Code Examples

each( array|objectarray ): array

Return the current key and value pair from an array and advance the array cursor.

After each has executed, the array cursor will be left on the next element of the array, or past the last element if it hits the end of the array. You have to use reset if you want to traverse the array again using each.

Parameters

array

The input array.

Return Values

Returns the current key and value pair from the array array. This pair is returned in a four-element array, with the keys 0, 1, key, and value. Elements 0 and key contain the key name of the array element, and 1 and value contain the data.

If the internal pointer for the array points past the end of the array contents, each returns false.
