PHP - 添加到数组

Question

如何添加到每个子数组的末尾？这是一个例子.

$products = array( 
 array( Code => 'TIR', 
  Description => 'Tires', 
  Price => 100 
 ),
 array( Code => 'OIL', 
  Description => 'Oil', 
  Price => 10 
 ),
 array( Code => 'SPK', 
  Description => 'Spark Plugs', 
  Price =>4 
 ) 
);

我想在每个数组中的Price之后添加SKU => 1234.谢谢

遍历数组并使用引用来修改它:

foreach ($products as &$v) {
  $v['SKU'] = 1234;
}
