strip_tags() … replace tags by space rather than deleting them

Question

Do you know how to replace html tags with a space character using php?

If I display

strip_tags(\'
Foo
bar\');

Answer 1

I helped my self with example from user40521, but I made a function with same api like php's strip_tags, it does not use multiple variables, and it also makes a trim, so a single whitespace is removed from start / end.

/**
 * @param string $string
 * @param string|null $allowable_tags
 * @return string
 */
function strip_tags_with_whitespace($string, $allowable_tags = null)
{
    $string = str_replace('<', ' <', $string);
    $string = strip_tags($string, $allowable_tags);
    $string = str_replace('  ', ' ', $string);
    $string = trim($string);

    return $string;
}
