Several ways to get time from PHP

function Getweekname ($data, $format = ' Week ') { $week = Date ("D", $data); Switch ($week) { Case "Mon": $current = $format. " One "; Break Case "Tue": $current = $format. " Two "; Break Case "Wed": $current = $format. " Three "; Break Case "Thu": $current = $format. " Four "; Break Case "Fri": $current = $format. " Five "; Break Case "Sat": $current = $format. " Six "; Break Case "Sun": $current = $format. " Day "; Break } return $current; } Echo ' Today is: '. Getweekname (Time (), ' Week '); Echo ' '; Echo ' Today is: '. Getweekname (Time (), ' worship '); Echo ' '; Echo ' 2010-12-12 is: '. Getweekname (Strtotime (' 2010-12-12 '), ' worship '); ?> Copy Code 4. Get a custom function that looks like a few hours before the article was published function Time2units ($time) { $year = Floor ($time/60/60/24/365); $time-= $year * 60 * 60 * 24 * 365; $month = Floor ($time/60/60/24/30); $time-= $month * 60 * 60 * 24 * 30; $week = Floor ($time/60/60/24/7); $time-= $week * 60 * 60 * 24 * 7; $day = Floor ($time/60/60/24); $time-= $day * 60 * 60 * 24; $hour = Floor ($time/60/60); $time-= $hour * 60 * 60; $minute = Floor ($time/60); $time-= $minute * 60; $second = $time; $elapse = "; $UNITARR = Array (' Year ' = ' + ' Years ', ' month ' = ' ' month ', ' Week ' = ' ' Week ', ' Day ' = ' ~ ', ' Hours ' = ' hour ', ' minutes ' = ' minute ', ' sec ' = ' second ' ); foreach ($unitArr as $CN = $u) { if ($ $u > 0) { $elapse = $ $u. $CN; Break } } return $elapse; } $past = 2052345678; Release date $now = time (); Current date $diff = $now-$past;//Difference value Echo ' published in '. Time2units ($diff). ' former '; ?> Copy Code Another, personally considered better: function Time_tran ($the _time) { $now _time = Date ("Y-m-d h:i:s", Time () +8*60*60); $now _time = strtotime ($now _time); $show _time = strtotime ($the _time); $dur = $now _time-$show _time; if ($dur < 0) { return $the _time; }else{ if ($dur < 60) { return $dur. ' seconds ago '; }else{ if ($dur < 3600) { Return floor ($dur/60). ' Minutes ago '; }else{ if ($dur < 86400) { Return floor ($dur/3600). ' Hours ago '; }else{ if ($dur < 259200) {//within 3 days Return floor ($dur/86400). ' Days ago '; }else{ return $the _time; } } } } } } ?> Copy Code 5, according to the two time difference between the specific calculation difference function GetTime ($val) { if ($val >0) { $nTime [' nday '] = (int) ($val/(3600*24)); $nTime [' nhour '] = (int) ($val% (3600*24)/3600); $nTime [' nMin '] = (int) ($val% (3600*24)%3600/60); $nTime [' nSec '] = (int) ($val% (3600*24)%3600%60); } return $nTime; } function Getstrtime ($val) { $aTime = GetTime ($val); $dtoc = Array (' nday ' = ' + ' days ', ' nhour ' = ' h ', ' nMin ' = ' min ', ' nSec ' = ' s '); if ($aTime) { foreach ($aTime as $k = = $v) { if ($v) { $cTime. = $v. $dtoc [$k]; } } }else{ $cTime = ' closed '; } return $cTime; } ?> Copy Code
