Question

I have a string like this

folder1/folder2/folder3/13007805372971.jpg

What should I do to append a string before file name ? I would like to look like this

folder1/folder2/folder3/sometext_13007805372971.jpg

Answer 1

You can make use of the pathinfo function, which is designed to parse paths.

$s='folder1/folder2/folder3/13007805372971.jpg';
$x='sometext_';
$fos=pathinfo($s);

$s2=$fos['dirname'].DIRECTORY_SEPARATOR.$x.$fos['basename'];
