我想在html中显示一段文本（存储在SQL表中）。 我遇到的问题是，当网页上显示所有换行符时，它们都会被删除。
文字如下：
第1天，
这是第一天。
这一天终于完成了。
它会显示如下：
第1天，这是第一天。这一天终于完成了。
代码是
$result = mysqli_query($conn, "SELECT tablea.id, tableb.id, tablea.name, tablea.surn, tableb.messg, tableb.tdate, tableb.person, FROM tablea INNER JOIN msgs ON tablea.id=tableb.id WHERE id=$id ORDER BY tdate ASC")
or die(mysqli_error($conn));
while($row = mysqli_fetch_array( $result )) {
?>
<div>
<div>
<p>
<?php echo strtoupper($row["person"]); ?>
</p>
<p>
<?php echo $row["messg"]; ?>
</p>
<p>
<?php echo $row["tdate"]; ?>
</p>
</div>
</div>

使用 init: function () {
var app = Consumer.create({
queueUrl: Settings.getSetting("sendgrid-aws-sqs-queue"),
batchSize: 1,
visibilityTimeout: 30,
waitTimeSeconds: 20,
sqs: MarvelAWS.sqs,
handleMessage: function (message, done) {
try {
var msgBody;
try {
msgBody = JSON.parse(message.Body);
} catch (err) {
msgBody = null;
this._warn("parsing error handling SQS queue " + err, msgBody);
}
var environment = Settings.getSetting('environment');
if (validateMsg(msgBody) && (environment !== "prod" || this.LIST_TO_ID[msgBody.listId.toString()])) {
var userProfile = msgBody.profile,
timeSent = msgBody.timeSent,
action = msgBody.action,
listId = msgBody.listId.toString(),
suppressionListId = msgBody.suppressionListId.toString();
_.each(this.actionsMap[action], function (oneAction) {
this._debug(oneAction + ':' + listId + ' ' + msgBody.profile.email);
sendgridQueueManager.createQueue({
action: oneAction
});
sendgridQueueManager.push({
action: oneAction,
listId: listId,
suppressionListId: suppressionListId,
timeSent: timeSent,
profile: userProfile
});
}.bind(this));
EngineMonitor.countOperation(EngineMonitor.OPS.SENDGRID_SQS_QUEUE_PULL_SUCCESS);
} else {
this._warn("validation error", msgBody);
EngineMonitor.countOperation(EngineMonitor.OPS.SENDGRID_SQS_QUEUE_PULL_ERROR);
}
done();
} catch (err) {
this._warn("error_processing_message " + err);
done(new Error('error processing message'));
}
}.bind(this)
});
app.on("message_received", function () {
this._debug("message_received");
EngineMonitor.countOperation(EngineMonitor.OPS.SENDGRID_SQS_QUEUE_MESSAGE_RECEIVED);
}.bind(this));
app.on("message_processed", function () {
this._debug("message_processed");
EngineMonitor.countOperation(EngineMonitor.OPS.SENDGRID_SQS_QUEUE_MESSAGE_PROCESSED);
}.bind(this));
app.on("error", function (err, message) {
this._warn("message_error " + err + " " + message);
EngineMonitor.countOperation(EngineMonitor.OPS.SENDGRID_SQS_QUEUE_PULL_ERROR);
}.bind(this));
app.on("processing_error", function (err, message) {
this._warn("processing_error " + err);
EngineMonitor.countOperation(EngineMonitor.OPS.SENDGRID_SQS_QUEUE_PULL_ERROR);
}.bind(this));
app.start();
this._debug('sqs_app_start');
},
函数将换行符转换为HTML换行符（＆lt; br /＆gt;）。
