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

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); $i'.htmlentities($csv_line[$i]).''; print ''; } print "\n"; } print "
'.htmlentities(iconv("gb2312","utf-8",$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$total foreach($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 "; }
