php操作csv文件代码实例汇总

1.读取csv数据,输出到sales.csv文件中：

PHP;"> $sales = array( array('Northeast','2004-01-01','2004-02-01',12.54),array('Northwest',546.33),array('Southeast',93.26),array('Southwest',945.21),array('All Regions','---','--',1597.34),);

$fh = fopen('sales.csv','w') or die("Can't open sales.csv");
foreach($sales as $sales_line){
if(fputcsv($fh,$sales_line) === false){
die("Can't write CSV line");
}
}

fclose($fh) or die("Can't close sales.csv");

2. 读取csv数据,使用特殊的流输出

PHP;"> $sales = array( array('Northeast',);

$fh = fopen('PHP://output','w');
foreach($sales as $sales_line){
if(fputcsv($fh,$sales_line) === false){
die("Can't write CSV line");
}
}

fclose($fh);

3. 读取csv数据,输出到缓冲中

PHP;"> $sales = array( array('Northeast',);

ob_start();
$fh = fopen('PHP://output','w') or die("Can't open PHP://output");
foreach($sales as $sales_line){
if(fputcsv($fh,$sales_line) === false){
die("Can't write CSV line");
}
}

fclose($fh) or die("Can't close PHP://output");
$output = ob_get_contents();
ob_end_clean();

4. 读取csv文件的数据

PHP;"> $fp = fopen('sample3.csv','r') or die("can't open file"); print "

5. 下载CSV文件

PHP;"> $sales = array( array('Northeast',array('中国','w') or die("can't open PHP://output"); $total = 0;

// 告诉浏览器发送的是一个csv文件
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="sales.csv"');

// 输出表头
fputcsv($output,array('Region','Start Date','End Date','Amount'));
// 输出每一行数据,并递增$total
foreach($sales as $sales_line){
if(fputcsv($fh,$sales_line) === false){
die("Can't write CSV line");
}else{
$total += $sales_line[3];
}
}

fputcsv($fh,$total));

fclose($fh) or die("Can't close PHP://output");

6.读取CSV文件指定行和区间行

PHP;"> /*****读取CSV文件中的指定行*****/ function get_file_line_a($file_name,$line){ $n = 0; $handle = fopen($file_name,'r'); if ($handle) { while (!feof($handle)) { ++$n; $out = fgets($handle,4096); if($line==$n) break; } fclose($handle); } if( $line==$n) return $out; return false; }

echo get_file_line("windows_2011_s.csv",10);//输入第10行内容

/读取CSV文件中的区间行/
function get_file_line_b( $file_name,$line_star,$line_end){
$n = 0;
$handle = fopen($file_name,"r");
if ($handle) {
while (!feof($handle)) {
++$n;
$out = fgets($handle,4096);
if($line_star <= $n){
$ling[] = $out;
}
if ($line_end == $n) break;
}
fclose($handle);
}
if( $line_end==$n) return $ling;
return false;
}

//用 get_file_line读取并输出第11行到第20行

$aa = get_file_line("windows_2011_s.csv",11,20); //从第11行到第20行
foreach ($aa as $bb){
echo $bb."
";
}
