Share: Three ways to remove carriage return and line feed in PHP

 //php line breaks in different systems
//The implementation of line breaks is different between different systems
///n is used in linux and unix
///r is used in MAC // bbs.it-home.org
//window In order to reflect the difference from Linux, it is /r/n
//So the implementation methods are different on different platforms
//php There are three ways to solve it

//1. Use str_replace to replace newlines
$str = str_replace(array("/r/n", "/r", "/n"), "", $str);

//2. Use regular replacement
$str = preg_replace('//s*/', '', $str);

//3. Use variables defined by PHP (recommended)
$str = str_replace(PHP_EOL, '', $str);
