PHP Convert text box content to HTML format _php tips

This article is an example of how PHP transforms text box content into HTML format. Share to everyone for your reference, specific as follows:

Sometimes we're going to use the HTML format for the content that you enter in a multiline text box to keep the original text formatting, such as wrapping, carriage return, and so on. You can do this by using the following function:

function shtm ($design _str)
{
 $str =trim ($design _str);//get string at the same time to turn tail space and empty carriage return
 //$str =str_replace ("<br > "," ", $str); Remove <br> label
 //$str = "<p>". Trim ($STR);//Add <p>
 $str =str_replace ("\ r \ n", "<br>") to the text header $STR); Replace line breaks
 //$STR with P tags. = "</p>\n";//Text tail add </p>
 $str =str_replace ("<p></p>", "", $str); /Remove empty paragraphs
 $str =str_replace ("\ n", "", $str);//Remove blank lines and line
 $str =str_replace ("</p>", "</p>\n", $str); /Organize HTML code return
 $str;
}
