How can I extract the first line of a variable?

[Angry Coder]

Let's say I have the fallowing variable:

$myvar = 'first line
second line
third line';

I need 'first line' in a sperate variable.

Do you know how can I do that?

Thank you.

Well, you should extract the string before "\n".

huh

$line1 = substr($myvar, 0, strpos($myvar, "\n"));

(but make sure you only have \n line breaks)

Your variable doesn't contain any linebreaks as it is. You need to have a ' \n ' in it. Try

<?php
$myvar = "first line\n
second line\n
third line\n";

$lines = explode("\n", $myvar);
echo $lines[0];
?>

HTH

No you don't, that would put 2 line breaks.

PHP does line breaks in multi-line variables.

Ooops, sorry. Ignore my stupidity.
That mistake tells me that I need to stop working now. Have a nice evening.

But you can still use the explode() function with same separator then.
