Строка до 3-х массивов с PHP

Question

Привет, ребята, у меня есть блок текста, который я хочу разделить на три части, но я заметил, что нет ничего общего с этими частями, которые я мог бы использовать как разделитель для функции explode ().

Есть ли способ, которым я могу разделить это, 3 блока нужно знать: что и почему и кстати?

РЕДАКТИРОВАТЬ:

$description = preg_split('/Need to know:| What & why:|By the way:/i', $product['text']['desc'], 3);

Ладно, кстати, есть бит в массиве, но биты «нужно знать» и «что и почему» находятся в одном массиве, может кто-нибудь помочь с этим? :)

Answer 2

РЕДАКТИРОВАТЬ: Не обращайте внимания. Я неправильно прочитал пост. Оставляя контент, потому что он работает для произвольных строк.

Лично я бы разделил пробел. Возможно, есть и лучшие места, но не обошлось без особой специфики приложения.

Вот быстрый грязный подход (с использованием функции wordwrap ):

// Number of desired chunks
$chunks = 3;
$data = "LONG CHUNK OF TEXT HERE";

// Prep the data by removing newlines.
$data = str_replace("\n", '', $data);

// Use the built in wordwrap function to split to size
$data = wordwrap($data, ceil(strlen($data) / $chunks));

// Split on the newly inserted newlines
$parts = explode("\n", $data);

// $parts is now an array with $chunks number of parts, all about the same length.

Answer 3

Не так элегантно, как регулярные выражения, но:

$start2 = strpos($description, "What & why:");
$start3 = strpos($description, "By the way:"); 
$part1 = substr($description, 0, $start2);
$part2 = substr($description, $start2, $start3 - $start2);
$part3 = substr($description, $start3);

Редактировать: Сделайте это, чтобы исключить текст "Что и почему / Кстати":

$start2 = strpos($description, "What & why:") + strlen("What & why:");
$start3 = strpos($description, "By the way:") + strlen("By the way:");
$end1 = $start2 - strlen("What & why:");
$end2 = $start3 - strlen("By the way:") - $start2;

$part1 = substr($description, 0, $end1);
$part2 = substr($description, $start2, $end2);
$part3 = substr($description, $start3);

Просто разбить его по подстроке:

$d_length = strlen($description);
$part = (int) ($d_length / 3);

$p1 = substr($description, 0, $part);
$p2 = substr($description, $part, $part);
$p3 = substr($description, ($part*2));

echo $p1.PHP_EOL;
echo $p2.PHP_EOL;
echo $p3.PHP_EOL;

Если есть определенная длина, которую может содержать каждая часть, вы можете разделить их, используя функцию php strpos ().В противном случае вы можете проверить точку и капитал после каждой части?Надеюсь, это поможет.
