PHP返回关联数组，通过多元素搜​​索？

Question

我有一个看起来像这样的数组：

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

我想通过给定的值来检查：

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

我想要实现的是返回具有所有关联键的父数组＆amp;值对匹配。我已经尝试了in_array()但它不起作用..

Answer 1

array_filter可能会更好：

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

Answer 2

您可以尝试：

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

See Live Demo

旧学校版

$find = find($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;
}
