我必須檢查一組字符串數(shù)據(jù)。例如，這是字符串：$keywords="today, tomorroy, world, is a good day , a good day is, today"我必須檢查是單詞還是多詞。如果是多個單詞，我必須訂購并只留下一個，例如：是美好的一天；美好的一天是我必須離開的唯一：是美好的一天。這句話我必須存儲在其他數(shù)組中。最后我必須只有這個結果：這是我的代碼： $keywords = ""; $singleword=""; $multiword=""; foreach ($response->getResults() as $result) { $keywords .= $result->getText()->getValue() . ","; if(count(explode(' ', $keywords)) > 1) { $multiword++; } $singleword++; } return $keywordsgenerated;我需要返回：今天，明天，世界，是美好的一天請你幫我解決，我是 php 的新手。

我想你正在尋找這樣的東西：
<?php
$keywords="today, tomorrow, world, is a good day , a good day is, today";
$arr = array_unique(explode(",",$keywords));
$words = [];
foreach($arr as $key=>$a) {
$words_explode = explode(" ", $a);
foreach($words_explode as $w) {
$words[] = $w;
}
}
$new_words = array_unique($words);
$result = implode(" ", $new_words);
foreach($arr as $item) {
$result = str_replace($item,$item.",",$result);
}
$result = trim($result,", ");
var_dump($result);
更新：
我認為？我得到你要找的東西了嗎？
$keywords = "hansgrohe,hansgrohe focus,küchenarmatur,hansgrohe metris";
$arr = explode(',', $keywords);
$already = [];
$result = '';
foreach($arr as $word) {
$subword = explode(" ", $word);
foreach($subword as $actual_word) {
if (!in_array($actual_word, $already)) {
$result .= $actual_word . ' ';
$already[] = $actual_word;
}
}
}
$result = rtrim($result);
//would result in hansgrohe focus küchenarmatur metris
echo $result;
更新2：
如果你想知道每個單詞出現(xiàn)的次數(shù)。
<?php
$keywords = "hansgrohe,hansgrohe focus,küchenarmatur,hansgrohe metris";
$arr = explode(",", $keywords);
$already = [];
$nrwords = [];
$result = '';
foreach($arr as $word) {
$subword = explode(" ", $word);
foreach($subword as $actual_word) {
if (!in_array($actual_word, $already)) {
$result .= $actual_word . ' ';
$already[] = $actual_word;
$nrwords[$actual_word] = 0;
}
$nrwords[$actual_word]++;
}
}
$result = rtrim($result);
//would result in hansgrohe focus küchenarmatur metris
echo $result;
//would show how many of each word that exists
echo '<pre>';
print_r($nrwords);
echo '</pre>';
