Previous Comments: ------------------------------------------------------------------------ [2003-07-18 20:18:11] philip@php.net This is actually referring to a situation as shown in example #3 at php.net/list You are not using an array, you are using plain variables, so don't need to worry about it... Not sure how this can be rewritten, how do you think this can be solved? All the examples demonstrate that your code in this report is wrong. ------------------------------------------------------------------------ [2003-05-02 13:09:54] gearond at cvc dot net Dennis Gearon írta: > The documentation of each() says: > > array each ( array array) > -------------------------- > Returns the current key and value pair from the array array and > advances the array cursor.
