循环遍历数组，并检查其中一个值是否为字符串

Question

我有

字符串 $input =“John的一加二”，

数组 $devices

我想要

循环遍历我的数组，并检查我的$input子字符串是否包含我的$devices数组的设备名称之一。

我试过

foreach ($devices as $i=>$device) {
    if( stripos($input, $device['name']) !== false){
        dd('True');
    }
    else
        dd('False');

}

我得到了

False打印。尽管如此，我知道one-plus-2实际上存在于我的设备阵列中。

11 => array:1 ["name" => "one-plus-2"]

我错过了什么吗？

对此的任何提示/建议将不胜感激！

Answer 1

您可以将array_filter()与strpos()：

一起使用

$matches = array_filter($devices, function($device) use ($input) {
  return strpos($input, $device['name']) !== FALSE;
});
dd($matches);

array_filter()没有重新编制索引，因此第一个键不是0，而是11（在这种情况下）。

Answer 2

stripos＆gt;＆gt;＆gt; strpos

“stripos”错误，正确的是“strpos”

且参数必须为

strpos（要搜索的字符串，您想要的字符串）

if (strpos($device['name'], $input) !== false) {
    echo 'true';
}

Answer 3

您已切换针和干草堆参数
试试这个

if( stripos($device['name'], $input) !== false){ ...}
