Regarding the problem of php loop output, please help me!
I wrote a program in wordpress. The general process is as follows: 1. $get_posts_array calls articles of a certain category $get_posts_array = query_posts(array(‘posts_per_page’=>$numberposts,’orderby’=>’$orderby’,’category__and’=>array($sub_cat_id_str))); 2. Loop to find all the pictures in the article foreach ($posts_array as $index => $post_value_array) { if ($post_value_array- >post_status == ‘publish’) { ob_start(); ob_end_clean(); preg_match_all(‘// 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. The problem occurs when using foreach or if statement to output the array $posts_pic_array as follows: 1. In the local xampp environment, use foreach or if statement to output the array $posts_pic_array is normal; 2. In the environment of Windows 2008 IIS + PHP5.4 when uploaded to the server, when the article category ID=1, the $posts_pic_array array is output in a loop and can only be printed. 3 pieces of data. (PS: The count($posts_pic_array) array has 150 records). Why are other categories normal, but the $posts_pic_array records of other categories also have 50-100 records? I have tried the foreach or if statements, but they can only output 3 records. I have been debugging for 2 days, I hope you can help!
