由于經常要操作新浪云數據庫，特寫了如下數據庫操作類，留做后續學習使用。
sqlTool.class.php源碼如下
<?php
class sqlTool{
private $conn ; // = NULL;
private $port ="3**7";
private $host = SAE_MYSQL_HOST_M;
private $user = "2*wx2*****0";
private $password = "ylx5lj101w****mh1l5i4****h5zzm***3yz";
private $db = "app_s***e*";
public function dblink(){
$this->conn = mysql_connect($this->host.':'.$this->port,$this->user,$this->password);
if(!$this->conn){
die("連接數據庫失敗".mysql_error());
}
mysql_select_db($this->db,$this->conn);
mysql_query("SET names 'UTF8'");
return $this->conn; //為了取$this->conn加上的，如不取這個值，可以不用
}
//完成select語句
public function excute_dql($sql){
$res = mysql_query($sql) or die(mysql_error());
return $res;
}
//完成update,delete,insert
public function excute_dml($sql){
$b = mysql_query($sql,$this->conn);
if(!$b){
return 0; //失敗
}
else
{
if(mysql_affected_rows($this->conn)>0){
return 1; //表示成功
}
else
{
return 2; //表示沒有影響到行數
}
}
}
}
//引用類來操作數據庫
/*
//dml操作
$sql = "insert into slb (hyh,guige,menfu,kezhong,dlj,dlw,slj,slw,spj,spw) values('D15086003FY','50*50 144*80 府綢','57/58',120,150,140,3,3,8,8)";
$a = new sqlTool();
$conn1 = $a->dblink();
$res = $a->excute_dml($sql);
if(!$res){
return 0;
}
else if(mysql_affected_rows($conn1)>0){
echo "操作成功"; // retrun 1;
}
else {
return 2;
}
*/
/*
//dql操作
$sql = "select * from slb ";
$b = new sqlTool();
$b->dblink();
$res = $b->excute_dql($sql);
var_dump($res);
echo "hell";
while($row = mysql_fetch_row($res)){
foreach($row as $key=>$val){
echo "$key-->$val";
}
echo "<br/>";
}
mysql_free_result($res);
*/
?>
sqlTool_demo.PHP 源碼
<?php
require_once "sqlTool.class.php";
//引用類來操作數據庫
//dml操作
/*
// $sql = "insert into slb (hyh,guige,menfu,kezhong,dlj,dlw,slj,slw,spj,spw) values('D15086003FY','50*50 144*80 府綢','57/58',120,150,140,3,3,8,8)";
$sql = "delete from slb where hyh = 'D15086003FY'";
$a = new sqlTool();
$conn1 = $a->dblink();
$res = $a->excute_dml($sql);
if(!$res){
return 0;
}
else if(mysql_affected_rows($conn1)>0){
echo "操作成功"; // retrun 1;
}
else {
return 2;
}
*/
echo "<br>";
//dql操作
$sql = "select * from slb ";
$b = new sqlTool();
$b->dblink(); //因為前面dml操作$conn1 = $a->dblink();此處可以不要，也可以要
$res = $b->excute_dql($sql);
var_dump($res);
echo "hell";
while($row = mysql_fetch_row($res)){
foreach($row as $key=>$val){
echo "$key-->$val";
}
echo "<br/>";
}
mysql_free_result($res);
?>
