php str_replace input box carriage return to replace br

When we use textarea, we will find that carriage returns and spaces are not visible, so we use the str_replace function to replace \n in php with br. Friends in need can refer to it. The code is as follows:

function htmtocode ($content) {

$content = str_replace("n", "
", str_replace(" ", " ", $content));

return $content;

}

Replace it first Space, then replace the carriage return, which is equivalent to the following code:

function htmtocode($content) {

  $content = str_replace(" ", " ", $content);

$content = str_replace("n", "
",$content);

return $content;
