![]() Code Output:Īrray ( => mike => john => rocky => scarlett ) It is TRUE and FALSE.Įxample 4.1: This example shows how to use the print_r() function to print an array. The print_r() has two parameters but the second parameter is optional. The syntax is very simple, we use the array name as a parameter inside this function. ![]() This function print PHP arrays in a structured format. The print_r() function is mostly used for testing purposes. But when the array is too long, then we use loops and other methods to display it. In that case echo statement really helps. Sometimes, we need to display array values in different ways like inside HTML tables. The above code output will look like this in your browser: Code Output: We can access each element of an array using its index number. Remember, the index number of an array starts from 0. And also, I added a tag to display each value of an array on a new line. I used an echo statement with an array name and index number on each line. Now, let’s see the PHP code to print an array using echo statements.Įxample 3.1: This example will show you how to use an echo statement to print all the values of an array one by one. While in terms of arrays, echo is not the only solution but it is still helpful in many cases.įor example, echo helps a lot when we want to print a single value of an array. In PHP, whenever we want to print something, we use echo statements. The echo statement is useful in some cases, now let’s see that in the next method. But there is an echo statement that we use mostly to print a single array element. We use these variables inside the loop to print the keys and values of an associative array. You can give any name to $key and $value variables, these variables will hold the value of named indexes and their values.In that Foreach loop, I used the array name ($students) with $key and $value variables. And the indentation you’re seeing is optional, you can write the associative array on just 1 line. The length of the above-indexed array is 4 which starts from 0. 5, in the above code, I used the count() function to get the length of an array in numbers and stored it in a variable ( $arrlength). Now, let’s print all the values of an array using for loop. In this example, I will create an indexed array with the name $students. Also, you can print each array element on a new line or inside the HTML table. By using a loop, you can print all the values of an array at the same time in different ways.įor example, you can use this PHP method to print an array line by line. Using for loop is the most suitable way to print PHP array content. Tip: Don’t know how to run PHP on your PC? See this guide on how to run PHP code. Not just simple indexed arrays, examples to print associative arrays, and multi-dimensional arrays are also included in this guide. In PHP, We use the Following 6 Methods to Print Arrays :Īlso, you will learn each method with an example. And we’re going to discuss all that in this tutorial. And in PHP, we have various methods to print arrays. Whether it’s an indexed array, associative array, or multidimensional array, you’ll see each of them in this all-in-one guide.Īrrays are very useful when we want to store multiple values in one variable. You will know how to print array values in different ways using these methods. You’ll see all 6 easy methods with examples. In associative array of array_search, the key of an array will be printed.In this PHP tutorial, you’ll learn how to print an array. So, if the user wants to search exact integer value in an array then it must write a true parameter.Īrray_search in indexed array: array_search in indexed array returns its index number. If int value is written in quotes in array function: Įxplanation: if a user does not add a true parameter, the result will be ‘found’ even though 45 written in an array is a string, and in if function it is written as an integer because without quotes. If an array is like an associative array, the result will print its key. If the array is the index, the result will print the index. If we use the array_search function, it will give us the index of an array or its key. ![]() If the given word is not in the array, the result will be 0. If the given word is in the array function, the result will be 1. If we use in_array, it will only give results as 0 and 1. To do this, in PHP, we have 2 arrays named: For example, in the below code we want to search ‘mango’. PHP search arrays are used to search arrays. This will count all arrays of $food variable. Php sizeof() function also returns the number of values. ![]() By default, the index starts with zero.Įxample: , These type of arrays can be used to store any type of elements, but the index is always a number. It is the simplest form of a multidimensional array.
