字符串分析帮助

我很快就写下了:

<?php
$text = <<<EOT
####################
Section One
####################
Data B.Thing=bar#
.##.#%#

####################
   Empty Section!
####################
####################
   Last section
####################

Blah

   Blah C# C# C#

EOT;
$entries = array_chunk(
   preg_split("/^#+/m", $text, null, PREG_SPLIT_NO_EMPTY),
   2
);
$sections = array();
foreach ($entries as $entry) {
  $key = trim($entry[0]);
  $value = preg_split("/\n/", $entry[1], null, PREG_SPLIT_NO_EMPTY);
  $sections[$key] = $value;
} 
print_r($sections);
?>

输出为:( as run on ideone.com )

Array
(
    [Section One] => Array
        (
            [0] => Data B.Thing=bar#
            [1] => .##.#%#
        )

    [Empty Section!] => Array
        (
        )

    [Last section] => Array
        (
            [0] => Blah
            [1] =>    Blah C# C# C#
        )

)

我会采取多步骤的方法:

• 分成章节标题/内容
• 将每个标题/内容对解析为所需的数组结构

下面是一个例子,分成多行,这样您就可以跟踪正在发生的事情:

^{注意缺乏健全的检查,这是 假设 标题/内容组漂亮、整洁。
regex是为简洁而编写的,可能不足以满足您的需要。}

// Split string on a line of text wrapped in lines of only #'s
$parts = preg_split('/^#+$\R(.+)\R^#+$/m', $subject, null, PREG_SPLIT_DELIM_CAPTURE|PREG_SPLIT_NO_EMPTY);
// Tidy up leading/trailing whitespace for each heading/content-block
$parts = array_map('trim', $parts);
// Chunk into array("heading", "content")
$parts = array_chunk($parts, 2);

// Create the final array
$sections = array();
foreach ($parts as $part) {
    $sections[$part[0]] = explode("\n", $part[1]);
}

// Lets take a look
var_dump($sections);
