从PHP数组中获取特定值的计数

Question

我有一个数组，我想获得具体值的计数。

结构如下：

Array (
    [0] => Array (
        [coupon_id] => 350
        [coupon_title] => This is the title of coupons
        [coupon_code] => ABCD
        [coupon_type] => coupon
    )
    [1] => Array (
        [coupon_id] => 350
        [coupon_title] => This is the title of coupons
        [coupon_code] => ABCD
        [coupon_type] => no_coupon
    )
)

现在我想得到coupon和no_coupon

的统计数字

我试过array_value_count，但我知道这只能计算STRING和VALUES。

Answer 1

<?php
# Get the data from where you want to get the count
$array  = array(
    array('coupon_type' => 'coupon'),
    array('coupon_type' => 'no_coupon')
);

# Count the variables
$count = array_count_values(array_column($array, 'coupon_type')));

print_r($count);
// Will show
// Array ( [coupon] => 1 [no_coupon] => 1 )
?>

Answer 2

您可以使用foreach循环来实现此目的。

      $count_coupon=0;
      $count_no_coupon=0; 

      foreach ( $array as $arr )
      {
      if( $arr['coupon_type'] == 'coupon' )
       {
         $count_coupon++;
       }

       else if( $arr['coupon_type'] == 'no_coupon' )      
       {
         $count_no_coupon++;
       }
