Humphrey DeForest Bogart (December 25, 1899 – January 14, 1957) was an American actor. He is widely regarded as a cultural icon. The American Film Institute ranked Bogart as the greatest male star in the history of American cinema.

After trying various jobs, Bogart began acting in 1921 and became a regular in Broadway productions in the 1920s and 1930s. When the stock market crash of 1929 reduced the demand for plays, Bogart turned to film. His first great success was as Duke Mantee in The Petrified Forest (1936), and this led to a period of typecasting as a gangster with films such as Angels with Dirty Faces (1938) and B-movies like The Return of Doctor X (1939).

His breakthrough as a leading man came in 1941, with High Sierra and The Maltese Falcon. The next year, his performance in Casablanca raised him to the peak of his profession and, at the same time, cemented his trademark film persona, that of the hard-boiled cynic who ultimately shows his noble side. Other successes followed, including To Have and Have Not (1944), The Big Sleep (1946), Dark Passage (1947) and Key Largo (1948), with his wife Lauren Bacall; The Treasure of the Sierra Madre (1948); The African Queen (1951), for which he won his only Academy Award; Sabrina (1954) and The Caine Mutiny (1954). His last movie was The Harder They Fall (1956). During a film career of almost thirty years, he appeared in 75 feature films.

$start_sec = strpos($para, "\n");  // get start position of 2nd paragraph
$start_end = strrpos($para, "\n"); // get start position of last paragraph

$new_para = trim(substr($para, $start_sec, $start_end - $start_sec)); // get substring of content until start of last paragraph
$last_para = trim(substr($para, $start_end)); // get substring of content from start of last paragraph until end

echo $new_para;  // output all paragraphs but first and last
echo $last_para; // output last paragraph

さらに説明が必要な場合は、さらに説明できますが、非常に簡単です。最初と最後の段落なしでコンテンツを出力し、最後の段落を個別に出力することもできます。

提供された画像からわかるように (次回は実際のコードを提供してください!)、文字列は二重の改行で区切られています。その場合、次のことができます。

$result_array = explode("\n\n", $string);

これにより、各段落の配列が得られます。

属性をそのままにしておくことを検討してください。<small>および<footer>HTML タグを使用して、そのように指定します。
