如何在数组中使用Preg Match？ [英] How to use preg match in array?

问题描述

如果我有一个数组：

Array
(
    [0] => Array
        (
            [0] => |174|September|2001| 
            [1] => |Pengantar=Hello!!!!
            [2] => |Tema= Sami Mawon 
            [3] => |Tema_isi=meet you!!!
            [4] => |Kutip=people
            [5] => |Kutip_kitab=Efesus
            [6] => |Kutip_pasal=4
            [7] => |Kutip_ayat=28
            [8] => |Tema_sumber=Kiriman dari Maurits albert (romind@ )
            [9] => [[Kategori:e-humor 2001]]
        ) 

如何获取Pengantar，Tema，Tema_isi等的值？

How can I get the value of Pengantar, Tema, Tema_isi etc?

推荐答案

正则表达式可以像这样，使用命名子模式 http://php.net/manual/zh-CN/function.preg-match.php rel = nofollow> preg_m atch（） ：-

The regular expression can be like this, using the named subpattern of "preg_match()":-

$a = array(
    array(
        '|174|September|2001|',
        '|Pengantar=Hello!!!!',
        '|Tema= Sami Mawon',
        '|Tema_isi=meet you!!!',
        '|Kutip=people',
        '|Kutip_kitab=Efesus',
        '|Kutip_pasal=4',
        '|Kutip_ayat=28',
        '|Tema_sumber=Kiriman dari Maurits albert (romind@ )',
        '[[Kategori:e-humor 2001]]',
    )
);
$pattern = '/(?<first>\w+)[:=](?<rest>[\d|\w|\s]+)/';
$matches = array();
foreach ($a as $_arrEach) {
    foreach ($_arrEach as $_each) {
        $result = preg_match($pattern, $_each, $matches[]);
    }
}

echo "<pre>";
print_r($matches);
echo "</pre>";

您会发现数组键 first 满足您的要求。

You will find that the array key "first" satisfies your requirement.

上面的内容将输出为：-

The above will output as:-

Array
(
    [0] => Array
        (
        )

    [1] => Array
        (
            [0] => Pengantar=Hello

)
