<?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); ?>
