Php assigning multiple strings to a single variable

问题

Is there a cleaner way to assign multiple strings to a single variable in php?

I current do like this

<?php
$myStr = '';

$myStr .= 'John';
$myStr .= '<br>';
$myStr .= 'Paul';
$myStr .= '<br>';
$myStr .= 'Ringo';

echo $myStr;
?>

I also use HEREDOC. But are there other ways?

回答1:

If you have to concatenate lot of data, it may be a good idea to use arrays. It's cleaner (not necessarily more memory efficient).

$items = array('Hello', 'How', 'Are', 'You?');
echo implode(' ', $items);

回答2:

It can be done by array and implode() like below

$names = array('John', 'Paul', 'Ringo');
$myStr = implode("<br>", $array);
echo $myStr;
