Проблема с парсингом?

$src = '';
	$content = file_get_contents($src);
	$pos = strpos($content, '<div class="task-img-container">');
	$content = substr($content, $pos);
	$pos = strpos($content, '</figure>');
	$content = substr($content, 0, $pos);
	$content = str_replace('<div class="task-img-container">','', $content);
	$content = str_replace('title=""','id="loadable-img" class="img-fluid mx-auto d-block"', $content);
	$content = str_replace('</div>','', $content);
	$content = str_replace('<div id=\'media-11\' class=\'media media-task-image\'>','', $content);
	echo $content;
