Below programs illustrate the SplFixedArray::rewind() function in PHP:
Program 1:
<?php // Create a fixed size array $gfg = new SplFixedArray(6);
$gfg [0] = 1;
$gfg [1] = 5;
$gfg [2] = 10;
// Move to next index $gfg ->next();
$gfg ->next();
// Print result before rewind echo $gfg ->current(). "\n" ;
// Using rewind function $gfg -> rewind ();
// Print result after rewind echo $gfg ->current(). "\n" ;
?> |
Output:
10 1
Program 2:
<?php // Create some fixed size array $gfg = new SplFixedArray(6);
$gfg [0] = 1;
$gfg [1] = 5;
$gfg [2] = 1;
$gfg [3] = 11;
$gfg [4] = 15;
$gfg [5] = 17;
$i = 0;
// Iterate array and print values while ( $i < 6) {
// Using rewind function
// it will rewind each time at initial index
$gfg -> rewind ();
// Print current value of index of the array
echo $gfg ->current(). "\n" ;
// Move next each time of iteration
$gfg ->next();
$i ++;
} ?> |
Output:
1 1 1 1 1 1
