configure時に、--with-pdo-mysql --with-pdo-pgsqlをつける。

make clean
./configure --enable-mbstring --with-openssl --with-iconv=/usr/local --with-apxs2=/usr/bin/apxs2 --enable-zts --with-pdo-mysql --with-pdo-pgsql
make clean
make
sudo make install

phpinfoの確認。以下phpinfo.phpを作成する。

<?php phpinfo();
?>

PDO関係はどうなっているか確認する。

php phpinfo.php | grep PDO
PDO
PDO support => enabled
PDO drivers => pgsql, sqlite, mysql
PDO Driver for MySQL => enabled
PDO Driver for PostgreSQL => enabled
PDO Driver for SQLite 3.x => enabled
Firebird driver for PDO => Ard Biesheuvel
MySQL driver for PDO => George Schlossnagle, Wez Furlong, Ilia Alshanetsky, Johannes Schlueter
ODBC driver for PDO => Wez Furlong
Oracle (OCI) driver for PDO => Wez Furlong
PostgreSQL driver for PDO => Edin Kadribasic, Ilia Alshanetsky
SQLite 3.x driver for PDO => Wez Furlong

PostgreSQL、MySQLともにドライバがインストールされたようだ。接続コードはdbquery先頭にmysql:かpgsql:をつければOK

<?php $dbuser = 'hogedbuser';
$dbpass = 'hogedbpass';
$dbhost = '127.0.0.1';
$dbname = 'hogedbname';
$dbquery = "mysql:host=$dbhost;dbname=$dbname;";
// $dbquery = "pgsql:host=$dbhost;dbname=$dbname;";
try {
  $dbconn = new PDO($dbquery, $dbuser, $dbpass);
  //ok
  echo "connection success\n";
  $sql = 'select count(*) from zipdata';
  foreach ($dbconn->query($sql) as $row) {
       print($row['count']);
  }
  //close
  $dbconn = null;
}
catch (PDOException $e) {
  echo 'connection error: ' . $e->getMessage() . "\n";
}

実行

connection success 115555
# 失敗時
connection error: SQLSTATE[HY000] [1698] Access denied for user 'hogedbuser'@'localhost'
