Summary of methods for connecting php to MSsql server
May 18, 2018 pm 02:14 PM
This time I will bring you a summary of the methods of php connecting to MSsql server. What are the precautions of the method of php connecting to MSsql server. The following is a practical case, let's take a look.
1. Through mssql_ series functions
mssql_ series functions are mainly used for versions below php5.3 and sqlserver2000 and above.
In php.ini, remove the semicolon in front of;extension=php_mssql.dll;extension=php_msql.dll;extension=php_pdo_mssql.dll;extension=php_pdo_odbc.dll.
<?php
$server ="localhost"; //服務(wù)器IP地址,如果是本地，可以寫成localhost
$uid ="sa"; //用戶名
$pwd ="123456"; //密碼
$database ="jb51net"; //數(shù)據(jù)庫名稱
////進(jìn)行數(shù)據(jù)庫連接
$conn =mssql_connect($server,$uid,$pwd) or die ("connect failed");
mssql_select_db($database,$conn);
////執(zhí)行查詢語句
$query ="select * from A_PHP";
$row =mssql_query($query);
////打印輸出查詢結(jié)果
while($list=mssql_fetch_array($row))
{
print_r($list);
echo "<br>";
?}
?>
2. Through the sqlsrv_ series of functions
sqlsrv_ series of functions are mainly aimed at php5.3 or above and sql server 2005 or above use.
You need to download and install the Microsoft Drivers for PHP for SQL Server driver, address: https://msdn.microsoft.com/library/dn865013.aspx. After downloading, unzip it and put it in the ext directory corresponding to php. Then open the php.ini file and add the configuration after extension
extension=php_pdo_sqlsrv_53_ts.dll
extension=php_sqlsrv_53_ts.dll
Restart apache and check phpinfo( ), make sure apache already supports sqlsrv. As shown in the figure below:
And install sqlncli.msi. This file is to assist windows environmentto access the database server where the sql server is located
<?php
$serverName = "localhost";
$connectionInfo = array( "Database"=>"jb51net",?"UID"=>"sa",?"PWD"=>"123456");
?$conn?=?sqlsrv_connect(?$serverName,?$connectionInfo?);
?if(?$conn?===?false?)?{
???die(?print_r(?sqlsrv_errors(),?true));
?}
?$sql?=?"SELECT?*?FROM?dbo.A_PHP";
?$stmt?=?sqlsrv_query(?$conn,?$sql?);
?if(?$stmt?===?false)?{
???die(?print_r(?sqlsrv_errors(),?true)?);
?}
?while($row?=?sqlsrv_fetch_array($stmt))
?{echo?$row[0]."-----".$row[1]."<br/>";}
?> 3. Connect the sqlserver series through odbc method.
You need to enable the php_pdo_odbc.dll extension in php.ini.
<?php
$con?=?odbc_connect('DRIVER={SQL?Server};SERVER=localhost;DATABASE=jb51net,'sa','123456');
$query?=?"SELECT?*?FROM?dbo.A_PHP";
$result?=?odbc_do($con,$query);
while(odbc_fetch_row($result))
{
??$list?=?odbc_result($result,?"id"); print_r($list);echo?'<br/>';
}
?>
4. Connect to sqlserver through PDO.
Enable the php_pdo_mssql.dll extension in php.ini. You can view
<?php
$conn = new PDO("sqlsrv:server=localhost;database=jb51net","sa","123456");
$sql = "select count(*) count from CKXS2";
$res = $conn->query($sql);
?while?($row?=?$res->fetch()){
?print_r($row);
?}
?>
in phpinfo. 5. Connect through COM.
The following is the implementation code:
<?php
$conn = new Com("ADODB.Connection"); //實(shí)例化一個(gè)Connection對(duì)象
$connstr = "provider=sqloledb;datasource=.;uid=sa;pwd=123456;database=jb51net;";
$conn->Open($connstr);?
?$rs?=?new?Com("ADODB.Recordset");?//實(shí)例化一個(gè)Recordcount對(duì)象?
?$rs->Open('select?*?from?CKXS2?',?$conn,?1,?1);?
?$count?=?$rs->RecordCount;?
?echo?"共有{$count}條紀(jì)錄<br />";?
?>

PHP calls AI intelligent voice assistant PHP voice interaction system construction
Jul 25, 2025 pm 08:45 PM
User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.
How to use PHP to build social sharing functions PHP sharing interface integration practice
Jul 25, 2025 pm 08:51 PM
The core method of building social sharing functions in PHP is to dynamically generate sharing links that meet the requirements of each platform. 1. First get the current page or specified URL and article information; 2. Use urlencode to encode the parameters; 3. Splice and generate sharing links according to the protocols of each platform; 4. Display links on the front end for users to click and share; 5. Dynamically generate OG tags on the page to optimize sharing content display; 6. Be sure to escape user input to prevent XSS attacks. This method does not require complex authentication, has low maintenance costs, and is suitable for most content sharing needs.

Jul 25, 2025 pm 08:57 PM
To realize text error correction and syntax optimization with AI, you need to follow the following steps: 1. Select a suitable AI model or API, such as Baidu, Tencent API or open source NLP library; 2. Call the API through PHP's curl or Guzzle and process the return results; 3. Display error correction information in the application and allow users to choose whether to adopt it; 4. Use php-l and PHP_CodeSniffer for syntax detection and code optimization; 5. Continuously collect feedback and update the model or rules to improve the effect. When choosing AIAPI, focus on evaluating accuracy, response speed, price and support for PHP. Code optimization should follow PSR specifications, use cache reasonably, avoid circular queries, review code regularly, and use X
PHP creates a blog comment system to monetize PHP comment review and anti-brush strategy
Jul 25, 2025 pm 08:27 PM
1. Maximizing the commercial value of the comment system requires combining native advertising precise delivery, user paid value-added services (such as uploading pictures, top-up comments), influence incentive mechanism based on comment quality, and compliance anonymous data insight monetization; 2. The audit strategy should adopt a combination of pre-audit dynamic keyword filtering and user reporting mechanisms, supplemented by comment quality rating to achieve content hierarchical exposure; 3. Anti-brushing requires the construction of multi-layer defense: reCAPTCHAv3 sensorless verification, Honeypot honeypot field recognition robot, IP and timestamp frequency limit prevents watering, and content pattern recognition marks suspicious comments, and continuously iterate to deal with attacks.
How to use PHP to combine AI to generate image. PHP automatically generates art works
Jul 25, 2025 pm 07:21 PM
PHP does not directly perform AI image processing, but integrates through APIs, because it is good at web development rather than computing-intensive tasks. API integration can achieve professional division of labor, reduce costs, and improve efficiency; 2. Integrating key technologies include using Guzzle or cURL to send HTTP requests, JSON data encoding and decoding, API key security authentication, asynchronous queue processing time-consuming tasks, robust error handling and retry mechanism, image storage and display; 3. Common challenges include API cost out of control, uncontrollable generation results, poor user experience, security risks and difficult data management. The response strategies are setting user quotas and caches, providing propt guidance and multi-picture selection, asynchronous notifications and progress prompts, key environment variable storage and content audit, and cloud storage.
PHP realizes commodity inventory management and monetization PHP inventory synchronization and alarm mechanism
Jul 25, 2025 pm 08:30 PM
PHP ensures inventory deduction atomicity through database transactions and FORUPDATE row locks to prevent high concurrent overselling; 2. Multi-platform inventory consistency depends on centralized management and event-driven synchronization, combining API/Webhook notifications and message queues to ensure reliable data transmission; 3. The alarm mechanism should set low inventory, zero/negative inventory, unsalable sales, replenishment cycles and abnormal fluctuations strategies in different scenarios, and select DingTalk, SMS or Email Responsible Persons according to the urgency, and the alarm information must be complete and clear to achieve business adaptation and rapid response.
