新版本是2.05添加了很多支持,包括 CodeIgniter,MSSQL, PDO 等等
我之前也为 CodeIgniter 写过一次,不过只支持 MySQL

看看使用示例
其实也没什么难度,直接看源代码即可,主要是程序设计的思想很好。

Example 1
----------------------------------------------------

// Select multiple records from the database and print them out..
$users = $db->get_results("SELECT name, email FROM users");
foreach ( $users as $user ) {
// Access data using object syntax
echo $user->name;
echo $user->email;
}
Example 2
----------------------------------------------------

// Get one row from the database and print it out..
$user = $db->get_row("SELECT name,email FROM users WHERE id = 2");
echo $user->name;
echo $user->email;
Example 3
----------------------------------------------------

// Get one variable from the database and print it out..
$var = $db->get_var("SELECT count(*) FROM users");
echo $var;
Example 4
----------------------------------------------------

// Insert into the database
$db->query("INSERT INTO users (id, name, email) VALUES (NULL,'justin','jv@foo.com')");
Example 5
----------------------------------------------------

// Update the database
$db->query("UPDATE users SET name = 'Justin' WHERE id = 2)");
Example 6
----------------------------------------------------

// Display last query and all associated results
$db->debug();
Example 7
----------------------------------------------------

// Display the structure and contents of any result(s) .. or any variable
$results = $db->get_results("SELECT name, email FROM users");
$db->vardump($results);
Example 8
----------------------------------------------------

// Get 'one column' (based on column index) and print it out..
$names = $db->get_col("SELECT name,email FROM users",0)
foreach ( $names as $name ) {
echo $name;
}
Example 9
----------------------------------------------------

// Same as above ‘but quicker'
foreach ( $db->get_col("SELECT name,email FROM users",0) as $name ) {
echo $name;
}
Example 10
----------------------------------------------------

// Map out the full schema of any given database and print it out..
$db->select("my_database");
foreach ( $db->get_col("SHOW TABLES",0) as $table_name ) {
$db->debug();
$db->get_results("DESC $table_name");
}
$db->debug();

EZSQL类介绍:

ezsql是一个小型的快速的数据库操作类,可以让你很容易地用PHP操作各种数据库( MySQL、oracle8/9 、interbase、FireBird、PostgreSQL、MS-SQL、sqlite、sqlite C++)。
在你的脚本开头是要包含一个一个PHP文件。然后,你就可以使用更小、更容易的一套ezsql函数来代替标准的PHP数据库函数。
