Quick mastery of PHP json cryptographic functions using _php Tutorial

The following are the specific applications of PHP JSON cryptographic functions:

2. function Php_json_encode ($arr)
4. {
6. $ Json_str = "" ;
8. if (Is_array ($arr))
10. {
12. $ Pure_array = true ;
14. $ Array_length = Count ($arr);
16. For ($i=0; $i<$array _length; $i + +)
18. {
20. if (! isset ($arr [$i]))
22. {
24. $ Pure_array = false ;
26. Break
28. }
30. }
32. if ($pure _array)
34. {
36. $ Json_str = "[";
38. $ Temp = Array ();
40. For ($i=0; $i<$array _length; $i + +)
42. {
44. $temp [] = sprintf ("%s", Php_json_encode ($arr [$i]);
46. }
48. $json _str . = implode (",", $temp);
50. $json _str . = "]";
52. }
54. Else
56. {
58. $ Json_str = "{";
60. $ Temp = Array ();
62. foreach ($arr as $key => $value)
64. {
66. $temp [] = sprintf ("" "%s":%s ", $key, Php_json_encode ($value));
68. }
70. $json _str . = implode (",", $temp);
72. $json _str . = "}";
74. }
76. }
78. Else
80. {
82. if (is_string ($arr))
84. {
86. $ Json_str = "" ". Json_encode_string ($arr). """;
88. }
90. else if (Is_numeric ($arr))
92. {
94. $ Json_str = $arr;
96. }
98. Else
100. {
102. $ Json_str = "" ". Json_encode_string ($arr). """;
104. }
106. }
108. return $json _str;
110. }

Hope that through the above code demonstration, you can fully grasp the PHP JSON cryptographic function usage, to help you improve code programming.
