Question

i need to find all uppercase words in a string and set it bold

$_POST[\'descricao\'] = \"UPPERCASE test WORD\"
$_POST[\'descricao\'] = preg_replace(\"\\b[A-Z]{2,         


        

Answer 1

You need to capture the group and enclose the pattern:

preg_replace("/\b([A-Z]{2,})\b/", "<b>\\1</b>", $_POST['descricao']);

Answer 2

Use this:

$_POST['descricao'] = "UPPERCASE test WORD"
$_POST['descricao'] = preg_replace("/\b([A-Z]{2,})\b/", "<b>$1</b>", $_POST['descricao']);
