有时写程序时后台要求把大量数据导入数据库中,比如计算机考试成绩的查询、电话簿的数据等一般都是存放在excel中的,这时我们可把数据导出成csv文件,然后通过以下程序即可在后台批量导入数据到数据库中.

下面只是主要程序部分,代码如下:

<?php  
	/***************************************** 
	**********作者:冲星/arcow**************** 
	**********njj@nuc.edu.cn******************* 
	**********php导入csv文件到数据库********** 
	**********同时计算程序执行时间*********** 
	**********www.phprm.com*********** 
	****************************************/ 
	//定义获取时间函数  
	function getmicrotime(){  
	    list($usec, $sec) = explode(" ",microtime());  
	    return ((float)$usec + (float)$sec);  
	} 
	 
	<?php 
	$time_start = getmicrotime(); 
	include("db.inc.php");//连接数据库 
	$db=new testcsv; 
	 
	 
	<?php 
	$handle = fopen ("test.csv","r"); 
	$sql="insert into scores(idcard,names,num,sex,nation,score) values(&#39;"; 
	while ($data = fgetcsv ($handle, 1000, ",")) { 
	   $num = count ($data); 
	   for ($c=0; $c < $num; $c++) { 
	       if($c==$num-1){$sql=$sql.$data[$c]."&#39;)";break;} 
	       $sql=$sql.$data[$c]."&#39;,&#39;"; 
	   } 
	print "<br>"; 
	echo $sql."<br>"; 
	$db->query($sql); 
	echo "SQL语句执行成功!<br>"; 
	$sql="insert into scores(idcard,names,num,sex,nation,score) values(&#39;";//开源代码phprm.com 
	} 
	fclose ($handle); 
	$time_end = getmicrotime(); 
	$time = $time_end - $time_start; 
	echo "程序执行时间:".$time."秒";
