php操作csv文件代码实例汇总 - 摘要: 本文讲的是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:$sales = array( array('Northeast', '2004-01-01', '2004-02-01', 12.54), array('Northwest',

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
$fp = fopen('sample3.csv', 'r') or die("can't open file");print "<table>/n";while($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."<br>";}
