php连接postgresql

在ubuntu下用php连接postgresql需要下个模块php5-pgsql

连接数据库并显示一张表的内容：

<?php
#连接数据库
$conn = pg_connect("host=localhost port=5432 dbname=test1 user=jm password=123");
if (!$conn)
    echo "连接失败！！！！！<br>";
else
    echo "连接成功=====@@@@======<br>";

#执行查询语句
 $sql="select * from book";
 $ret = pg_query($conn, $sql);

 #显示数据表
 while($row = pg_fetch_row($ret)){
      echo "ID = ". $row[0] . "\n";
      echo "NAME = ". $row[1] ."\n";
      echo "ADDRESS = ". $row[2] ."\n";
      echo "SALARY =  ".$row[4] ."\n\n";
      echo "<br>";
   }

 pg_close($conn);
?>
