Question

I was using the strrchr PHP function with substr and strrpos to find the file name in a string with the full path like:

/images/onepiece.jpg returns
onepiece.jpg

but now I need to a function to find not the last “/” but the one next to the last:
/images/anime/onepiece.jpg returning anime/onepiece.jpg or /anime/onepiece.jpg
And as strrchr – 1 doesn’t work, hehehe :), how can I achieve that?

Using PHP pathinfo() as @middaparka and @Shakti Singh said, I’ve change the way I get the image string from the MySQL database. Now it can have subfolders, as was my initial intention.

<?php
/*
 * pathinfo() parameters:
 * PATHINFO_DIRNAME = 1
 * PATHINFO_BASENAME = 2
 * PATHINFO_EXTENSION = 4
 * PATHINFO_FILENAME = 8
 * */
    $slash = '/';
    $mainpath = 'store/image/';
    $thumbspath = 'cache/';
    $path = $imgsrow->photo; //gets the string containing the partial path and the name of the file from the database
    $dirname = pathinfo($path, 1); //gets the partial directory string
    $basename = pathinfo($path, 2); //gets the name of the file with the extension
    $extension = pathinfo($path, 4); //gets the extension of the file
    $filename = pathinfo($path, 8); //gets the name of the file
    $dims = '-100x100.'; //string of size of the file to append to the file name
    $image = $mainpath . $path; //mainpath + path is the full string for the original/full size file
    $thumbs = $mainpath . $thumbspath . $dirname . $slash . $filename . $dims . $extension; //string to point to the thumb image generated from the full size file
?>
    <img src="<?= $thumbs; ?>" width="100" height="100" alt="<?= $row->description; ?>" />
    <br />
    <img src="<?= $image; ?>" width="500" height="500" alt="<?= $row->description; ?>" />

To be honest, it would be a lot easier to use the pathinfo or dirname functions to decompose directory paths.

For example:

$filename = pathinfo('/images/onepiece.jpg', PATHINFO_BASENAME);
$directory = dirname('/images/onepiece.jpg');

You may have to use a mix of these to obtain what you’re after but they will at least be OS “safe” (i.e.: will handle both Linux/Linux and Windows path styles).

In terms of the specific problem you have, you should be able to use the following cross-platform solution to get what you need:

<?php
    $sourcePath = '/images/anime/onepiece.jpg';

    $filename = pathinfo($sourcePath, PATHINFO_BASENAME);
    $directories = explode(DIRECTORY_SEPARATOR, pathinfo($sourcePath, PATHINFO_DIRNAME));

    echo $directories[count($directories) -1] . DIRECTORY_SEPARATOR . $filename;
?>
