preg_match_all奇妙なこと

Question

[quote][/quote]で囲まれたテキストがあります。これらのタグの前にあるすべてのテキスト、これらのタグの間のすべて、およびこれらのタグの後ろのすべてを照合しようとしています。キャッチとは、それらが複数存在する可能性があるが、互いに存在しないことである。

私がこれを行うのは、複数の出現の有無にかかわらず、それらのタグの外のすべてのテキストに対してフィルタを実行したいからです。

これは、私が一緒に仕事し始めているものです：

preg_match_all("/(^.*)\[quote\](.*?)\[\/quote\](.*)/si", $reply['msg'], $getthequotes); 

ここでは出力です：

Array 
(
[0] => Array 
    (
     [0] => putting some stuff before the quote

あなたはそれが所望の出力を得ていない見ることができるように。どんな助けもありがとう。

Answer 1

私はこれを試していないが、しかし、あなたは唯一の[quote]前のものにしたいと[/quote]後、あなたはオープニング引用タグの最初の出現のためにstrposを行うことができます。今では、前にすべてが引用されていないことを知っています。

次に、最初に一致する見積もりタグのインデックスから始まるstrposを使用して、終了見積もりタグを見つけることができます。あなたはこのものを捨てることができます。

今すぐ見つけた閉じ引用タグの開始位置を使用して、次の引用ブロックの別のstrposを実行します。あなたは終わりまでこれを繰り返すことができます。

Answer 2

これは可能ですが、文字列に複数のパスを設定する必要があります。

$string = 'putting some stuff before the quote

adding a quote'; 

//get rid of whitespace 
$string = preg_replace('%\s\s?%', " ",$string); 
//break the string on a common element 
$pieces = preg_split('%\[%',$string); 
//now discard the elements that are tags 
foreach($pieces as $key=>$value): 
    $value = trim($value); 
    if(strrpos($value,"]") == (strlen($value) -1)): 
     unset($pieces[$key]); 
    endif; 
endforeach; 
print_r($pieces); 
//and finally strip out the tag fragments 
foreach($pieces as $key=>$value): 
    $pieces[$key] = preg_replace('%.*]%',"",$value); 
endforeach; 

結果は次のようになり、配列：
