$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. 讀取csv數(shù)據(jù), 使用特殊的流輸出

$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. 讀取csv數(shù)據(jù), 輸出到緩沖中

$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. 讀取csv文件的數(shù)據(jù)

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

5. 下載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('中國(guó)', '2004-01-01', '2004-02-01', 945.21),
);

$fh = fopen('php://output', 'w') or die("can't open php://output");
$total = 0;

// 告訴瀏覽器發(fā)送的是一個(gè)csv文件
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="sales.csv"');

// 輸出表頭
fputcsv($output, array('Region', 'Start Date', 'End Date', 'Amount'));
// 輸出每一行數(shù)據(jù), 并遞增$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, array('All Regions', '--', '--', $total));

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

6.讀取CSV文件指定行和區(qū)間行

/*****讀取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);//輸入第10行內(nèi)容


/*****讀取CSV文件中的區(qū)間行*****/
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讀取并輸出第11行到第20行

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