Real nude model photography scene. Classic method in PHP to determine whether a multi-dimensional array is empty.

Copy code The code is as follows:

//Determine whether an array is empty
/**
array(
); empty
array(
array(
),
array(
),
array(
)
); empty
array(
array(
),
array(
array(
),
array(
1=>1
)
),
array(
)
); non-null
*/
function is_array_null($value)
{
if (empty($value))
{
return $value;
}
else
{
return is_array($value) ? array_map('array_null', $value) : addslashes($value);
}
}

The above introduces the classic method in PHP to determine whether a multi-dimensional array is empty, including the actual nude model photography scene. I hope it will be helpful to friends who are interested in PHP tutorials.
