php函数array_merge用法一例(合并同类数组)

　　$arr1 = $dblink->mem_fetch_array ( "SELECT t_pid,imgname,invented,score FROM `t_sum_giftimg` where t_pid=3 or t_pid=6", 0 );

　　$arr2 = $dblink->mem_fetch_array ( "SELECT t_pid,imgname,invented,score FROM `t_sum_giftimg` where t_pid=10 or t_pid=12", 0 );

　　$imgInfo = array_merge ( $arr1, $arr2 );

　　if ($imgInfo) {

　　foreach ( $imgInfo as $imgInfo ) {

　　$imgs [] = $imgInfo;

　　}

　　}
