![]() 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. In the above, the link will be process.phpbcode124. 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 For example, if you need to have the elements presented. PHP Foreach() on an Associative array: "Eric", For an array, foreach presents the elements of the array in the order that they were added to the array. The output of the above code snippet would be: Hire 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. It can also be used to iterate over objects. After going through the first foreach loop, array remains unchanged but, as explained above, value is left as a dangling reference to the last element in. “$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. The foreach() method is used to loop through the elements in an indexed or associative array. It is the array or the variable containing the array. In this example, we will use the other way of using the foreach loop i.e. 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. Foreach loop will work only on PHP7, PHP5, PHP4 versions. Check out below for the different types of syntax usage for the foreach loop in PHP. It can also be used to iterate over objects. There are two kinds of expressing foreach loop in PHP.
