Hola tengo diferentes textos donde aparece la frase "densidad energética:
XXXX kcal/ml." variando el valor de las XXXX. Necesito coger esta parte del
texto para poder enseñarla en la web.

He intentado hacerlo con expresiones regulares peró no me sale, me podeis
ayudar?

El texto:

xxxxxxxxxxxxxxx densidad energética: 1,25% kcal/ml. ccccccccccccccccccccccc

Necesito aislar "densidad energética: 1,25% kcal/ml."

Lo he provado con:

        eregi("densidad energética [A-Za-z]*ml", $t, $row["entradilla"]);
y con
        eregi("densidad energética *[^ml]*ml", $t, $row["entradilla"]);

peró no va
