Question

I am building an application where users can enter a note into a textarea. The note is then encoded when entered into the database. When I decode the returned value, the nl2br function isn t working. It isn t replacing the with the br tag. When not encoding/decoding text, it works.

我正在使用以下代码对我的信息进行编码/编码:。

如果我进入一个文本领域:

Hello  
World

It encodes it, and then returns when decoded

Hello
World.

I can do a str_replace, but as I come to understand, depending on the browser, a textarea may use or instead of .

Not sure what a good solution is... please help! Thank you!

Answer 1

如果您正在转换成“复制件;文本处理器”,则不使用“复制件”;

If you are converting text to be placed in a text area, use...

str_ireplace("
", "
", $db_string); //or something similar

如果您将案文转换成一个文本领域,则使用......

str_ireplace(array("
", "
", "
"),  <br /> , $db_string);

Separate browsers use whatever, but I believe they all can read just " ". However on a side note, the operating system determines " " vs " ". Just use " ". So replace " " with " ". Or just leave " ", use either, as long as you don t put br tags into your textarea tags you ll be all set.

I have checked your decoded string Hello World. in windows operating system using zend studio 7.2.0. I found nl2br() is working fine in both case and. You should double check your decoded string. May be you are doing addslashes() before encoding it.If so then you have to use stripslashes() before using nl2br().

您可使用<代码>stripslashes($text)来脱覆。然而,我建议说明为什么会增加鞭.。您是否使用<条码>。
