如何在PHP文件中添加带有文本的新行？

Question

OS: Ubuntu/Xfce, 14.04.

I have tried a bunch of solutions, but none of them worked for me. I know that "/n", PHP_EOL, or "/n/r" should add a new line. A form script from another file is suppose to add whatever was typed into a new line. It won't go into a new line, just the first line.

Here is my code:

$fp = fopen($_SERVER['DOCUMENT_ROOT']. "/HDdeltin/LoginSignup/Users/$con", "wb");
fwrite($fp,$text);
$writeemail = $email . "\n";
fwrite($fp,$writeemail);
fclose($fp);

What is wrong with the code? Thanks

Answer 1

You can try by using

$writeemail = $email . PHP_EOL;

or

$writeemail = $email . '</br>';

Answer 2

Try adding something like

 "<br/>".PHP_EOL.

br is the html line break tag.

PHP_EOL actually adds a newline in the source code which is not displayed by html rendering angines.

If I've read your question right, you want to add a new line to the file and not overwrite it. My question would be, why are you still using PHP4 functions? Use PHP5 functions, since they're better, easier to use and more comfortable. Use this:

file_put_contents($_SERVER['DOCUMENT_ROOT']. "/HDdeltin/LoginSignup/Users/$con", "\n".$email, FILE_APPEND);

If you're already on a new line (because you already append a new line to your string before you've written it to your file), move "\\n" to the other side of $email.
