字符串到3阵列与PHP

Question

嗨伙计我有一块文本，我想分成三部分，但我注意到这些部分没有什么共同点，我可以用作explode（）函数的分隔符。

有没有什么办法可以分割这3块需要知道：什么，为什么，顺便说一句？

编辑：

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

好得到了，顺便位阵列，但“需要知道”和“什么&为什么”位在同一阵列门槛，任何人都可以在这方面帮助？ :)

如果每个部分都有一定的长度，可以使用php strpos（）函数将它们分开。否则，您可以在每个部分之后检查点和​​资本？希望这可以帮助。

由子只是把它分解：

编辑：忽略此。我误读了帖子。因为它适用于任意字符串，所以将内容保留起来。

就我个人而言，我会分割空白。可能有更好的地方，但不是没有关于应用程序的更多细节。

这里有一个快速的肮脏的方法（使用wordwrap功能）：

// 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.

还不如优雅的正则表达式，但：

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

编辑：这样做是为了排除什么&为什么/顺便说一句：

$start2 = strpos($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);
