Why does php only need the values of the array without keys?

Gets the current array value current ()

The current () function returns the array value of the position of the current pointer in the array. It takes the following form:

Mixed current (array array)

Let's modify the previous example, this time we want to get the array values:

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

Related introduction:

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

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

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

Related methods:

End ()-points the internal pointer to the last element in the array and outputs it.

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

Prev ()-points the internal pointer to the last element in the array and outputs it.

Reset ()-points the internal pointer to the first element in the array and outputs it.

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