PHP等同于VB.net字符代码

Question

So I am calling an API written in VB.NET from PHP and passing it some text. I want to insert into that text two linebreaks.

I understand that in VB.NET, the character codes for a linebreak are Chr(10) and Chr(13) . How can I represent those in PHP?

TIA.

Answer 1

The chr function exists in PHP too.

But, generally, we use " \\n " (newline ; chr=10) and " \\r " (carriage-return ; chr=13) (note the double-quotes - do not use simple quotes here, is you want those characters)

For more informations, and a list of the escape sequences for special characters, you can take a look at the manual page about strings .

Answer 2

• CR or Carriage Return, Chr(10), is represented by \\r in a string
• LF or Line Feed, Chr(13), is represented by \\n in a string

eg

echo "This is\r\na broken line";

this might look more familiar, using the PHP chr() function, but you'd rarely see it done like this:

echo "This is".chr(10).chr(13)."a broken line";

There is also a constant called PHP_EOL which contains the most appropriate line break sequence for the system PHP is running on.

Answer 3

$ break =“ \\ n”;
