Retrieve the value of the current element in an array.
| <?php $people = array(“Peter”, “Joe”, “Glenn”, “Cleveland”); echo current($people) . “<br>”; ?> |
The current() function returns the value of the current element in an array.
Each array has an internal pointer to its “current” element, which is initially set to the first element added to the array.
Tip: This function does not alter the array’s internal pointer.
Related functions:
end() – Moves the internal pointer to the last element of the array and returns its value.next() – Advances the internal pointer to the next element of the array and returns its value.prev() – Moves the internal pointer to the previous element of the array and returns its value.reset() – Resets the internal pointer to the first element of the array.each() – Returns the current element’s key and value, and advances the internal pointer forward.| current(array) |
