PHP reset

PHP original manual for reset [ show | php.net ]


(PHP 4, PHP 5, PHP 7)

resetSet the internal pointer of an array to its first element


mixed reset ( array &$array )

reset() rewinds array's internal pointer to the first element and returns the value of the first array element.



The input array.

Return Values

Returns the value of the first array element, or FALSE if the array is empty.


This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.


Example #1 reset() example


= array('step one''step two''step three''step four');

// by default, the pointer is on the first element
echo current($array) . "<br />\n"// "step one"

// skip two steps
current($array) . "<br />\n"// "step three"

// reset pointer, start again on step one
current($array) . "<br />\n"// "step one"



Note: The return value for an empty array is indistinguishable from the return value in case of an array which has a boolean FALSE first element. To properly check the value of the first element of an array which may contain FALSE elements, first check the count() of the array, or check that key() is not NULL, after calling reset().
