Diviser les phrases en paragraphes en fonction du nombre de mots comptés

Question

Je souhaite diviser une phrase en un paragraphe et chaque paragraphe doit contenir moins de nombres de mots. Par exemple:

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. 

Paragraph 1: 
Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. 

Paragraph 2: 
Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. 

Dans l'exemple ci-dessus, les mots moins de 20 est dans un paragraphe 1 et le repos sont sur le paragraphe 2.

Est-il possible d'y parvenir en utilisant php?

J'ai essayé $abc = explode(' ', $str, 20); qui va stocker 20 mots dans un tableau puis le reste d'entre eux pour le tableau $ abc ['21 ']. Comment puis-je extraire des données du premier tableau 20 comme le premier paragraphe, puis le reste comme le deuxième paragraphe?

Answer 1

Première chaîne divisée en phrases. Puis bouclez le tableau des phrases, commencez par ajouter la phrase à un tableau de paragraphes, puis comptez les mots dans cet élément du tableau de paragraphes, si le compteur de paragraphes est supérieur à 19.

$string = 'Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.'; 

$sentences = preg_split('/(?<=[.?!;])\s+(?=\p{Lu})/', $string); 

$ii = 0; 
$paragraphs = array(); 
foreach ($sentences as $value) { 
    if (isset($paragraphs[$ii])) { $paragraphs[$ii] .= $value; } 
    else { $paragraphs[$ii] = $value; } 
    if (19 < str_word_count($paragraphs[$ii])) { 
     $ii++; 
    } 
} 
print_r($paragraphs); 

Sortie:

Array 
(
    [0] => Contrary to popular belief, Lorem Ipsum is not simply random text.It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. 
    [1] => Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. 
)
