Get each line from textarea

Question

<textarea> put returns between paragraphs
for linebreak add 2 spaces at end
indent code by 4 spaces
quote by placing > at start of line
</textarea>

$text = value from this textarea;

How to:

1) Get each line from this textarea ($text) and work with them using foreach()?

2) Add <br /> to the end of each line, except the last one?

3) Throw each line to an array.

Important - text inside textarea can be multilanguage.

Have tried to use:

$text = str_replace('\n', '<br />', $text);

But it doesn't work.

Thanks.

Answer 1

You could use PHP constant:

$array = explode(PHP_EOL, $text);

additional notes:
1. For me this is the easiest and the safest way because it is cross platform compatible (Windows/Linux etc.)
2. It is better to use PHP CONSTANT whenever you can for faster execution

Answer 2

It works for me:

if (isset($_POST['MyTextAreaName'])){
    $array=explode( "\r\n", $_POST['MyTextAreaName'] );

now, my $array will have all the lines I need

    for ($i = 0; $i <= count($array); $i++) 
    {
        echo (trim($array[$i]) . "<br/>");
    }

(make sure to close the if block with another curly brace)

}
