How to intercept data output to Yii2 browser?

Question

Yii

Somehow caught a strange glitch. One view outputs data in a stream (updating by ajax). Those. everything is collected there . I'm trying to collect everything in the $out buffer in order to display it according to the if condition. However, for some reason, it starts to display bits of code in the browser with the frequency of the ajax timeout. How to intercept data correctly? <?= $order->lala->topolya; ?>$out = $order->lala->topolya;

Answer 1

try

<?php
ob_start();
echo $order->lala->topolya;
$out = ob_get_clean();
?>
