Question

我想将一个字符串拆分为2个变量，但是给一个变量约75％的字符串，另一个变量25％。

我有这个代码，它将数据库中的一个段落分成2个，但是现在我需要给出一个部分2/3的单词而另一个部分给出1/3的单词。这甚至是可能的：

这是我目前的代码：

$pagetext = mysql_result($result, $i, "column");
$thewordamt = str_word_count($pagetext);
$halfwords = $thewordamt / 2;

function limit_words($string, $word_limit) {
    $words = explode(" ", $string);
    return implode(" ", array_splice($words, 0, $word_limit));
}

$start = limit_words($pagetext, $halfwords); //first part
$end = str_replace($start, '', $pagetext); //second part

Answer 1

我认为这解释了自己：

$txt = "I met him on a Monday and my heart stood still
Da do ron-ron-ron, da do ron-ron
Somebody told me that his name was Bill
Da do ron-ron-ron, da do ron-ron";

$parts = daDoRunRun($txt, 0.33);

printf('<p>%s</p><p>%s</p>', $parts['short'], $parts['long']);


function daDoRunRun($txt, $short_part_percentage) {
    $split_index = floor(str_word_count($txt)*$short_part_percentage);
    $words = explode(' ', $txt);

    return [
        'short' => join(' ', array_splice($words, 0, $split_index)),
        'long' => join(' ', $words)
    ];
}

拆分2个变量中的字符串，但给出一个变量2/3的单词
