    Hello!

    I have images in this name format '78f666f.jpg'

    But I must replace this name with this 78f666f_thumb.jpg

    I must inject the original name '78f666f.jpg' with this piece 78f666f_thumb.jpg

    Do you have any proposal?
    Thanks!

    There will be a nice regex to do this but the clumsy way would be

    $filename = ''78f666f.jpg';
$thumbfilename = str_replace('.','_thumb.',$filename);
    PHP:
    This assumes the names meet the standard of only having one full stop in the name. If there is a chance they might have more but will always be a .jpg then you could do this

    $filename = ''78f666f.jpg';
$thumbfilename = str_replace('.jpg','_thumb.jpg',$filename);

    This should work not matter what the file name is, how many periods it contains or the extension is:

    
<?php
// File name
$name = 'file.a.name.234.jpg';

// Find last position
$position = strrpos($name, '.');

// Replace the . with _thumb.
echo substr_replace($name, '_thumb.', $position, 1);
?>
    PHP:
