Delete files which has the same prefix

Question

$prefix = 'something_prefix';
unlink($prefix.'.*');

the code above is not working, but I see some code like this below works just fine

unlink('*.jpg');

why? I am wonder is this going to work?

unlink('*.*');

how to delete the files which they begin with the same string? like this

same123.jpg
sametoo.png
samexxx.gif

they all begins with the string "same" but ends with different extension, how to do this?

I alread have a cheap way to do this, but I wonder if there is any better solution?

Answer 1

Try this code:

$mask = 'your_prefix_*.*';
array_map('unlink', glob($mask));

p.s. glob() requires PHP 4.3.0+
