在特定符号PHP之前获取字符串

Question

假设我有String as

$b = 'grapes, pineapple & fruit seller offered by flipkart from usa';

从这个字符串我想要3个单词如下

1. 葡萄
2. 菠萝
3. 水果卖家

我通过explode（）获得的第一个单词

我得到的第三个字代码

$bb = explode(",",$b);
$demo1 = substr($bb[1], strpos($bb[1], "&") + 1)."<br>";
$demo2 = str_replace($demo1, "", $bb[1])."<br>";
$result = substr($demo2, strpos($demo2, "&") + 1);
$newres = explode(" ",$result);
foreach($newres as $value){
    if($value == "offered"){
        break;
    }
    $myarr[] = $value;
}
$thirdkeyword = implode(" ",$myarr);
echo "Third Keyword :".$thirdkeyword."<br>";

返回给我fruit seller。

但现在我想要第二个字菠萝。那么我怎样才能在＆amp;（AND）之前得到这个词。

Answer 1

$b = 'grapes, pineapple & fruit seller offered by flipkart from usa';

$str = explode(' offered', $b)[0];
$result = preg_split('/\s*[,&]\s*/', $str);

print_r($result); 

结果

Array
(
    [0] => grapes
    [1] => pineapple
    [2] => fruit seller
)
