我在多个数组中存储数组如何在数组内计数

Array ( 
[0] => Array ( [table] => items [sku] => LUDM15 ) 
[1] => Array ( [table] => items [sku] => SEZC64 ) 
)

如何计算内部数组计数....

Answer 1

假设

$array1 is Array ( 
[0] => Array ( [table] => items [sku] => LUDM15 ) 
[1] => Array ( [table] => items [sku] => SEZC64 ) 
)

$count = array();
foreach ($array1  as $key => $value) {
    $count[] = count($value);
}

所有计数值都将存储在count数组

中

Answer 2

循环遍历数组，然后count内部数组的长度：

$array = array(array('hi', 'hello'), array('hi', 'hello'), array('hi', 'hello'));
foreach ($array as $singleArray){
  echo 'Count = ' . count($singleArray);
}

Answer 3

$mainArray = array ( 
    [0] => array ( [table] => items [sku] => LUDM15 ) 
    [1] => array ( [table] => items [sku] => SEZC64 ) 
)
foreach ($mainArray as $subArray){
     echo count($subArray);
}

在foreach中，您可以使用单个subArrays的计数执行任何操作。
