php数组合并与拆分实例分析

本文实例讲述了php数组合并与拆分的方法。分享给大家供大家参考。具体如下：

<?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); 
?> 

<?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); 
?> 

<?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); 
?> 

<?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); 
?>

希望本文所述对大家的php程序设计有所帮助。
