php-pdo 用 ODBC 连接 MSSQLSERVER Y也是怪麻烦的：SQLSTATE[08001] SQLDriverConnect: 10054 [Microsoft][ODBC Driver 17 for SQL Server]TCP Provider: Error code 0x2746

语法似乎都对了， 可还是连不上。

<?php

$DB_HOST = "10.150.1.88,1433";
//$DB_HOST = "localhost,1433";
$DB_NAME = "db_wchar";
$DB_CHARSET = "utf8";
$DB_USER = "sa";
$DB_PASSWORD = "wtfwtfwtf";

// CONNECTING

try {
     //$dsn = new PDO( "sqlsrv:Server=$DB_HOST; Database=$DB_NAME; ", $DB_USER,  $DB_PASSWORD );  
     $dsn = new PDO("odbc:driver={/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.10.so.1.1};

    }
catch (PDOException $e) {
    echo " yuck! Failed to get DB handle: " . $e->getMessage() . "\n";
    exit;
  }

$sql_string = $dsn->prepare("select top 10 id from table");
$sql_string->execute();
while ($row = $sql_string->fetch()) {
    print_r($row);
  }
  unset($dsn); unset($sql_string);
  
?>

ODBC 驱动的绝对路径都写了


$dsn = new PDO("odbc:driver={/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.10.so.1.1};

据说，关键字的 等号前后不能有空格。这也会影响。

Array ( [0] => dblib [1] => mysql [2] => odbc [3] => sqlite [4] => sqlsrv )
Caught PDO exception:

https://stackoverflow.com/questions/46062779/neither-dsn-nor-server-keyword-supplied

好吧。把空格干掉。
还是不行：

Caught PDO exception:

SQLSTATE[08001] SQLDriverConnect: -1 [Microsoft][ODBC Driver 17 for SQL Server]

换个驱动？ 11 版？
$conn=new PDO("odbc:DRIVER={ODBC Driver 11 for SQL Server}; server=$serverName; Database=$databaseName; Encrypt=No;", $uid, $pwd);Caught PDO exception:

<hr/>碰到这个问题的人似乎不少。

https://github.com/microsoft/msphpsql/issues/252
TCP Provider: Error code 0x2746. Client unable to establish connection. #252

用相同的凭证从相同的网络服务器连接到相同的数据库，并使用nodejs mssql模块确实可以工作，
所以这不是一个防火墙问题。
是的， 俺用 PYTHON 的 PYMSSQL  从相同的电脑连接到相同的数据库确实可以工作，
排除了防火墙的问题。

附录： 防火墙命令
To display all services, type:
$ sudo firewall-cmd --get-services

Allow inbound traffic
To allow inbound traffic for mssql service, type:
$ sudo firewall-cmd --zone=public --add-service=mssql

To verify the services added:
$ sudo firewall-cmd --zone=public --list-services

To persist the change even after a reboot, invoke the --permanent option as follows.
$ sudo firewall-cmd --zone=public --add-service=https --permanent

To make the changes come into effect, reload the firewalld
$ sudo firewall-cmd --reload


To remove a service from the firewall, use the --remove option
$ sudo firewall-cmd --zone=public --remove-service=https --permanent

<hr/>好吧， 退一步。
用微软的示范代码。

https://docs.microsoft.com/en-us/sql/connect/php/installation-tutorial-linux-mac?view=sql-server-ver16

<?php
try {
    $serverName = "yourServername";
    $databaseName = "yourDatabase";
    $uid = "yourUsername";
    $pwd = "yourPassword";
   
    $conn = new PDO("sqlsrv:server = $serverName; Database = $databaseName;", $uid, $pwd);

    // Select Query
    $tsql = "SELECT @@Version AS SQL_VERSION";

    // Executes the query
    $stmt = $conn->query($tsql);
} catch (PDOException $exception1) {
    echo "<h1>Caught PDO exception:</h1>";
    echo $exception1->getMessage() . PHP_EOL;
    echo "<h1>PHP Info for troubleshooting</h1>";
    phpinfo();
}

?>

<h1> Success Results : </h1>

<?php
try {
    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
        echo $row['SQL_VERSION'] . PHP_EOL;
    }
} catch (PDOException $exception2) {
    // Display errors
    echo "<h1>Caught PDO exception:</h1>";
    echo $exception2->getMessage() . PHP_EOL;
}

unset($stmt);
unset($conn);
?>
还是不行啊。
Caught PDO exception:
SQLSTATE[08001]: [Microsoft][ODBC Driver 17 for SQL Server]TCP Provider: Error code 0x2746



如果端口号出错， 提示也是不同的：
SQLSTATE[HYT00] SQLDriverConnect: 0 [Microsoft]
[ODBC Driver 18 for SQL Server]Login timeout expired


    $serverName = "xpvbxvmdad,14333";

    $conn=new PDO("odbc:DRIVER={/opt/microsoft/msodbcsql18/lib64/libmsodbcsql-18.1.so.1.1};Server=$serverName;Database=$databaseName",$uid,$pwd);
    //$conn=new PDO("odbc:DRIVER={/opt/microsoft/msodbcsql18/lib64/libmsodbcsql-18.1.so.1.1};server=$serverName;Database=$databaseName;Encrypt=Yes",$uid,$pwd);
if the port number is set wrong on purpose, the result will be different

    $serverName = "10.150.1.172,14333";


as following:

Caught PDO exception:
SQLSTATE[HYT00]: [Microsoft][ODBC Driver 17 for SQL Server]Login timeout expired

装了 LINUX 版本的 SQL SERVER 也是不行。

pdo 不给力。
要不要试试  ODBC unified ， ODBC (Unified) ？

这个例子是 WINDOWS 的， 不适用。

<?php
// Microsoft SQL Server using the SQL Native Client 10.0 ODBC Driver - allows connection to SQL 7, 2000, 2005 and 2008
$connection = odbc_connect("Driver={SQL Server Native Client 10.0};Server=$server;Database=$database;", $user, $password);

// Microsoft Access
$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=$mdbFilename", $user, $password);

// Microsoft Excel
$excelFile = realpath('C:/ExcelData.xls');
$excelDir = dirname($excelFile);
$connection = odbc_connect("Driver={Microsoft Excel Driver (*.xls)};DriverId=790;Dbq=$excelFile;DefaultDir=$excelDir" , '', '');
?>

ldconfig 命令
使用ldconfig命令来创建、更新和删除必要的链接和缓存（供运行时链接器ld.so使用），
以便在命令行上指定的目录、文件/etc/ld.so.conf和可信目录（/usr/lib、/lib64和/lib）中找到最新的共享库。
ldconfig命令在确定哪些版本的链接应该被更新时，会检查它所遇到的库的头和文件名。
这个命令还创建了一个叫做/etc/ld.so.cache的文件，用来加快链接速度。
