Question

这个问题是我上一个问题的延续：

Check tag & get the value inside tag using PHP

我有这样的文字：

<ORGANIZATION>Head of Pekalongan Regency</ORGANIZATION>, Dra. Hj.. Siti Qomariyah , MA and her staff were greeted by <ORGANIZATION>Rector of IPB</ORGANIZATION> Prof. Dr. Ir. H. Herry Suhardiyanto , M.Sc. and <ORGANIZATION>officials of IPB</ORGANIZATION> in the guest room.

使用之前我的问题的答案代码和PREG_OFFSET_CAPTURE添加如下：

function get_text_between_tags($string, $tagname) {
    $pattern = "/<$tagname\b[^>]*>(.*?)<\/$tagname>/is";
    preg_match_all($pattern, $string, $matches, PREG_OFFSET_CAPTURE);
    if(!empty($matches[1]))
        return $matches[1];
    return array();
}

我得到一个输出：

阵列（
  [0] =＆gt;数组（[0] =＆gt; Pekalongan Regency头[1] =＆gt; 14）
  [1] =＆gt;数组（[0] =＆gt; IPB [1] => 131的校长）
  [2] =＆gt;数组（[0] =＆gt;官方IPB [1] =＆gt; 222））

14,11,222是匹配模式时的字符索引。我可以获得单词索引吗？我的意思是这样的输出：

阵列（
  [0] =＆gt;数组（[0] =＆gt; Pekalongan Regency头[1] =＆gt; 0）
  [1] =＆gt;数组（[0] =＆gt; IPB [1]的校长=＆gt; 15）
  [2] =＆gt;数组（[0] =＆gt;官方IPB [1] =＆gt; 27））

除了PREG_OFFSET_CAPTURE还是需要更多代码之外还有其他方法吗？我不知道。感谢帮助。：）

Answer 1

这会有效，但需要一点点完成：

<?php

$raw = '<ORGANIZATION>Head of Pekalongan Regency</ORGANIZATION>, Dra. Hj.. Siti Qomariyah , MA and her staff were greeted by <ORGANIZATION>Rector of IPB</ORGANIZATION> Prof. Dr. Ir. H. Herry Suhardiyanto , M.Sc. and <ORGANIZATION>officials of IPB</ORGANIZATION> in the guest room.';

$result = getExploded($raw,'<ORGANIZATION>','</ORGANIZATION>');

echo '<pre>';
print_r($result);
echo '</pre>';

function getExploded($data, $tagStart, $tagEnd) {
    $tmpData = explode($tagStart,$data);
    $wordCount = 0;
    foreach($tmpData as $k => $v) {
        $tmp = explode($tagEnd,$v);
        $result[$k][0] = $tmp[0];
        $result[$k][1] = $wordCount;
        $wordCount = $wordCount + (count(explode(' ',$v)) - 1);
    }
    return $result;
}

＆GT;

结果是：

Array
(
    [0] => Array
        (
            [0] => 
            [1] => 0
        )

    [1] => Array
        (
            [0] => Head of Pekalongan Regency
            [1] => 0
        )

    [2] => Array
        (
            [0] => Rector of IPB
            [1] => 16
        )

    [3] => Array
        (
            [0] => officials of IPB
            [1] => 28
        )

    )

使用PHP从文本中获取索引
