ob_get_contents + ob_end_clean vs ob_get_clean

Question

Is there any difference between these two pieces of PHP?

ob_start();
//code...
$pageContent = ob_get_contents();
ob_end_clean();
someFunction($pageContent);
         


        

Answer 1

ob_get_contents() can be used to continue the output buffering.

Example:

ob_start();
echo 'Something!';
$html1 = ob_get_contents();
echo 'More to say!';
$html2 = ob_get_contents();
ob_end_clean();

At the end the vars have this content:

$html1 = 'Something!';
$html2 = 'Something!More to say!';
