blocks|key|905750|text|如果不看你的代码，我不能确定，但我猜你使用的是单引号('\n')而不是双引号("\n")。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|905751|PHP只会在字符串括在双引号中时计算转义序列。如果你使用'\n'，PHP会把它当作一个文字字符串。如果您使用"\n"，PHP将解析字符串中的变量和转义序列，并按照您的期望打印一个新行。|905752|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Without seeing your code I cannot be sure, but my guess is you are using single quotes ('\n') instead of double quotes ("\n").

PHP will only evaluate escape sequences if the string is enclosed in double quotes. If you use '\n', PHP will just take that as a literal string. If you use "\n", PHP will parse the string for variables and escape sequences and print a new line like you are expecting.

blocks|key|1120800|text|Alay+Geleynse说的是对的，我和你有同样的问题，问题是由于转义字符(\r，\n)的存在。为了对变量进行“非转义”，我使用了$var+=+stripcslashes($var)，它被正确地显示出来|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1120801|entityMap^0|1U|Q|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

What Alay Geleynse said was right, I had the same problem as you and the issue was due to the escape characters (\r, \n) was there. To 'unescaped' the variable I used <code>$var = stripcslashes($var)</code> and it's shown correctly

blocks|key|906103|text|我也遇到过类似的问题，我的解决方案是对换行符进行双重转义。\n|type|unstyled|depth|inlineStyleRanges|entityRanges|data|906104|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had a similar issue and the solution to mine was double-escaping the newline character.

How do you create a new line in a textarea when inserting the text via php?

I thought it was <code>\n</code> but that gets literally printed in the textarea.

Thanks

php :: new line in textarea?

如何在通过php插入文本时在文本区域中创建新行？我以为它是\n，但它被直接打印在文本区。谢谢
