Once you have understood the working to the foreach() method try working with the for loop. Additionally, the foreach() method does not modify the values of the internal pointer. The foreach() method would return an error in case you use it on variables with a different data type. Additionally, we replaced “=>” with a “:” to make it more readable. Now let’s look at a case where we pass a second argument.Īs you can see the key and the values of the associative array were printed. The output of the above code snippet would be: name: Eric PHP Foreach() on an Associative array: "Eric", The output of the above code snippet would be: Hire For example, if you need to have the elements presented. ![]() In this section, we first look at how the foreach() function works on an indexed array followed by which we look at it’s working on an associative array. For an array, foreach presents the elements of the array in the order that they were added to the array. ![]() “$value” is a variable that stores the current element in each iteration.Īssociated array, uses keys and values, and hence the $key & $values in the second syntax represent the same accordingly. It is the array or the variable containing the array. Here, “Iterable” is the required parameter. The syntax for associative arrays: foreach (iterable as $key => $value) The syntax for indexed arrays is as given in the following code block: foreach (iterable as $value) The foreach() method has two syntaxes, one for each type of array. This allows you to run blocks of code for each element. It can also be used to iterate over objects. The foreach() method is used to loop through the elements in an indexed or associative array.
