php读写csv文件的五个实例
读取csv数据, 输出到sales.csv文件中
<?php $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");
例2,读取csv数据, 使用特殊的流输出 复制代码 代码示例: <?php $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); 例3,读取csv数据, 输出到缓冲中 复制代码 代码示例: <?php $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(); 例4,读取csv文件的数据 复制代码 代码示例: <?php $fp = fopen('sample3.csv', 'r') or die("can't open file"); print "<table>\n"; while($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"); 例5,下载的CSV文件 复制代码 代码示例: <?php $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");
