PHP str_replace with wild card?

Question

I know how to use str_replace for simple tasks, like this...

$Header = str_replace(\'
Animals
\', \'
Animals
\', $Heade         


        

Answer 1

You can use the str_replace() technique that has been suggested in the primary comments, but I believe preg_replace() using regular expressions is the best practice for wildcard replacements.

Animals
Plants

EOD;

$str = preg_replace('/
(.*?)<\/h3>/', '
$1
', $str);

echo $str;
