問(wèn)題描述有三個(gè)數(shù)組，如下：// 數(shù)字?jǐn)?shù)組$numbers = ['17', '38', '12', '40', '20', '47', '45', '22', '02', '19', '29', '10', '27', '41', '26', '47', '18', '24', '22', '27', '33', '47', '25', '09', '16', '32', '01', '28', '18', '38'];// 單雙數(shù)組$oddEven = ['1', '2', '2', '2', '2', '1', '1', '2', '2', '1', '1', '2', '1', '1', '2', '1', '2', '2', '2', '1', '1', '1', '1', '1', '2', '2', '1', '2', '2', '2'];// 匹配數(shù)組$matchArr = ['1', '2', '2', '2'];現(xiàn)在我想用$matchArr匹配$oddEven，請(qǐng)問(wèn)下怎么才能把$oddEven中的3個(gè)['1', '2', '2', '2']給匹配出來(lái)？同時(shí)能對(duì)應(yīng)上$numbers中的數(shù)字？我希望的結(jié)果是：$result[0] = ['17', '38', '12', '40'];
$result[1] = ['47', '18', '24', '22'];
$result[2] = ['01', '28', '18', '38'];或者合并在一起也可以，可以有重復(fù)的值：$result = ['17', '38', '12', '40', '47', '18', '24', '22', '01', '28', '18', '38'];我試過(guò)把數(shù)組轉(zhuǎn)成字符串使用preg_match_all()進(jìn)行匹配，但是這樣就無(wú)法與$numbers對(duì)應(yīng)了。實(shí)在想不到什么辦法了，請(qǐng)大家?guī)蛶臀?，謝謝了。

思路：
確認(rèn)matchArr在oddEven的位置，比如1,10,20
根據(jù)上面獲取的位置，取出number里的數(shù)據(jù)，最后拼接
實(shí)現(xiàn)：
$numbers = ['17', '38', '12', '40', '20', '47', '45', '22', '02', '19', '29', '10', '27', '41', '26', '47', '18', '24', '22', '27', '33', '47', '25', '09', '16', '32', '01', '28', '18', '38'];// 單雙數(shù)組$oddEven = ['1', '2', '2', '2', '2', '1', '1', '2', '2', '1', '1', '2', '1', '1', '2', '1', '2', '2', '2', '1', '1', '1', '1', '1', '2', '2', '1', '2', '2', '2'];
$oddEvenStrs = implode("", $oddEven);// 匹配數(shù)組$matchArr = ['1', '2', '2', '2'];
$matchArrStrs = implode("", $matchArr);
var_dump($oddEvenStrs);
var_dump($matchArrStrs);
var_dump(count($numbers));function findIt($from, $find, $numbers, $pos) {
$result = '';
$pos = strpos($from, $find, $pos); if ($pos !== false) {
$result .= implode(",", array_slice($numbers, $pos, 4));
$pos += 4;
}
if (count($numbers) > $pos)
{ return $result . "," . findIt($from, $find, $numbers, $pos);
}
return $result;
}
$result = findIt($oddEvenStrs, $matchArrStrs, $numbers, 0);echo $result;
var_dump(explode(",", $result));- 1 回答
