Get Filename

[WebWatcher]

Does anybody now how i would get a name of a file/picture if i have them saved in a mysql database as the following

www.domainname.com/images/file.jpg
www.domainname.com/images/thumbs/file.jpg

I wanna just read the file.jpg from both of them

This is a quick way of doing it from what i can think:

<?php
$url = "www.domainname.com/images/file.jpg";
$part1 = expand("/", $url);
echo $part1[3];
?>

Elaborating on Jonny's, because there may be more than 1 directory:

<?php
$url = "www.domainname.com/images/file.jpg";
$part1 = expand("/", $url);
echo $part1[count($part1)-1];
?>

echo basename( "www.domain.com/path/to/file.jpg" );

 

[themoose]

echo basename( "www.domain.com/path/to/file.jpg" );

Heh. Well, you learn something new every day!

another one:

$uri = "www.domainname.com/images/file.jpg";
$parts = explode('/' , $uri);
echo end($parts);

 

[JonnyH]

echo basename( "www.domain.com/path/to/file.jpg" );

Always have to do one better ey?

It's not about doing one better, I say this all the time, and anyone who is even a novice programmer will understand: The php authors have spent years developing php, they have spent countless hours on each and every function or class you use daily to achieve everything, if these people, with an awsome amount of experience, create a function for a purpose you can be damn sure that however they are doing it is best. So if there's a function for something, like get the filename from a path or url, or format a string properly, or anything you come across, you should definately use the predefined functions written by people with collectively hundreds of years experience in programming and most importantly programming php .....

I was only messing about, but there is some neat functions like that which not a lot of people use and know about.

 

[JohnN]

theres a lot of functions like that actually, little known functions that server a highly specific purpose. just got to know them i guess.

 

[krakjoe]

Actually, they are some of the best known features of programming and not just with PHP. Basename is part of the POSIX standard ANSI C library....

#include <libgen.h>
#include <stdio.h>

int main( int argc, char *argv[]  )
{
        if( argv[1] )
        {
                puts( basename( argv[1] ) );
        }
        return 0;
}

basename exists as an executable on most unix systems because of this ^^ the above is a lot like the source ...

I maintain before you attempt to master PHP, you should have C under your belt ....
