The correct interpretation of PHP application ODBC tips _php Tutorial

When we are applying

PHP application ODBC specific code:

2. Class odbc_db
4. {
6. var $ Con = NULL ;
8. var $ Resource = NULL ;
10. function __construct ()
12. {
14. }
16. function Connect ($dsn = ",
    $user = ", $passwd =",
    $cursor_type = 0)
18. {
20. ! $dsn && $this- > Debug (' DSN not provided! ');
22. $this- > Con = Odbc_connect ($DSN, $user
    , $passwd, $cursor _type);
24. ! $this- > con && $this- > Debug (' Conncet failed! ');
26. return $this- > con;
28. }
30. function Query ($sql = ")
32. {
34. $this- > Resource = odbc_exec ($this->con, $sql);
36. ! $this- > resource && $this- > Debug
    (' Query failed! ');
38. return $this- > resource;
40. }
42. function Fetch_array ($resource = ")
44. {
46. ! $resource && $ Resource = $this- > resource;
48. Return Odbc_fetch_array ($resource);
50. }
52. function Query_first ($sql = ")
54. {
56. $ Resource = $this- > query ($sql);
58. Return Odbc_fetch_array ($resource);
60. }
62. function Fetch_all ($resource = ")
64. {
66. ! $resource && $ Resource = $this- > resource;
68. $ Results = Array ();
70. While (False!== ($row = @odbc_fetch_
    Array ($resource)))
72. {
74. $results [] = $row;
76. }
78. return $results;
80. }
82. function Num_rows ()
84. {
86. return Odbc_num_rows ($this->con);
88. }
90. function Affected_rows ()
92. {
94. return Odbc_num_rows ($this->con);
96. }
98. function Debug ($message = ")
100. {
102. $message . = '
104. The following error message is provided by ODBC: '. Odbc_errormsg ();
106. Exit ($message);
108. }
110. function __destruct ()
112. {
114. odbc_close ($this->con);
116. }
118. }
120. ?>

The above is the PHP application of all the methods of ODBC, we hope to help.
