php How to only need the value of the array without the key ?

Get the current array value current()

The current() function returns the array value at the current pointer position in the array. Its form is as follows:

mixed current(array array)

Let’s modify the previous example. This time we want to get the array value:

$fruits = array("apple"=>"red", "banana"=>"yellow");
while ($fruit = current($fruits)) {
   printf("%s <br />", $fruit);
   next($fruits);
}
// red 
// yellow

current() function returns the value of the current element in the array .

Each array has an internal pointer pointing to its "current" element, which initially points to the first element inserted into the array.

Tip: This function does not move the internal pointer of the array.

Related methods:

end() - Point the internal pointer to the last element in the array and output it.

next() - Sets the internal pointer to the next element in the array and outputs it.

prev() - Sets the internal pointer to the previous element in the array and outputs it.

reset() - Set the internal pointer to the first element in the array and output it.

each() - Returns the key name and key value of the current element and moves the internal pointer forward.
