It has been used here this way to give you an idea of the alternate way of assigning values to the array. The way we added items to the array is different that we used initially. Output: The count function will count the number of items assigned to the array and that will help us find the total number of students. As we know the best way to learn anything is facilitated by examples, the same way we will have a look in an example to dive deeper on working with an array.Įxample: In this example, we will use count function with the array to find the total number of students in a school. Now in this section, we see how array could be used together with some of the inbuilt functions to get the desired output. In the above sections, we learned how an array is implemented in PHP, the way it stores the value and how we can use the values assigned to the array. In addition to all the features of an array, it’s characteristic of increasing the size automatically makes it favorite among the developers. It automatically detects the data type by analyzing the values or items assigned to it. In PHP, there is no need to assign the data type of the array. By the virtue of array, the program could be made very efficient as it helps to save the memory that is usually consumed by the allocation of variablesįor simple programs, a one-dimensional array could be very helpful and if the program is somewhat complex than a developer can leverage the multi-dimensional array to get the expected outcome. For illustration, in order to store 10 values we will need 10 different variables but by the use of an array in PHP, we can store 10 different values of the same data type in one array. It plays a sheer crucial role in order to make the program less bulky. $array_name will represent "int33" What can you do with PHP Array?Īrray in PHP is very helpful while dealing with complex programs. To access the value stored in two-dimensional array we will use below syntax.Well, just for your information, the complexity of array increases as the dimension of the array increases. Here we will look on two-dimensional array syntax.The values assigned to the multi-dimensional array could be heterogeneous that means values of different data types could be stored in the arrays and it has to be taken care that the sequence of items of specific data types should be same in all the arrays.A multi-dimensional array may be defined as the kind of array that allows us to assign values in multiple arrays at the same time. $array_name could be used to bring “Value3” in use. The way to use the values from the single dimensional array is the same that we have discussed above.The Values assigned in the one-dimensional array are homogenous in nature that means it allows only the values with the same data type to be added to the array.The one-dimensional array may be defined as the type of array that consists of multiple values assigned to the single array.In PHP we have two types of array: one-dimensional array and multi-dimensional array. It shows the order in which values are assigned to the items getting added to the array. Output: The above program will print the name of all the students and below is the output.īelow diagram will make the concept of array very clear to you. Under this section, we will understand how actually the array makes the work easy and we will consider some examples to get a precise view of PHP array’s capability.Įxample: The below illustration will accept the name of several students and will print it. The fact that array makes the working with programs could not be belied. So to use them value1 we have to write it like $array_name. For example, the index value of “value1” is 0. Array_name is the name of the array that we defined in the above syntax.Well, can you guess how could we used the values stored in the array? Let’s go and understand the syntax of how array values could be used. Using the above syntax, we can assign the values to the array.
