1.读取csv数据, 输出到sales.csv文件中：

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

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

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

$fp = fopen('sample3.csv', 'r') or die("can't open file");print "\n";while($csv_line = fgetcsv($fp)){  print '';  for($i=0, $j=count($csv_line); $i<$j; $i++){    // print '';      print '';  }  print "\n";}print "
'.htmlentities($csv_line[$i]).'
'.htmlentities(iconv("gb2312","utf-8",$csv_line[$i])).'
\n";fclose($fp) or die("can't close file");

5. 下载CSV文件

$sales = array(  array('Northeast', '2004-01-01', '2004-02-01', 12.54),  array('Northwest', '2004-01-01', '2004-02-01', 546.33),  array('Southeast', '2004-01-01', '2004-02-01', 93.26),  array('Southwest', '2004-01-01', '2004-02-01', 945.21),  array('中国', '2004-01-01', '2004-02-01', 945.21),);$fh = fopen('php://output', '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$totalforeach($sales as $sales_line){  if(fputcsv($fh, $sales_line) === false){    die("Can't write CSV line");    }else{    $total += $sales_line[3];    }}fputcsv($fh, array('All Regions', '--', '--', $total));fclose($fh) or die("Can't close php://output");

6.读取CSV文件指定行和区间行

/*****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."
";}
