Php array contains3/3/2024 ![]() Let's look at an example with a PHP array that holds names of different guitar manufacturers. Sort() function sorts an array in an ascending order. To PHP sort array by value, you will need functions asort() and arsort() (for ascending and descending orders). To PHP sort array by key, you should use ksort() (for ascending order) or krsort() (for descending order). There are four functions for associative arrays - you either array sort PHP by key or by value. First, we have the sort() method used to array sort PHP code in an ascending order. Let's look at the various PHP array sorting functions. It's possible to array sort PHP by key or by value, in numerical, alphabetical, descending and ascending orders.Some of the functions can only be used for associative arrays.PHP offers multiple built-in functions for PHP array sorting.ConclusionĪt this point you should be able to use the three different types of arrays when working on a PHP project. Using the method above, you can access and display any information in the array from the code above. ![]() In our case it will display I want to access the Email of the staff in the first array, we'll do the following: The echo $staff displays the email of the staff that falls into the index of 2. The code above is an example of a multidimensional array because it contains more than one array (an array of arrays) with one single variable of $staff. Remember, an array starts counting from index 0. you can access the information of any staff you wish to by using echo $(variable name). 'Email' => $Staffs // This displays the email of the last staff which is $staffs //This displays the Name of the staff in the first array (index 0) which is Derek Emmanuel We can use multidimensional arrays to archive this. Suppose we want to store the Names, Registration Numbers, and Emails of some of the staff working in a particular company. In general, multidimensional arrays allow you to store multiple arrays in a single variable. This means that every element in the array holds a sub-array within it. You can think of a multidimensional array as an array of arrays. The values of the array are 17, 18, 16, and 17. The keys of the array are scott_Mcall, Stalenski, Lydia, Allision, and we used them to assign the age to each student. The code above is an example of an associative array. For example: 17,Įcho $student_age //this code will display the age of Scot_Mcall as 17Įcho $student_age //this code will display the age of stalenski as 18Įcho $student_age //this code will display the age of Lydia as 16Įcho $student_age //this code will display the age of Allision as 17 We can use the Associative array method to get it done. Suppose we want to assign ages to a group of high school students with their names. When you want to store the score of a student in different subjects. ![]()
