In this article, we explored PHP’s array length with many examples, and also, we have also seen more about multi-dimensional arrays. Depends upon the developer, the methods are picked while writing the code. There is no difference between the count and size of the function. Here we have seen how to determine the length or size of an array in PHP and also the various methods to show how PHP functions are used to take memory size used by the array. Finally, count the number of words in a paragraph.Here an array is created using explode function to split the array.The above program Stores a paragraph in a variable of type String.In the above code, we have used mode count as ‘1’ therefore, this multi-dimensional array counts the value as ‘9’.'Candy Craze'), 'Fast Food' => array('Nuggets', 'Salad Platters')) So the output looks like this.Ĭode: array('Diary Milk', 'Cadbury Godiva', 'Nestle','Snikkers', The above code returns a parameter array as the value is assigned as null.The output shows the list of values in an array in each iteration.The above code takes the length of an array using the sizeof function, and the array elements are iterated using for-loop.The above code determines the General count as ‘3’ and the array length of recursive mode to be ‘8’.sizeof($bike)."" Įcho "Recursive Number: ". Determines an array length with the count of ‘1’.Įcho "General count: ".count($program)."" Įcho "Multidimensional count: ". First, we had created an array of ‘flowers’, and in the next line, we used the count command.Ĭode: ,.When we execute the above code snippets, the output is shown as ‘3’ as the array elements have 3 elements.Example #1Ĭreating a simple array to count the elements. Let’s see how these methods used to determine the length in the following examples. Two methods define PHP array length or size count. Even though it is similar to the count () function, most of them stick to the count() function. But most programmer developers pretend to use count () instead of sizeof() as it returns the memory size. Care should be taken when using for loop in count () method as PHP lacks in differentiating indexed array and associative array. So, in each iteration step, the value gets incremented by 1. The values should loop continues to execute. To perform iteration in array elements, we can use for-loop for iteration. The above code displays the output as ‘7’ instead of the value ‘6’. In this case, the length of an array is determined differently.Ĭode: $avar = array (2,6,7, array (19,18,60)) The second case is when we count the elements using parameter mode, to perform this, we have passed a constant ‘recursive’ as a parameter to count the elements. We have used PHPs native function count, so when we execute the above snippets, the output of the function is ‘4’. In the above sample code, we have used a one-dimensional array. So here, a count function returns the number of elements in an Object and simply counted in an associative array. PHP has two in-built functions, namely count and size of.Įcho " The size is given as =", count($a1) As the number of elements changes concerning user requirements in our code, it is very important to see the actual length of the array list.
