问题/问题
有一个database of bot information我想解析。据说是similar to RFC822 messages .
在我重新发明轮子并编写自己的解析器之前,我想我会看看是否还有其他可用的东西。我偶然发现 imap_rfc822_parse_headers()
,这似乎正是我想要的。不幸的是,IMAP 扩展在我的环境中不可用。
我在网上和 Stack Overflow 上看到了很多替代方案。不幸的是,它们都是为电子邮件而构建的,并且做的比我需要的更多……经常解析整个电子邮件并以特殊方式处理标题。我只想简单地将这些 header 解析为一个有用的对象或数组。
是否有 imap_rfc822_parse_headers()
的直接 PHP 版本可用的,或者类似的东西可以解析这样的数据?如果没有,我会自己写。
样本数据
robot-id: abcdatos
robot-name: ABCdatos BotLink
robot-from: no
robot-useragent: ABCdatos BotLink/1.0.2 (test links)
robot-language: basic
robot-description: This robot is used to verify availability of the ABCdatos

temporary situation.

working in the directory maintenance.

最佳答案
假设 $data
包含您在上面粘贴的示例数据,这里是解析器:
<?php
/*
* $data = <<<'DATA'
* <put-sample-data-here>
* DATA;
*
*/
$parsed = array();
$blocks = preg_split('/\n\n/', $data);
$lines = array();
$matches = array();
foreach ($blocks as $i => $block) {
$parsed[$i] = array();
$lines = preg_split('/\n(([\w.-]+)\: *((.*\n\s+.+)+|(.*(?:\n))|(.*))?)/',
$block, -1, PREG_SPLIT_DELIM_CAPTURE);
foreach ($lines as $line) {
if(preg_match('/^\n?([\w.-]+)\: *((.*\n\s+.+)+|(.*(?:\n))|(.*))?$/',
$line, $matches)) {
$parsed[$i][$matches[1]] = preg_replace('/\n +/', ' ',
trim($matches[2]));
}
}
}
print_r($parsed);
关于php - 解析类似电子邮件的 header (类似于 RFC822),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/12804880/
