这篇文章主要介绍了php数组合并与拆分方法,实例分析了php中array_merge、array_merge_recursive、array_splice等方法操作数组的相关技巧,需要的朋友可以参考下……

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。
