下面是连接到MSSQL服务器数据库代码。

$myServer = "localhost";
$myUser = "your_name";
$myPass = "your_password";
$myDB = "examples";

//connection to the database
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
or die("Couldn't connect to SQL Server on $myServer");

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
or die("Couldn't open database $myDB");

//declare the SQL statement that will query the database
$query = "SELECT id, name, year ";
$query .= "FROM cars ";
$query .= "WHERE name='BMW'";

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result);
echo "

" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned

//display the results

DSN的主张'数据源名称'。这是一个简单的方法来分配，容易rememberable有用的数据

源的名称可能不局限于单独的数据库。如果您不知道如何建立一个系统DSN阅读我们的

教程如何建立一个系统DSN。

在下面的例子，我们将告诉你如何以一MSSQL服务器数据库DSN所谓'连接

examples.mdb'和检索所有的记录表中的'车'。

//connect to a DSN "myDSN"
$conn = odbc_connect('myDSN','','');

if ($conn)
{
//the SQL statement that will query the database
$query = "select * from cars";
//perform the query
$result=odbc_exec($conn, $query);

echo "

//print field name
$colName = odbc_num_fields($result);
for ($j=1; $j<= $colName; $j++)
{
echo "

//fetch tha data from the database
while(odbc_fetch_row($result))
{
echo "

echo " ";
echo "

//close the connection
odbc_close ($conn);
}
else echo "odbc not connected";

php 如何把pdf文件转换成txt文本文件

文档格式（PDF）是一种文件格式创建的文件交换。每个PDF文件封装了一个固定布局

的2D文件的完整说明（和，与Acrobat 3D软件，嵌入式3D文件），其中包括文字，字

体，图像和二维矢量图形，撰写文件。

function pdf2text($filename) {

// Read the data from pdf file
$infile = @file_get_contents($filename, FILE_BINARY);
if (empty($infile))
return "";

// Get all text data.
$transformations = array();
$texts = array();

// Get the list of all objects.
preg_match_all("#obj(.*)endobj#ismU", $infile, $objects);
$objects = @$objects[1];

// Select objects with streams.
for ($i = 0; $i < count($objects); $i++) {
$currentObject = $objects[$i];

// Check if an object includes data stream.
if (preg_match("#stream(.*)endstream#ismU", $currentObject,

$stream)) {
$stream = ltrim($stream[1]);

// Check object parameters and look for text data.
$options = getObjectOptions($currentObject);
if (!(empty($options["Length1"]) && empty($options["Type"]) &&

empty($options["Subtype"])))
continue;

// So, we have text data. Decode it.
$data = getDecodedStream($stream, $options);
if (strlen($data)) {
if (preg_match_all("#BT(.*)ET#ismU", $data,

$textContainers)) {
$textContainers = @$textContainers[1];
getDirtyTexts($texts, $textContainers);
} else
getCharTransformations($transformations, $data);
}
}

}

// Analyze text blocks taking into account character transformations

and return results.
return getTextUsingTransformations($texts, $transformations);
}
