在php中搜索数组中的子字符串

发布于 2024-12-15 00:53:09 字数 481 浏览 0 评论 0原文

我正在尝试搜索字符串中某些单词的出现并将它们与数组中的短列表进行匹配。我将通过一个例子来解释我的问题。

            $arrTitle = explode(" ", "Suburban Apartments");
    foreach( $arrTitle as $key => $value){
        echo "Name: $key, Age: $value <br />";
        $words = array("hotel", "apart", "hostel");
        if (in_array($value, $words)) {
            echo "Exists";
        }
    }

我希望将上面示例中的字符串的一部分“Apartments”与 $words 数组进行比较，以查找字符串“Apart”的出现情况。我希望这是有道理的。这有可能吗？

谢谢

I'm trying to search for the occurrence of certain words in a string and match them with a short list in an array. I'll explain my question by means of an example.

            $arrTitle = explode(" ", "Suburban Apartments");
    foreach( $arrTitle as $key => $value){
        echo "Name: $key, Age: $value <br />";
        $words = array("hotel", "apart", "hostel");
        if (in_array($value, $words)) {
            echo "Exists";
        }
    }

I wish to compare a part of the string, in the above example 'Apartments' against the $words array for the occurrence of the string 'Apart'ments.
I hope this makes sense. Is this possible at all?

Thanks

然后你必须稍微改变一下你的代码。请看下面的内容：

$arrTitle = explode(" ", "Suburban Apartments");
foreach( $arrTitle as $key => $value){
    echo "Name: $key, Age: $value <br />";
    $words = array("hotel", "apart", "hostel");
    foreach($words as $word){
        if (stripos($value, $word) !== false) {
            echo "Exists";
        }
    }
}

注意要搜索的单词上添加的 foreach 以及 strpos 的 in_array 替换。

对于您的个人信息，in_array 检查 $word 是否作为整个值存在于数组中，这不是您想要的。您需要使用 strpos 或 stripos （不区分大小写）检查每个单词是否存在...

Then you'll have to change a bit your code. Look at this below:

$arrTitle = explode(" ", "Suburban Apartments");
foreach( $arrTitle as $key => $value){
    echo "Name: $key, Age: $value <br />";
    $words = array("hotel", "apart", "hostel");
    foreach($words as $word){
        if (stripos($value, $word) !== false) {
            echo "Exists";
        }
    }
}

Note the added foreach on the words to search and the in_array replacement for strpos.

For your personnal information, in_array checks if the $word is in the array as a whole value, which is not what you wanted. You need to check for the existence of each word using strpos or stripos (case insensitive)...
