I want a line break in the #attributes, I've mentioned it in the code as in where I want the line break to be.
$form['advanced_user_data'] = array(
'#type' => 'textarea',
'#attributes' => array('placeholder' => array('"Jack Polard" <jackpolard@xyz.com> (Want a line break here) "Miky Town" <miky@abc.com> (Want a line break here) "Bill Gates" <bill@example.com>')),
'#description' => t('Eg: "Full Name" < emailid@domain.com >'),
);
See this is how it has to be, "\r\n" didnt work, I'm a HTML guy, so I have no knowledge of PHP, please help me in a simpler way.
