This is the example of foreach to capitalize on the chars/strings which are listed in the array and then print them using the foreach loop iteration method.Įcho "List of the items in the array by modifying into capital letters:: \n" Įcho "Array List with Index values:: \n" This is the program to check the number 3 in the list if the number 3 is found then it will print some text as mentioned below and then the loop will be broken. * Small example of dynamic arrays with foreach function*/ * multi-dimensional arrays example with foreach function*/ * key and value listing foreach example*/ All those programs output shown in the output image below in detail. The fifth foreach in the program is to print the dynamic array values. Fourth each in the program is to illustrate multi-dimensional arrays using the foreach function of PHP. The third foreach in the program is made just like the key and value format just like above. The second foreach will print the elements/values of the array with the array index values. The first foreach is declared by listing the array elements/values to the v1 variable by passing from the a1 variable through iteration of foreach. Here we can see different types of foreach loops to illustrate the array’s elements with different types of declarations. This is the small examples of a foreach loop of PHP. Here the array is directly passed inside of the foreach() function and then array values directly passing to the value1 variable through iteration of foreach. This is the program to print the actual array elements and also the array elements which are multiples of 2 of its only values. Then the output will show the array’s index values and the actual value stored in the particular index of an array. After the loop again the new foreach loop stated bypassing the key values to $key1 and values to $value1 and every element we give to key1, value1 variable by using the iteration process of foreach. In the first foreach current elements are multiplied with 2 but didn’t give any output. This is the program to print the array1 elements by passing the array1 values to the value1 at once using iterations of foreach. Array1 which has array elements will be assigned to the value1 variable so that value1 variables current value will become the current element of the array1 by multiplying with the number “2”. This is the first example of foreach to print the list of elements/items which are present in the array itself in the program using foreach function. Examples to Implement Foreach Loop in PHPīelow are some of the examples to implement foreach loop in PHP: Example #1 In foreach, the array’s pointer is advanced by the one so that it will go to the next element in the array/arrays. Foreach also called using the key and value elements as needed. Each and every element/item in the array will be stored in $value/any other variable as needed. The following is the representation of the foreach loop using a flowchart in PHP:įoreach works by looping through the values of the arrays. The second form loop in the above syntax is going to assign the current value to the current key i.e., current elements key is assigned to the $key variable and respect to that current value will be assigned to $value variable on each and every iteration. The first form loop in the above syntax value of the current element in the loop will be assigned to the $value variable and also the internal pointer is advanced ahead by one.
