PHP Ds\Vector merge()用法及代码示例

Ds \ Vector::merge()函数是PHP中的内置函数，用于将所有元素合并到向量中。

用法:

Ds\Vector public Ds\Vector::merge( $values )

参数：此函数接受单个参数$values，它是可遍历的对象或数组。

返回值：在将元素合并到向量后，此函数返回向量的副本。

以下示例程序旨在说明PHP中的Ds \ Vector::merge()函数：

程序1:

<?php 
  
// Create new vector 
$arr1 = new \Ds\Vector([10, 20, 30, 40, 50]); 
  
echo("Original vector elements\n"); 
print_r($arr1); 
  
// Create new vector 
$arr2 = new \Ds\Vector([60, 70, 80, 90, 100]); 
  
echo("Vector Elements after merging\n"); 
  
// Use merge() function to merge two vector  
// and display its resultant vactor 
print_r($arr1->merge($arr2)); 
  
?>

输出：

Original vector elements
Ds\Vector Object
(
    [0] => 10
    [1] => 20
    [2] => 30
    [3] => 40
    [4] => 50
)
Vector Elements after merging
Ds\Vector Object
(
    [0] => 10
    [1] => 20
    [2] => 30
    [3] => 40
    [4] => 50
    [5] => 60
    [6] => 70
    [7] => 80
    [8] => 90
    [9] => 100
)

程序2:

<?php 
  
// Create new vector 
$arr1 = new \Ds\Vector(["geeks", "for", "geeks"]); 
  
echo("Original vector elements\n"); 
print_r($arr1); 
  
// Create new vector 
$arr2 = new \Ds\Vector([60, 70, 100]); 
  
echo("Vector Elements after merging\n"); 
  
// Use merge() function to merge two vector  
// and display its resultant vactor 
print_r($arr1->merge($arr2)); 
  
?>

输出：

Original vector elements
Ds\Vector Object
(
    [0] => geeks
    [1] => for
    [2] => geeks
)
Vector Elements after merging
Ds\Vector Object
(
    [0] => geeks
    [1] => for
    [2] => geeks
    [3] => 60
    [4] => 70
    [5] => 100
)
