php读写csv文件的五个实例
发布时间：2017-08-24 编辑：jiaochengji.com
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");
$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);
$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();
$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");
$fp = fopen('sample3.csv', 'r') or die("can't open file");
print "<table>\n";
while($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");
$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");
