php str_replace input box carriage return replacement br_PHP tutorial

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

Copy code

代码如下	复制代码
function htmtocode($content) {     $content = str_replace("n", " ", str_replace(" ", " ", $content));     return $content; }

function htmtocode($content) {

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

}

代码如下	复制代码
function htmtocode($content) {     $content = str_replace(" ", " ", $content);     $content = str_replace("n", " ",$content);       return $content; }

Replace the spaces first, then the carriage returns.

function htmtocode($content) { $content = str_replace(" ", " ", $content); $content = str_replace("n", " ",$content); Return $content; }
