我正在从另一个CSV文件中插入所需CSV文件中的数据。
CSV文件正在创建没有任何问题，但它不是在文件中插入数组数据。
它只在第一行插入标题。
以下是我正在尝试的代码：
date_default_timezone_set('America/New_York');
set_time_limit(0);
ini_set("memory_limit", -1);
$realPath = realpath( dirname(__FILE__) );
$path = $realPath.'/3pltracking/';
$files = scandir($path);
$FilePath = $path.$files[2];
$result = array();
$date = date('m-d-Y_his');
if (file_exists($FilePath))
{
if (($handle = fopen($FilePath, "r")) !== FALSE)
{
$i=0;
while (($data = fgetcsv($handle, 10000, ",")) !== FALSE)
{
$i++;
if($i==1) continue;
//$list = array('$data[2],$data[25],$data[4],$data[30],$data[41],$data[27]');
echo $data[2].",".$data[25].",".$data[4].",".$data[30].",".$data[41].",".$data[27];
echo "<br>";
$list = array($data[2].",".$data[25].",".$data[4].",".$data[30].",".$data[41].",".$data[27]);
// the problem is here I believe as it is empty array if I check it outside while loop
}
fclose($handle);
$headers = array('ReferenceNumber', 'TotalCartons', 'ShipCarrier', 'TrackingNum', 'FreightPP', 'TotalWeight');
$fp = fopen($realPath.'\3pltracking\TrackingFiles\Tracking_File_'.$date.'.csv', 'w');
fputcsv($fp, $headers);
foreach ($list as $line) {
$val = explode(",", $line);
fputcsv($fp, $val);
}
fclose($fp);
} else {
$body = "File Not Found";
}
}
这是我的CSV文件数据：

答案 0 :(得分：1)
有很多方法可以解决这个问题......包括str_getcsv($csvData)。不过，我们在这里寻找old-school＆amp;有点扭曲;-)。我们将创建一个使用Regex和Looping构造的函数来构建相关的CSV数据结构。下面的函数说明了如何。另请注意，虽然我们提到这是一种有点扭曲的，老派的方法：不要被愚弄...... 因为它确实存在; - ）。
<?php
$csvSourceFile = __DIR__ . "/1.csv";
$csvPreferredColumns = array('ReferenceNumber', 'TotalCartons', 'ShipCarrier', 'TrackingNum', 'FreightPP', 'TotalWeight');
$newCsvStrut = processCSVData($csvSourceFile, $csvPreferredColumns, __DIR__ . "/test.csv");
/**
* @param $csvSource // PATH TO THE MAIN CSV FILE
* @param array $csvPreferredColumns // ARRAY OF HEADER COLUMN-NAMES TO BE EXTRACTED FROM MAIN CSV
* @param null $newCSVFileName // NAME OF THE NEW CSV FILE TO BE CREATED.

*/
function processCSVData($csvSource, array $csvPreferredColumns, $newCSVFileName=null){
// GET THE CONTENTS OF THE CSV FILE & STORE IT IN A VARIABLE
$csvData = file_get_contents($csvSource);
// SPLIT THE CONTENTS OF THE CSV FILE LINE BY LINE: THAT IS; AT THE END OF EACH LINE
// THUS CONVERTING THE DATA TO AN ARRAY...
$arrCsvLines = preg_split("#\n#", $csvData);

$arrDataMain = $arrDataFinal = array();
// IF THERE IS MORE THAN ONE LINE IN THE ARRAY WE CREATED ABOVE,

if($arrCsvLines && count($arrCsvLines)>0){
// SINCE THE HEADER IS ALWAYS THE FIRST LINE IN THE CHAIN,
// WE EXPLICITLY EXTRACT IT AND STORE IT IN A VARIABLE FOR LATER USE
$arrCsvHeaders = preg_split("#\,([\s\t]+)?#", $arrCsvLines[0]);
// NOW WE LOOP THROUGH ALL THE LINES WE CREATED BY SPLITTING THE CONTENTS
// OF THE CSV FILE AT THE END-OF-LINE BOUNDARY
foreach($arrCsvLines as $key=>$arrCsvLine){
// WE DON'T WANT ANYTHING AT INDEX "0" SINCE IT IS THE HEADER
// AND WE ALREADY DEALT WITH IT ABOVE....
// SO IF THE INDEX $key IS NOT 0, WE CAN CONTINUE PROCESSING
if($key != 0){
$arrDataTemp = array();
$arrTempCsvData = preg_split("#\,([\s\t]+)?#", $arrCsvLine);
foreach($arrTempCsvData as $iKey=>$sData){
