In PHP, the length of an array can be expressed in many ways. Below we will introduce these methods respectively:
The count function in PHP can be used to return the number of elements in the array, which is the length of the array. For example, the following example demonstrates how to use the count function to obtain the length of an array:
$myarray = array("apple", "banana", "pear", "orange"); $length = count($myarray); echo "数组的长度为:" .$length;
Running the above code will output:
数组的长度为:4
$myarray = array("apple", "banana", "pear", "orange"); $length = sizeof($myarray); echo "数组的长度为:" .$length;
$myarray = array("apple", "banana", "pear", "orange"); $length = $myarray->count; echo "数组的长度为:" .$length;
$myarray = array("apple", "banana", "pear", "orange"); $length = $myarray->count(); echo "数组的长度为:" .$length;Summary: The above are several ways to obtain the length of an array in PHP, including using the count function , sizeof function, count attribute and the count method that comes with the array. No matter which method is used, you can easily get the length of the array, making it easier to perform array operations.
