This article will explain in detail how to use PHP and js to express the time in the form of how long ago. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

PHP FOR Smarty

The copy code is as follows:

* Name: time_ago

* Purpose: tailor the timestamp to the representation from the current time

* by second within 1 minute

* display by minute within 1 hour

* display on time within 1 day

* within 3 days to show yesterday and the day before yesterday

* display a specific date in more than 3 days

*

* @ author Peter Pan

* @ param int $time input int

, /

Function smarty_modifier_time_ago ($time) {

$time_deff = time ()-$time

$retrun =''

If ($time_deff > = 259200) {

$retrun = date ('Y-m-d Hridged, $time)

} else if ($time_deff > = 172800) {

$retrun = "day before yesterday". Date ('Hazzieu, $time)

} else if ($time_deff > = 86400) {

$retrun = yesterday. Date ('Hazzieu, $time)

} else if ($time_deff > = 3600) {

$hour = intval ($time_deff / 3600)

$minute = intval (($time_deff% 3600) / 60)

$retrun = $hour. 'hour'

If ($minute > 0) {

Retrun. = $minute. 'minutes'

}

$retrun. = 'front'

} else if ($time_deff > = 60) {

$minute = intval ($time_deff / 60)

$second = $time_deff 60

$retrun = $minute. 'Fen'

If ($second > 0) {

Retrun. = $second. 'seconds'

}

$retrun. = 'front'

} else {

$retrun = $time_deff.' Seconds ago.

}

Return $retrun

}

Javascript

JS is a bit more complex, which is divided into three function implementations.

The copy code is as follows:

/ * *

* string padding

* @ param string str string to be populated

* @ param int len target string length

* @ param str chr the characters used to fill are spaces by default

* @ param str dir fill position left | right | both defaults to right

, /

Function strPad (str, len, chr, dir) {

Str = str.toString ()

Len = (typeof len = = 'number')? Len: 0

Chr = (typeof chr = = 'string')? Chr:''

Dir = (/ left | right | both/i) .test (dir)? Dir: 'right'

Var repeat = function (c, l) {

Var repeat =''

While (repeat.length

< l) { repeat += c; } return repeat.substr(0, l); } var diff = len - str.length; if (diff >

0) {

Switch (dir) {

Case 'left':

Str =''+ repeat (chr, diff) + str

Break

Case 'both':

Var half = repeat (chr, Math.ceil (diff / 2))

Str = (half + str + half) .substr (1, len)

Break

Default:

Str =''+ str + repeat (chr, diff)

}

}

Return str

}

/ * *

* format date

* similar to php Date function, input Unix timestamp (seconds) to return the specified format

* format (case-insensitive):

* y represents a 4-digit year

* m represents a 2-digit month

* d represents a 2-digit day

* h means 2 digits

* I means 2 digits

* s means 2-bit seconds

, /

Function formatDate (format,timestamp) {

Var date = new Date (parseInt (timestamp) * 1000)

Var year = date.getFullYear ()

Var month = date.getMonth ()

Var day = date.getDate ()

Var hour = date.getHours ()

Var minute = date.getMinutes ()

Var second = date.getSeconds ()

Month = strPad (month,2,'0','left')

Day = strPad (day,2,'0','left')

Hour = strPad (hour,2,'0','left')

Minute = strPad (minute,2,'0','left')

Second = strPad (second,2,'0','left')

Format = format.replace (/ ybinGil year)

Format = format.replace (/ mbingijimonmonth)

Format = format.replace (/ dbingidyday)

Format = format.replace (/ hmp gijjol hour)

Format = format.replace (/ iBandgijime)

Format = format.replace (/ scompgimme second)

Return format

}

Function timeAgo (time) {

Var nowTime = Date.parse (new Date ()) / 1000

Var time_deff = nowTime-time

Retrun =''

If (time_deff > = 259200) {

Retrun = formatDate ('Y-m-d hijack, time)

} else if (time_deff > = 172800) {

Retrun = "the day before yesterday" + formatDate ('Hizujah, time)

} else if (time_deff > = 86400) {

Retrun = "yesterday" + formatDate ('Havana, time)

} else if (time_deff > = 3600) {

Hour = parseInt (time_deff / 3600)

Minute = parseInt ((time_deff% 3600) / 60)

Retrun = hour + 'hour'

If (minute > 0) {

Retrun + = minute + 'minutes'

}

Retrun + = 'front'

} else if (time_deff > = 60) {

Minute = parseInt ($time_deff / 60)

Second = time_deff 60

Retrun = minute + 'min'

If (second > 0) {

Retrun + = second + 'seconds'

}

Retrun + = 'front'

} else {

Retrun = time_deff + 'seconds ago'

}

Return retrun

}
