php数组合并与拆分实例分析
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。
