![]() ![]() Unfortunately array_push returns the new number of items in the array which will result in an array that looks like this. Note that like array_push (but unlike $array =) the array must exist before the unary union, which means that if you are building an array in a loop you need to declare an empty array first. You can also, of course, append more than one element at once. If you want to add elements to the END of an associative array you should use the unary array union operator (+=) instead. In many cases it won't matter if the array is not stored internally in the same order you added the elements, but if, for instance, you execute a foreach on the array later, the elements may not be processed in the order you need them to be. I can only assume that PHP sorts the array as elements are added to make it easier for it to find a specified element by its key later. ![]() might very well result in an array that looks like this. Rodrigo's suggestion is NOT guaranteed to append the new element to the END of the array. Rodrigo de Aquino asserted that instead of using array_push to append to an associative array you can instead just do.
