J'essaye de modifier une chaîne dans mon projet. La chaîne que je modifie contient un paragraphe que l'utilisateur entre, et j'essaie de remplacer des occurrences spécifiques de mots (comme NOM / VERBE), par les noms et les verbes saisis par l'utilisateur. Tout fonctionne parfaitement, sauf que j'essaie de faire en sorte que la police des noms et des verbes saisis par l'utilisateur soit en gras, mais je ne peux pas savoir où mettre le texte en gras. Toutes les suggestions ou pointeurs seraient grandement appréciés.

J'ai tenté de modifier les chaînes à l'intérieur de $ stringParagraph avec la commande str_replace mais je n'ai pas réussi. En bref, tout ce que j'essaye de faire est d'afficher le contenu de $ stringParagraph à l'utilisateur, le contenu de $ stringFirstNoun / SecondNoun étant en gras.
