each Return the current key and value pair from an array and advance the array cursor &reftitle.description; arrayeach arrayarray 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. &reftitle.parameters; array The input array. &reftitle.returnvalues; 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;. &reftitle.examples; ]]> $bar now contains the following key/value pairs: bob [value] => bob [0] => 0 [key] => 0 ) ]]> "Bob", "Seppo" => "Sepi"); $bar = each($foo); print_r($bar); ?> ]]> $bar now contains the following key/value pairs: Bob [value] => Bob [0] => Robert [key] => Robert ) ]]> each is typically used in conjunction with list to traverse an array, here's an example: 'apple', 'b' => 'banana', 'c' => 'cranberry'); reset($fruit); while (list($key, $val) = each($fruit)) { echo "$key => $val\n"; } ?> ]]> &example.outputs; apple b => banana c => cranberry ]]> Because assigning an array to another variable resets the original arrays pointer, our example above would cause an endless loop had we assigned $fruit to another variable inside the loop. each will also accept objects, but may return unexpected results. Its therefore not recommended to iterate though object properties with each. &reftitle.seealso; key list current reset next prev &foreach; Object Iteration
