The easiest way to link ACCESS database with PHP
<?PHP //创建ADO连接 $conn = @new COM("ADODB.Connection") or die ("ADO连接失败!"); $connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" . realpath("temp/TempData.mdb"); $conn->Open($connstr); //创建记录集查询 $rs = @new COM("ADODB.RecordSet"); $rs->Open("select * from blog_Content",$conn,1,3); echo $rs->Fields["log_Title"]->Value; //输出log_Title字段 echo "<br/>"; $rs->Movenext(); //将记录集指针下移 echo $rs->Fields["log_Title"]->Value; $rs->close(); ?>
This is just a simple method. We can also connect using Microsoft.Jet.OLEDB.4.0, which will be faster.
Note: conn = @new COM("ADODB.Connection") or die ("ADO connection failed!");
It should be noted that COM must be in uppercase letters. Previously, lowercase letters were used in Windows XP, and illegal operations occurred. Use it here. There is an @ symbol, its main function is fault tolerance!
Other database operation methods are similar to ASP, so I won’t introduce them in detail~
二·
Let’s make a comparison using ASP and PHP together...
ASP program
Program code
1.conn= "DRIVER=Microsoft Access Driver (*.mdb);DBQ=" & Server.MapPath("*.mdb")
2.set conn = server.createobject("adodb.connection" )
3.conn.open conn
4.set rs = Server.CreateObject("adodb.recordset")
5.sql = "select * from table name"
6.rs.Open sql, conn, 3, 1
7.rs.Close
PHP program
Program code
<?PHP 1.$conn = @new COM("ADODB.Connection") or die ("ADO连接失败!"); 2.$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" . realpath("temp/TempData.mdb"); 3.$conn->Open($connstr); 4.$rs = @new COM("ADODB.RecordSet"); 5.$sql ="select * from blog_Content"; 6.$rs->Open($sql,$conn,1,3); 7.$rs->close(); ?>
两个程序都相对应....很好理解了吧.嘿....然后就是ASP和PHP操作记录集了...有什么不同,,看资料了事5~
php: $rs[name/index];
asp: rs(name/index);
php: $rs->Fields["name"]->Value / fields[index]->Value;
asp: rs.fields(index)/rs.field(name);
php中的方法和ASP中基本一致,只是写法上不一样,,注意:PHP区分大小写,写时后面一定要加;号
asp:
修改记录集中的记录
rs.AddNew 向记录集中添加一条新记录
rs.Delete 从记录集中删除一条记录
rs.{fieldName/fieldIndex}=指定值;
rs.Update 保存对当前记录所做的修改
CancelBatch 当记录集处在批量更新模式时)取消一批更新
CancelUpdate 调用Update之前)取消对当前记录所做的所有修改
UpdateBatch 当记录集处于批量更新模式时)保存对一个或多个记录的修改
遍历记录集
Move NumRecords 在记录集中向前或向后移动指定数目的记录数。
MoveFirst 移动到记录集的第一条记录
MoveNext 移动到记录集的下一条记录
MovePrevious 移动到记录集中的上一条记录
MoveLast 移动到记录集的最后一条记录
记录集对象属性
AbsolutePosition 用来设置或读取当前记录在记录集中的位置顺序号
BOF 标明当前位置在记录集中的第一条记录之前
EOF 标明当前位置在记录集中的最后一条记录之后
RecordCount 表示一个记录集中的记录总数
记录集进行分页
AbsolutePage 指定当前的页
PagePount 返回记录集中的逻辑页数
PageSize 指定一个逻辑页中的记录个数,缺省值是10
GetRows() 记录取到数组
MaxRecords 记录集的最大容量

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
