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); 
    ?>
