Get php array length1/23/2024 The second method you can use to calculate the length of an array in PHP is the sizeof function. Get the length of an array using sizeof function To get the total number of elements in an array, you may use the PHP count or sizeof functions. To calculate the length of a multi-dimensional array, like the one shown below, Using count function in a multi-dimensional array Introduced in PHP 4, though mode parameter used for multidimensional arrays only appeared in PHP 4.2. The result of the above function will also be 3 This function is used to get the number of elements in an array (in other words, to get PHP array length). ![]() It takes a string as a parameter and returns its length. The strlen() is a built-in function in PHP which returns the length of a given string. To calculate the length of an associative array, for example, In this article, we will see how to get the length of the string using strlen() function in PHP, along with understanding its implementation through the examples. Using count function in an associative array To calculate the size of this indexed array using the count function, use this code below Example 1: This example illustrates the count of the number of elements in the one-dimensional array. We will understand the concept of the sizeof () function through the examples. $computerbrands=array("HP","Samsung","Toshiba") Return Value: This function returns an integer value as shown in the syntax which represents the number of elements present in the array. Elements in an array are separated using a comma (,). The count function returns a single numerical value which is the result of the number of elements in an array. The count () and sizeof () function returns 0 for a variable that has been initialized with an empty array, but it may also return 0 for a variable that isn't set. ![]() You can simply use the PHP count () or sizeof () function to get the number of elements or values in an array. ![]()
