Question

我在codeignitor中使用“ fputcsv”编写了一个csv文件。我有两个数组形式的表，它们确实写在了csv文件中。

现在，我想在csv文件中插入一些空白行，作为两个表之间的分隔符。

$this->load->helper('download');

$blanks = array("\t","\t","\t","\t");

$fp = fopen('php://output', 'w');
foreach ($writedata as $fields) { //table one
fputcsv($fp, $fields);
}

for($i=0;$i<5;$i++)
{
foreach ($blanks as $fields) { //blank space insertion try
fputcsv($fp, $fields);
}
}

foreach ($table2 as $fields) { //table two
fputcsv($fp, $fields);
}
$data = file_get_contents('php://output');
$name = 'data.csv';

尝试了其他版本的空白，并尝试将其插入，但没有用。

尝试一下：

<?php

$this->load->helper('download');

$fp = fopen('php://output', 'w');
foreach ($writedata as $fields) { //table one
    fputcsv($fp, $fields);
}

for($i=0;$i<5;$i++) {
    fput($fp, PHP_EOL);
}

foreach ($table2 as $fields) { //table two
    fputcsv($fp, $fields);
}
$data = file_get_contents('php://output');
$name = 'data.csv';

或

$this->load->helper('download');

$blanks = array("\t","\t","\t","\t");

$fp = fopen('php://output', 'w');
foreach ($writedata as $fields) { //table one
    fputcsv($fp, $fields);
}

for($i=0;$i<5;$i++) {
    fputcsv($fp, $blanks);
}

foreach ($table2 as $fields) { //table two
    fputcsv($fp, $fields);
}
$data = file_get_contents('php://output');
$name = 'data.csv';

这有效。请原谅缩进。有了这个，我总是可以自定义我想要空白行的方式。

$this->load->helper('download');

$blanks = array();
for($i=0;$i<5;$i++)
    {
    array_push($blanks,array("\t","\t","\t","\t");
    }

$fp = fopen('php://output', 'w');
foreach ($writedata as $fields) {
   fputcsv($fp, $fields);
}

foreach ($blanks as $fields) {
    fputcsv($fp, $fields);
}

foreach ($table2 as $fields) {
    fputcsv($fp, $fields);
}
$data = file_get_contents('php://output');
$name = 'data.csv';

使用php编写时将空白行插入到csv文件中？
