How to slice an input value?

Question

My input value is just like this: Oppa/upload/default.jpeg

I want to slice the value of an input according by / cause i want to get the image file name. Does anyone know some tricks to do this?

example: i want to get default.png

<input type="text" value="Oppa/upload/default.png" id="fileLink" name="fileLink" />

Seriously! You've never come across PHP's [explode()](http://www.php.net/manual/en/function.explode.php) function before? — Mark Baker, Jul 19 '14 at 12:53
If you don't validate this properly on the backend you could cause yourself a world of troubles. That being said, you're probably looking for explode(). — Ryan Kempt, Jul 19 '14 at 12:53

Use basename():

$path = "Oppa/upload/default.jpeg";
echo basename($path); //will output "default.jpeg"
echo basename($path, '.jpeg'); //will output "default"

The first parameter is the path of which the trailing component will be removed. If the first parameter ends in the optional second parameter, the second parameter will also be cut off.

On Windows, both slash (/) and backslash (\) are used as directory separator character. In other environments, it is the forward slash (/). - PHP manual

Use pathinfo() php function

$path = "http://domain.tld/Oppa/upload/default.png";
$info = pathinfo ( $path, PATHINFO_BASENAME ); // returns default.png

Yet another solution, using preg_match()

<?php
$path = "http://domain.tld/Oppa/upload/default.png";   // or "C:\\domain.tld\Oppa\upload\default.jpg";
$pattern = '/[\/|\\\\]((?:.(?!\/|\\\\))+)$/';
if(preg_match($pattern, $path, $matches)){
    echo $matches[1];  // default.png or default.jpg
}
?>

Note: People claim to have problems using basename() with asian characters

I am supposing that if your image path will not be change from Oppa/upload/ than this Should work using explode :

$str = "Oppa/upload/default.jpeg";
$s= explode("Oppa/upload/",$str);
echo $s[1];

Another Best thing you can do with defining the relative path as a constant, so :

const path = "Oppa/upload/";
$str = "Oppa/upload/default.jpeg";
$s= explode(path,$str);
echo $s[1];

will also work.

please give reason if you are going with down vote, so that i can find my self where i am wrong for this solution. – Harshal Jul 19 '14 at 13:02
re-invents the wheel and hard-codes the file path - ergo: not useful. – Emissary Jul 19 '14 at 13:32
than there is another solution with `const` , just change at 1 place and will work everywhere. – Harshal Jul 19 '14 at 13:34
