这是用于将数据导出到.csv文件以保存数据的php的MWE，我希望每个提交表单我想要在换行符中打印数据
<?php
$fieldAA = $_POST[" "];
$fieldA = $_POST["textnames"];
$fieldB = $_POST["fathername"];
$fieldC = $_POST["mothername"];
$fieldD = $_POST["institute"];
$fieldE = $_POST["category"];
$fieldF = $_POST["sex"];
$fieldG = $_POST["stream"];
$fieldH = $_POST["core-1"];
$fieldI = $_POST["core-2"];
$fieldJ = $_POST["elective-1"];
$fieldK = $_POST["elective-2"];
$fieldL = $_POST["elective-3"];
$fieldM = $_POST["elective-4"];
$fieldN = $_POST["compulsory"];
$keys = array($fieldAA,$fieldA,$fieldB,$fieldC,$fieldD,$fieldE,$fieldF,$fieldG,$fieldH,'','',$fieldI,'','',$fieldJ,'','',$fieldK,'','',$fieldL,'','',$fieldM,'','',$fieldN,''); //THIS IS WHERE YOU PUT THE FORM ELEMENTS ex: array('$fieldA','$fieldB',etc)
$csv_line = $keys;
foreach( $keys as $key ){
array_push($csv_line,'' . $_GET[$key]);
}
$fname = 'data.csv'; //NAME OF THE FILE
$csv_line = implode(',',$csv_line);
if(!file_exists($fname)){$csv_line = "\r\n" . $csv_line ;}
$fcon = fopen($fname,'a');
$fcontent = $csv_line ;
fwrite($fcon,$csv_line);
fclose($fcon);
echo "Successfully done! $keys[1]"
?>

在php中我们可以使用PHP_EOL来回显一行的结尾，使用此方法将不依赖于当前文档/平台的行结尾。
实施例： -
$string = "I want a new line here" . PHP_EOL . "This is my new line";
csvs中的换行符取决于您用来查看它们的内容。
此外，您可能想要解释MWE在您的问题中的含义。
