Regex '''string''' to <b>string</b>

Question

I need a regex to replace '''string''' with <b>string</b>

this one wont work: '/'''(.*?)'''/'

Answer 1

Make sure to escape the single quotes with backslashes:

'/\'\'\'(.*?)\'\'\'/'

Or just use double quotes in which case you don't have to worry about escaping single quotes:

"/'''(.*?)'''/"

Answer 2

$string = "guns '''hurt''' people";

echo preg_replace ("/'''(.*)'''/", '<b>$1</b>', $string);
