php讀寫csv文件的五個實例

讀取csv數據, 輸出到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，讀取csv數據, 使用特殊的流輸出

<?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，讀取csv數據, 輸出到緩沖中 
 
復制代碼 代碼示例:
<?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，讀取csv文件的數據 
 
復制代碼 代碼示例:
<?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，下載的CSV文件 
 
復制代碼 代碼示例:
<?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('中國', '2004-01-01', '2004-02-01', 945.21),  
);  
  
$fh = fopen('php://output', 'w') or die("can't open php://output");  
$total = 0;  
  
// 告訴瀏覽器發送的是一個csv文件  
header('Content-Type: application/csv');  
header('Content-Disposition: attachment; filename="sales.csv"');  
  
// 輸出表頭  
fputcsv($output, array('Region', 'Start Date', 'End Date', 'Amount'));  
// 輸出每一行數據, 並遞增$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");
