You can add a newline character to a PHP string in the following ways:
- Using the
- Using the Newline Character in a Double-Quoted String;
- Using the
PHP has a built-in constant (
PHP_EOL) for adding newline character. Using this constant will add the correct "End Of Line" character that the platform (PHP is running on) supports (i.e. what the server OS supports). You can use it like so:
$str = 'Foo' . PHP_EOL . 'Bar'; echo $str; // output: // Foo // Bar
Using the Newline Character in a Double-Quoted String
In PHP, only a double-quoted string interprets escape sequences (such as
\n). Therefore, to add a newline character in PHP, you can simply use newline escape sequences (such as
\n) in a double-quoted string, for example, like so:
$str = "Foo\r\nBar"; echo $str; // output: // Foo // Bar
You can specify, for example, the following character codepoints to the
0x0A) — a new line (line feed);
0x0D) — a carriage return.
For example, you can add these characters using codepoints in hexadecimal number format like so:
$str = 'Foo' . chr(0x0D) . chr(0x0A) . 'Bar'; echo $str; // output: // Foo // Bar
Similarly, you can add these characters using codepoints in decimal number format like so:
$str = 'Foo' . chr(13) . chr(10) . 'Bar'; echo $str; // output: // Foo // Bar
chr() function creates a one-character string in a single-byte encoding (such as ASCII, ISO-8859, or Windows 1252).
Please note that the
chr() function is not aware of any string encoding, and cannot be passed a Unicode codepoint value to generate a string in a multibyte encoding such as UTF-8 or UTF-16.
