Question

我在写入基本文本文件中的新行时遇到了困难。所有其他文本（包括逗号）看起来都很好，但没有新行（没有空格或任何东西）。我非常感谢任何方向。

<?php 
session_start();
$user = $_SESSION['store'];

function format($input) {
$input = trim($input);
$input = stripcslashes($input);
$input = htmlspecialchars($input);
return $input;

}

$file = "messages/reminder.txt";
$image;
$secFreqLabel;
$freqLabel;
$uploadDirectory = "corpImages/";

if(!file_exists($file)) {
$temp = fopen($file, "w"); // create file
fclose($temp);
}

 $con = new PDO("sqlite:bk.db");
if($_SERVER['REQUEST_METHOD'] == "POST") {
$secFreqLabel =  'reminder.jpg';
$freqLabel =  'reminderHourly.jpg';
$thirdFreqLabel =  'reminderThree.jpg';
$fourthFreqLabel =  'reminderFour.jpg';

$freqUploadFile = $uploadDirectory . $freqLabel;
$secFreqUploadFile = $uploadDirectory . $secFreqLabel;
$thirdFreqUploadFile = $uploadDirectory . $thirdFreqLabel;
$fourthFreqUploadFile = $uploadDirectory . $fourthFreqLabel;

$statement = $con->prepare("INSERT INTO slides (image, label) VALUES (:image, :label)");

if(!empty($_FILES['freqImage'])) {
$con->exec("DELETE FROM slides where label = 'reminder.jpg'");
}

if(!empty($_FILES['secFreqImage'])) {
$con->exec("DELETE FROM slides where label = 'reminderHourly.jpg'");
}

if(!empty($_FILES['thirdFreqImage'])) {
$con->exec("DELETE FROM slides where label = 'reminderThree.jpg'");
}

if(!empty($_FILES['fourthFreqImage'])) {
$con->exec("DELETE FROM slides where label = 'reminderFour.jpg'");
}

$image = file_get_contents($_FILES['freqImage']['tmp_name']);
move_uploaded_file($_FILES['freqImage']['tmp_name'], $freqUploadFile);
$statement->bindParam(":label", $freqLabel);
$statement->bindParam(":image", $image);
$statement->execute();

$image = file_get_contents($_FILES['secFreqImage']['tmp_name']);
move_uploaded_file($_FILES['secFreqImage']['tmp_name'], $secFreqUploadFile);
$statement->bindParam(":label", $secFreqLabel);
$statement->bindParam(":image", $image);
$statement->execute();

$image = file_get_contents($_FILES['thirdFreqImage']['tmp_name']);
move_uploaded_file($_FILES['thirdFreqImage']['tmp_name'], $thirdFreqUploadFile);
$statement->bindParam(":label", $thirdFreqLabel);
$statement->bindParam(":image", $image);
$statement->execute();

$image = file_get_contents($_FILES['fourthFreqImage']['tmp_name']);
move_uploaded_file($_FILES['fourthFreqImage']['tmp_name'], $fourthFreqUploadFile);
$statement->bindParam(":label", $fourthFreqLabel);
$statement->bindParam(":image", $image);
$statement->execute();

$text = format($_POST['freq']) . "," . format($_POST['freqMessage']) . "\n" . format($_POST['secFreq']) . "," . format($_POST['secFreqMessage']) . "\n" . format($_POST['thirdFreq']) . "," . format($_POST['thirdFreqMessage']) . "\n" . format($_POST['fourthFreq']) . "," . format($_POST['fourthFreqMessage']);

$writer = fopen($file, "w");
fwrite($writer, $text);
fclose($writer);

touch("update.txt");
}

$handler = fopen($file, "r");

$firstReminder = fgetcsv($handler, ",");
$secondReminder = fgetcsv($handler, ",");
$thirdReminder = fgetcsv($handler, ",");
$fourthReminder = fgetcsv($handler, ",");
fclose($handler);


?>

而不是使用\n使用常量调用PHP_EOL代表根据您的环境的行尾。

PHP_EOL（string）正确的行结束＆＃39;这个平台的象征。自PHP 5.0.2起可用

$text = format($_POST['freq']) . "," . format($_POST['freqMessage']) . PHP_EOL . format($_POST['secFreq']) . "," . format($_POST['secFreqMessage']) . PHP_EOL . format($_POST['thirdFreq']) . "," . format($_POST['thirdFreqMessage']) . PHP_EOL . format($_POST['fourthFreq']) . "," . format($_POST['fourthFreqMessage']);

Windows中的

PHP_EOL将为CR+LF，并且位于unix系统中LF

CR - 回程，U + 000D
LF - 换行，U + 000A

PHP - 编写新行的困难
