There are a series of functions in PHP for array traversal that allow us to manipulate arrays very conveniently, to traverse an array, the first step is to point the pointer at the beginning of the array, using the Reset () function.

Use the Prev () and Next () functions to view the previous and next elements of an array. Both the current value and the key () function can be used to get the value of the values.

$array = Array (' foo ' => ' bar ', ' baz ', ' bat ' => 2);
Function Displayarray (& $array) {
reset ($array);
while (the key ($array)!== null) {
echo key ($array). ":". Current ($array). Php_eol;
Next ($array);
}
