What you want to do is pass the array to the has_next() function via reference. This is true, but the array you are manipulating in your has_next() function will have it's pointer set to the first element, not the same position as the original array. "Since you do not pass the array by reference, its pointer is only moved inside the function." Papipo's function below is usefull in concept but does not work. There are a lot Methods like array_merge($array) that will neither reset the pointer of $array nor copy the pointer to $array2. The php-functions seems to reset the pointer on the given position after walk through (i don't know the internal handling - there could be used a copy of the array, too): What's more is, that foreach not resetting the pointer after walk through: Have a look at your array pointer if you copy an array - the pointer will be copied, too.īut if you copy the array after you've setted the pointer, the pointer will be copied, too: PHP: 5.2.10-2ubuntu6.3 (default apt-get installation on actual, see Date, jaunty 9.10 Ubuntu Distro - G33kWoRDs) $arHeighbor = $arRelated Įcho '' print_r ( $arHeighbor ) echo '' If( $arRelated = array_neighbor ( $count, $key, $arRelated )) This is an improved version of the same function posted earlier. If the specified $key points to the last or first element of the array, the first or last keys of the array will be returned consecutively. This function will return the previous,next neighbors of an array entry within an associative array.
