「Recent Trade Price:~」の後の数字を取得したいのですが、数字は 1 ～ 7 桁の範囲で変化するため、すべての数字で機能する必要があります。文字列を正しく解析する方法がわからないので、「最近の取引価格」の後に数字だけを取得します

私は使用してみました：

$text = $html->plaintext;
$words = explode("Recent Trade Price:", $text);
echo $words[1];

しかし、これですべてが得られたので、途中までだと思います。誰か助けてください！

これは、このテキストがどの程度厳格で構造化されているかによって異なります。数字の前に常にスペースと「~」がありますか?

ここでは、おそらく正規表現が最も役立ちます。 preg_matchこれであなたを助けます。

http://php.net/manual/en/function.preg-match.php

preg_match('/Recent Trade Price: ~(\d+)/', $text, $matches);
print_r($matches);

印刷します：

Array ( [0] => Recent Trade Price: ~55 [1] => 55 )

編集

あなたのコメントによると、取得しようとしている数字にコンマが含まれている場合は、最初のスペースまでのすべての文字を取得する別の正規表現を使用できます

preg_match('/Recent Trade Price: ~(\S+)/', $text, $matches);
print_r($matches);

印刷します：

Array ( [0] => Recent Trade Price: ~555,000 [1] => 555,000 )

そこから、必要に応じてカンマを取り除くことができます。繰り返しますが、これはテキスト形式がどれだけ厳格で予測可能かによって異なります...
