将结果加载到缓冲区而不回显浏览器

Question

How can I load loop results into a buffer using the PHP output control functions without echoing the results to the browser? In essence, what I'm trying to do is call results from the buffer as opposed to echoing my way through the loop "as it goes". Is it possible to do this? Any help appreciated. Thanks!

Answer 1

Use ob_get_contents to get the buffer contents without sending them.

To clean out the buffer call ob_end_clean

To do both in one step call ob_get_clean

An example would be

ob_start();
foreach ($results as $result){
     include("tmplate/to/render/a/result.php");
}
$resultHTML = ob_get_clean();

Then later.

<div class='left-rail'><?= $resultHtml ?></div>
