[英]How to remove blank line in CSV file in php
我試圖從xml文件中獲取數據然后將其寫入CSV文件。在生成的文件中,它在每個記錄后放了這么多空行。
<?php
header("Content-Type: application/vnd.ms-excel");
header("Content-disposition: attachment; filename=spreadsheet.xls");
$url = 'test.xml'; // xml file location with file name
if (file_exists($url)) {
$xml = simplexml_load_file($url);
echo 'item_no' . "\t" . 'description' . "\t" . 'price' . "\t" . 'base_qty' . "\t" . 'var_qty' . "\t" . 'base_price_1' . "\t\n";
foreach ($xml->record as $books) {
$array_count = count($books);
for ($key = 0; $key < $array_count; $key++) {
echo $books->item_no[$key]."\t" . $books->description[$key]."\t" . $books- >price[$key]."\t" . $books->base_qty[$key] . "\t" . $books->var_qty[$key] . "\t" . $books->base_price_1[$key] . "\t" . "\n";
}
}
}
?>
確保\\n
未在最后一條記錄中打印
<?php
header("Content-Type: application/vnd.ms-excel");
header("Content-disposition: attachment; filename=spreadsheet.xls");
$url = 'test.xml'; // xml file location with file name
$output = "";
if (file_exists($url)) {
$xml = simplexml_load_file($url);
$output.= 'item_no' . "\t" . 'description' . "\t" . 'price' . "\t" . 'base_qty' . "\t" . 'var_qty' . "\t" . 'base_price_1' . "\t\n";
foreach ($xml->record as $books) {
$array_count = count($books);
for ($key = 0; $key < $array_count; $key++) {
$output.= $books->item_no[$key]."\t" . $books->description[$key]."\t" . $books- >price[$key]."\t" . $books->base_qty[$key] . "\t" . $books->var_qty[$key] . "\t" . $books->base_price_1[$key] . "\t" . "\n";
}
}
echo rtrim($output);
}
?>
