小弟在wordpress里写了一段程序,大概流程如下:
1、$get_posts_array 调用某分类的文章
$get_posts_array = query_posts(array('posts_per_page'=>$numberposts,'orderby'=>'$orderby','category__and'=>array($sub_cat_id_str)));
2、循环找出文章中的所有图片
foreach ($posts_array as $index => $post_value_array) { if ($post_value_array->post_status == 'publish') { ob_start(); ob_end_clean(); preg_match_all('/<img .+src=[\'"]([^\'"]+)[\'"].* alt="关于php循环输出的问题,求大侠们帮忙!" >/i', $post_value_array->post_content, $pic_rexz); $post_item_array= $post_value_array->ID.'#'.$post_value_array->post_title.'#'.$post_value_array->post_name.'.html#'.$post_value_array->guid.'#'; if (!empty($pic_rexz[1])) { $posts_pic_array[$index] = array_merge($pic_rexz[1],(array)$post_item_array) ; } } }
3、用foreach或if语句输出数组$posts_pic_array时出现问题情况如下:
1、在本机的xampp环境下,用foreach或if语句输出数组 $posts_pic_array都是正常的;
2、上传到服务器上Windows 2008 IIS + PHP5.4的环境下,在文章分类ID=1的时候,循环输出 $posts_pic_array数组,只能打印3条数据。(PS:count($posts_pic_array)数组是有150个记录的)。为什么其他分类都正常,其他分类的$posts_pic_array记录也有50-100条不等啊!foreach或if语句都试验过了,都是只能输出3条记录。
调试了2天啦,希望大家能帮忙!

在线等回复,求解!
if ($post_value_array->post_status == 'publish')
是不是这判断给过滤了?
if ($post_value_array->post_status == 'publish')

测试过了,跟这个没有关系,当分类id=1时,count($posts_pic_array)统计有150条,用print命令也可以打印出数组,但用foreach或for循环时,只能循环出3条,而且更奇怪的是在foreach语句之后的语句是不执行的。是不是会内存溢出之类的问题啊!
问题,找到啦!真的是内存溢出的问题,一个unset语句居然能让128M的php.ini配置溢出!刚才测试了下,删除unset语句就正常了!

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
