PHP中将时间差转换为字符串提示的实现代码

如微博

这看起来更加人性化，好吧，上代码
代码如下:

1. <?php
   
2. class timeAgo
   
3. {
   
4. static $timeagoObject;
   
5. private $rustle;
   
6. private $unit;
   
7. 
   
8. private function __construct()
   
9. {
   
10. 
    
11. }
    
12. private function __clone(){ }
    
13. public static function getObject()
    
14. {
    
15. if(! (self::$timeagoObject instanceof self) )
    
16. self::$timeagoObject = new timeAgo();
    
17. 
    
18. return self::$timeagoObject;
    
19. }
    
20. private function count_int($unix_C) // main function
    
21. {
    
22. if(! (isset($unix_C) || is_numeric($unix_C)) )
    
23. return 'don\'t find parameter';
    
24. 
    
25. $d = time()-$unix_C ; // $d - unix time difference value
    
26. $d_int =(int)floor($d/60) ; // minimum unit -- minutes unix/60
    
27. 
    
28. $this->unit = 0 ; // is minutes,hour or day?
    
29. 
    
30. if($d_int < 60){ // minutes in one hour 3600
    
31. $this->rustle = $d_int;
    
32. $this->unit = 1;
    
33. }
    
34. else if($d_int < 720){ //hour in one day 3600*12
    
35. $this->rustle = floor($d_int/60);
    
36. $this->unit = 2 ;
    
37. }
    
38. else if($d_int < 7200){ //day in ten days 3600*12*10
    
39. $this->rustle = floor($d_int/720);
    
40. $this->unit = 3 ;
    
41. }
    
42. else{
    
43. $this->rustle = $d ;
    
44. $this->unit = 4 ;
    
45. }
    
46. }
    
47. public function piece_str($C)
    
48. {
    
49. $this->count_int($C);
    
50. 
    
51. $u = '';
    
52. switch( $this->unit )
    
53. {
    
54. case 1:
    
55. $u = 'minute';
    
56. break;
    
57. case 2:
    
58. $u = 'hour';
    
59. break;
    
60. case 3:
    
61. $u = 'day';
    
62. break;
    
63. case 4:
    
64. $u = '';
    
65. break;
    
66. case 0:
    
67. return 'sorry , get time is fail';
    
68. }
    
69. if($this->unit < 4)
    
70. {
    
71. if($this->rustle > 1)
    
72. return (string)$this->rustle.$u.'s ago';
    
73. else if($this->rustle == 1)
    
74. return (string)$this->rustle.$u.'ago';
    
75. else
    
76. return 'Just now';
    
77. }
    
78. }
    
79. /* example: $ago = timeAgo::getObject();
    
80. * echo $ago->piece_str($unix);
    
81. * // 2 days ago
    
82. */
    
83. }
    
84. ?>
