How long ago will the time be represented? PHP and js dual version _ PHP Tutorial

The time is expressed in the form of the double version of PHP and js. Not much nonsense. The PHPFORSmarty copy code is as follows: * Name: time_ago * Purpose: Use the timestamp to express the timestamp in the form of * Second within 1 minute * nonsense within 1 hour.
Php for Smarty

The code is as follows:

* Name: time_ago
* Purpose: specify the timestamp as a representation of the current time.
* Per second in 1 minute
* Display by minute within one hour
* Display on time within 1 day
* Displayed as yesterday in three days, the day before yesterday
* Display the specific date in more than 3 days
*
* @ Author Peter Pan
* @ Param int $ time input int

Javascript
JavaScript is a little more complex, divided into three function implementations

The code is as follows:

/**
* String filling
* @ Param string str string to be filled
* @ Param int len the length of the target string
* @ Param str chr the character used for filling is a space by default.
* @ Param str left | right | both: right by default
*/

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 the date
* Similar to the php Date function, a Unix timestamp (in seconds) is input to return the specified format.
* Format (case insensitive ):
* Y indicates a four-digit year.
* M indicates a two-digit month.
* D indicates a two-digit day.
* H indicates 2 bits
* I indicates two points
* S indicates 2 seconds
