PHP Match alle Zeichen in der neuen Zeile mit Regex

Question

Ich möchte jedes Zeichen nachBBCode übereinstimmen, aber der unten BBCode stimmt nicht überein Texte, die folgen, wenn ich eine Bruchlinie mache.

$string="[nextpage] This is how i decided to make a living with my laptop. 
This doesn't prevent me from doing some chores, 

I get many people who visits me on a daily basis. 

[nextpage] This is the second method which i think should be considered before taking any steps. 

That way does not stop your from excelling. I rest my case."; 

$pattern="/\[nextpage\]([^\r\n]*)(\n|\r\n?|$)/is"; 
preg_match_all($pattern,$string,$matches); 
$totalpages=count($matches[0]); 
$string = preg_replace_callback("$pattern", function ($submatch) use($totalpages) { 
$textonthispage=$submatch[1]; 
return "<li> $textonthispage"; 
}, $string); 
echo $string; 

Dies gibt nur die Texte in der ersten Zeile zurück.

<li> This is how i decided to make a living with my laptop. 

<li> This is the second method which i think should be considered before taking any steps. 

Erwartetes Ergebnis;

<li> This is how i decided to make a living with my laptop. 
This doesn't prevent me from doing some chores, 

I get many people who visits me on a daily basis. 

<li> This is the second method which i think should be considered before taking any steps.

können Sie suchen diese regex:

\[nextpage]\h*(?s)(.+?)(?=\[nextpage]|\z) 

ersetzen durch:

<li>$1

RegEx Breakup:

\[nextpage]   # match literal text "[nextpage]" 
\h*     # match 0+ horizontal whitespaces 
(?s)(.+?)   # match 1+ any characters including newlines 
(?=\[nextpage]|\z) # lookahead to assert that we have another "[nextpage]" or end of text 

Answer 2

Wenn Sie eine feste Zeichenfolge Sie sollten nicht regex. Regex ist teuer, eine einfache str_replace funktioniert den Trick auch:

$result = str_replace("[nextpage]", "<li>", $str); 

---

Wenn Sie es als richtiger HTML, Sie auch einen engen andneedtag:

$result = str_replace("[nextpage]", "</li><li>", $string); 
$result = substr($result, 5, strlen($result)).'</li>'; // remove the start </li> 

echo $result;
