php数组合并与拆分实例分析_php技巧

<&#63;php 
$array1 = array("A","B","C","D"); 
$array2 = array("1","2","3","4"); 
$array3 = array("!","@","#","$"); 
$arrayX = array_merge($array1, $array2, $array3);
//将3个数组合并起来 
print_r($arrayX); 
&#63;> 

<&#63;php 
$array1 = array("AA"=>"A","BB"=>"B","CC"=>"C","DD"=>"D"); 
$array2 = array("AA"=>"1","BB"=>"2","CC"=>"3","DD"=>"4"); 
$array3 = array("AA"=>"!","BB"=>"@","CC"=>"#","DD"=>"$"); 
$arrayX = array_merge($array1, $array2, $array3);
//合并数组 
print_r($arrayX); 
&#63;> 

<&#63;php 
$array1 = array("AA"=>"A","BB"=>"B","CC"=>"C","DD"=>"D"); 
$array2 = array("AA"=>"1","BB"=>"2","CC"=>"3","DD"=>"4"); 
$array3 = array("AA"=>"!","BB"=>"@","CC"=>"#","DD"=>"$"); 
$arrayX = array_merge_recursive($array1, $array2, $array3);
//合并数组 
print_r($arrayX); 
&#63;> 

<&#63;php 
$array = array(1,2,3,4,5,6,7,8,9); 
$arrayX = array_splice($array, 2, 6);
//获取数组的第2个元素到第7个元素 
print_r($array); 
print_r($arrayX);
