PHP多维数组搜索(按特定值查找键)我有这个多维数组。我需要搜索它并只返回匹配“slug”值的键。我知道还有其他关于搜索多维数组的线程,但我并不是真正了解它以适用于我的情况。非常感谢您的帮助!所以我需要一个像以下的功能:myfunction($products,'breville-one-touch-tea-maker-BTM800XL');// returns 1这是阵列:$products = array (1 => array(
'name' => 'The Breville One-Touch Tea Maker',
'slug' => 'breville-one-touch-tea-maker-BTM800XL',
'shortname' => 'The One-Touch Tea Maker',
'listprice' => '299.99',
'price' => '249.99',
'rating' => '9.5',
'reviews' => '81',
'buyurl' => 'http://www.amazon.com/The-Breville-One-Touch-Tea-Maker/dp/B003LNOPSG',
'videoref1' => 'xNb-FOTJY1c',
'videoref2' => 'WAyk-O2B6F8',
'image' => '812BpgHhjBML.jpg',
'related1' => '2',
'related2' => '3',
'related3' => '4',
'bestbuy' => '1',
'quote' => '',
'quoteautor' => 'K. Martino',
),2 => array(
'name' => 'Breville Variable-Temperature Kettle BKE820XL',
'slug' => 'breville-variable-temperature-kettle-BKE820XL',
'shortname' => 'Variable Temperature Kettle',
'listprice' => '199.99',
'price' => '129.99',
'rating' => '9',
'reviews' => '78',
'buyurl' => 'http://www.amazon.com/Breville-BKE820XL-Variable-Temperature-1-8-Liter-Kettle/dp/B001DYERBK',
'videoref1' => 'oyZWBD83xeE',

此类方法可以通过多个条件在数组中搜索:
class Stdlib_Array{ public static function multiSearch(array $array, array $pairs) { $found = array(); foreach ($array as $aKey => $aVal) { $coincidences = 0; foreach ($pairs as $pKey => $pVal) { if (array_key_exists($pKey, $aVal) && $aVal[$pKey] == $pVal) { $coincidences++; } } if ($coincidences == count($pairs)) { $found[$aKey] = $aVal; } } return $found; } }// Example:$data = array( array('foo' => 'test4', 'bar' => 'baz'), array('foo' => 'test', 'bar' => 'baz'), array('foo' => 'test1', 'bar' => 'baz3'), array('foo' => 'test', 'bar' => 'baz'), array('foo' => 'test', 'bar' => 'baz4'), array('foo' => 'test4', 'bar' => 'baz1'), array('foo' => 'test', 'bar' => 'baz1'), array('foo' => 'test3', 'bar' => 'baz2'), array('foo' => 'test', 'bar' => 'baz'), array('foo' => 'test', 'bar' => 'baz'), array('foo' => 'test4', 'bar' => 'baz1'));$result = Stdlib_Array::multiSearch($data, array('foo' => 'test4', 'bar' => 'baz1'));var_dump($result);
会产生:
array(2) { [5]=> array(2) { ["foo"]=> string(5) "test4" ["bar"]=> string(4) "baz1" } [10]=> array(2) { ["foo"]=> string(5) "test4" ["bar"]=> string(4) "baz1" }}

非常简单:
function myfunction($products, $field, $value){ foreach($products as $key => $product) { if ( $product[$field] === $value ) return $key; } return false;}
