PHP gets the value of textarea and handles the method of carriage return, textarea carriage return line

This example describes how PHP gets the value of the textarea and handles the carriage return line-wrapping method. Share to everyone for your reference. The implementation method is as follows:

In general, in the HTML form textarea we press Enter and line wrapping are some ASCII or special character encoding, if not to convert the output text is not typesetting.

PHP gets textarea value is very simple textarea carriage return behavior \ r \ n See example below
HTML code:

Copy the Code code as follows:
PHP Code:

Copy the Code code as follows: $str =$_get[' Test '];
echo $str. '
';
$arr =explode ("\ n", $str);
Print_r ($arr);
echo Count ($arr). '
';//Carriage return number
$str 1=nl2br ($STR);//carriage return for newline

All code:

Copy the Code code as follows:





<?php

';
$arr =explode ("\ n", $str);
Print_r ($arr);
echo Count ($arr). '
';//Carriage return number
$str 1=nl2br ($STR);//carriage return to a newline default function
echo $str 1;
?>


Take another look at the DZ Forum example. Not much to say, directly on the code:

Copy the code as follows: $names = Preg_split ('/\r\n/', $_post[' textarea ']);
foreach ($names as $name) {
Todo something Eg:echo $name;
}
The value is very simple, so assignment, output line break in textarea is not that simple

Copy the Code code as follows: $vals = Get_from_mydb ();
$tmp = ";
foreach ($vals as $val) {
$tmp. = $val. ";
}
"and" "What does that mean?"
I believe we all see, in fact, textarea in the carriage return into a character is "\ n", so the PHP processing textarea in the carriage is actually processing characters in the "\ n".

I hope this article is helpful to everyone's PHP programming.
