Name
prev
Synopsis
mixed prev(array array
)
Moves the internal pointer to the element before its current location
and returns the value of the element to which the internal pointer is
now set. If the internal pointer is already set to the first element
in the array, returns false
. Be careful when
iterating over an array using this function—if an array has an
empty element or an element with a key value of 0
,
a value equivalent to false
is returned, causing
the loop to end. If an array might contain empty elements or an
element with a key of 0
, use the each( )
function instead of a loop with prev( )
.
