PHP 多维数组搜索(按特定值查找键)
我有这个多维数组。我需要搜索它并仅返回与“slug”的值匹配的键。我知道还有其他关于搜索多维数组的线索,但我对它的理解还不够,无法应用于我的情况。非常感谢您的任何帮助!
所以我需要一个这样的函数:
myfunction($products,'breville-one-touch-tea-maker-BTM800XL');
// returns 1
下面是数组:
$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',
'image' => '41y2B8jSKmwL.jpg',
'related1' => '3',
'related2' => '4',
'related3' => '5',
'bestbuy' => '1',
'quote' => '',
'quoteautor' => '',
),
);
