push - append one or more elements to an array
push
ARRAY,LIST
Treats
ARRAY as a stack, and pushes the values of
LIST onto the end of
ARRAY. The length of
ARRAY increases by the length of
LIST. Has the same effect as
for $value (LIST) {
$ARRAY[++$#ARRAY] = $value;
}
but is more efficient. Returns the new number of elements in the array.
