How to Count PHP Array Elements
You can use the count() function in PHP to calculate the number of elements in an array.
The sample code is shown below:
$array = array(1, 2, 3, 4, 5);
$count = count($array);
echo "数组元素个数为: " . $count;
When running the above code, it will output:
数组元素个数为: 5
The count() function can also be used to calculate the number of elements in a multidimensional array, simply by passing the array as a parameter to the count() function.
