php数组的合并与拆分

 <?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);?>
