[php] Get each line from textarea

<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.

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)

}

Use PHP DOM to parse and add <br/> in it. Like this:

$html = '<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>';

//parsing begins here:
$doc = new DOMDocument();
@$doc->loadHTML($html);
$nodes = $doc->getElementsByTagName('textarea');

//get text and add <br/> then remove last <br/>
$lines = $nodes->item(0)->nodeValue;

//split it by newlines
$lines = explode("\n", $lines);

//add <br/> at end of each line
foreach($lines as $line)
    $output .= $line . "<br/>";

//remove last <br/>
$output = rtrim($output, "<br/>");

//display it
var_dump($output);

This outputs:

string ' put returns between paragraphs
<br/>for linebreak add 2 spaces at end
<br/>indent code by 4 spaces
<br/>quote by placing > at start of line
' (length=141)

For a <br> on each line, use

<textarea wrap="physical"></textarea>

You will get \ns in the value of the textarea. Then, use the nl2br() function to create <br>s, or you can explode() it for <br> or \n.

Hope this helps

Old tread...? Well, someone may bump into this...

Rather than using:

$values = explode("\n", $value_string);

Use a safer method like:

$values = preg_split('/[\n\r]+/', $value_string);

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

$array = explode("\n", $text);
for($i=0; $i < count($array); $i++)
{
    echo $line;
    if($i < count($array)-1)
    {
         echo '<br />';
    }
}

$content = $_POST['content_name'];
$lines = explode("\n", $content);

foreach( $lines as $index => $line )
{
    $lines[$index] = $line . '<br/>';
}

// $lines contains your lines
