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