php读写csv文件的五个实例

发布时间:2020-06-26编辑:脚本学堂
在php中读写csv文件经常遇到,这里分享几个php读取csv文件的例子,有需要的朋友参考下。

例1,读取csv数据, 输出到sales.csv文件中
 

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), 
); 
 
$fh = fopen('sales.csv', 'w') or die("Can't open sales.csv"); 
foreach($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($output, array('Region', 'Start Date', 'End Date', 'Alinuxjishu/9952.html target=_blank class=infotextkey>mount')); 
// 输出每一行数据, 并递增$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");
