$a='现在已经是夏天了';
$b=array("保存",""加入","夏天");

怎么查询字符串$a是否包含数组$b中某个值,并且返回数组$b键名。

回复内容:

$a='现在已经是夏天了';
$b=array("保存",""加入","夏天");

怎么查询字符串$a是否包含数组$b中某个值,并且返回数组$b键名。

没想到批量查找的方法

<code>$match_keys =array();
foreach($b as $key=>$findme){
    if(strpos($a,$findme) !==false){
        $match_keys[]=$key;
    }
}
$match_keys = array_unique($match_keys);</code>
