Ds \ Sequence::reversed()函數是PHP中的一個內置函數,用於返回序列元素的反向副本。
用法:
Ds\Sequence abstract public Ds\Sequence::reversed ( void )
參數:該函數不接受任何參數。
返回值:此函數返回序列元素的反向副本。
以下示例程序旨在說明PHP中的Ds \ Sequence::reversed()函數:
程序1:
<?php
// Create new Sequence
$seq = new \Ds\Vector([1, 2, 3, 4, 5]);
// Display the sequence elements
print_r($seq);
echo("After reversing the sequence elements\n");
// Use reversed() function to reverse
// the copy of sequence and display it
print_r($seq->reversed());
?>
輸出:
Ds\Vector Object ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 ) After reversing the sequence elements Ds\Vector Object ( [0] => 5 [1] => 4 [2] => 3 [3] => 2 [4] => 1 )
程序2:
<?php
// Create new Vector
$seq = new \Ds\Vector(["Geeks", "for", "Geeks",
"Computer", "Science", "Portal"]);
// Display the elements
print_r($seq);
echo("Sequence after reversing\n");
// Use reversed() function to reverse
// the element and display it
print_r($seq->reversed());
?>
輸出:
Ds\Vector Object ( [0] => Geeks [1] => for [2] => Geeks [3] => Computer [4] => Science [5] => Portal ) Sequence after reversing Ds\Vector Object ( [0] => Portal [1] => Science [2] => Computer [3] => Geeks [4] => for [5] => Geeks )
