PHP返回關聯數組，通過多元素搜​​索？

Question

我有一個數組，看起來是這樣的：

$array = array(
    array('Field1' => 'red', 'Field2' => 'green', 'Field3' => 'blue'), 
    array('Field1' => 'pink', 'Field2' => 'pinkish', 'Field3' => 'barbiecolor'), 
    array('Field1' => 'red', 'Field2' => 'blue', ' Field3' => 'orange') 
); 

而且我想通過給定的值進行檢查：

$searchBy = array('Field1' => 'red', 'Field2' => 'blue'); 

我想達到的目標是要回歸父數組具有匹配的所有關聯密鑰&值對。我試過in_array()，但它不工作..

Answer 1

array_filter可能是這更好：

$matches = array_filter($array,function($a) use ($searchBy) { 
    foreach($searchBy as $k=>$v) { 
     if($a[$k] != $v) return false; 
    } 
    return true; 
}); 

Answer 2

你可以試試：

$find = array_filter($array, function ($a) use($searchBy) { 
    return array_intersect_assoc($searchBy, $a) == $searchBy; 
}); 

See Live Demo

老校版

$find = find($searchBy, $array); 
print_r($find); 

// Function used 
function find($needle, $haystack) { 
    $r = array(); 
    foreach ($haystack as $k => $a) { 
     array_intersect_assoc($needle, $a) == $needle and $r[$k] = $a; 
    } 
    return $r; 
}
