这篇文章主要介绍了php操作csv文件代码实例汇总,本文给出6个操作CSV文件的代码实例,包括读取、写入、读取指定区间等,需要的朋友可以参考下
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),
- ); //www.phpfensi.com
- $fh = fopen('sales.csv', 'w') or die("Can't open sales.csv");
- foreach($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$total
- foreach($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.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>";
- }
