PHP上传Excel并批量添加数据到pgsql的问题,期待高人解答!

Jun 23, 2016 pm 02:10 PM

下面这个代码的作用是上传Excel并读取其中的数据,批量添加数据到pgsql数据库中,目前已成功实现上传并将数据读出来,但是在批量插入数据时出现错误(无法执行SQL语句),但用输出的$sql的值的语句直接在pgAdminIII中运行,又是成功的。哪位大神帮助看一下,不胜感激!

<?phpinclude_once("reader.php");include_once("conn.php");$remotefilename= date("Ymdhis").".xls";if (substr($_FILES["file"]["name"],-4)==".xls"){  if ($_FILES["file"]["error"] > 0)    {    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";    }  else    {     if(move_uploaded_file($_FILES["file"]["tmp_name"],"xlstmp/" .$remotefilename)==1)	 {	    //上传成功并开始读取xls文件		$data = new Spreadsheet_Excel_Reader();        $data->setOutputEncoding('CP936');		$data->read("xlstmp/" .$remotefilename);		$count=0;		if($data->sheets[0]['numRows']>=2 && $data->sheets[0]['numCols']>=2)		{			for ($i = 2; $i <= $data->sheets[0]['numRows']; $i++)			{			$s="";			for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++)				{				if(strlen($data->sheets[0]['cells'][$i][$j])==0) break;				$s.= $data->sheets[0]['cells'][$i][$j]."|";				}			 if(strlen($s)!=0)				{				 $count++;				$ss =explode('|',$s);//将关键词以空格分割到数组中。								// $sql="INSERT INTO zikao_tzd_kecheng(\"KC_DM\",\"KC_MC\")  VALUES('1111','ok')";//执行上面这句都是可以的				 $sql="INSERT INTO zikao_tzd_kecheng(\"KC_DM\",\"KC_MC\")  VALUES('".$ss[0]."','".$ss[1]."')";//执行上面这句就不成功。				// $sql="INSERT INTO zikao_tzd_kecheng(\"KC_DM\",\"KC_MC\")  VALUES('".$data->sheets[0]['cells'][$i][1]."','".$data->sheets[0]['cells'][$i][2]."')";				 				 echo $sql."<br>";                 $result = $PG -> query($sql);				 				 }			}			echo $count."records";		}		else		 {			echo "xls's rows or columns is so few.";		 }	}	 else         echo "upload failed.";    } }else  {  echo "invalid file";  }   $PG ->close();?>

没有错误信息吗

错误提示就是:The database query fail
可我直接用调试时输出的$sql的值直接在pgAdminIII中执行,又是成功插入数据的。
如:INSERT INTO zikao_tzd_kecheng("KC_DM","KC_MC") VALUES('3708','中国近现代史纲要')
但VALUES中使用从Excel可读出来的变量又不行。

// $sql="INSERT INTO zikao_tzd_kecheng(\"KC_DM\",\"KC_MC\") VALUES('1111','ok')";
//执行上面这句都是可以成功插入的
$sql="INSERT INTO zikao_tzd_kecheng(\"KC_DM\",\"KC_MC\") VALUES('".$ss[0]."','".$ss[1]."')";
//但上面这句用变量$ss[0],$ss[1]就插入不成功,提示The database query fail

echo pg_last_error($PG); 看看

echo $sql;
贴出结果看看

这是echo $sql的结果。

你这个应该是页面编码的问题。中文可能乱码了。
mysql_query('set names utf8')

的确如lang11zi 所说,我把需要写入的字符串转化为 utf8就ok了。因为字符串是从 Excel读出来的,默认是GB2312。
谢谢以上各位的解答。散分。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

What is REST API design principles? What is REST API design principles? Apr 04, 2025 am 12:01 AM

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

How do you handle exceptions effectively in PHP (try, catch, finally, throw)? How do you handle exceptions effectively in PHP (try, catch, finally, throw)? Apr 05, 2025 am 12:03 AM

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

What are anonymous classes in PHP and when might you use them? What are anonymous classes in PHP and when might you use them? Apr 04, 2025 am 12:02 AM

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.

What is the difference between include, require, include_once, require_once? What is the difference between include, require, include_once, require_once? Apr 05, 2025 am 12:07 AM

In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.

Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error). Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error). Apr 08, 2025 am 12:03 AM

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.
