Find the тэг <p> с любыми аттрибутами , replace with то что нашли + дополнительный текст :

 $ php -r "echo preg_replace('/(<p[^>]*>)/', '\$1foo', '<p><strong>текст</strong></p>') . PHP_EOL;" <p>foo<strong>текст</strong></p>
  • Almost, but the problem is that there are many such tags and unique in relation to others only its content. Габаритные размеры (мм) (ШхГхВ): 1000х1000х1000 - Timofey Semenyuk
  • then this is /(<p[^>]*>)/ change to /(<p[^>]*>)(уникальный-текст-детектор)/ . Add the same text in the second argument as $2 . and even better update the question, because Now his production does not reflect these of your nuances. - Lexx918
