best way to replace a string?

string '/home/adam/Projects/red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg' (length=85)

what i need is just http://localhost/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg

what is the best way doing it ? i mean useing strlen ? substr_replace ? substr ? im a bit confused what is the best way doing this? becouse there is many ways to do this.

edit* there is no newbie tag :|

    // get from database red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg
    $image_path = $this->data['products'][0]['image_small'];
    $exploded = end(explode('/', $image_path));
    $myurl = DOMAIN;
    $myfullurl = $myurl."/storage/".$exploded;

// it works!, but let see the comments maybe there is a better way :)

Here is how you can get the image part:

$str = '/home/adam/Projects/red/storag/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg';
$exploded = end(explode('/', $str));
echo $exploded;

Result:

22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg

Now you can concatenate it with whatever eg:

$new_str = 'http://localhost/storage/' . $exploded;
echo $new_str;

Result:

http://localhost/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg

And It is most likely you want to concatenate the image path with your document root which you do like this:

$img_path = $_SERVER['DOCUMENT_ROOT'] . $exploded;

The idea is that you explode the string with explode function by specifying / as delimiter. This gives you array, now you use the end function to get the ending part of the array which is your image actually.

If the path prefix represents your document root path, then you can do this to strip it:

$path = '/home/adam/Projects/red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg';
$_SERVER['DOCUMENT_ROOT'] = '/home/adam/Projects/red/';
if (substr($path, 0, strlen($_SERVER['DOCUMENT_ROOT'])) === $_SERVER['DOCUMENT_ROOT']) {
    $uriPath = substr($path, strlen(rtrim($_SERVER['DOCUMENT_ROOT'], '/')));
    echo $uriPath;
}

$string = '/home/adam/Projects/red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg';
str_replace('/home/adam/Projects/red', 'http://localost', $string)

This one's pretty much the easiest

str_replace(
  "/home/adam/Projects/red", 
  "http://localhost", 
  "/home/adam/Projects/red/storage/22ff0bc0662bd323891844f6ed342cce2603490ec0_tumb_2.jpg"
);

I suggest you check if the string contains /home/adam/Projects/red, and if it does, you use substr to get the part after it, and you glue it with http://localost.

$path = '/home/adam/Projects/red/storage/*snip*.jpg';
$basePath = "/home/adam/Projects/red";
if (strpos($path, $path) !== false)
    $url = 'http://localhost' . substr($path, strlen($basePath));
