Converting into a new line for use in a text area

Question

If I have a variable:

$var1 = \"Line 1 info blah blah 
 Line 2 info blah blah\";

And a text area:

Answer 1

The answer by @Mobilpadde is nice. But this is my solution with regex using preg_replace which might be faster according to my tests.

echo preg_replace('//i', "\r\n", "testing



");

function function_one() {
    preg_replace('//i', "\r\n", "testing



");
}

function function_two() {
    str_ireplace(['
','
','
'], "\r\n", "testing



");
}

function benchmark() {
    $count = 10000000;
    $before = microtime(true);

    for ($i=0 ; $i<$count; $i++) {
        function_one();
    }

    $after = microtime(true);
    echo ($after-$before)/$i . " sec/function one\n";



    $before = microtime(true);

    for ($i=0 ; $i<$count; $i++) {
        function_two();
    }

    $after = microtime(true);
    echo ($after-$before)/$i . " sec/function two\n";
}
benchmark();

Results:

1.1471637010574E-6 sec/function one (preg_replace)
1.6027762889862E-6 sec/function two (str_ireplace)
