這篇文章主要介紹了php操作csv文件代碼實例匯總,本文給出6個操作CSV文件的代碼實例,包括讀取、寫入、讀取指定區間等,需要的朋友可以參考下
1.讀取csv數據, 輸出到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. 讀取csv數據, 使用特殊的流輸出
$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. 讀取csv數據, 輸出到緩沖中
$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. 讀取csv文件的數據
$fp = fopen('sample3.csv', 'r') or die("can't open file");
print "<table>/n";
while($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");
5. 下載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, 并遞增$total
foreach($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");
6.讀取CSV文件指定行和區間行
/*****讀取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);//輸入第10行內容
/*****讀取CSV文件中的區間行*****/
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 <= $n){
$ling[] = $out;
}
if ($line_end == $n) break;
}
fclose($handle);
}
if( $line_end==$n) return $ling;
return false;
}
//用 get_file_line讀取并輸出第11行到第20行
$aa = get_file_line("windows_2011_s.csv", 11, 20); //從第11行到第20行
foreach ($aa as $bb){
echo $bb."<br>";
}
