP_INT_MAX, '%d years ago', $YEAR) ); $futureformats = array( array(0.7 * $MINUTE, 'in a moment', -1), array(1.5 * $MINUTE, 'in a minute', -1), array( 60 * $MINUTE, 'in %d minutes', -$MINUTE), array(1.5 * $HOUR, 'in an hour', -1), array( $DAY, 'in %d hours', -$HOUR), array( 2 * $DAY, 'tomorrow', -1), array( 7 * $DAY, 'in %d days', -$DAY), array(1.5 * $WEEK, 'in a week', -1), array( $MONTH, 'in %d weeks', -$WEEK), array(1.5 * $MONTH, 'in a month', -1), array( $YEAR, 'in %d months', -$MONTH), array(1.5 * $YEAR, 'in a year', -1), array(PHP_INT_MAX, 'in %d years', -$YEAR) ); if ($reference === null) { $reference = time(); } $timestamp = ($timestamp instanceof DateTime) ? $timestamp->getTimestamp() : (is_numeric($timestamp) ? (int)$timestamp : strtotime($timestamp)); $reference = ($reference instanceof DateTime) ? $reference->getTimestamp() : (is_numeric($reference) ? (int)$reference : strtotime($reference)); $delta = $reference - $timestamp; if ($delta >= 0) { foreach ($formats as $format) { if ($delta < $format[0]) { return sprintf($format[1], round($delta / $format[2])); } }; } else { foreach ($futureformats as $format) { if (-$delta < $format[0]) { return sprintf($format[1], round($delta / $format[2])); } }; } } // will output 52 minutes ago echo getDifference('2014-01-15 15:24:00', '2014-01-15 16:16:12') . PHP_EOL; // without second param will output difference with the current time echo getDifference('2014-01-15 15:24:00') . PHP_EOL;
