我想找到“KSE100KSE30KMI30”，它位于键号23。我已经尝试过in_array和包括preg_match在内的其他php数组函数，但在数组中找不到字符串。有没有办法在我的数组中找到字符串。如果是，那就告诉我

Answer 1

您的"kse 100 kse 30 kmi 30“在数组中的字符串前后有一个空格”“。

string(136) " kse 100 kse 30 kmi 30 "

这就是你找不到它的原因吗？因为array_serach、in_array和其他函数都在寻找精确值。

否则，使用strstr来比较您的字符串是否在您的草堆中，但要小心。如果您的数组中有类似的内容，如"Hello“和"Hello World”，您可能会发现错误的条目，这并不是一个很好的唯一解决方案。

无论如何，我留下一个简单的例子：

$found = false;
foreach($myArray as $key => $value) {
    if(strstr($value, "kse 100 kse 30 kmi 30") == true) {
        $found = true;
        break;
    }
}
if($found == true) {
    //Do something awesome!
} else {
    //Do something not so awesome but still cool?
}

Answer 2

谢谢你的帮助，但我自己解决

for ($index = 10; $index < 35; $index++) {
    if (substr_count(array[$index], 'kse 100') > 0) {
      $IndexKey = $index;
    }     
}

获取该变量所在位置的key的值。

Answer 3

对于第一个匹配的：

$key = key(preg_grep('/kse 100/', $array));
