php教程 如何连接MS SQL Server 数据库教程

下面是连接到MSSQL服务器数据库代码。

?php$myServer = localhost;$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 h1 . $numRows . Row . ($numRows == 1 ? : s) . Returned

/h1;

//display the results while($row = mssql_fetch_array($result)){ echo li . $row[id] . $row[name] . $row[year] . /li;}//close the connectionmssql_close($dbhandle);?

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'。

?php

//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 table border=1tr;

//print field name $colName = odbc_num_fields($result); for ($j=1; $j= $colName; $j++) { echo th; echo odbc_field_name ($result, $j ); echo /th; }

//fetch tha data from the database while(odbc_lom599乐百家手机 ,fetch_row($result)) { echo tr; for($i=1;$i=odbc_num_fields($result);$i++) { echo td; echo odbc_result($result,$i); echo /td; } echo /tr; }

echo /td /tr; echo /table ;

//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,其中包括文字,字

体,图像和二维矢量图形,撰写文件。

function pdf2text($filename) {

百家了乐八大技巧 ,// 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); }
