php如何连接和操作PostgreSQL数据库

这篇文章主要介绍了php连接与操作PostgreSQL数据库的方法,以实例形式较为详细的分析了php连接PostgreSQL数据库以及进行读取与增加、修改、删除等技巧,具有一定的参考借鉴价值,需要的朋友可以参考下

具体实现方法如下：

代码如下:

$pg=@pg_connect("host=localhost user=postgres password=sa dbname=employes") 
or die("can't connect to database."); 
$query="select * from employes order by serial_no"; 
//$query="insert into employes values(10008,'susan','1985-09-04','80','50')"; 
$result=@pg_query($pg,$query) or die("can't run query to table."); 
//echo pg_num_rows($result); //输出多少条记录被查询 
//if($result) 
//{ 
//echo "recrods inserted sucessfully!"; 
//echo pg_affected_rows($result);//输出多少条记录被插入 
//} 
//实例一[pg_fetch_row] 
echo "<table border=1>"; 
echo "<tr>"; 
echo "<td>serial_no</td>"; 
echo"<td>name</td>"; 
echo"<td>birthday</td>"; 
echo"</tr>"; 
for($i=0;$i<pg_num_rows($result);$i++) 
{ 
$row=@pg_fetch_row($result) or die("can&#39;t fetch row from table."); 
$serial_no= $row[0]; 
$name= $row[1]; 
$birthday= $row[2]; 
echo"<tr>"; 
echo"<td>$serial_no</td>"; 
echo"<td>$name</td>"; 
echo"<td>$birthday</td>"; 
echo"</tr>"; 
} 
echo"</table>"; 
//实例二[pg_fetch_array] 
//echo "<table border=1>"; 
//echo "<tr>"; 
//echo "<td>serial_no</td>"; 
//echo"<td>name</td>"; 
//echo"<td>birthday</td>"; 
//echo"</tr>"; 
// 
//for($i=0;$i<pg_num_rows($result);$i++) 
//{ 
// 
//$row=@pg_fetch_array($result) or die("can&#39;t fetch row from table."); 
//$serial_no= $row[&#39;serial_no&#39;]; 
//$name= $row[&#39;name&#39;]; 
//$birthday= $row[&#39;birthday&#39;]; 
//echo"<tr>"; 
//echo"<td>$serial_no</td>"; 
//echo"<td>$name</td>"; 
//echo"<td>$birthday</td>"; 
//echo"</tr>"; 
// 
//} 
//echo"</table>"; 
//增加,删除,修改实例 
//$newrow=array("serial_no"=>"1006","name"=>"peter","birthday"=>"1990-07-03","salary"=>"90","bonus"=>"80"); 
//$reusult=@pg_insert($pg,"employes",$newrow) or die("can&#39;t insert data to table.");
//if($reusult) 
//{ 
//echo "rechords inserted sucessfully!"; 
//} 
// 
pg_close($pg);
