Output the value of the current element in the array:
<?php$people = array("Peter", "Joe", "Glenn", "Cleveland");echo pos($people) . "<br>";?>The pos() function returns the value of the current element in the array.
This function is an alias of the current() function.
Each array has an internal pointer pointing to its "current" element, initially pointing to the first element inserted into the array.
Tip: This function does not move the array internal pointer.
Related methods:
current() - Returns the value of the current element in the array.
end() - Sets the internal pointer to the last element in the array and outputs 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() - Sets the internal pointer to the first element in the array and outputs it.
each() - Returns the key name and value of the current element and moves the internal pointer forward.
