The sum of array element is = 15 PHP foreach loop example for find out odd and even elements from an array. foreach (PHP 4, PHP 5, PHP 7, PHP 8) The foreach construct provides an easy way to iterate over arrays. The following foreach loop is used for reading the element. This is obviously very easy with a foreach (), but where I start breaking down is when arrays contain arrays. The foreach loop can be used to read the array values only or read both keys and values of the array. As foreach relies on the internal array pointer in PHP 5, changing it within the loop may lead to unexpected behavior. This means that you do not need to call reset() before a foreach loop. The output is : 3 6 9 12 15 PHP foreach example PHP foreach () with arrays within arrays Ask Question Asked 12 years, 3 months ago Modified 12 years, 3 months ago Viewed 28k times Part of PHP Collective 15 I want to call a function on each element in an array. In PHP 5, when foreach first starts executing, the internal array pointer is automatically reset to the first element of the array. In above example first we declare array with five elements, foreach loop assigned all element of array one by one to $value and echo statement print $value, so the foreach loop repeat five times and we get result : 12345 Example of foreach loop List() is a function that does the opposite of array() - it takes an array, and converts it into individual variables. In foreach loop each element of array is assigned to $value and we can use $value in program then assigned each element one by one to $value from an array.
