![]() ![]() Therefore, with each iteration, variable will move to next index position. Since, while loop will not increment our index variable automatically, we need to increment it inside the loop. The following foreach loop is used for reading the element. We shall go through the following scenarios, with programs. The foreach loop can be used to read the array values only or read both keys and values of the array. The condition will be to continue fetching element from an array til our index values is less than the count of array (or length of the given array). In PHP, foreach is a construct that allows to iterate over arrays easily. Here, we will create an index position variable and start with 0th position which is first in an array. It can also be used to iterate over objects. For example, if you need to have the elements presented. The foreach() method is used to loop through the elements in an indexed or associative array. So, we can use the while loop to change the index position incrementally or decrementally therefore accessing every element (or selective elements as per the condition). For an array, foreach presents the elements of the array in the order that they were added to the array. The PHP arrays have elements which can be accessed via its index position, right? ![]() How to Iterate over PHP array using while loop Keep doing it, until expression becomes false. For example, you may want to display each value in an HTML table, or give each element a new value. It means that, while the given expression (or condition) is true, execute the code inside the curly brackets, and check the expression again. Using foreach to Loop Through PHP Arrays Often you need to move through all the elements in a PHP array so that you can do something with each element’s value. ![]()
