Question

如果我有阵列：

$os = array("Mac", "NT", "Irix", "Linux");

我知道如果我想在in_array()内找到"Mac"，$os即可使用。

但我有阵列：

$os = array( [1] => "Mac/OSX", [2] => "PC/Windows" );

我想知道"Mac"中是否包含$os？

Answer 1

尝试：

$example = array("Mac/OSX","PC/Windows" );
$searchword = 'Mac';
$matches = array_filter($example, function($var) use ($searchword) { return preg_match("/\b$searchword\b/i", $var); });

Answer 2

你可以尝试这个 -

$os = array( "Mac/OSX", "PC/Windows" );    
function findInArray($os){
 foreach($os as $val){
  if(strpos($val, $word_to_search) !== false){
   return true;
  }
 }
 return false;
}

Answer 3

您也可以使用array_map来执行此操作。看看下面的代码：

$array = array(
    'Mac/OSX',
    'PC/Windows',
);



$result = in_array(true, array_map(function ($word, $match, $char = "/") {
    $words = explode('/', $word);
    return in_array($match, $words) ? true : false;
}, $array, array('Mac')));

var_dump($result); // bool(true)

Answer 4

这是另一种解决方案：

public class CustomListView extends ListView{

   @Override
   protected void dispatchDraw(Canvas canvas) {
      try {
          super.dispatchDraw(canvas);
      } catch (IndexOutOfBoundsException e) {
          Log.e("luna", "Ignore list view error ->" + e.toString());
      }
   }
}

Answer 5

你可以简单地使用PHP的preg_grep功能，如

$os = array( '1' => "Mac/OSX", '2' => "PC/Windows" );

print_R(preg_grep("/Mac/",$os));

输出：

Array ( [1] => Mac/OSX )

Answer 6

使用foreach和strpos

$os =array("Mac/OSX","PC/Windows" );
$string = "Mac";
foreach ($os as $data) {
   //echo $data;
    if (strpos($data,$string ) !== FALSE) { 
        echo "Match found"; 
    }else{
        echo "not found";
    }
}

 function FindString($string, $os)
 {
    // put the string in between // 
    $preg = "/$string/";

    // Match found 
    $found = false;

    // loop each value 
    for($j = 0; $j < count($os); $j++)
    {
        // check with pattern 
        if(preg_match($preg,$os[$j]))
        {
            // set var to ture 
            $found = true;

            // Break 
            break;
        }
    }

    if($found == false)
    {
        die("Unable to found the string $string.");
    }

    echo "String $string found in array index $j and value is $os[$j]";

 }

 $where =array("Mac/OSX","PC/Windows" );
 $what = "Mac";
 FindString($what, $where);
