SQL写操作 设置内容 （数组转字符串）

SQL

set内容

SQL操作数组转字符串

1. SQL写操作 set内容 （数组转字符串） [ 封装方法 ]

1. function getSqlSet( $data ){ 

   ---

2. $Str = ""; 

   ---

3. foreach( $data as $k => $v ){ 

   ---

4.  

   ---

5. $Str.= $k."=‘".$v."‘,"; 

   ---

6.  

   ---

7. } 

   ---

8. $Str = substr($Str,0,-1); 

   ---

9. return $Str; 

   ---

10. } 

    ---

如执行insert操作(给user添加一条记录)

1. $data = array( 

   ---

2. ‘name‘=>‘张三‘, 

   ---

3. ‘sex‘=>‘男‘, 

   ---

4. ‘idcard‘=>‘341215645646545‘, 

   ---

5. ‘address‘=>‘花果山‘, 

   ---

6. ); 

   ---

7. $str = getSqlSet($data); 

   ---

8. $sql = "INSERT INTO user set {$str}"; // insert ... set 方法为扩展方法，单条记录插入操作较 ...values... 速度快 

   ---

9. mysql_query($sql); 

   ---

2.SQL insert … values… 数组组成字符串方法

1. $data = array( 

   ---

2. ‘name‘=>‘张三‘, 

   ---

3. ‘sex‘=>‘男‘, 

   ---

4. ‘idcard‘=>‘341215645646545‘, 

   ---

5. ‘address‘=>‘花果山‘, 

   ---

6. ); 

   ---

7. $insertkeys = join("‘,‘", array_keys($data) ) ; 

   ---

8. $insertvalues = "‘" . join("‘,‘", array_values($data) ) . "‘"; 

   ---

9. mysql_query( "INSERT INTO user ({$insertkeys}) VALUES ({$insertvalues})" ); 

   ---
